FDM multiplexing
What are main differences of WDM vs FDM multiplexing? Let us delve in details.
In this type of multiplexing, every subchannel is having its own frequency band, which is the reason technology is called frequency division multiplexing. Each subchannel has been modulated with different frequencies before being multiplexed to the single channel. It allows usage of single line for up ...
Baseband is type of transmission that is using current to send signal over the wire as digital wave. It can transmit only one signal at a time, due to requirement of the exclusive use of the wire. This type of transmission is allowing only on device to transmit in the network at one time, while other devices need to wait ...
Every network has its capacity or bandwidth. This constant defines amount of data that can be transmitted in one second. Sometimes it is called bandwidth (although there are different uses of term bandwidth in networking). The data throughput is measured in amount of bits transmitted per one second. The prefixes define amount of zeros after the number - kilobits for ...
Usually, when it comes to serial interfaces, especially used in Video Over Fiber transmission product range, for features like PTZ control for camera's tilting and zooming, questions about Simplex, Half Duplex and Duplex comes out. It is also important in Ethernet physical transmission. This is why this post, and we hope you find it helpful!
Any type of data transmission can ...
Modern buildings are being built with pre-installed wiring capable of digital transmission. At the same time, old buildings are being modernized in order to use benefits of digital transmission. However, some of them might be using telephone lines for internet access. Unfortunately, telephone lines can transmit only analog signals. If computer needs to access network through the telephone lines, the ...
There are two possible ways of signal transmission in data network - digital and analog.
Computers use electrical signals for communication over the network. The voltage of the signal determines its strength and pressure. While computer generates electrical signal, it is possible that data would travel in electric current form, light pulses form, or wavelength form, depending on the type of ...
