Optički fiber loopback adapter DeLOCK 86923

The Optical Fiber Loopback Adapter DeLOCK 86923 is a compact SC multimode loopback designed for testing and troubleshooting fiber optic connections. It is intended to allow quick verification of transmission paths by looping the signal back into the fiber, enabling measurement of link integrity and basic diagnostics in network equipment or cabling installations.

Advantages

This loopback adapter uses OM3 multimode fiber in an OFC cable construction and an SC connector with a 125 µm core diameter. Its short 0.065 m length minimises signal loss for local loopback tests and makes it easy to carry and insert into test ports. The adapter is compatible with standard SC ports and supports straightforward loopback measurements without additional tools.

Suitable for

• Testing and troubleshooting fiber optic links
• Quick loopback verification in network equipment with SC ports
• Laboratory and on-site diagnostics of OM3 multimode cabling

How to use

Insert the SC connector of the loopback adapter into the device or patch panel SC port that you want to test. Once connected, perform your usual link test or diagnostic procedure; the adapter returns the signal into the same transceiver or interface to allow measurement of transmission capability and basic fault detection. Remove the adapter after testing and store it in a protective case or bag to prevent contamination of the SC ferrule.

Recommendations

Handle the SC ferrule carefully and keep the connector dust cap on when not in use. Clean the connector endface before insertion to avoid measurement errors. Use the adapter only with compatible SC multimode ports and avoid bending the cable beyond its minimum bend radius.
