0231A11U H3C Compatible 1G SFP BiDi 10km SMF Transceiver

The 0231A11U is a 1G BiDi SFP that carries Gigabit Ethernet up to 10km over a single strand of single-mode fiber. As the BX-D (downstream) half of a BiDi pair, it terminates one end of the link through a simplex LC connector, letting a single fiber do the work of two. It coded to bring the port up on H3C switching hardware and reports live optical readings over DDM, so power and temperature can be polled from the host CLI.

• Form Factor: SFP
