CCWDM Module

Model NO.
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.

Excellent Performance Parameters (WDM systems with low loss and high isolation)


Lower Insertion Loss

Lower insertion loss makes CCWDM devices have lower signal attenuation when used in WDMsystems,which reduces the power requirementfor signal transmitters.

High Isolation

The high isolation makes CCWDM device use in the WDM system to isolate the signals adequately when transmitting multiple signals, and effectively prevent the signal from being distorted due to the crosstalk between the signals.

Mature Production Process

HYC 6-port CCWDM device has a mature production process. The optical path is made by non-glue and semi-automatic condition packaging. It has stable and reliable performance. It supports the work in the harsh environment of -40 ~+85℃, 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.

Normal CWDM Fiber Stage Mode


Compliance with international standards

The CCWDM module of HYC conforms to RoHS, Satisfies TelcordiaGR-1209 and GR-1221.

  • RoHS
  • TelcordiaGR-1209-CORE
  • GR-1221-CORE

Compact Design

The CCWDM module of HYC adopts parallel optical path connection stage, which is different from the optical fiber connection stage of CWDM, which saves significant space. The package size of CCWDM module accounts for about 1/4 of CWDM.
