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...

Passive wavelength division optical transmission solution--CWDM/DWDM
Dec 17 , 2021
In the construction of optical transmission networks, long-distance transmission needs to consume a lot of optical fiber resources. WDM passive components can multiplex multiple optical signals into one optical fiber, expand transmission capacity and save optical fiber resources. Among them, CWDM and DWDM devices are two of the more commonly used devices. Equipped with corresponding color light mo...
