Question

Compare the characteristics of Fiber-Optic and Co-axial Cable Mention at least three points.

Answer 1

Sr No.	Aspect	Fiber-Optic	Co-axial Cable
1.	Bandwidth & throughput	Very high supports multi-Gbps, large data capacity over long distances.	Moderate from hundreds of Mbps to a few Gbps, less than fibre.
2.	Attenuation & distance	Very low signal loss works over long distances without repeaters.	Higher loss, shorter range, often needs amplifiers/repeaters.
3.	EMI & security	Immune to EMI (optical signal), highly secure and hard to tap.	Shielded from EMI but still affected; easier to tap than fibre.
4.	Cost & installation	Higher cost, requires skilled installation and special tools.	Lower cost, easier and cheaper to install.
5.	Physical & maintenance	Lightweight, non-conductive, but fragile; needs careful handling.	More robust and durable, but can corrode and needs maintenance.
