CEX WDM

T&S Cex-WDM is a kind of coexistence WDM product, which is mainly used in optical fiber access network. It can use EPON/GPON network of 1 to 2.5Gbps and XG-PON network of 10Gbps rate in the same ODN. , And even use NG-PON2 network with a rate of 10 to 40Gbps; using Cex-WDM can save a lot of ODN capital investment at the access network level.

Features of Cex WDM

Automatic Optical alignment

Bi-directional

Optical path epoxy free

Low insertion loss & high Isolation;

Thin Film Filter Technology

RoHS compliant

Applications of Cex WDM

T&S’ CEx-wdm Series is designed for Next Generation Passive Optical Networks (NG-PON), a new optical access system that coexists with GPON on the same ODN. Our CEx-wdm Modules, including GPON, XG-PON, NG-PON2 and OTDR, are designed to accommodate NG-PON1 and NG-PON2 TWDM wavelengths to maximize the density and enhance the speed of optical distribution network.
