D-LINK 1000Base-BX-D Single-Mode WDM SFP transceiver DEM-331T

The DEM-331T bidirectional SFP fiber transceivers are external transceivers designed for insertion in SFP (Small Form-Factor Pluggable) slot of network device for transmission and reception of data signals on the fiber cables. These transceivers provide the Gigabit operation and physical compactness to deliver the speed, reliable long-distance data transfer, and deployment flexibility that today’s fiber networks require.
