Advantages of Fibre Optics
Fiber optic systems have many attractive features that are superior to electrical systems. These include improved system performance, immunity to electrical noise, signal security, and improved safety and electrical isolation.

Other advantages include reduced size and weight, environmental protection, and overall system economy, including:

• System performance (speed and reliability)
• Symmetrical bandwith (same upload and download speed)
• Difficulty to tap (data security)
• Increased bandwidth and capacity (flexible and upgradeable)
• Immunity to electrical noise
• No crosstalk
• Lower bit error rates
• Less restrictive in harsh environments
• Overall system economy
