DIN Rail Fibre Optic Enclosure

The DIN Rail Fibre Optic Enclosure provides a compact termination and splicing point for fibre optic connections inside industrial cabinets, control panels and telecommunications installations. Designed for standard DIN rail systems, the RapidConnect 12D helps installers manage incoming fibre cable, fusion splices, pigtails, adaptors and patch leads within one aluminium enclosure.

Because space is often limited inside equipment cabinets, the enclosure measures only 38 × 138 × 140 mm. However, its internal splicing module can accommodate configurations for 6, 12 or 24 optical fibres. As a result, the 12D supports a range of compact fibre networks without requiring a conventional wall-mounted or rackmount enclosure.

Anderson Corporation can also configure the RapidConnect 12D to suit the required fibre type, connector format, polish and fibre count. Therefore, installers can specify an unloaded enclosure or request a coordinated, fully loaded assembly for the intended network.

What Is a DIN Rail Fibre Optic Enclosure?

A DIN Rail Fibre Optic Enclosure provides a protected location for terminating and distributing optical fibres within an equipment cabinet or control panel. Instead of occupying rack space, the enclosure attaches to a compatible DIN rail alongside other industrial components.

Incoming fibre cable enters the enclosure through one of the two available cable ports. Inside the enclosure, the cable fibres can be fusion spliced to colour-coded pigtails. The pigtail connectors then connect to adaptors installed in the enclosure’s adaptor interface.

Patch leads connect the internal fibre termination to switches, media converters, industrial controllers or other active equipment. Consequently, the enclosure creates an organised transition between the incoming fibre cable and the equipment it serves.

The RapidConnect 12D can accommodate ST, SC, SC/APC, LC and LC/APC connection formats. However, the final adaptor capacity depends on the selected connector type and adaptor arrangement. Therefore, fibre count, adaptor count and connector configuration must be confirmed when ordering.

RapidConnect 12D Compact Enclosure Design

The RapidConnect 12D has been developed for installations where equipment-cabinet space is limited. Its shallow profile allows the enclosure to fit into suitable control panels and communications cabinets without using a 19-inch equipment rack.

In addition, the enclosure uses aluminium construction with an electrostatic finish. This construction produces a lightweight housing while providing a dedicated enclosure for the internal fibre components.

The complete enclosure weighs approximately 0.3 kg. Therefore, it adds little weight to the equipment cabinet while still bringing splicing, termination and patching functions together.

Fibre Capacity and Adaptor Configuration

The RapidConnect 12D is commonly described as a 24-port DIN rail enclosure. However, installers should not assume that every connector arrangement provides 24 identical front-facing adaptor positions.

The internal splicing module can accommodate 6, 12 or 24 optical fibres. In contrast, the number of available adaptor connections depends on the selected connector family and whether the enclosure uses Simplex, Duplex or Quad adaptors.

For example, an LC-based configuration can provide more fibre connections within a given interface area than a larger connector format. An SC configuration, meanwhile, requires more physical space for each adaptor. Therefore, Anderson Corporation confirms the enclosure layout against the complete termination requirement.

The configuration process should consider:

  • Required fibre count
  • OS2 or multimode fibre
  • Connector type
  • UPC or APC polish
  • Simplex, Duplex or Quad adaptor format
  • Pigtail requirements
  • Fusion-splice capacity
  • Patch-lead connection requirements
  • Cable diameter and entry arrangement

By confirming these details first, the selected enclosure can match the network rather than relying on the product name alone.

Internal Fibre Splicing and Termination

The internal splicing module provides a dedicated location for managing fusion-spliced fibres. During installation, the technician prepares the incoming cable, routes the fibres into the enclosure and splices them to the required pigtails.

The completed splices must remain protected and correctly arranged within the available space. Likewise, the fibre must maintain a suitable bend radius throughout the enclosure. Careful fibre routing helps prevent stress, sharp bends and unnecessary congestion.

The pigtails then connect to the selected adaptors. As a result, the external side of the adaptor interface provides an accessible connection point for compatible patch leads.

This arrangement separates the permanent incoming cable from the removable equipment connection. Therefore, technicians can connect or replace patch leads without disturbing the underlying fusion splices.

Two Cable Entry and Exit Ports

The RapidConnect 12D includes two cable entry and exit ports. These ports allow installers to introduce the incoming fibre cable and arrange the enclosure around the intended cable path.

For example, one port may carry an incoming distribution cable. Alternatively, the two ports may support another suitable routing arrangement, subject to cable size, fibre count and installation requirements.

However, the cable entries do not remove the need for suitable cable preparation and retention. The installer must ensure that the cable remains secure and that mechanical loads do not transfer to the individual fibres or splices.

Before installation, the technician should confirm:

  • Cable outside diameter
  • Cable construction
  • Required entry direction
  • Available cabinet clearance
  • Fibre preparation length
  • Internal routing path
  • Bend-radius requirements
  • Required cable retention method

These checks help determine whether the 12D suits both the cable and the available enclosure space.

Connector and Adaptor Options

The RapidConnect 12D supports several common fibre connector formats. Consequently, the enclosure can be configured for different industrial, telecommunications and building-network requirements.

LC Connections

LC connectors provide a compact connection format. Therefore, they suit applications where the required fibre density must fit within a limited interface area.

LC adaptors may support UPC or APC connector polish, depending on the specified system. However, UPC and APC connectors must not be connected together. The complete link must use compatible connector and adaptor types.

SC Connections

SC connectors use a larger push-pull body and remain common across telecommunications and building fibre networks. The enclosure can accommodate SC and SC/APC configurations, subject to the required adaptor layout.

As with LC connectors, the polish must match across the connection. Therefore, installers should confirm whether the network requires SC/UPC or SC/APC before the enclosure is assembled.

ST Connections

ST connectors may still appear in established industrial, instrumentation and legacy fibre networks. For this reason, the 12D can also support suitable ST adaptor configurations.

Nevertheless, connector selection should reflect the active equipment and the wider network specification. It should not be based solely on what can physically fit into the enclosure.

OS2 and Multimode Fibre Configurations

The enclosure can support both singlemode and multimode fibre terminations when fitted with the correct components. However, the pigtails, adaptors and patch leads must match the optical system.

OS2 networks require compatible singlemode pigtails and patch leads. Multimode networks, meanwhile, require the correct multimode fibre category and corresponding components.

Colour coding can help identify the installed fibre and connector system. Even so, installers should verify the component specifications rather than relying only on colour.

Anderson Corporation can configure the enclosure around the required:

  • Fibre category
  • Fibre count
  • Connector format
  • Connector polish
  • Adaptor arrangement
  • Pigtail type
  • Pigtail length
  • Splice-protection requirements

Therefore, providing a complete termination schedule at the quotation stage reduces uncertainty and helps establish the correct assembly.

Unloaded and Fully Loaded Options

The RapidConnect 12D may be supplied as an unloaded enclosure or configured with selected termination components.

An unloaded enclosure allows the installer or system integrator to select and fit the required internal components. This approach may suit organisations that hold their own adaptors, pigtails and splice-protection hardware.

A configured enclosure can instead arrive with compatible components selected for the project. Depending on the requested assembly, these components may include adaptors, colour-coded pigtails and associated splice-management hardware.

A fully loaded option can reduce component-selection work before installation. More importantly, it helps ensure that the adaptor format, pigtail specification and intended fibre count form a coordinated assembly.

However, “fully loaded” does not describe one universal configuration. Every project may require a different fibre type, connector, polish and capacity. Therefore, the required bill of materials must be confirmed before supply.

Industrial Automation Applications

Industrial control cabinets often contain power supplies, terminal blocks, controllers and communications equipment mounted on DIN rail systems. The RapidConnect 12D allows fibre termination to sit within this established cabinet format.

Fibre links can connect control systems across buildings, production areas or equipment zones. In addition, fibre provides electrical isolation between networked devices because the optical path does not conduct electricity.

The enclosure may suit connections associated with:

  • Industrial Ethernet networks
  • Programmable logic controllers
  • Supervisory control systems
  • Remote input/output equipment
  • Industrial switches
  • Media converters
  • Process-control communications
  • Building automation systems

However, the enclosure itself does not determine whether the overall installation suits a particular industrial environment. The designer must also consider the cabinet rating, location, temperature, contamination, vibration and wider installation requirements.

Telecommunications and Building Networks

The DIN Rail Fibre Optic Enclosure can also serve compact telecommunications and building-network installations. For example, it may provide a local fibre termination point inside a communications cabinet where a rackmount enclosure would occupy unnecessary space.

Potential applications include:

  • Telecommunications cabinets
  • Commercial building networks
  • Security and surveillance networks
  • Campus fibre links
  • Fibre-to-the-home infrastructure
  • CATV systems
  • Equipment-room connections
  • Compact fibre distribution points

Because the enclosure can support several connector formats, it can be aligned with the equipment used at the termination location. Nevertheless, the designer should select the connector system before specifying the adaptor interface.

Planning the Correct 12D Configuration

A suitable configuration begins with the optical network rather than the enclosure alone. First, identify the number of fibres that require termination. Next, confirm the fibre category, connector type and polish.

The designer should then consider the incoming cable construction and entry requirements. Finally, the adaptor arrangement, pigtails and patch leads can be matched to the active equipment.

The following information should accompany an enquiry:

  1. Required fibre count
  2. OS2 or multimode fibre category
  3. LC, SC or ST connector preference
  4. UPC or APC polish
  5. Simplex, Duplex or Quad arrangement
  6. Incoming cable type and diameter
  7. Pigtail requirements
  8. Unloaded or fully loaded supply
  9. Patch-lead requirements
  10. Required quantity

If the final configuration remains uncertain, Anderson Corporation can review these details before quotation.

DIN Rail Enclosure Installation Considerations

Before mounting the enclosure, confirm that the cabinet provides enough space for the enclosure body, incoming cable and connected patch leads. In addition, allow room to open and access the enclosure during installation and future maintenance.

The DIN rail must support the enclosure securely. Likewise, the incoming cable should approach the entry point without a tight bend or unsupported load.

During fibre preparation, the installer should avoid excessive stripping lengths and uncontrolled fibre loops. Instead, each fibre should follow an organised route through the enclosure.

After splicing, the technician should place the protected splices into the internal splicing module. The pigtails can then be routed to their corresponding adaptors. Finally, the completed connections should be identified and tested according to the project requirements.

Installation should be completed by technicians with the appropriate fibre preparation, splicing, inspection and testing skills.

Fibre Management and Maintenance

Compact enclosures require disciplined fibre management. Although the 12D supports up to 24 fibres within a small housing, available space must be used carefully.

During installation, technicians should:

  • Maintain the fibre manufacturer’s minimum bend radius
  • Protect completed fusion splices
  • Avoid crossing fibres unnecessarily
  • Keep connector end faces clean
  • Match each pigtail to the correct adaptor
  • Label connections clearly
  • Prevent cable loads from reaching the fibres
  • Confirm that the enclosure closes without pinching fibre

Furthermore, technicians should inspect and clean connector end faces before making each connection. Contaminated connectors can increase insertion loss and may damage mating surfaces.

Future maintenance should focus on the affected connection rather than disturbing the entire fibre arrangement. Therefore, accurate labelling and orderly routing become particularly important inside a compact enclosure.

When Should You Choose a Larger Enclosure?

The RapidConnect 12D suits compact termination requirements, but it will not suit every fibre installation. A larger wall-mount or rackmount enclosure may provide a better option when the network requires more fibres, more internal working space or greater patching access.

Consider a larger enclosure when:

  • Fibre capacity exceeds the available 12D configuration
  • The cable requires more entry space
  • Multiple large cables must enter the same enclosure
  • The installation requires extensive fibre storage
  • Technicians need frequent patching access
  • The site already uses a 19-inch rack
  • Future network expansion requires additional capacity

Anderson Corporation supplies a broader range of RapidConnect fibre optic enclosures for wall-mount, rackmount and other termination requirements.

Why Specify the RapidConnect 12D?

The RapidConnect 12D brings fibre splicing and connector access into a compact DIN rail format. Therefore, it can provide a practical alternative to a conventional rackmount or wall-mount enclosure when space and capacity requirements align.

Key product characteristics include:

  • Compact 38 × 138 × 140 mm enclosure
  • Aluminium construction
  • Electrostatic finish
  • Low 0.3 kg weight
  • Standard DIN rail mounting format
  • Two cable entry and exit ports
  • Internal splicing arrangements for 6, 12 or 24 fibres
  • Compatibility with ST, SC, SC/APC, LC and LC/APC connections
  • Simplex, Duplex and Quad adaptor options
  • Unloaded or project-specific configured supply

Most importantly, Anderson Corporation can match the termination components to the specified optical network. This approach helps avoid incompatible connector formats, incorrect polish types and unsuitable adaptor arrangements.
