1×64 PLC + WDM Integrated Module: A Compact Solution for CATV Overlay in PON Networks
Introduction
As fiber access networks continue to expand, operators are facing increasing challenges in rack space utilization, fiber management, and deployment efficiency.
Traditional CATV overlay solutions on PON networks typically use separate FWDM devices, PLC splitters, and additional fiber patching structures. While this approach is flexible, it increases installation complexity and requires more rack space.
To address these challenges, Feiyi Optoelectronic developed a 1×64 PLC + WDM Integrated Module, combining signal separation and optical splitting functions into a single 1U rack-mounted solution.
Integrated Design for Simplified Deployment
The module integrates three key optical functions:
1. FWDM Signal Separation
The integrated FWDM separates:
- 1550nm CATV downstream signals
- 1310/1490nm IP data signals
This enables CATV overlay transmission over existing PON fiber infrastructure without additional fiber routes.
2. 1×64 PLC Splitting
The built-in PLC splitter provides:
- 1×64 optical splitting capability
- Low insertion loss on IP path
- Stable performance for high-density FTTx deployments
The COM to IP output path insertion loss is ≤0.8dB.
3. MPO/APC High-Density Interface
The MPO/APC output design helps:
- Reduce fiber patching complexity
- Improve installation efficiency
- Support high-density network environments
Key Performance Specifications
- Operating wavelength: 1260–1620nm
- CATV wavelength: 1539–1565nm
- IP wavelength: 1270–1350nm / 1480–1505nm / 1580–1620nm
- Isolation: ≥45dB
- Return loss: ≥45dB
- Connector: LC/APC + MPO/APC
- Rack format: 19-inch 1U
The module is designed according to Telcordia GR-1209 and GR-1221 reliability requirements.
Advantages Compared with Traditional Solutions
Compared with separate FWDM + PLC + patching structures, the integrated design provides:
- Reduced installation complexity
- Better rack space utilization
- Fewer fiber connection points
- Easier maintenance and management
Applications
The 1×64 PLC + WDM Integrated Module is suitable for:
- FTTH networks
- CATV overlay systems
- PON access networks
- High-density optical distribution environments
Conclusion
As operators continue to upgrade fiber infrastructure, integrated optical solutions provide a more efficient approach to network deployment.
By combining WDM signal management and PLC splitting in a compact 1U platform, the 1×64 PLC + WDM module helps simplify FTTx deployment while improving scalability and reliability.
