DWDM - Dense WaveLength Division Multiplex

DWDM (Dense Wavelength Division Multiplexing) is the ability to combine a group of optical wavelengths with a single optical fiber for transmission. This is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, this technology multiplexes the tight spectral spacing of a single fiber carrier in a specified optical fiber in order to take advantage of the achievable transmission performance (for example, to minimize dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.

The relationship between the communication transmission network and the business has become increasingly complex under the situation of a substantial increase in business volume. The original TDM (optical fiber single-wave transmission and time division multiplexing) cannot meet the needs of new technologies. The highest rate of optical fiber single-wave transmission for commercial applications is 40Gbits/s, and it is expensive. TDM technology is difficult to adapt to complex networks and business relationships. The optical fiber multiwave transmission technology that uses pure optical devices for long-wave dispatch has broken the limit of the processing speed of electronic devices. Based on the SDH technology, the optical fiber transmission capacity has been greatly improved. The current commercial application rate of Dense Lightwave Multiplexing (DWDM) technology (DWDM) technology (also known as OTN technology) has reached 3.2 Tbits/s, which means that the communication network can be smoothly upgraded and evolved.
A key advantage of DWDM is that its protocol and transmission speed are irrelevant. The DWDM-based network can use IP, ATM, SONET/SDH, and Ethernet protocols to transmit data, and the processed data flow is between 100Mb/s and 2.5Gb/s. In this way, DWDM-based networks can transmit different types of data traffic at different speeds on a laser channel. From the point of view of QoS (Quality of Service), DWDM-based networks quickly respond to customer bandwidth requirements and protocol changes in a low-cost manner.
