The FET-6945 is a dedicated 7 port, Gigabit Ethernet switch. 3 Copper ports provide 1Gb/s connectivity for multiple Ethernet enabled devices or links to additional network switches. 3 optical ports provide Ethernet links over three, bi-directional fiber connections for extended distances. An additional port is available for the OG3 frame’s optional internal GigE controller.
The FET-6945 is available in 2 varieties: The FET-6945-20A/B transceiver pair is capable of running up to a 20km link between 2 transceivers. The FET-6945-40A/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 FET-6945 transceivers at each end of the link must complement each other in regards to their wavelength TX and RX.
