What is Co-axial Cable?
Co-axial includes a central copper wire surrounded by PVC insulation over which a copper mesh sleeve is placed. Again, the metal sleeve is shielded by an outer shield of thick PVC material, as shown in the figure.
The coaxial cable structure provides it with the right mixture of high bandwidth and good noise community. For 1 km cables, a data price of 10 Mbps is feasible. Higher data rates are applicable for shorter cables. Co-axial cables are generally used for cable TV and long-distance transmission within the telephone system.
Characteristics of Co-axial Cable
The main characteristics of the coaxial cable are as follows −
- There are two types of cables having impedance are available.
- It has a huge bandwidth and low losses.
- This cable is appropriate for point to point or point to multipoint software. This is the most broadly used medium for local area networks.
- These cables are valuable than twisted-pair cables, but they are economical than optical fiber cables.
- It has a data rate of 10 Mbps which can raise with the inner conductor’s increasing diameter.
- The attenuation is fewer as correlated to the twisted pair cable.
Advantages of Co-axial Cable
- It can be used for both analog and digital data transmission.
- It is relatively cheap as compared to fibre optic cables.
- It is simple to manage.
- It has brilliant noise immunity.
- It has a large bandwidth and low losses.
- It has less attenuation as distinguished from the twisted pair cables.
Disadvantages of Co-axial Cable
- Coaxial cables are more expensive.
- It is not consistent with twisted-pair cables.
- It is heavy as compared to twisted pair cables.
