Dual Fiber Coexistence Element CEx Module for NG-PON2 access
networks
The Dual Fiber Coexistence Element CEx Module is A single WDM
device used to combine current G-PON FTTH services with emerging
XGS-PON and Next Generation NG-PON2 technologies. THe 5CH Dual
Fiber Coexistence Element CEx Module is designed for PON
coexistence of GPON, XGS-PON, OTDR, RF video and NG-PON2, multiplex
into single fiber during transmission from OLT to ONU.
Detail Wavelength of Channel:
- GPON : 1290-1330 & 1480-1500nm
- XGS-PON : 1260-1280 &1575-1580
- OTDR : 1625-1650nm
- RF Video : 1550-1560nm

Excellent Performance Parameters
Lower insertion loss
Lower insertion loss makes GEZHI Dual Fiber Coexistence Element CEx
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 DWDM insert-box module,
effectively preventing crosstalk between signals and causing
distortion of the transmission signal.
