2x GPON & XGS-PON Combiner Coexistence CEx WDM Module SC/UPC


2x GPON & XGS-PON Combiner Coexistence CEx WDM Module SC/UPC

LightOptics’s passive optical CoExistence Element (CEx) WDM modules support your migration to next-generation PON (XGS-PON or NG-PON2) services while controlling costs. Our portfolio of coexistence (CEx) modules are integrated into the network near the optical line terminal (OLT), enabling existing PON services to coexist with XGS-PON, NG-PON2, RF video, optical time domain reflectometer (OTDR), as well as other current and future technologies. The GPON port passband, 1290-1500nm, allows for future 25G/50G services. The purpose of an upgrade port is to be able to add services not already in use, i.e. XGS-PON, RF-Video, NG-PON2, OTDR.
