CCWDM MUX / DEMUX

CCWDM is a wavelength-division multiplexing technology based on TFF (thin-film filters). Its operating principle is similar to CWDM, but it uses free-space technology. This significantly reduces module size, lowers insertion loss, and improves channel consistency. CCWDM can be used as a compact alternative to conventional CWDM modules.

Features

• Low insertion loss. Reduced insertion loss improves CCWDM module performance.
• High isolation. Higher isolation ensures adequate separation of multiple channels in the CCWDM module, reducing crosstalk and signal distortion.
• Mature manufacturing process. The CCWDM module uses a mature manufacturing process, provides stable and reliable operation, supports harsh environments from -25 to +70℃, and maintains stable signal transmission.

Free-Space Technology.
The CCWDM module uses an independent sealed free-space optical path. The optical signal enters through the COM port, passes through TFFs (thin-film filters), and is distributed among the corresponding channels; in the reverse direction, the channels are combined.

Conventional CWDM	CCWDM Free-Space Technology.

The free-space CCWDM design makes it easy to integrate performance monitoring.

Compact design.
The CCWDM module uses a parallel optical-path structure instead of the cascaded fiber connections typical of conventional CWDM. This significantly reduces size: a CCWDM module is approximately one quarter the size of a conventional CWDM module.

Applications.
The CCWDM module offers low insertion loss, high channel isolation, stable operation under different environmental conditions, and a compact free-space design. It can be used as a compact alternative to conventional CWDM modules.

NOTE!
An UPG expansion port makes it easy to cascade multiplexers.
Example: 8 channels (1310 ~ 1450) + UPG port and 8 channels (1470 ~ 1610) + UPG port = a complete 16CH MUX.
