Description

Ultra Low PDL Dual Fiber 4 Channels CWDM Mux Demux 1370-1530nm for Bidirectional Communication and Optimal Performance

Enabling Bidirectional Communication with Industry-Leading Performance

Key Features:

* 4-channel CWDM technology with 1370/1390/1410/1530nm wavelength configuration

* Ultra-low PDL (<0.2dB) ensures minimal signal distortion for data integrity

* Dual-fiber design supports simultaneous bidirectional transmission

* Compact LGX box packaging with SC/LC connector options

* -40℃~+75℃ operating temperature range


Technical Advantages:
✓ 0.8dB max insertion loss for optimal signal quality
✓ >30dB channel isolation prevents crosstalk
✓ 100Gbps aggregate capacity per fiber pair
✓ Telcordia GR-1209/1221 compliant reliability


Application Scenarios:
* Metro access networks
* 5G fronthaul/backhaul systems
* Enterprise dual-fiber ring architectures
* Data center interconnect (DCI) solutions


This professional-grade 4-channel CWDM mux demux module delivers ultra-low polarization dependent loss (PDL) performance for demanding bidirectional communication systems. Engineered for 1370-1530nm wavelength range, our dual-fiber CWDM solution provides 4 independent optical channels in single 1U rack space, reducing fiber count by 75% while maintaining <0.5dB ripple uniformity.

The hermetic sealed design ensures stable operation in harsh environments, making it ideal for FTTx deployments and mobile transport networks. With industry-leading >40dB return loss, this CWDM mux demux set significantly outperforms conventional WDM devices in OSNR-sensitive applications.


Package Includes:

1× 4CH CWDM Mux

1× 4CH CWDM Demux

2× Dust caps

Installation guide


Why Choose Our CWDM Solution?
→ Plug-and-play deployment with <15min commissioning time
→ 3-year warranty with lifetime technical support
→ RoHS/REACH compliant eco-friendly manufacturing

CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm. Our CWDM module has 2 to 18 channels. The central wavelength of each channel is specified to one of the ITU-T grid wavelengths. The CWDM module features wide channel bandwidth (13nm). Its isolation is greater than 30dB for adjacent channels, and greater than 40dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment.
