Multiplexer applications

Use OADMs to add and drop wavelengths to and from an optical fiber. Use multiplexers to
combine up to eight wavelengths on a single fiber. This section describes common applications
for the OADM and OMUX.

OADM ring
The OADM removes (or adds) a specific wavelength from an optical ring and passes it to (or
from) a GBIC or SFP of the same wavelength, leaving all other wavelengths on the ring
undisturbed. OADMs are set to one of eight supported wavelengths.
Important:
The wavelength of the OADM and the corresponding GBIC or SFP must match.
The following figure shows an example of two separate fiber paths in a ring configuration
traveling in opposite (east/west) directions into the network.
