router or other network communication devices there are inevitably limits the scope of signal transmission, how to expand the network signal transmission range of it? .Repeater (Repeater) is to solve this problem and the birth of the product. .

What is the repeater

in long-distance communications, repeaters have the following meanings:

an amplification of the input analog signal enhancement device .regardless of the input signal type (analog or digital). .

repeater is used to enhance the signal on the cable, the signal sent farther, to extend the network length. .When the electrical signals sent over the cable, the signal strength will increase with decreasing length of the pass. .Therefore need to re-strengthen the signal repeater to increase the data transmission distance. .

or one for frequency conversion and power enhanced modules or devices such as relay satellite, which divided uplink frequency and downlink frequencies, is mainly used for signal enhancement and frequency difference transfer. .

also explained that the repeater is a device connected to the network line, commonly used in physical signals between two network nodes, two-way forwards work. .Repeater is the simplest networking equipment, mainly to complete the physical layer functions, is responsible for the physical layer in the two nodes on the transmission of information by bit, to complete a copy of the signal, adjust and zoom functions, in order to extend the length of the network. .Because of the loss, on the wire of the signal power will gradually decay, decay to a certain extent will cause signal distortion, therefore, a receive error. .Repeater is to solve this problem and design. .

normal circumstances, the repeater is connected to both ends of the same media, but some repeaters can also be done in different media adapters work. .In theory, the use of repeaters is infinite, and therefore the network can be extended indefinitely. .In fact this is impossible, because the network are the standard range of the signal delay specific provisions, the repeater can only be effective within the provisions of this work, otherwise it will cause a network failure. .

due to transmission line noise, or digital signals carrying information analog signal only limited transmission distance, repeater function is to regenerate the received signal and sends, thereby increasing the signal transmission distance. .Maximum standard length of each net 185 meters, up to five segments, thus increasing the repeater, the maximum network cable length can be increased to 925 meters. .In general, the repeater is part of both ends of the network segment, rather than the subnet. .

repeater can connect two LAN cables, retiming and regeneration of digital signals on the cable, and then send out these functions is the first layer of the OSI model - the typical physical layer functions. .Repeaters is to increase the local area network coverage area. .Repeater only the data on any cable segment is sent to another section of cable, and regardless of whether the data is not suitable for incorrect data or data segment. .

fiber optic repeater (also known as converters or single-mode fiber optic multi-mode converter) is mainly used in single-fiber multimode fiber or single and double fiber conversion, can be applied to optical wavelengths (850nm / .1300nm/1310nm/1550nm) and the conversion from the relay, the module and FDDI, Fast Ethernet, and Ethernet cable and the Taken Ring protocol and standard compatibility, support for Ethernet 100M (155M); 1000Mbps (1.25G .) fiber-optic transmission speed. .
