FES-6941 Single Link Ethernet Fiber Transceiver (WDM)


Single Link Ethernet Fiber Transceiver (WDM)

6 Port, Gigabit Ethernet switch with single link, bi-directional fiber transceiver.

Ordering information

The FES-6941 is a dedicated 6 port, Gigabit Ethernet switch. 4 Copper ports provide 1Gb/s connectivity for multiple Ethernet enabled devices or links to additional network switches. 1 optical port provides an Ethernet link over a single, bi-directional fiber connection for extended distances. An additional port is available for the OG3 frame’s optional internal GigE controller.

The FES-6941 is available in 2 varieties: The FES-6941-20A/B transceiver pair is capable of running up to a 20km link between 2 transceivers. The FES-6941-40A/B transceiver pair is capable of running up to 40km link, by using a higher output power and higher receiver sensitivity SFP.

Using WDM (Wave Division Multiplexing), a bi-directional link can be obtained using 1310nm and 1550nm wavelengths over a single fiber link. When using WDM single fiber link, the two FES-6941 transceivers at each end of the link must complement each other in regards to their wavelength TX and RX.
