DWDM Technology (dense wavelength division multiplexing) can combine multiple optical wavelengths and transmit them with one optical fiber. This is a laser technology used to improve the bandwidth of the existing optical fiber backbone network. More specifically, the DWDM technology multiplexes the close spectral spacing of a single optical fiber carrier in a specified optical fibre to facilitate the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation), so that the total number of optical fibers required can be reduced under a given information transmission capacity.

The wavelength range of DWDM technology is 1525nm-1565nm (C-band) and 1570nm-1610nm (L-band). It is a small section taken from the CWDM wavelength range. The commonly used is 1525nm-1565nm (C-band). The wavelength interval of this band range is 0.8nm.

DWDM Working Principle

Dense Wavelength Division Multiplexing (DWDM) relies on the optical carriers and can transmit multiple electrical information at the same time. However, only one optical fiber can complete the optical fiber communication technology required by the system capacity expansion. It forms a transmitter through several optical signals with different wavelengths. After multiplexing, it starts transmission and enters the optical fiber amplifier. Then the optical signal is separated and demultiplexed and transmitted to their respective terminals for the reception. Because only one optical fiber can complete the needs of multiple virtual path transmissions, it can reduce many costs and make full use of resources. Therefore, compared with traditional systems, the dense wavelength division multiplexing system (DWDM system) has strong advantages. It can not only maximize the use of broadband but also continuously expand the capacity of the network and optimize the structure. The process is simple and clear, but also very flexible. It has great potential and space in the field of optical fiber communication.
