LOOPBACKLCLC00DB

LOOPBACKLCLC00DB is a single mode LC loopback plug. It is a practical tool for verifying signal continuity, insertion loss, and port function in fibre optic networks. Ideal for technicians and IT Pros, it enables fast, consistent testing across LC/UPC fibre connections. This 9/125um LC loopback adapter is compatible with OS1 and OS2 LC/UPC cabling in point-to-point and structured installations. Validate transceivers, isolate faults, and confirm port function across single mode LC switches and SFP/SFP+ devices. The 0dB low-loss design and high-precision ceramic ferrules deliver clean signalling for accurate, reliable diagnostics. The streamlined LC connector fits securely into high-density fibre arrays without blocking adjacent ports. A durable ABS housing withstands wear from repeated use and is suitable for frequent testing in data centres and edge or on-prem installations.
