What is a Wavelength Division Multiplexer (WDM)?
Jun 25 , 2021
Wavelength Division Multiplexer (WDM) is a technology that simultaneously transmits multi-wavelength optical signals on a single optical fiber. The wavelengths of the digital signals carried by these optical signals can be at the same rate and in the same data format, or at different rates and in different data formats. By adding new wavelength characteristics, the network capacity is determined a...

DWDM Multiplexer And Demultiplexer is A Wise Choice
Jul 23 , 2021
The emergence of big data requires efficient and capable data transmission speed. In order to solve the paradox of increasing bandwidth and spending less, multiplexers/demultiplexers are the best choice. This technology can transmit very large data traffic in the telecommunications network. This is a good way to deal with the bandwidth explosion from the network. Wavelength division multiplexing W...

Specific steps for SFP transceiver replacement
Jul 30 , 2021
When an optical fiber link fails, the SFP transceiver in the port used to provide the link may need to be replaced. To replace a failed SFP transceiver with a new transceiver received from the CRU or FRU warehouse, use this procedure. Before the start Although many components are hot-swappable components, they can only be used when your system is inactive (no I/O operations). If the system is powe...

Common reasons why SFP transceivers stop working
Aug 18 , 2021
The small form factor (SFP) transceiver is a compact, hot-swappable module for computing in telecommunications and data communication applications. Due to people's needs, the increase in high-speed data transmission has led to a rapid increase in the demand for SFP modules. The application in the market is also getting wider and wider. SFP transceivers can be used in a variety of applications. How...

What is the difference between CWDM technology and DWDM technology?
Sep 01 , 2021
There are CWDM coarse wavelength division multiplexing technology and DWDM dense wavelength division multiplexing technology in WDM technology. The two technologies have been specifically mentioned in the previous article. From a literal point of view, these two technologies are different in the density of a band. , But the actual technology and application are still very different. ① Different wa...

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...
