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.
