Low Insertion Loss Filter WDM Module for GPON/XGS-PON Networks
Product Overview
Our CEX WDM series is engineered for next-generation passive optical networks (NGPON), designed to coexist with GPON on the same optical distribution network. These advanced WDM devices integrate GPON, XGS-PON, RF video, and OTDR combiners to support NGPON1 and NGPON2 TWDM wavelengths, maximizing network density and enhancing transmission speeds.
Key Features
- Low insertion loss for optimal signal integrity
- Low polarization dependent loss (PDL)
- High channel isolation for minimal interference
- Excellent environmental reliability and stability
Applications
WDM systems and CATV networks
