100Base-BX-D Single-Mode SFP transceiver (up to 20 km), Tx:1550 nm, Rx:1310 nm


div>The DEM-220T/220R 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 100Base-BX operation and physical compactness to deliver the speed, reliable long-distance data transfer, and deployment flexibility that today’s fiber networks require.
Ideal for Long Distance Application 
The DEM-220T/220R transceivers can be used to connect switches, servers and fiber modules on a campus or metropolitan area network (MAN). Providing up to 20 km of fiber cable distance, these highly integrated transceivers offer low jitter performance for advanced optical communication support without any performance degradation. 
Reliable Transmission 
The DEM-220T/220R transceivers combine transmitting and receiving signals onto one fiber strand using two wavelengths. These transceivers are used in pair. At one end, one transceiver uses one wavelength to transmit and a second wavelength to receive. At the other end, the other transceiver flips that relationship. 
Standard Compliance 
The DEM-220T/220R transceivers use standard simplex LC connectors for fiber cable connection. They conform to industry standards. Hot-swap capability allows network administrators to plug or unplug them from the SFP slots without having to turn off the power of the connected device.
