C
Coarse
Wavelength
Division
Multiplexing
(CWDM)
CWDM is an optical signal transmission technology
that multiplexes coarsely-spaced optical channels
into a single optical fiber. Wavelength intervals are
wide, typically several nanometers or larger. It does
not support optical amplifiers. It is mainly used in
short distance chain networks.
D
Dispersion
Compensation
Fiber (DCF)
DCF has inherent negative dispersion that can offset
the positive dispersion of transmission fibers, so as
to maintain the original shape of the signal pulse.
Dense
Wavelength
Division
Multiplex(DWD
M)
DWDM is an optical signal transmission technology
utilizing high bandwidth and low loss characteristics
of single-mode fibers. Multiple optical carrier
channels with specific wavelength spacing can be
combined and transmitted within a single optical
fiber.
