The FED-6943 is a dedicated 7 port, Gigabit Ethernet switch.
4 Copper ports provide 1Gb/s connectivity for multiple Ethernet
enabled devices or links to additional network switches. 2
optical ports provide Ethernet links over two, bi-directional
ber connections for extended distances. An additional port is
available for the OG3 frame’s optional internal GigE controller.
The FED-6943 is available in 2 varieties: The FED-6943-20A/B
transceiver pair is capable of running up to a 20km link between
2 transceivers. The FED-6943-40A/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 FED-6943 transceivers at each end of the link must
complement each other in regards to their wavelength TX
and RX.
