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 ...
What is C-band after all? What's L-band or U-band? Here in our CATV products range, and elsewhere on web you will see those terms. This is a topic of today's blog post.
The development of the transmission equipment for the fiber optic networks has been progressing very fast over last few years. New types of networks allow longer distances, higher speeds ...
The data applied to the OSI model is entirely different on the beginning when sent to the Application layer and at the end when transformed by all seven OSI layers. Each layer is adding its own piece of information to the initial data. All these pieces are addressed to the correlating layers at the receiver node. In order to explain ...

Differences Between FBT and PLC splitters
Also it is pretty clear visually shown on a infographic above (at least we hope so, as a lot of work are done to create above infograph), here's a description of what you can see above.
Optical networks require signal being splitted somewhere in design to serve for multiple ...
Layer 1 - or physical layer in OSI model, is basically built on a one single model type - single fiber, and each ONU has 1 fiber connected (not including the 1+1 backup cases, which is a special case, and will be reviewed in more details in our blog.
Heart of the any GPON or EPON network is OLT - Optical ...
Here it is - your new business plan for a EPON or GPON - exact standard really does not matters here. Probably you have also strong influence from a marketing, operations and other departments. And first, what you want to delve in and start to evaluate - is a prices of EPON equipment itself. Which supplier offers cheapest ONU's? Can ...
The first layer in OSI model is called Physical layer. It is working directly with the hardware, sending and receiving signals through the Network Interface Card (NIC).
While changing voltage for the copper wires it also can use light pulses for the fiber-optic cable. If the NIC has wireless receiver/transmitter it can receive/send signals as the electromagnetic waves.
After signals are detected ...
The main function of the Data Link layer is to receive data packages from network layer and convert them to the frames that are ready to be transmitted by the first layer in OSI model - the Physical layer. The frame would include not only data packages, but also the sender’s and the receiver’s network addresses, as well as error ...
