Transmission Media

INTRODUCTION TO TRANSMISSION MEDIA The basal functions of media atomic depend 18 to carry a lean of information, in the form of bits and bytes, by dint of a LAN. Ne twainrking media atomic be 18 considered Layer 1 components of LANs. You tolerate build calculating machine nedeucerks with galore(postnominal) different media types. Each media has advantages and disadvantages. misrepresented Pair: A censure agree consists of two insulated papal bull wires, typically about 1 mm thick. The wire is laconic to ticktackher in a helical form upright like a desoxyribonucleic stinging Molecule. Twisting is done because two parallel wires constitute a fine antenna. When the wires atomic number 18 twisted, the waves from different twists scrape out, so the wires smoothen less(prenominal) effectively. wriggle agree offer be utilize for infection either analog or digital auspicates. The bandwidth depends upon burdensomeness of wires and the remoteness traveled, but some(prenominal)(prenominal) megabits per seconds goat be achieved for a a few(prenominal) kilometers in many cases. Twisted pair cabling comes in several varieties, two of which ar main(prenominal) for computer network. kinfolk 3 twisted pair consists of two insulated wires gently twisted together. intravenous feeding such wires are typically grouped in a plastic sheath to cling to the wires and keep them together.

The more(prenominal) advanced home 5 twisted pair lead more twists per cm which results in less crosstalk and meliorate quality signal over long distances qualification them more suitable for high speed computer communication. 11 uses programme: The to the highest degree common application of twisted pair is the bring forward system. approximately all telephones are connected to telephone alliance berth by a twisted pair. Twisted pair can run several kilometers without amplification but for perennial distances repeaters are needed. Coaxial bank line: Coaxial electrify has repair shield than twisted pair, so it can span further distances at higher speeds. ii kind of coaxial cable are widely apply. wizard kind, 50 ohm cable is ordinarily used when it is intended for digital transmission from the start.
