High-Performance TFF Type CWDM Module for Telecom Networks
High-Performance TFF Type CWDM Module with Low Insertion Loss and High Channel Isolation for Telecom Networks
The TFF type CWDM module utilizes thin film filter technology to achieve multiplexing and demultiplexing of multi-wavelength signals through precise optical design. This solution supports efficient wavelength division multiplexing, enabling simultaneous transmission of multiple coarse wavelength division channels (typically 18 wavelengths spaced 20nm apart) in a single optical fiber to significantly improve fiber utilization.
Key Advantages
- Low insertion loss (typical value ≤ 1.5dB) with high channel isolation (≥ 30dB)
- Excellent temperature stability (wavelength drift ≤ 0.05nm within -5℃ to +70℃ range)
- Effective suppression of crosstalk between adjacent channels
- Ideal for medium to short distance transmission scenarios including urban area network access and enterprise private networks
Technical Specifications
| Parameter | Specification |
|---|---|
| Working wavelength range | 1270nm~1610nm (covering 18 ITU-T standard wavelengths) |
| Channel spacing | 20nm |
| Insertion loss | ≤ 1.5dB (typical value ≤ 1.2dB) |
| Channel isolation degree | ≥ 30dB (adjacent channel) |
| Polarization related loss | ≤0.1dB |
| Return loss | ≥45dB |
| Temperature stability | Center wavelength drift ≤ 0.05nm within -5℃~+70℃ range |
| Fiber type | SMF-28e+ single-mode fiber with FC/APC or SC/APC connectors |
| Dimensions | 120mm x 80mm x 15mm (standard module) |
| Operating Humidity | 5%~95% non-condensing |
Ultra-Low Loss Version for Long-Distance Transmission
The ultra-low loss TFF type CWDM module features insertion loss ≤ 1.0dB (typical ≤ 0.8dB) through optimized optical coating and structural design. This extends signal transmission distance while reducing relay devices and system deployment costs. The module maintains stable performance across wide temperature ranges (-5℃~+70℃) and is ideal for urban backbone networks and data center interconnection.
High-Density Compact Design
The compact version measures just 80mm × 50mm × 10mm (40% smaller than standard modules), enabling high-density deployment in 1U racks. This space-saving design is perfect for data center cabinets, fiber distribution frames, 5G fronthaul, and enterprise network expansion scenarios.
Telecom & Data Center Compatibility
Designed for telecom operators and data centers, this module supports flexible channel configurations (4/8/16 wave options) and features:
- High reliability (MTBF ≥ 100,000 hours)
- Low power consumption (≤ 2W/module)
- Hot-swappable interfaces (LC/SC compatible)
- Ruggedized design passing vibration, impact, and EMC tests
- Plug-and-play deployment for telecom metro networks, DCI, and enterprise networks
