D-LINK DEM-310GT Transceiver Specifications (SFP, 1000BASE-LX)

Description:

The D-Link DEM-310GT module is an optical transceiver in SFP (Small Form-Factor Pluggable) format, designed for data transmission at speeds of up to 1.25 Gbps over single-mode fiber at distances up to 10 km. It comes in a metal housing to improve electromagnetic resistance and supports "hot-swappable" replacement without shutting down the equipment.
