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
