shows an example of two separate fiber paths in a ring configuration
traveling in opposite or east/west directions into the network.

Optical multiplexer/demultiplexer description
The passive CWDM OMUX sends and receives signals to/from CWDM GBIC
transceivers installed in the switch. It multiplexes and demultiplexes four or eight
CWDM wavelengths from a two-fiber (east and west) circuit. It allows you to
create uni-directional network traffic rings or point-to-point links.
The CWDM OMUX (
Figure 6
) is installed in a 19-inch, rack-mounted 1RU
optical shelf (
Figure 15
).
