The C-LIGHT CLCWMUX4CHD is a 4-channel dual-fiber CWDM (Coarse Wavelength Division Multiplexing) module designed for high-density fiber optic networks. It supports flexible deployment in 1U rack, LGX box, or ABS housing. Utilizing CWDM technology, this module enables efficient multi-wavelength signal transmission over a single fiber, significantly reducing network complexity and costs. Its unique 1310nm EXP./MON. port further enhances network operation flexibility and manageability.
●Core Technical Advantages
Dual-Fiber Architecture & Multi-Wavelength Support
Dual-Fiber Design: Enables bidirectional transmission, minimizing physical link complexity for metro area networks (MAN) and data center interconnects (DCI).
4-Channel Configuration: Covers ITU-T standard wavelengths (e.g., 1470nm, 1490nm, 1510nm, 1530nm), boosting single-module capacity to 4×10G/25G.
●Universal Connector Compatibility
Supports LC/SC/ST interfaces, ensuring seamless integration with existing network infrastructure and avoiding upgrade costs.
Flexible Deployment & Scalability
Modular Design: Choose from 1U rack, LGX, or ABS housing to meet diverse deployment needs in data centers, telecom rooms, and enterprise networks.
High Reliability
Low insertion loss (<2.5db) and="" high="" isolation="">30dB) ensure stable long-distance transmission.
Industrial temperature range (-40°C to +85°C) suits harsh environments.
●Key Application Scenarios
5G Fronthaul Networks
Delivers cost-effective, high-bandwidth transmission between base stations (AAU) and core networks, meeting 5G low-latency requirements.
Data Center Interconnect (DCI)
Expands capacity over limited fiber resources, supporting 10G/25G cross-data-center traffic.
Enterprise WAN
Simplifies branch network architecture with dual-fiber parallel transmission for video, voice, and data services.
Fiber Resource Optimization
Reuses legacy fiber infrastructure to avoid redundant cabling, reducing CAPEX.
●Why Choose C-LIGHT 4 Channel CWDM MUX?
Standardization & Compatibility
Compliant with ITU-T G.694.2 standards, interoperable with mainstream CWDM modules
Cost Efficiency
Reduces deployment costs by over 50% compared to DWDM systems, eliminating the need for cooled lasers.
Operational Simplicity
Hot-swappable modular design minimizes network downtime.
●Installation & Maintenance
Installation Tips:
Avoid excessive fiber bending (bend radius >30mm) to prevent signal attenuation.
Regularly clean connector end faces to maintain low insertion loss.
Monitoring Configuration:
Connect OTDR or optical power meters via the 1310nm port for real-time link performance analysis.
