CWDM and DWDM

Optical fiber has become the main platform for telecommunications networks. However, new cables are often very expensive to build, and it is convenient to use CWDM or DWDM technology, which can multiply the data transmission capacity of optical fiber.

Passive CWDM technology is very cost-effective and is suitable for data rates of 10 Gbit/s or less.

By exploiting specific wavelengths, active DWDM systems can multiply data rates to 1600 Gbit/s in a single fiber pair.
