CWDM Optical Module Advantages

CWDM optical modules use CWDM technology, which can combine optical signals of different wavelengths through an external wavelength division multiplexer, and transmit them through a single fiber, thereby saving fiber resources. At the same time, the receiving end needs to use a wave decomposition multiplexer to decompose the complex optical signal.CWDM optical modules are usually widely used in CWDM systems at lower cost than DWDM optical modules . In a CWDM system, the CWDM optical module is inserted in the switch, and the CWDM optical module is connected to the CWDM demultiplexer or OADM optical add/drop multiplexer with jumpers.
The CWDM optical module successfully solves the problems in the optical fiber transmission network to play a huge role in the CWDM system. CWDM optical modules has 8 major advantages, which are summarized as follows:
1. “Transparent” transmission of data;
2. Super large capacity, making full use of the huge bandwidth resources of optical fiber;
3. Greatly save fiber resources and reduce construction costs;
4. High networking flexibility, economy and reliability;
5. It can be switched over all optical networks to realize long-distance non-electrical relay transmission;
6. Simplified laser module, thereby reducing the size of the equipment and saving room space;
7. Optical layer recovery is independent of business and rate, and can effectively protect data;
8. No semiconductor cooler and temperature control function are needed, so power consumption can be significantly reduced, which is only 12.5% of DWDM.
