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
ber 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 ber link. When using WDM single ber link, the two
FET-6945 transceivers at each end of the link must complement
each other in regards to their wavelength TX and RX.
