Questions & Answers

Ask a Question
No data
  • Q: Can I use this module for an outdoor fiber link around 70–80km? By A***r on 2026-04-26

    A: Yes. It is designed for up to 80km transmission over single-mode fiber. As long as the total optical loss is within the link budget, it is suitable for outdoor cabinets, campus networks, telecom backhaul, and long-distance enterprise connections. By admin on 2026-04-26

  • Q: Is DOM/DDM supported for optical diagnostics? By S***n on 2025-05-22

    A: Yes. The module supports Digital Optical Monitoring (DOM/DDM), allowing you to monitor transmit power, receive power, temperature, supply voltage, and laser bias current through your switch. By admin on 2025-05-22

  • Q: Can this 1G BiDi SFP work with Cisco, Juniper, Aruba, or MikroTik switches? By W***z on 2024-10-28

    A: Yes. OEM coding is available for major switch vendors. Just specify your equipment brand before ordering, and the module will be programmed for plug-and-play compatibility. By admin on 2024-10-28

  • Q: Can it connect to another vendor's 1270nm-TX/1330nm-RX BiDi SFP? By L***z on 2024-07-29

    A: Yes. As long as the remote transceiver uses the complementary wavelength pair (1270nm TX / 1330nm RX), has the same Gigabit Ethernet standard, and the link budget is compatible, they can communicate normally even if the brands are different. By admin on 2024-07-30

We deployed these 1G BiDi SFP modules between two municipal buildings about 72km apart. DOM monitoring helped us verify optical power before putting the circuit into production. Compatible with our Cisco and Juniper switches without any manual configuration. Link has been stable for weeks with zero packet loss. Great replacement for OEM optics and much better pricing. :)

Using these for telecom backhaul between outdoor cabinets. The 80km reach and 1330nm-TX/1270nm-RX wavelength combination matched our existing network perfectly. Digital diagnostics make troubleshooting much easier, especially when checking transmit and receive optical power remotely. We've now deployed more than 60 modules across multiple sites and haven't experienced a single hardware failure. Highly recommended for long-distance Gigabit fiber deployments.
