The DEM-330R / DEM-330T 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.

The DEM-330R/10KM and DEM-330T/10KM transceivers are used in pair. The DEM-330R/3KM and DEM-330T/3KM transceivers are used in pair. 

 

The DEM-330R / DEM-330T transceivers can be used to connect switches, servers and fiber modules on a campus or metropolitan area network (MAN). Providing up to 3 km (DEM-330R/3KM and DEM-330T/3KM) or 10 km (DEM-330R/10KM and DEM-330T/10KM) of fiber cable distance, these highly integrated transceivers offer low jitter performance for advanced optical communication support without any performance degradation.

 

The DEM-330R / DEM-330T 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.

 

The DEM-330R / DEM-330T transceivers use standard simplex LC connectors for DEM-330R/10KM and DEM-330T/10KM or SC connector for DEM-330R/3KM and DEM-330T/3KM for fiber cable connection. They conform to industry standards and are interoperable with D-Link Gigabit switches. 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.
