STARTECH Single mode LC loopback plug 9/125um OS1/OS2 0dB LOOPBACKLCLC00DB

This single-mode LC loopback plug is a practical tool for checking signal continuity, insertion loss and port operation in fibre optic networks. Technicians and IT professionals can use it for fast, consistent testing of LC/UPC optical connections.

The 9/125 µm loopback adapter works with OS1 and OS2 LC/UPC cabling in point-to-point and structured installations. It complies with the IEC 61754-20 standard and the RoHS directive, making it suitable for standardised environments and controlled test tasks. Its 0 dB low-loss design and high-precision ceramic ferrules ensure clean signal transmission.

The plug helps verify transceivers, isolate faults and confirm port operation on single-mode LC switches and SFP/SFP+ devices. The slim LC connector fits dense optical port panels without blocking neighbouring ports. Its ABS housing is rated for 1000 test cycles and operates between -40 °C and 75 °C.
