. 1) signal range (Bandwidth) because the frequency of light very high Bandwidth made available to a wider range of data can be sent and received with a high transmission rate. In theory, may have reached the current bps 1014 light fibers can be used to send information about 1,0 km, 1 Mbps in the distance, this is because the response time of the photo diode light unit takes 10-9 seconds, usually light fibers can be used to send audio data simultaneously, 30,0 channel and due to the high data rate transmission suitable for thus. Audio, video and digital data from computers at the same time in the system, ISDN (Integrated Services Digital Network)
. 2.) none of the induced electromagnetic wave Fiber Optic Cable because they are made from silica glass, which is a leading power, and is therefore not an electromagnetic induction from outside, such as lightning Thunder. Wave TV Radio waves and light fibers is the pot of saroloha loop from electromagnetic or radio signals, as well as to pak (sparks), electrical, so the error is less than 10-9. 10-6
3) loss to low- Fiber Optic Cable in a loss in the current lowest value is 0.2 db/Km (copper wire or Coaxial Line loss minimum 1 dB/Km)
. 4 channel spacing) Tuan Tuan station spacing signal signal (Repeater) will increase due to loss Fiber Optic cables in low due to loss of signal is being sent (Signal loss). So it may take a new signal p Lance scooters for distances up to 20-30. miles, while the required copper wire, PVC scooters every 2.8 mile in delivering digital
5) number of tokens in-there are a lot of Fiber Optic Cable, because only a single line. Can contain a large number of communication channels with three-channel audio and video data (Computer Network) with a clear visual separation, phone. (Computer, Radar Data), cable TV, the TV (Video Conference: a remote meeting needs to send a signal and audio signal simultaneously)
. 6) the number of the signal to pick up. The diameter of the Fiber Optic Cable size 250 micron. Therefore, within the cable, Fiber Optic Cable consists of 1 a lot, so for example, in cable Fiber Optic Cable consists of 12 lines. 0.49 inches. Optical fibre cables leading to smaller and lighter weight make the wasted space to hang up and install at least to hang up the less
. 7.), there are no limits regarding the use of radio frequencies. Using radio frequency, which is the electromagnetic wave propagation in the air. Has been allocated and controlled by regulatory agencies. Fiber Optic communications are using Fiber Optic light signal through a Cable wire, do not need permits
.
8) security (Security) high on the espionage information as possible is the only way the Optic Fiber cable connection only, which in practice cannot be performed. Depending on the interference (Jamming) electromagnetic waves from
. 9) Fiber Optic System lifetimes are long service life up to 25 years, while the system of microwave and satellite has a life of approximately 15 year
