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. =]

Deployed over an existing carrier fiber route connecting two regional data centers. Despite multiple patch panels in the path, the optical budget remained sufficient and the link stayed stable under continuous traffic. DOM diagnostics simplified acceptance testing and reduced troubleshooting time considerably. We'll definitely reorder for future infrastructure expansion. :))

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. ^^

Shipping took a couple of extra days because of customs clearance. The optics themselves performed exactly as expected with stable 160 km transmission, so no complaints about quality. :)

This 1490nm TX / 1550nm RX BiDi SFP replaced several aging optics in our ISP access network. Optical power remained well within specification after continuous operation, and the commercial operating temperature of 0°C to 70°C fits our indoor POP environment perfectly. We especially appreciate the simplex LC interface because it reduced fiber usage while maintaining excellent signal quality.
