What is a CWDM/DWDM multiplexer/demultiplexer?
May 20 , 2022
As we all know, WDM (Wavelength Division Multiplexing) is a technology that uses multiple lasers to send multiple lasers of different wavelengths on a single fiber at the same time. It can realize two-way communication on one fiber and increase network capacity. In a WDM system, a multiplexer is generally used at the transmitting end to multiplex several optical signals into a bundle of optical ca...

Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8
Oct 14 , 2022
At present, the main products of 400G transceivers are QSFP-DD, OSFP and CFP8. This article introduces: Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8 1: QSFP-DD provides maximum port density. This makes QSFP-DD more attractive than OSFP form factor modules and larger CFP8 modules. 2: The power consumption (the maximum power that the module can dissipate without damaging the interna...
