Advantages and disadvantages of Fiber optics

• Optical transmission is immune to electromagnetic interference and crosstalk. While others are immune to interference
• Optical fibers have less loss of signal strength than other wires, after every 30 miles we need to use a repeater, whereas in copper, we should insert repeaters at an interval of 2.8 miles .
• Optical fiber is more secure, no easy tapping on the cable
• But optical fibers are more expensive than other cables.

Outlines:

• Physical Transmission
• Wireless
• TCP/IP
• DNS
• Router
• Internet
• Web 2.0
• RFID
