Cable

TPC (Twisted Pair Cable) 

It is used in star topology and telephone network.

Its quality depends on number of twisting per inch and metal quality.

It supports distance up to 100 meters.

It supports bandwidth in Gbps.

RJ45, RJ48 and RJ11 connectors are used.

It follows a color standard .i.e. standardize by TIA/EIA (Telecommunications Industry Association/Electronics Industry Alliances).

It is available into different category.

Category 1

Category 2

Category 3

Category 4

Category 5

Category 5e

Category 6

Category 7

Types of Twisted Pair Cable

Note: - Function of color cable in standardizes cable color code.
1 and 2 – To Receive Data

3 and 6 – To Transmit Data

4 and 5 – ISDN (Integrated Service Digital Network)

FOC (Fiber Optic Cable)

It is used in different networks like WAN connectivity, point-to-point connectivity, telephone line, internet service etc.

It transfers data in the form of light.

This light is generated by LED or laser.

It is available into 2 modes.

Single mode – Only one light signal can pass at a time.

Multi mode – multiple light signals at different angle travel at a time.

Its distance coverage capacity is into miles.

It uses SC or ST.

Very less effect of EMI (Electro Magnetic Interference).

It uses fiber or glass thread to transmit data.

Fiber Optic cable can be connected to another Fiber optic cable by splicing.

Coaxial Cable

Used in BUS topology.

It has single cooper cable .i.e. used to transmit and receive data.

It supports maximum 10 Mbps data transmission.

Its distance coverage capacity up to 185 meters.

It uses BNC and T connectors.

It is available in different category RG58 & RG59 .i.e. thick & thin simultaneously.
