DeLOCK 86922 SC Optical Fibre Loopback Adapter

The Optical Fiber Loopback Adapter SC DeLOCK 86922 is a compact SC loopback designed for multi-mode fiber connections. It is intended for testing and troubleshooting fiber optic links by reflecting optical signals back to the transmitting device, allowing measurement of transmission capability and verification of connection integrity. The adapter has a beige housing and small dimensions (25 mm × 65 mm × 11 mm), making it easy to carry and install in test setups.

Advantages

This SC loopback adapter provides a simple and reliable way to test fiber optic transceivers and cabling without additional equipment. Its SC connectors match standard multi-mode ports, enabling direct insertion into fiber ports to perform loopback tests. The compact size and straightforward design reduce setup time during diagnostics and troubleshooting.

Suitable for

• Testing multi-mode fiber transceivers
• Verifying fiber optic link transmission capability
• Troubleshooting and diagnostic checks in fiber networks
• Laboratory and field measurement setups

How to use

Insert the SC loopback adapter into the SC port of the device or transceiver you wish to test, ensuring a secure connection. Once inserted, transmit a test signal from the device; the adapter reflects the optical signal back to the transmitter so you can measure loopback results with your diagnostic equipment or built-in test functions. Remove the adapter after testing and store it in a dry, dust-free place.

Recommendations

Use this adapter only with compatible SC multi-mode ports and follow standard fiber handling practices: avoid touching connector endfaces, keep dust caps on when not in use, and clean connectors before insertion to ensure accurate test results.
