1x4 CH Optical CCWDM Mux / Demux Module in Passive Optical Network
GEZHI Photonics CCWDMs. Compact coarse wavelength division multiplexers, or CCWDMs, are integrated optical modules that are designed to significantly improve optical performance, while reducing manufacturing costs, in a package less than 1/4 the size of conventional CWDM modules.
Our CCWDMs feature high wavelength accuracy and stability, low insertion loss, high isolation, low polarization dependent loss and an epoxy-free optical path. Our Telcordia 1209/1221-qualified CCWDM builds on GEZHI Photonics' proprietary optical bench platform, and we believe it has the smallest footprint of any comparable CWDMs. With a channel spacing of 20 nm and wide bandpass characteristics, it allows for datacom or telecom network applications with low-cost uncooled lasers. These CCWDM Mux/Demuxes are available in four or eight channels and include an expansion port for 16 channel systems.

CWDM Compare CCWDM
It is worth noting that although the CWDM technology is not very popular for a long time, but by the time the seal was CWDM demand, developers have "upgraded" technology to create multiplexers.
In contrast to the "old" proven cascading CWDM filter technology, advanced CWDM multiplexers manufactured by planar technology.
This technology involves the creation of a complex planar waveguide, which is complemented by thin-film filters and collimators. multiplexing devices made using this technology are called CCWDM multiplexers (CompactCWDM).
Above picture is an interior structure of CWDM multiplexers. On the left - a classic on the basis of the multiplexer CWDM filter stage, right - CCWDM multiplexer.
CCWDM multiplexers on top were not popular in the first place due to their size - a little bigger than a matchbox.
Engineers internet service providers are wary of such a small device, which, moreover, it was difficult to fix in a standard patch panel.
