The Free Space CCWDM 18 channels Compact CWDM Mux/Demux Module

Product Overview

Description

      18-CH COMPACT CWDM MUX/DEMUX MODULE (18CH CCWDM)

The Free Space CCWDM--18 channels Compact CWDM Mux/Demux Module

 

        3C-LINK’s compact size Coarse Wavelength Division Multiplexers (Mini CWDM, Compact CWDM, CCWDM), are integrated optical modules using 3C-LINK’s proprietary optical bench platform which can significantly improve optical performance, while also reduce manufacturing cost. Compare to the common standard CWDM module, 3C-LINK’s Mini CWDM takes much smaller package size. Much space can be saved in the application and meanwhile the performance and parameters are also better. All 3C-LINK’s CWDM modules are Telcordia qualified.(Meet TELCORDIA GR-1221-CORE)

 

 

Free Space Technolog

        The CCWDM module of 3C-LINK 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.

 

 

Typical Spectrum

 

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.
