What is the principle of fiber repeaters?
Optical fibers use optical pulses to transmit information along the optical line, instead of using electrical impulses to transmit information along the cable. At one end of the system is the transmitter, the starting point of the information to the fiber line. The received electronic pulse information of the transmitter is derived from the copper wire cable, and then the information is processed and converted into an equivalent coded optical pulse.
Repeater (Repeater) weighing and sending device is one of the most simple, but also the most widely used interconnection equipment. Repeaters are only suitable for Ethernet and can link up two or more than two Ethernet links. The repeater amplifies and amplifies the data signals transmitted over the cable, and then retransmit them to other cable sections. For protocols above the link layer, several sections of cables interconnected by repeaters are not different from a single cable (except that the interrupt itself causes a certain time delay).A repeater is a network interconnection device on the physical layer that acts as a means of generating signals (i.e., amplifying and shaping the original signal). An optical fiber repeater is one of the material that carries information and is an optical fiber
The fiber will be reflected back to the glass if the above do not want to see, look at this: is by resending the data signal or forwarding, to expand the network transmission distance to generate signals (i.e., amplifying and shaping of the original signal). Principle: a repeater is a device for connecting network lines, often used for two-way forwarding of physical signals between two network nodes. The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length.
A light emitting diode or an injection laser is used to generate an optical pulse, and a lens is used to focus the light pulses into the optical fiber medium so that the light pulses are transmitted along the line in the optical fiber medium. From the principle of internal total reflection, light pulses are easy to move through optical fiber lines. The principle of internal reflection in fiber shows that light can not flow out of glass when the incident angle exceeds the critical value;
