Advantages

• Greater capacity
• Smaller size and light weight
• Lower attenuation
• Electromagnetic isolation

But Fiber can be damaged easily and optical transmission is unidirectional, so need two fibers or two frequencies for two-way communication.  Fiber and fiber interfaces are more expensive.

Advantages

• Cheaper
• Easy to handle and install
• Can be used with several kinds of technologies like televisions, cameras, computers, telephones
• It can support multiple signals travelling through the same cable unlike coaxial cables
