ADSL or fiber optics: which connection has the highest speed?

June 12, 2021 - 2 minutes read

Fiber can carry more information over greater distances and in less time than any other communication medium, such as the photo above from the late 1970s showing cables of equal capacity illustrates so well. Fiber’s bandwidth and capacity over distance mean fewer cables, fewer repeaters, less power, and less maintenance. 

Both telecommunications companies and cable television operators use fiber for economic reasons, but the cost justification implies adopting new network architectures to take advantage of the virtues of fiber. Designers and installers of local area networks (LANs) and houseplants have now realized that they too must adopt new network architecture. An in-plant cabling network should also be less expensive if done with fiber instead of copper. Converting copper networks is easy with media converters, devices that convert most systems to fiber optics.

Fiber optic communication networks


The Internet use to have always been relied on a fiber optic backbone. It began as part of the telephone network, which at that time was mainly voice, but it has become the largest communications network as data traffic has far exceeded voice traffic. Today, telecommunications companies are migrating their voice communications to Internet Protocol (IP) to reduce costs.

Cable television (CATV)

Most cable television systems are also using TM Unifi Malaysia fiber in their backbones. Cable television companies use fiber because it gives them greater reliability and gives them the chance to offer fresh services, such as telephony and Internet connection.

Cable TV used to have a dreadful reputation for dependability, but in reality, it was not an issue with the service nonetheless with the network topology. These cable TV companies use very high-frequency analogue signals, up to 1 GHz, which has high attenuation over coaxial cable. To deploy a system throughout a city, cable television needs many amplifiers (repeaters) to reach the user at the end of the system, usually 15 or more.
