RF Industries LC/LC Singlemode Fiber Loopback Plug
The RF Industries SUSL01LCLCXXXPX is a singlemode LC/LC loopback plug engineered for optical network diagnostics. By connecting directly to an LC-equipped transceiver or switch port, this loopback plug returns the transmitted signal back to the receiver, enabling port self-testing without an external fiber link. It is a standard tool for commissioning fiber infrastructure, verifying transceiver functionality, and troubleshooting optical link faults in data center and enterprise networks.
Key Features
- LC/LC loopback configuration for use with LC-type SFP transceivers and switch ports
- Singlemode fiber optimized for 1310nm and 1550nm wavelength testing
- Enables port-level self-test without a connected fiber span
- Useful for transceiver validation, switch commissioning, and fault isolation
