D-Link DEM-331T Gigabit WDM Single-Mode 40KM SFP Transceiver (TX-1550/RX-1310 nm)

Part Number: DEM-331T

The DEM-330T/330R and DEM-331T/331R Bidirectional Gigabit SFP Fiber Transceivers are external transceivers designed for insertion in SFP (Small Form-Factor Pluggable) slots of network devices 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.
