C-LIGHT CWDM MUX/DeMUX is a passive coarse wavelength division multiplexing solution designed to expand fiber network capacity by combining multiple optical wavelengths onto a single fiber and separating them at the receiving end. It supports up to 18 wavelengths with 20nm channel spacing across the 1270–1610nm range, making it suitable for medium- and short-haul transmission distances of less than 80km. With low power consumption, simplified deployment, and flexible form factors, CWDM MUX/DeMUX provides a practical solution for enterprise networks, data center aggregation, and 5G fronthaul.
CWDM technology supports up to 18 optical wavelengths, allowing multiple services to share a single fiber and increasing network capacity without adding new fiber infrastructure.
The 20nm wavelength spacing provides a practical CWDM architecture with simpler wavelength planning and less stringent thermal control requirements than dense wavelength systems.
The CWDM platform supports wavelengths across the 1270–1610nm range for flexible multi-channel optical transmission.
Single-fiber and dual-fiber configurations are available to match different network architectures and fiber resource requirements.
As a passive optical solution, CWDM MUX/DeMUX does not require an independent power supply, helping simplify deployment and reduce operational complexity.
1U rack, LGX, and ABS package options support installation in rack-mounted systems, modular chassis, and compact optical distribution environments.
4-channel configurations provide a compact option for networks requiring a limited number of wavelengths and moderate capacity expansion.
8-channel configurations provide additional wavelength capacity for enterprise interconnection, access networks, and data center aggregation.
16-channel configurations support higher-density wavelength deployment while maintaining the straightforward architecture of CWDM technology.
18-channel configurations utilize the full wavelength range of the platform and provide maximum channel capacity for suitable CWDM network applications.
Dual-fiber configurations use separate fibers for transmission and reception, providing a conventional architecture for bidirectional CWDM networks.
Single-fiber configurations support bidirectional transmission over one fiber, helping conserve fiber resources in suitable network designs.
LC, SC, and ST connector options are available to match different fiber infrastructure and installation requirements.
Selected configurations include a +1310nm expansion or monitoring option for additional optical network functions and future capacity planning.
CWDM uses wider 20nm channel spacing and supports up to 18 wavelengths across 1270–1610nm. It is particularly suitable for short- and medium-haul networks where cost, simplicity, and fiber capacity expansion are key considerations.
DWDM uses much narrower wavelength spacing and supports higher channel density, making it more suitable for high-capacity metro, backbone, and long-distance optical transport systems.
CWDM allows multiple optical services to share existing fiber resources, making it suitable for enterprise network interconnection and infrastructure expansion.
The passive architecture and flexible channel options provide an efficient way to aggregate multiple optical links where fiber resources are limited.
CWDM wavelength multiplexing can support multi-channel optical transport in 5G fronthaul networks while helping reduce fiber deployment requirements.
With transmission distances below 80km, CWDM is well suited to regional, campus, metro-access, and other short- to medium-distance fiber links.
Multiple wavelengths can share one fiber, allowing network operators to expand optical capacity without deploying additional fiber for every service.
The wider channel spacing and passive optical architecture provide a simpler and more economical alternative for suitable short- and medium-haul network applications.
4CH, 8CH, 16CH, and 18CH options, together with single-fiber and dual-fiber configurations, support different network capacity requirements.
C-LIGHT applies a three-step quality control process, with products undergoing initial testing, final testing, and factory inspection before delivery.
