Related working principle and applications of Tunable DWDM transceiver
Sep 07 , 2021
DWDM is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified optical fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, With a given information t...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Sep 26 , 2021
What are the performance indicators that affect the WDM wavelength division multiplexer? 1. Working band The working band of WDM devices, such as 1550 wavelength, is divided into three bands: S band (short wavelength band 1460～1528nm), C band (conventional band 1530～1565nm), L band (long wavelength band 1565～1625nm). 2. Number of channels and channel spacing The number of channels refers to the nu...
