What is coaxial cable?
Coaxial cables are a type of electrical cable consisting of two layers. The inner conducting layer is covered by an insulating layer. The term comes due to both the layers sharing the same geometric axis.
What is the design of coaxial cable?
Coaxial cable uses good conductors like copper in the inner layer to conduct electric signals. The copper layer is insulated by one to four layers of woven mettalic braid and tape. The design of coaxial cables helps in reducing leakage of electric current. It also reduces interference from external electromagnetic waves. This makes coaxial cables ideal for the transmission of weak signals.
What are the uses of coaxial cable?
Short distance coaxial cables have become popular in audio and visual purposes. Long-distance coaxial cables were used in the last century for telephone cables, radio networks, television networks et cetera. These have now been replaced with fiber-optic cables.
