The Yamasaki Y91 is a compact, battery-powered core alignment fusion splicer designed for individual-fibre installation, termination, maintenance and restoration. Its six-motor core alignment system, dual-camera imaging and reversible 5-inch colour touchscreen support precise, efficient operation in both field and workshop environments.
With automatic and manual operating modes, fast splice and heating cycles, and a complete portable field package, the Y91 delivers reliable performance across compatible singlemode, multimode and speciality optical fibres.
The Yamasaki Y91 Core Alignment Fusion Splicer provides six-motor core-to-core alignment for individual-fibre installation, termination, maintenance and restoration work. In addition, its portable, battery-powered design supports technicians working with compatible singlemode, multimode, dispersion-shifted and non-zero dispersion-shifted optical fibres across commercial, industrial, campus and telecommunications networks.
Designed for both field and workshop use, the Y91 combines dual-camera fibre imaging, automatic and manual operation, a reversible 5-inch colour touchscreen and a typical six-second splice cycle for standard singlemode fibre. Furthermore, the complete field package includes the Y18 precision fibre cleaver, fibre-preparation tools, power accessories and a protective carrying case.
Unlike a ribbon fusion splicer, which joins several fibres in a compatible ribbon during one cycle, the Y91 focuses on flexible and precise individual-fibre splicing. Therefore, it suits loose-tube cable installation, pigtail termination, fibre-network maintenance, cable restoration and projects involving varied fibre types.
Optical fibres can appear perfectly positioned at the cladding while their light-carrying cores remain slightly offset. Consequently, a core alignment fusion splicer uses fibre images and motorised positioning to align the cores before completing the fusion cycle.
The Yamasaki Y91 uses six motors to control fibre positioning and achieve core-to-core alignment. Meanwhile, two high-sensitivity CMOS cameras provide views across both fibre axes. As a result, the machine can assess fibre position, cleave condition and alignment before fusion.
This capability provides valuable flexibility when technicians work with different fibre batches, older infrastructure, repair sections or compatible fibres whose core geometry may not align perfectly through cladding position alone. However, sound fibre preparation remains essential. Therefore, the technician must strip, clean and cleave each fibre correctly before loading it into the machine.
The Y91 brings together the principal functions required for regular individual-fibre work in one portable field package. Moreover, its combination of core alignment, fibre imaging, automatic operation and battery power supports varied installation and maintenance workloads.
Six-motor positioning supports core-to-core alignment across both viewing axes. Consequently, the machine can adjust fibre position before applying the fusion arc rather than relying solely on fixed V-groove placement.
Additionally, motorised positioning can help technicians manage compatible fibres from different batches or sections of existing infrastructure. Nevertheless, the selected splice program and preparation method must suit the fibres involved.
Two CMOS cameras provide clear views of the prepared fibres. In addition, the display offers up to 250× magnification in single-axis view and 125× magnification in dual-axis view. Therefore, technicians can inspect alignment and respond to preparation warnings before completing the joint.
Clear fibre images also support better process control. For example, an operator may identify an unacceptable cleave, contamination or incorrect fibre position before the machine applies the fusion arc.
Automatic modes simplify routine work with known fibre types. Meanwhile, manual control gives experienced technicians greater flexibility when a project or fibre combination requires closer supervision.
However, manual control does not remove the need for approved procedures. Instead, organisations should define who may adjust programs and how they will document any changes.
The machine specifies a typical six-second splice time for standard singlemode fibre and an 18-second sleeve-heating time. Although preparation and tray management also affect total production time, these cycles support efficient field workflows when technicians follow a consistent process.
Furthermore, total productivity depends on much more than the fusion cycle. Fibre identification, stripping, cleaning, cleaving, loading, inspection, sleeve heating, cooling and tray routing all contribute to the time required for each completed splice.
The 5,200 mAh lithium-ion battery supports approximately 250 splice-and-heat cycles under the manufacturer’s typical test conditions. As a result, technicians can complete substantial field work where mains power remains unavailable or inconvenient.
Nevertheless, actual battery performance can change with temperature, battery condition and operating practices. Therefore, teams should assess the complete expected workload before travelling to remote or critical sites.
The supplied kit brings together the splicer, precision cleaver, preparation tools, battery, power accessories and transport case. Therefore, buyers can assess a complete operating package rather than treating the fusion splicer as an isolated machine.
However, the standard package may not include every holder, consumable or spare component required for a particular project. Accordingly, buyers should confirm the current inclusions when requesting a quotation.
The Y91 supports individual optical fibres across a broad range of compatible applications. Specifically, the listed fibre categories include:
The machine accommodates cladding diameters from 80 to 150 µm and coating diameters from 160 to 3,000 µm. Furthermore, it supports cleaved fibre lengths from 5 to 16 mm.
Nevertheless, broad category support does not guarantee that every speciality fibre or coating construction will suit the same holder, preparation method or splice program. Therefore, confirm the exact fibre, coating diameter, holder arrangement, cleave length and splice-protection sleeve before purchasing the machine for a particular project.
Additionally, organisations that expect to join dissimilar fibres should evaluate those combinations carefully. For instance, differences in mode-field diameter, glass composition or core geometry can affect splice performance and bidirectional OTDR results.
The Y91 suits organisations that regularly install, terminate, maintain or restore individual-fibre networks. In particular, its flexible field format supports varied applications rather than one specialised cable architecture.
Installers commonly splice individual fibres from loose-tube cables onto connectorised pigtails inside fibre enclosures. Accordingly, the Y91 supports this workflow across compatible singlemode and multimode systems.
Moreover, individual-fibre operation allows technicians to prepare and manage each fibre separately. This flexibility can prove useful when cable constructions, fibre counts and enclosure layouts vary between projects.
Fusion splicing pigtails provides a controlled method of creating connectorised fibre terminations. First, the technician prepares the cable fibre. Next, they join it to the correct pigtail and protect the splice inside the enclosure tray.
As a result, installers can combine factory-terminated connector end faces with fusion-spliced cable fibres. However, correct fibre identification, polarity management and tray routing remain essential throughout the process.
The portable design suits backbone links between communications rooms, buildings and campus facilities. In addition, individual-fibre capability supports moves, additions, upgrades and repair work across established networks.
For example, technicians may use the Y91 when terminating new backbone cables or restoring damaged links. Likewise, the machine can support staged network expansions where crews splice only the fibres required for each project phase.
Industrial sites may require splicing inside communications rooms, roadside cabinets, plant areas or temporary field shelters. Consequently, the Y91’s battery operation, reversible display and compact field package support varied working environments.
However, technicians must still protect this precision equipment from dust, moisture and impact. Therefore, field procedures should include a stable work platform, suitable environmental protection and clean fibre-preparation practices.
Fibre-connected CCTV, access-control and perimeter systems often use low- or moderate-count cables across distributed locations. Therefore, a portable individual-fibre machine can support both new construction and fault restoration.
Furthermore, many security networks extend into locations where mains power or workshop facilities remain unavailable. In these cases, battery-powered operation can simplify deployment and repair work.
Maintenance teams may encounter different fibre types, cable ages and network architectures. Consequently, core-alignment capability, automatic and manual programs, stored splice records and portable power can support both planned maintenance and emergency repairs.
Nevertheless, technicians should confirm fibre compatibility before joining new cable sections to older infrastructure. Additionally, bidirectional testing may be necessary where differences between fibre types influence OTDR measurements.
Restoration work demands flexibility and reliable equipment availability. Therefore, the Y91 can form part of a prepared response kit containing compatible holders, spare electrodes, cleaver blades, protection sleeves, cleaning materials and charged batteries.
Additionally, teams should inspect the complete kit at planned intervals. Otherwise, a missing low-cost accessory may prevent technicians from using an otherwise operational fusion splicer during an emergency.
The manufacturer lists the following typical average splice-loss values:
| Fibre type | Typical average splice loss |
|---|---|
| Singlemode | 0.02 dB |
| Multimode | 0.01 dB |
| Dispersion-shifted | 0.04 dB |
| Non-zero dispersion-shifted | 0.04 dB |
These figures provide a useful equipment reference. However, actual results depend on fibre compatibility, preparation quality, cleave condition, program selection, electrode condition, arc calibration, environmental conditions and operator technique.
After fusion, the Y91 analyses the fibre image and provides an estimated splice loss. Therefore, this estimate can support process control by prompting the technician to inspect or repeat a questionable joint. Nevertheless, the displayed figure does not measure end-to-end optical performance.
Consequently, technicians must complete the optical testing required by the project specification. Depending on the network and acceptance criteria, this testing may include insertion-loss testing with a light source and power meter, OTDR testing, or both.
Moreover, technicians should interpret OTDR splice results carefully when joining dissimilar fibres. Differences in backscatter characteristics can produce different apparent loss values when testing the same splice from opposite directions. Therefore, bidirectional measurement and averaging may be required.
A reliable splice depends on the complete process rather than the machine alone. Therefore, technicians should follow a controlled sequence:
The Y91 provides 40 groups of splicing programs. Consequently, the machine can apply suitable fusion parameters to supported fibre categories and operating requirements.
Automatic operation can simplify repeat work where technicians know the fibre type and required configuration. Conversely, manual operation provides additional control for trained users who need to inspect settings or manage less routine applications.
Before production work begins, organisations should establish approved programs for their common fibres. Additionally, they should document the required preparation method, sleeve type, heater setting, arc-calibration procedure and acceptance criteria. As a result, teams can improve consistency across technicians and projects.
Where two dissimilar fibres must be joined, confirm their compatibility before work begins. In particular, mode-field diameter, glass composition and other geometric differences can affect splice behaviour. Furthermore, these differences can influence bidirectional OTDR results even when the physical joint performs correctly.
Fusion conditions can change with altitude, temperature, humidity, electrode wear, contamination and fibre type. Therefore, technicians should complete arc calibration in accordance with the Y91 operating instructions and the organisation’s documented procedure.
The machine has a specified operating temperature range of −20°C to +50°C. Nevertheless, that range does not remove the need for sound field practices. Instead, technicians should protect the machine from rain, airborne dust, strong wind, condensation and physical impact.
Moving precision equipment between markedly different environments may also require acclimatisation. For example, condensation can form when a cold machine enters a warm, humid space. Consequently, technicians should allow the equipment to stabilise before preparing and splicing fibres.
Additionally, strong wind can contaminate prepared fibre ends or affect the fusion environment. Therefore, crews working outdoors should use a suitable shelter or enclosure.
The Y91 provides four heating-program selections and supports 40 mm and 60 mm splice-protection sleeves. In addition, its stated typical sleeve-heating time is 18 seconds.
Select the protection sleeve to suit the fibre, cable construction and splice tray. Furthermore, confirm that the selected heating program matches the sleeve. After heating, allow the sleeve to cool in a stable position before routing it into the tray.
The heater cannot correct poor fibre preparation or a defective splice. Instead, it protects a joint that the technician has already inspected and accepted. Therefore, operators should never use the completed protection sleeve as evidence that the optical joint meets the required performance criteria.
The supplied 5,200 mAh lithium-ion battery supports approximately 250 splice-and-heat cycles under typical stated conditions. However, actual field capacity can vary with temperature, battery age, display use, heating cycles and operating practices.
Before remote work, teams should:
For emergency restoration, a documented charging schedule can prevent an otherwise capable machine from arriving on site with insufficient power. Likewise, regular battery-condition checks can help organisations identify declining capacity before it affects field operations.
The Y91 Core Alignment Fusion Splicer includes a reversible 5-inch colour LCD touchscreen. Consequently, technicians can orient the interface around their working position. In addition, physical keypad controls provide an alternative method of operating the machine.
Clear fibre images help users assess preparation and alignment. However, display quality provides the greatest value when technicians understand the warnings and know when to reject a cleave or repeat a splice. Therefore, operator training remains an important part of the equipment purchase.
Furthermore, organisations should consider the practical work environment. For instance, physical controls may prove useful when operators wear gloves or when field conditions make touchscreen operation less convenient.
The Y91 stores up to 10,000 splice results. Therefore, stored process information can support internal quality control, troubleshooting and project traceability.
In addition, USB 2.0 connectivity supports result transfer and software updates. Before relying on exported information, however, confirm the available fields, file format, software requirements and internal data-retention process.
Splice records can help identify trends such as repeated preparation warnings or changing estimated losses. Nevertheless, they do not replace the formal optical test results required to certify a completed fibre link.
Instead, organisations should treat the stored information as process and workmanship data. For example, a rising pattern of estimated loss may prompt technicians to inspect the electrodes, clean the V-grooves, examine the cleaver or repeat arc calibration.
The Y91 measures 156 × 141 × 156 mm and weighs 2.45 kg including the battery. Consequently, its compact format supports transport between sites and operation in communications rooms, cabinets and temporary work areas.
However, the complete field setup still requires a stable, clean work surface. Technicians also need space for the cleaver, stripper, cleaning materials, protection sleeves and fibre management. Therefore, buyers should assess the entire operating kit and work platform rather than considering the machine dimensions alone.
Furthermore, the protective case should accommodate the equipment and accessories required for the intended work. A compact splicer provides limited value if technicians must carry several poorly organised cases to every site.
The supplied Y18 precision fibre cleaver forms a critical part of the splicing system. After all, a fusion splicer cannot reliably join fibre ends with excessive angles, chips, cracks or contamination.
Therefore, operators should keep the cleaver clean, rotate or adjust the blade as instructed and replace the blade when it reaches its service limit. Organisations should also stock suitable replacement blades so that a low-cost component does not stop field production.
When troubleshooting repeated cleave warnings, first inspect the preparation method, stripper condition and cleaning process. Next, check the blade position, fibre placement and overall cleaver condition. Consequently, technicians can eliminate common preparation faults before assuming that the fusion splicer has developed a problem.
The supplied package includes the principal equipment required for individual-fibre field splicing:
However, package contents can change. Therefore, confirm the current inclusion list when requesting a quotation. Additionally, identify any extra holders, batteries, cleaver blades, cleaning tools, protection sleeves or consumables required for the intended fibre system.
By reviewing the complete package, buyers can compare the actual cost of establishing an operational field kit. Otherwise, missing tools or accessories may add unexpected costs after the initial purchase.

However, actual performance varies with fibre type, preparation, settings, environment, maintenance and operating practices. Therefore, confirm current specifications and package contents before ordering.
The Y91 and Y120 address different fibre formats and workloads. Therefore, choosing between them starts with the cable architecture rather than a generic comparison of machine specifications.
| Requirement | Yamasaki Y91 | Yamasaki Y120 |
|---|---|---|
| Primary fibre format | Individual fibre | Compatible ribbon fibre |
| Principal alignment intent | Core-to-core alignment of individual fibres | Multi-fibre ribbon alignment and mass fusion |
| Typical work | Loose-tube fibres, pigtails, maintenance and restoration | High-count conventional or rollable ribbon systems |

Choose the Y91 when technicians primarily splice individual fibres across varied installation, termination, maintenance and repair work. By comparison, organisations working extensively with compatible high-count ribbon cable should assess the Yamasaki Y120 ribbon fusion splicer.
Some networks contain both individual-fibre and ribbon architectures. In that case, separate machines may provide better operational coverage than expecting one platform to optimise every task. Moreover, separate equipment can improve availability when several crews need to work simultaneously.
A fusion splicer requires routine care throughout its working life. In particular, electrodes, V-grooves, clamps, cameras, holders and the precision cleaver can all affect performance.
The Y91 specifies an electrode life of 4,000 splices. However, technicians should follow the manufacturer’s inspection, cleaning, stabilisation, calibration and replacement procedures rather than treating the stated count as the only maintenance trigger.
Before purchase, consider:
Local assistance and readily available parts can reduce downtime across installation and restoration work. Therefore, buyers should evaluate support arrangements alongside the machine’s technical specifications.
Furthermore, organisations responsible for critical infrastructure should consider how they will continue working while the machine undergoes servicing or repair. Depending on the workload, a backup machine or access to hire equipment may reduce operational risk.
Anderson Corporation can help customers assess the Y91 package, intended fibres, accessories and support requirements before purchase.
The Y91 Knowledge Centre supports organisations that use individual-fibre fusion splicing across installation, termination, maintenance and restoration work. Accordingly, each technical article addresses a defined informational question, while the Y91 page remains the commercial Authority Hub for core alignment equipment.
Learn how preparation, cleaning, precision cleaving, alignment, fusion, splice protection and optical testing contribute to reliable fibre joints.
Compare core alignment, cladding alignment and ribbon fusion splicers. Then, assess fibre compatibility, battery capacity, field features, service support and total ownership cost.
As the Knowledge Centre expands, additional articles should focus on individual-fibre subjects such as core alignment, fibre preparation, precision cleaving, pigtail termination, arc calibration, field maintenance, splice-loss troubleshooting and emergency restoration.
By contrast, ribbon preparation and mass-fusion subjects will sit within the separate Y120 Knowledge Centre. Therefore, each product hub will retain clear commercial and technical ownership of its intended fibre format.
Selecting a core alignment fusion splicer involves more than comparing fusion speed, battery capacity and estimated splice loss. Instead, technicians must consider alignment technology, fibre compatibility, preparation quality, field conditions, testing requirements and the type of work they complete.

A core alignment fusion splicer uses fibre images and motorised positioning to align the light-carrying cores of two prepared optical fibres before an electrical arc fuses them. By comparison, other systems may position fibres principally by their cladding.
The Y91 uses six motors for core-to-core alignment of individual fibres. Consequently, the machine can adjust fibre position across its viewing axes before completing the fusion cycle.
The Y91 primarily serves individual-fibre splicing. Therefore, it suits loose-tube cable installation, pigtail termination, maintenance and restoration. By contrast, organisations that need repeat multi-fibre mass fusion across compatible ribbon systems should assess a dedicated ribbon fusion splicer such as the Yamasaki Y120.
The stated compatible categories include singlemode, multimode, dispersion-shifted, non-zero dispersion-shifted and erbium-doped fibres. In addition, the machine may support other fibres within its dimensional and program limits. However, buyers should confirm the exact fibre, dimensions, holder and program before purchase.
The manufacturer specifies a typical six-second splice cycle for standard singlemode fibre. However, preparation, loading, inspection, sleeve heating, cooling and tray routing add to the complete production time.
The stated typical heating time is 18 seconds. Nevertheless, the actual workflow depends on the selected sleeve, heater program and working conditions.
The 5,200 mAh battery supports approximately 250 splice-and-heat cycles under typical stated conditions. However, temperature, battery condition and operating practices can affect actual capacity.
No. Instead, the Y91 estimates splice loss from fibre images and splice analysis. Therefore, technicians still need to complete the optical tests required by the project specification to verify the finished link.
Yes. The machine stores up to 10,000 splice results. In addition, it provides USB 2.0 connectivity for result transfer and software updates.
The Y91 supports 40 mm and 60 mm splice-protection sleeves and provides four heater-program selections. However, users must still confirm that the selected sleeve suits the fibre system and splice tray.
Yes. The package includes the Y18 precision fibre cleaver. Nevertheless, customers should confirm the complete current package contents when requesting a quotation.
The Y91 supports field work and has a stated operating range of −20°C to +50°C. However, technicians must still protect the machine and prepared fibres from rain, dust, wind, condensation, contamination and impact.
The stated warranty period is 12 months. Therefore, confirm the current warranty terms, exclusions and support process when ordering.
