What is the difference between baseband coaxial and broadband coaxial cable?

Answer 1

The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.

Answer 2

Baseband coaxial cables are 50 ohm cables used for 'digital transmission'. For 1Km cables the bandwidth is 1-2 Gbps. Longer cables can be used with low data rates or periodic amplifiers.

Broadband coaxial cable are 75 ohm cables used for analog transmission. They use standard Cable Television technology. To transmit digital signals on an analog network, each interface must have converters i.e analog to digital for outgoing bit stream n vice versa

Another difference b/w baseband and broadband is that broadband systems have developed dual cables. Since broadband is used for large area, it requires amplifiers which are unidirectional. In dual band systems two identical cables run together, one used for outgoing data, one for incoming data. Different bandwidths are given for inbound and outbound cables. Eg: for 300MHz , 5-30MHz for inbound and 40-300MHz for outbound.
