What Are The Advantages Of The CWDM Multiplexer System?
Dec 28, 2018

CWDM is a low-cost WDM transmission technology for the access layer of the metropolitan area network. In principle, CWDM uses an optical multiplexer to multiplex optical signals of different wavelengths into a single optical fiber for transmission. At the receiving end of the link, the mixed signal in the optical fiber is decomposed into different wavelengths by means of an optical demultiplexer. Signal, connected to the corresponding receiving device.

1. The CWDM system can significantly improve the transmission capacity of optical fibers and improve the utilization of optical fiber resources.

2. Another advantage of CWDM is its small size and low power consumption.

3. The simplified laser module in the CWDM system reduces the volume of the optical transceiver integrated module, and the simplification of the device structure also reduces the size of the device and saves room space.

4. Another advantage of CWDM is that it can reduce the operating costs of the network. Because CWDM equipment is small in size, low in power consumption, easy to maintain, and convenient in power supply, 220V AC power can be used.

5. Since the number of wavelengths is small, the amount of board backup is small.
