Coaxial Cables - Transmission Media in Networking

Transmission Media in Networking is the actual path over which am electrical signal goes it moves starting with one part then onto the next.

There are 2 types of Transmission Media in Networking used in Networking

1. Wired (Cables)

2. Wireless (Air)

In this session we will cover, the wired part of the Transmission Media in Networking. There are three types of wired transmission media,

1. Coaxial cables

2. Twisted pair cables

3. Fiber optic cables

Coaxial cables:

A coaxial cable or coax is a cable, is used in the transmission of audio, video and communication. Mainly coaxial cables are used network and broadband cable. These cables have high bandwidths and greater transmission capacity.

The adjacent figure is of a commonly used coaxial cable. As shown in the figure these cables have a metal male connector end that is screwed onto a female connector.

The Coaxial cables are two types:-

1) Thicknet (10Base5)

2) Thinnet ( 10Base2)

Thicknet, also known as Thick Ethernet or 10Base5.

Thinnet also known as Thin Ethernet or 10Base5, are antiquated Ethernet networking technologies.

OSI Layers with examples

Both technologies use coax that consists of solid copper core surrounded by an insulater. 10Base2 is known as cheper net, thin Ethernet, thinnet, and thinwire which is a variant of Ethernet that uses thin coaxial cable, terminated with BNC connectors. Here 10Base2 means

- 10 Mbps speed,

- Baseband signals and

- 200 metres length (actual usage is 185 metres).

And, 10BASE5 is known as thick Ethernet that as the first commercially available variat of Ethernet. Here 10Base5 means

- 10 Mbps speed,

- Baseband signals and

- 500 metres length.

Understanding the Thinnet and Thicket concepts into Transmission Media in Networking

The number 10: At the front of each identifier, 10 denotes the standard data transfer speed over these media- ten megabits per second ( 10Mbps).

The Word Base: Short for BAseband, this part of the identifier signifies a type of network the uses only one carrier frequency for signalling and requiress all network stations to share its use.

The segment type or segment lentgh: This part of the identifier can be a digit or a letter:

Digit: shorthand for how long (in metres) a cable segment may be before attenuation sets in. For example, 10Base5 can be no more than 500 meters long.

Letter: identifies a specific physical type of cable. For example, the T at the end of 10BaseT stands for twisted-pair.
