Application of WDM (passive wavelength division multiplexer) in 5G fronthaul
Oct 25 , 2022
Passive wavelength division multiplexer (WDM) designed to address fiber resources for long-haul transmission between distributed units (DUs) and active antenna units (AAUs) in Centralized Radio Access Network (C-RAN) 5G fronthaul architectures In addition, passive WDM can save fiber resources. In passive WDM, color optical modules are directly deployed on AAUs and DUs, and multiple AAUs can share ...

10G SFP+ Optical Module Features Introduction - FIBERWDM
Nov 04 , 2022
In recent years, thanks to the accelerated development of broadband networks, the application of 10G networks has become increasingly widespread. Regarding the 10G SFP+ optical module (the basic transmission equipment of the 10G network), the parameters we need to know are as follows: 1. Center wavelength (nm): There are three main types: 1) 850nm (multimode, low cost but short transmission distan...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Nov 15 , 2022
The technology of simultaneously transmitting information of two or more optical wavelength signals through different optical channels in the same fiber is called wavelength division multiplexing (WDM). WDM (Wavelength Division Multiplexing) is to combine two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end through a multiplexer, and c...

How to troubleshoot and solve fiber optic transceivers?
Dec 22 , 2022
The use of fiber optic transceivers is very simple. When applying fiber optic transceivers to the network, if they cannot work normally, troubleshooting is required. The following six aspects can be used to troubleshoot and solve: 1. The power indicator light is off, and the fiber optic transceiver cannot communicate. Solution: a. Confirm whether the power cord is connected to the power connector ...

Explanation of relevant knowledge points of WDM network
Dec 27 , 2022
A WDM network is a network that deploys optical WDM fiber links, where each link carries multiple wavelength channels. WDM, an acronym for Wavelength Division Multiplexing, is a technology that multiplexes multiple signals on a single optical fiber by using optical carriers of different wavelengths using lasers or LEDs. There is a multiplexer and a demultiplexer at each end of the WDM. A multiplex...
