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 ber 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 ber link. When using WDM single ber link,
the two FES-6941 transceivers at each end of the link must
complement each other in regards to their wavelength TX
and RX.
