General Information

This Single Mode LC Loopback Plug is a practical tool for verifying signal continuity, insertion loss, and port function in fiber optic networks. Ideal for technicians and IT Pros, it enables fast, consistent testing across LC/UPC fiber connections.

Test Single Mode Connections

This 9/125um LC Loopback Adapter is compatible with OS1 and OS2 LC/UPC cabling in point-to-point and structured installations. IEC and RoHS compliance ensures readiness for standardized deployments and testing in regulated environments.

Accurate Signal Diagnostics
