We are all used now to twisted pair and fiber, and not everyone already recalls this time. But believe or not, the first media used for the Ethernet networks was the coaxial cable or coax. It remained as most common media for years, but has been recently replaced by twisted pair and fiber optics in modern LAN solutions. As seen ...
Transmission media can and will be affected by the noise coming from inner and outer sources. That is when noise immunity factor kicks in. Since different types of media has greater or smaller affects by the noise it is necessary to choose type of media depending on situation. Noise is affecting data signals, but since fiber-optic does not use electric ...
Network designer require to consider type of media transmission depending on network needs. Different media have different specifications for throughput, cost, noise immunity, size, and scalability.
Throughput
Throughput is one of the main factors for choosing transmission method. While in theory signal can travel with speed of light, in practice it is limited by media physical characteristics and multiplexing techniques. Since the ...
Term “latency” is referring to a delay between transmission and receipt of the signal. In the electric cable there is time difference happening between time when user press the button and moment when server receives signal. Many physical factors are affecting latency, such as length of the wire/cable and amount of nodes between server and signal sender. Different devices for ...
What are the differences between Point to Point vs Point to Multipoint Communication Schemes? When do you choose Point to Point and when - Point to Multipoint?
Of course, everything comes down not only for a type of services and network you are planning and building (Is it LAN, WAN or MAN?) and also it's type - Access, Core, Last Mile?
Different types of transmissions ...
What is Time Division Multiplexing? Supporting our customers daily, we sometimes get this question, and mostly because various references mention, that EPON and GPON protocols use TDM - Time Division Multiplexing in a direction from ONU to OLT. We also discuss that more in details in this article, which talks about Layer 1 structure in GPON/EPON.
To understand this, let's answer the ...
