Loopback
C-LIGHT Loopback device (fiber optic loopback) is a critical testing tool in optical communication networks, enabling self-checking and fault localization by redirecting optical signals from the transmitter (TX) directly to the receiver (RX). Compatible with LC, SC, FC, MTP/MPO connectors and single/multi-mode fibers (PC/APC interfaces), it is widely used in 40G/100G/200G/400G/800G networks, data center interconnects, and optical module performance validation. Key capabilities include detecting power loss, validating transceiver sensitivity, and assessing link integrity, featuring low loss, millisecond-level response, and AI-driven intelligent operations
