Questions & Answers

Ask a Question
No data
  • Q: Will it work with OEM-compatible switches from different vendors? By E***s on 2026-04-24

    A: Yes. The module is designed for broad OEM compatibility. It has been widely deployed on various mainstream networking platforms. If you need a specific coding option, LINK-PP can usually provide compatible programming before shipment. By admin on 2026-04-24

  • Q: Can this 1G BiDi SFP really support a full 100km optical link? By S***t on 2026-04-01

    A: Yes. This module is designed for Gigabit Ethernet transmission over single-mode fiber up to 100km, provided the fiber quality and overall optical link budget meet the required specifications. By admin on 2026-04-01

  • Q: What module should I use on the opposite end of the fiber? By E***r on 2025-07-16

    A: This model transmits at 1490nm and receives at 1550nm. It must be paired with the complementary BiDi transceiver that transmits at 1550nm and receives at 1490nm (such as LS-BL55491G-A0C)to establish a working fiber link. By admin on 2025-07-17

  • Q: Does this module support DOM or DDM monitoring? By B***h on 2025-06-08

    A: Yes. It supports Digital Optical Monitoring (DOM/DDM), allowing you to monitor transmit power, receive power, temperature, voltage, and laser bias current in real time. By admin on 2025-06-08
