What is Coaxial Cable?
Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference. It is primarily used by cable TV companies to connect their satellite antenna facilities to customer homes and businesses. It is also sometimes used by telephone companies to connect central offices to telephone poles near customers. Some homes and offices use coaxial cable, too, but its widespread use as an Ethernet connectivity medium in enterprises and data centers has been supplanted by the deployment of twisted pair cabling.
Differentiate between Broadband and Baseband Coaxial cable
Baseband cables are not capable of transmitting more than one signal at a time, and the transmissions are restricted to data and voice. Additionally, baseband cables exceeding 0.62 mile in length experience a steady drop in transmission rates unless an amplifier is used. However, advantages of using baseband cable are the associated low cost and the ease of use. Another benefit of using baseband cable is the absence of a modem because the cable's signals are already digital.
Broadband cables are capable of transmitting many signals simultaneously because each signal, or channel, travels at a different frequency. These multiple channels make it possible for broadband cables to transmit as much as 100 megabytes per second. Some other advantages of broadband cable are its capability to receive videos, as well as data and voice, and its potential to cover greater distances. Maintenance issues and high costs are some of the problems with broadband cable use.
