    10. 13. Comparison Basis of Difference UTP STP Co-axial Fiber optic Bandwidth 10Mbps-100Mbps 10Mbps-100mbps 10Mbps 100Mbps-1Gbps Attenuation Very high Attenuation High Attenuation Low Attenuation Very Low Attenuation Segment Length 500metres 100metres 185m- 500m 2km – above. Installation Least expensive Costly than UTP Costly than Twisted Pair More costly to install. Cost Rs. 10 -20/m Rs. 20- 40 /m Rs. 250/m Rs. 700/m Interference Susceptibility More affected by EMI Lesser than UTP Good resistance to EMI Not affected Crosstalk More Relatively less Minimum No affect
