ADVENTAGES AND DISADVENTAGES WIRED TRANSMISSION MEDIA

1. TWISTED PAIR: adventages
   

a) inexpensive and reasiasilyly availabe
b) flexible and light weight
c) easy to work with and install
disadventage
a) suseptibility to interference and noise
b) attenuation problem. for analog, repeaters needed every5.6km.for
digital, reapeters needed 2.3km
c) relative low bandwidth (3000Hz)

2. COAXIAL CABLE: adventage
a) higher bandwidth
b) can be tapped easly
c) much less susceptible to interference than twisted pair
disadventage
a) high attenuation rate makes it expensive over long distance
b) bulky

3. FIBER_OPTIC CABLE: adventage
a) greater capacity (brandwidth of up to 2 Gbps
b) smaller size and lighter weight
c) lower attenuation
disadventage
a) expensive over short distance
b) reguire highly skillied installiers
c) adding additional nodes is difficult
