Our customer required reliable 160 km optical transmission between two substations. After several weeks of operation, no CRC errors or unexpected link drops have appeared. Installation was straightforward, and compatibility with different vendor switches exceeded expectations. This is now our preferred 1G BiDi SFP for long-distance projects. =]

We purchased 60 pieces for a campus fiber backbone upgrade connecting multiple remote buildings. Every LS-BL49551G-A6C module established a stable 1.25Gbps link over existing single-mode fiber. DOM values matched our optical meter closely, making preventive maintenance much easier. The OEM coding was recognized by both Cisco and HPE switches. Overall deployment was smooth and downtime was minimal. :)

We tested these modules between MikroTik, Cisco Catalyst, Aruba and Ruijie switches before placing a larger order. Every link negotiated immediately without firmware complaints. DDM information reports temperature, voltage, TX and RX power correctly, helping our engineers monitor long-distance fiber health remotely. Happy with the purchase. ^^
