Questions & Answers

Ask a Question
No data
  • Q: Does it support DOM diagnostics for monitoring? By C***s on 2026-05-13

    A: Yes. The module supports Digital Optical Monitoring (DOM/DDM), allowing supported switches to monitor transmit power, receive power, module temperature, supply voltage, and laser bias current for easier network maintenance. By admin on 2026-05-13

  • Q: Do I need two fibers to use this transceiver? By K***e on 2026-01-01

    A: No. This is a BiDi SFP module that uses a single simplex LC connector over single-mode fiber. It transmits at 1490nm and receives at 1550nm, and must be paired with the complementary 1550nm TX / 1490nm RX module. By admin on 2026-01-01

  • Q: Will this module work with Cisco and other OEM switches? By R***l on 2025-04-22

    A: Yes. The module is designed for broad OEM compatibility and is widely deployed with Cisco-compatible switches as well as many other major networking brands. Please verify compatibility with your specific switch model before ordering. By admin on 2025-04-23

We replaced branded 1000BASE-BX optics with this model during a network expansion. The 1490nm transmitter and 1550nm receiver matched our existing BiDi deployment perfectly. Optical power, temperature, and voltage reported through DOM all remained within expected ranges after continuous traffic testing. Considering the price difference compared with OEM optics, this has been an excellent investment for our enterprise network.

We selected this 1.25Gbps BiDi optical transceiver for a regional warehouse project where fiber resources were limited. Using a single fiber instead of two significantly reduced installation costs. Compatibility testing covered Cisco Catalyst, MikroTik CRS, and several unmanaged Gigabit switches with excellent results. If you're searching for a reliable 1G BiDi SFP 60km with DOM support, this module is definitely worth considering. :)

Our IT team deployed more than forty units across multiple campus locations using existing simplex LC single-mode fiber. Installation required no additional configuration, and every module established a stable Gigabit Ethernet connection immediately. We monitored transmit power and receive power through DDM during burn-in testing, and all values remained consistent. The modules have performed reliably for daily business traffic and remote office connectivity.
