Upgrading your existing passive optical network (PON) enables increased data speed and the delivery of additional services without fully replacing existing PON infrastructure.

LightOptics’s passive optical devices 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, NG-PON2, OTDR.

LightOptics’s FTTx cassette CEx portfolio of solutions meet ISP requirements of -10°C to +65°C operating temperature environments, and our industrial standard LGX module CEx portfolio of solutions meet OSP requirements of -40°C to +70°C operating temperature environments,
The LGX CEx WDM modules are tested to IEC 61300-2-1, -9, -21, -22, -26 and GR-1209 requirements. FTTx cassette CEx products are tested to GR-63 requirements.

LightOptics uses high quality components that ensure very high operation stability of xWDM/xPON multiplexers in the wholespectral range and perfect thermal stability.
