FET-6946 Triple Link Ethernet Fiber Transceiver (WDM & Dual Fiber)

The FET-6946 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. 2 optical ports provide 2 Ethernet links over two, bi-directional fiber connections and 2 additional optical ports provide a 3rd Ethernet link over dual fiber connections. An additional port is available for the OG3 frame’s optional internal GigE controller.

The FET-6946 is available in 2 varieties: The FET-6946-20A/B transceiver pair is capable of running up to a 20km link between 2 transceivers. The FET-6946-40A/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-6946 transceivers at each end of the link must complement each other in regards to their wavelength TX and RX.
