Optical Add/Drop Multiplexer (OADM)
The optical add/drop multiplexer module provides the ability to add or drop a single wavelength or multi-wavelengths
from a fully multiplexed optical signal. This allows intermediate locations between remote sites to access the common,
point-to-point fiber segment linking them. Wavelengths that are not dropped pass through the OADM and continue in
the direction of the remote site. See Figure 12.

CWDM Wavelength-specific Optical Transceivers
Lantronix full line of media converters and switches can incorporate CWDM wavelengths with the addition
of wavelength-specific small form-factor pluggable (SFP) optical transceivers or traditional fixed optical ports. CWDM
standard and are available for Fast Ethernet, Gigabit Ethernet, OC-3/STM-1,
OC-12/STM-4, and OC-48/STM-16 data rates. Fixed optical ports are available in Fast Ethernet and Gigabit Ethernet,
and in the same CWDM ITU wavelengths.
