CWDM modules (Coarse Wave Division Multiplexing) combine or split up to 16 wavelengths into a single fiber. CWDM technology uses an ITU standard 20nm spacing between the wavelengths, from 1310nm to 1610nm.
CWDM Modules utilize thin-film coating and micro optics package technology. CWDM modules are available in two main configurations: CWDM Multiplexer/Demultiplexer (Mux/Demux) modules and CWDM Add/Drop Multiplexer (OADM) modules.
CWDM Mux/Demux Modules are available in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 or more electronic devices, send them over a single optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices at the other end of the fiber optic link.
CWDM Add/Drop multiplexer modules provide 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 not dropped, pass-through the OADM and continue on in the direction of the remote site. Additional selected wavelengths can be added or dropped by successive OADMS as needed.
CWDM Add/Drop multiplexer Unit allows a single channel (CWDM Wavelength) to be inserted/extracted from the composite CWDM trunk. There are two versions of the OADM, one does Add/Drop in both directions, the second does Add/Drop in a single direction.
We provide CWDM module with various kinds of connectors and cable length and optional stainless tube package or standard box package and to meet your requirement. We offer 1x2 CWDM Module, 1x3 CWDM module, 1x4 CWDM Module, 1x5 CWDM Module, 1x6 CWDM Module, 1x7 CWDM Module, 1x8 CWDM Module, 1x9 CDWM Module ...up to 1x16 CWDM Module. Our CWDM modules are configured by number of channels for any customer-specify channel plan, and can be integrated with taps and detectors for a complete CWDM solution. ...Specification
