CCWDM Module
The CCWDM module of HYC is a wavelength division multiplexing technology based on TFF (thin film filter). It works in the same way as the CWDM module. The difference is that CCWDM adopts free space technology, Compared with the CWDM module, its package size is greatly reduced, and the insertion loss is lower and the consistency is better. It can replace CWDM products and be used in TC, enterprise network, PON network, CATV and other fields.

Lower Insertion Loss

Lower insertion loss makes CCWDM module have lower signal
attenuation in operation, thus reducing the power
requirement of signal transmitter.

High Isolation

The higher isolation value enables sufficient signal
isolation during multi-signal transmission in the
CCWDM module, effectively preventing crosstalk between
signals and causing distortion of the transmission signal.

Mature Production Process

The CCWDM module of HYC has mature production technology,
stable and reliable performance, supports the work in the
harsh environment of - 25~+70 ℃, and ensures the stable
transmission of signals.

Free Space Technology

The CCWDM module of HYC uses free space technology and uses an independent sealed space to transmit optical signals. It works in the same way as CWDM. It inputs (outputs) optical signals from COM, and then outputs (inputs) optical signals through TFF (thin film filter) at other ports.
