1.25mm to 2.5mm Fibre Adaptor

The 1.25mm to 2.5mm Fibre Adaptor allows technicians to connect LC connectors to compatible 2.5 mm interfaces on Yamasaki fibre optic test equipment. The Yamasaki TLC supports optical light sources, optical power meters and Visible Fault Identifiers. Therefore, it provides a practical accessory for technicians working with LC connectivity.

Connect LC Fibre to Compatible Test Equipment

LC connectors use a 1.25 mm ferrule. However, many fibre testing instruments have interfaces designed to accommodate a larger 2.5 mm ferrule.

The Yamasaki TLC bridges this interface difference. As a result, technicians can connect suitable LC-terminated fibre leads to compatible testing equipment.

The adaptor changes the connection interface rather than the connector itself. Consequently, the LC ferrule remains 1.25 mm in diameter.

Applications for the Yamasaki TLC Adaptor

Optical Light Sources

An optical light source supplies a test signal at a selected wavelength. When paired with an optical power meter, it supports fibre link loss measurements.

The TLC provides LC connection capability for compatible Yamasaki light source interfaces. Therefore, it helps technicians prepare their equipment for LC-terminated test leads.

However, the adaptor does not change the source wavelength or fibre type. Technicians must still select the appropriate singlemode or multimode light source.

Optical Power Meters

An optical power meter measures the optical power arriving at its detector. In addition, a suitable source and meter combination can measure link loss against an established reference.

The TLC supports LC connectivity on compatible Yamasaki power meter interfaces. Nevertheless, technicians must select the correct measurement wavelength and follow the instrument instructions.

Visible Fault Identifiers

A Visible Fault Identifier introduces visible red light into a fibre. Consequently, it can assist with continuity checks and locating faults where escaping light is visible.

The TLC allows suitable LC connections to compatible Yamasaki Visible Fault Identifier interfaces. However, visible fault identification does not replace optical loss testing or OTDR measurements.

Selecting the Correct Testing Setup

Ferrule diameter is only one part of equipment compatibility. Therefore, technicians should also confirm the instrument interface, connector polish and required test method.

Before ordering, identify:

  • The Yamasaki instrument model.
  • The connector type on the test lead.
  • The connector polish, including PC, UPC or APC.
  • The fibre type and test wavelengths.
  • The intended measurement or fault-finding task.

Furthermore, do not assume that matching ferrule diameters makes every connector suitable. Anderson Corporation can help confirm the correct arrangement for your equipment.

For source-and-meter testing, also consider the RapidConnect Reference Cable Kit. Suitable reference leads form an essential part of the measurement setup.

Using the Fibre Adaptor

First, identify the instrument and confirm that the TLC suits its connection interface. Next, inspect and clean accessible connector end faces using suitable fibre cleaning equipment.

Fit the adaptor according to the instrument instructions. Then connect the LC lead carefully, without forcing the connector or placing tension on the cable.

For loss measurements, establish the reference using the intended testing configuration. If that configuration changes, follow the applicable procedure for checking or resetting the reference.

Finally, protect the adaptor and test leads from contamination between uses. Clean connections help reduce avoidable measurement problems.

Understanding Ferrule Sizes

The ferrule holds the fibre at the connector tip. LC connectors use a smaller ferrule than common SC, ST and FC connectors. Therefore, an LC connection requires an appropriate interface when the test instrument accepts a larger ferrule format.

Connection Compatibility and Measurement Capability

An adaptor provides a suitable physical connection. However, the instrument determines the available wavelengths, measurement range and testing functions.

Consequently, technicians should choose the instrument for the testing task and then select the required connection accessories.

Frequently Asked Questions

What does the 1.25mm to 2.5mm Fibre Adaptor do?

It enables LC connectors with 1.25 mm ferrules to connect to compatible 2.5 mm test interfaces. However, it does not physically enlarge or modify the LC ferrule.

Which Yamasaki instruments use the TLC adaptor?

The TLC supports compatible Yamasaki optical light sources, optical power meters and Visible Fault Identifiers. Therefore, provide your instrument model when ordering so Anderson Corporation can confirm the required setup.

Does the adaptor change singlemode fibre into multimode fibre?

No. The adaptor changes the connection interface only. Consequently, the fibre type and instrument wavelengths must still suit the test.

Can I use it with APC connectors?

Confirm compatibility before connecting an APC lead. Ferrule diameter alone does not establish whether the connector polish suits the instrument interface.

Do I need reference cables as well?

For optical loss testing, you need suitable reference leads and the correct referencing procedure. Therefore, select the adaptor, light source, power meter and reference cables as a coordinated testing setup.
