This 1000BASE-LX/LH SFP uses a 1310nm wavelength and supports Digital Optical Monitoring (DOM), so you can monitor transmit and receive optical levels. It is designed for reliable long-term network use and operates in extended temperatures from -5°C to 85°C.

Installation is simple: insert the hot-swappable GLC-LH-SMD into an open Gigabit SFP port, connect your dual LC fiber cable, and verify link status. For legacy multimode fiber, use a mode conditioning patch cable to help ensure a stable connection.
