As 5G networks rapidly deploy, traditional optical fiber transmission solutions face challenges such as soaring bandwidth demand, increased deployment complexity, and high costs. The semi-active Open-WDM solution has emerged as an effective approach to address these issues. This solution combines the flexibility of active devices with the cost-efficiency of passive devices, providing crucial technical support for 5G network construction through the coordinated operation of the entire system.
1. MWDM Color Light Module
The MWDM (Multiplexing Wavelength Division Multiplexing) color light module is one of the core components of the semi-active Open-WDM solution. It aggregates multiple signals onto a single optical fiber, enabling efficient multi-channel transmission. MWDM color light modules feature tighter wavelength spacing, typically using 10nm channel spacing, which allows for higher fiber utilization and greater transmission capacity. Each wavelength can carry different data, enabling the network to achieve higher bandwidth and lower transmission latency under limited fiber resources.
2. Central Office Semi-Active WDM Equipment and Boards
Central office semi-active WDM equipment and boards are another critical part of this solution. These devices are located at the central office of the network and are responsible for amplifying, distributing, and managing optical signals. The advantage of a semi-active design is that it can reduce costs while still maintaining effective signal control. Through amplification and equalization by active equipment, the signal can remain stable and high-quality during long-distance transmission. Additionally, the modular design of the boards allows the system to be flexibly expanded according to demand, adapting to changes in different network scales and application scenarios.
3. Remote Passive Multiplexers/Demultiplexers
Remote passive multiplexers/demultiplexers are mainly used for the multiplexing and demultiplexing functions of optical signals. These passive devices do not require power, making them easier to maintain and operate, with lower operational costs. Passive multiplexers/demultiplexers utilize Thin-Film Filter (TFF) technology to precisely separate or combine optical signals of different wavelengths, ensuring transmission quality and stability. These devices are typically installed at remote sites and, through coordinated operation with central office equipment, achieve efficient signal management and distribution.
4. Management and Control System
To ensure the efficient operation of the entire semi-active Open-WDM solution, the management and control system plays a crucial role. This system ensures network stability and reliability through real-time monitoring of optical signals, fault detection, and network optimization. The management and control system also features automated operation and maintenance functions, automatically adjusting parameters based on network conditions, optimizing network performance, and reducing manual intervention and maintenance costs. This enables the entire network to not only meet current high bandwidth demands but also to handle future network expansion and upgrade needs through intelligent management.
