CWDM Optical MUX / DEMUX
Three sets of MUX / DEMUX modules are available: a 4 channel with expansion port, an 8 channel, and an 8
channel with expansion port. Using individual, or a combination of modules, allow for the creation of 4, 8, 12,
or 16 channel systems. Modules with expansion ports enable the use of existing non-CWDM 1310nm lasers
to create 5, 9 and 13 channel systems.
Wavelength MUX / DEMUX modules use passive wavelength lters. The modules t the DFR-8321 frame
but draw no power. With no active components, modules offer a very high level of reliability.
CWDM Transmitters and Receivers
Wave division multiplexing allows the use of multiple wavelengths of light on a single ber, therefore allowing
a single ber to carry multiple signals. Each signal can run at its own bit rate and protocol, independent for
the other signals.
Each electrical signal to be multiplexed into the nal output must be converted to an optical signal with
a unique wavelength by using different lasers on the transmitter. The FDT-6604 dual electrical to optical
transmitter comes in 8 product variants, utilizing DFB optical SFPs, with each card transmitting
two neighboring wavelengths. The products are identied by a two digit sufx, which identies the
lower wavelength.
Optical to electrical converters use a wide spectrum optical receiver, and will work with any wavelength. Both
the FSR-6601 single and the FDR-6603 dual optical to electrical converters are wide spectrum receivers and
will function within a CWDM system, regardless of the transmitted wavelengths.
