Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
A kind of novel optical fiber telecommunications system, as it is shown in figure 1, include sending optical transmitter and receiver, light sender unit, repeater, light receipts
Letter machine, reception optical transmitter and receiver and optical fiber.
The outfan of described transmission optical transmitter and receiver is connected with the input of light sender unit；The outfan of described smooth sender unit and light
Fine connection；The input of described repeater is connected with optical fiber, and the outfan of repeater is connected with optical fiber；Described smooth receiver defeated
Enter end to be connected with optical fiber；The outfan of described smooth receiver is connected with the input receiving optical transmitter and receiver.
Repeater includes the joints of optical fibre, photo-coupler, relaying photodetector, light judgement regenerator and relaying light source.
The input of the described joints of optical fibre is connected with optical fiber；The outfan of the described joints of optical fibre through photo-coupler, in
Continue photodetector and light judgement regenerator with relay light source input be connected；The outfan of described relaying light source is with optical fiber even
Connect.
Light sender unit includes manipulator and transmits light source, and the input of described manipulator is connected with sending optical transmitter and receiver；Described
The outfan of manipulator is connected with optical fiber；The described outfan transmitting light source is connected with manipulator.Light sender is to realize electrical/optical
The optical transmitter and receiver of conversion.It is made up of light source, driver and manipulator.Its function is will to come from the signal of telecommunication pair sending electricity terminal
The light wave that light source sends is modulated, and becomes modulated light wave, modulated optical signal is coupled to optical fiber the most again or optical cable goes to pass
Defeated.Electricity terminal is exactly conventional electronic communication equipment.
Light receiver includes collection of letters photodetector and image intensifer, and the input of described collection of letters photodetector is with optical fiber even
Connect；The described outfan of collection of letters photodetector is connected with the input of image intensifer；The outfan of described image intensifer and reception
Optical transmitter and receiver connects.Light receiver is the optical transmitter and receiver realizing optical electrical conversion.It is made up of photodetector and image intensifer.Its function
It is the optical signal that optical fiber or optical cable transmission are come, is changed into the signal of telecommunication through photodetector, then, then by this faint signal of telecommunication warp
Amplifying circuit is amplified to enough level, and the electric end delivering to receiving terminal draws.
Optical fiber constitutes the transmission channel of light, and its function is the modulated optical signal sent by transmitting end, through optical fiber or optical cable
Long-distance transmissions after, be coupled to the photodetector of receiving end up, complete transmit information task.

Length processed is also limited (such as 1Km).Therefore a fibre circuit there may be the problem that multifiber is connected.Then,
Connection between optical fiber, the connection of optical fiber and optical transmitter and receiver and couple, the use to the passive device such as the joints of optical fibre, bonder is must
Indispensable.
The most practical optical fiber telecommunications system all uses direct detection system.Direct detection system is exactly direct at transmitting terminal
Signal is modulated on light wave, and receiving terminal photorectifier directly the light wave detection recuperated under medical treatment be original signal be
System.Sending optical transmitter and receiver and reception optical transmitter and receiver is exactly general signal of telecommunication equipment, such as carrier terminal equipment or TV image send and set with acceptance
Standby etc..Sending optical transmitter and receiver is then that the signal of telecommunication is changed into optical signal, receives optical transmitter and receiver and optical signal is changed into the equipment of the signal of telecommunication.
The effect sending optical transmitter and receiver is to be processed by the signal of telecommunication of transmission, is added on semiconductor laser, makes signal of telecommunication modulated light wave,
Then this brewed light wave is sent into optical fibers.Brewed light wave is sent to receive the semiconductor light of optical transmitter and receiver through optical fibers
Detection on fulgurite.The signal of telecommunication obtained after detection through suitable process again send acceptance electricity terminal, then by Electric signal processing.
Here it is the process of whole fiber optic communication.This process and general radio communication process are quite similar.Certainly light leads to
The space propagation means of letter are optical fiberss, and this is different from general radio communication in the situation of space propagation electric wave
