wavelength resources more efficiently than CWDM modules. DWDM and CWDM
modules allow lights with different center wavelengths to be transmitted on one
fiber without interfering each other. Therefore, a passive multiplexer can be used
to combine the lights into one channel, which is then split into multiple channels
by a demultiplexer on the remote end. This reduces the optical fibers required.
DWDM and CWDM modules are used for long-distance transmission.
The transmit power of a long-distance optical module is often larger than its
overload power. Therefore, when using such optical modules, select optical fibers
of an appropriate length to ensure that the actual receive power is smaller than
the overload power. If the optical fibers connected to a long-distance optical
module are too short, use an optical attenuator to reduce the receive power on
the remote optical module. Otherwise, the remote optical module may be burnt.
