RED BLUE MWDM
C-LIGHT RED BLUE MWDM is a medium wavelength division multiplexing technology based on red-blue band partitioning, dividing the spectrum into red bands (longer wavelengths, e.g., 1547–1561 nm) and blue bands (shorter wavelengths, e.g., 1530–1543.2 nm) to enable single-fiber bidirectional transmission or wavelength-specific management. Utilizing thin-film filtering for wavelength separation, it achieves low insertion loss and high isolation, optimizing fiber resource utilization while reducing deployment costs. This technology is suited for metropolitan and backbone networks, balancing transmission capacity and system complexity.

    RED BLUE MWDM is a medium wavelength division multiplexing solution that divides the optical spectrum into red and blue wavelength bands for efficient wavelength management over a shared fiber. Using thin-film filtering technology, it separates the 1547–1561nm RED band and 1530–1543nm BLUE band with low insertion loss and high isolation. The solution is suitable for metro and backbone networks that require single-fiber bidirectional transmission and efficient fiber resource utilization.

    Key Features of RED BLUE MWDM

    Red and Blue Band Partitioning

    The MWDM architecture divides the optical spectrum into RED and BLUE wavelength bands, enabling efficient wavelength separation for bidirectional optical transmission.

    Single-Fiber Bidirectional Transmission

    Different wavelength bands can be assigned to opposite transmission directions, allowing bidirectional communication over a shared optical fiber.

    Thin-Film Filtering

    Thin-film filter technology provides selective wavelength separation while supporting low insertion loss and high isolation between the RED and BLUE bands.

    Flexible Customization

    Pigtail, fiber length, package dimensions, and connector configurations can be customized according to specific network integration requirements.

    RED BLUE MWDM Wavelength Configurations

    CLMWDM-1*

    CLMWDM-1* uses 1547–1561nm as the RED band and 1530–1543nm as the BLUE band, with optional pigtail, length, dimension, and connector configurations.

    CLMWDM-2*

    CLMWDM-2* reverses the band assignment, using 1547–1561nm as the BLUE band and 1530–1543nm as the RED band for flexible wavelength planning.

    RED Band

    The RED band covers the longer wavelength range of approximately 1547–1561nm and can be assigned to one direction or wavelength group according to the network design.

    BLUE Band

    The BLUE band covers the shorter wavelength range of approximately 1530–1543nm and can be paired with the RED band for bidirectional fiber transmission.

    How RED BLUE MWDM Works

    Spectrum Division

    The optical spectrum is separated into RED and BLUE wavelength bands, creating two distinct wavelength groups within the MWDM system.

    Wavelength Separation

    Thin-film filters selectively pass or reject designated wavelengths so that the RED and BLUE bands can be routed according to the optical network architecture.

    Bidirectional Fiber Sharing

    One wavelength band can be assigned to one transmission direction and the other band to the reverse direction, allowing both directions to share a single fiber.

    Fiber Resource Optimization

    Using different wavelength bands for bidirectional transmission can reduce the need for separate fiber pairs and improve utilization of existing fiber infrastructure.

    RED BLUE MWDM Applications

    Metro Optical Networks

    RED BLUE MWDM can be deployed in metro networks where efficient fiber utilization and wavelength-based bidirectional transmission are required.

    Backbone Networks

    The wavelength-band architecture provides an option for backbone links that need to optimize existing fiber resources while maintaining separate optical transmission directions.

    Single-Fiber Bidirectional Links

    RED and BLUE bands can be assigned to opposite directions, providing a practical wavelength solution for bidirectional transmission over a single fiber.

    Wavelength-Specific Management

    The separated wavelength bands provide greater flexibility for optical network planning, channel assignment, and fiber resource management.

    RED BLUE MWDM vs. Conventional WDM

    Band-Based Wavelength Management

    RED BLUE MWDM divides wavelengths into two defined spectral bands, making it particularly suitable for applications requiring separation of transmission directions.

    Single-Fiber Architecture

    The RED/BLUE wavelength assignment can support bidirectional transmission over one fiber instead of requiring separate fibers for each direction.

    Efficient Fiber Utilization

    By assigning different wavelength bands to different transmission paths, MWDM can improve the utilization of existing fiber resources.

    Flexible Integration

    Optional pigtails, connectors, fiber lengths, and dimensions allow the MWDM component to be adapted to different optical network equipment and deployment environments.
