Dual Fiber 4 Channels CWDM Mux Demux 1350 to 1410nm Low PDL Polarization Dependent Loss for Optimal Performance

Dual Fiber 4-Channel CWDM Mux/Demux (1350-1410nm) with Ultra-Low PDL


Premium Performance Optical Multiplexing Solution

Our Dual Fiber 4-Channel CWDM Mux/Demux delivers exceptional wavelength division multiplexing performance across the 1350-1410nm spectrum. Engineered for network efficiency, this compact module features:

* Ultra-Low PDL (<0.2dB): Minimizes polarization-dependent loss for consistent signal quality

* 4-Channel Capacity: Supports simultaneous transmission of multiple signals

* Dual-Fiber Design: Enables bidirectional communication with superior reliability

* 1350-1410nm Range: Optimized for specific wavelength requirements

* Industrial-Grade Stability: -40°C to +85°C operating temperature range


Technical Highlights

Precision Optical Engineering:

* Insertion loss: ≤1.8dB

* Channel spacing: 20nm standard (customizable)

* 3dB bandwidth: ±6.5nm

* Directivity: >50dB

* Return loss: >45dB


Applications:

✔ Metropolitan area networks
✔ Fiber-to-the-x (FTTx) systems
✔ CATV networks
✔ Enterprise network expansion
✔ Mobile fronthaul/backhaul


This CWDM module is ROHS compliant and comes with optional 19" rack mount or LGX box packaging. Custom channel configurations available upon request.

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.
