The Role of Coaxial Cable in Broadband Networks

Coaxial Cable in Broadband Networks

Coaxial cables have been around for more than a century. Since they were first invented and patented in 1880, Best Coaxial Cable have played a vital piece in communication technology. Principally, these cables were utilized by cable TV companies to link their satellite antennae stations to deliver sound and pictures onto television sets at different homes and business establishments across the country. Further, coaxial cables were used by telephone companies as well as coupling satellite dish and television antenna with television sets.

However, coaxial cables are employed by several internet service providers for accessing their services and the internet. In the early days of Ethernet, coaxial cables were employed to connect networks with speeds limited for up to 10 Mbps. However, this was suppressed by the emergence of the usage of twisted pair cabling. Still, coaxial cables remained widely used for cable broadband networks.

Here are the contributions of coaxial cables in the distribution of internet data thru broadband:

Provides Protection of the Electrical Signal from Outside Interferences

Due to their physical characteristics, coaxial cables are effective in delivering an electrical signal from one end to the other. The interior of a coaxial cable is arranged in a concentric layer from the center to the outside. The inner conductor, usually a copper-clad steel located in the center inside the cable, is enclosed by an insulating layer or a dielectric material, followed by a series of shields, typically aluminum, and lastly by an outside insulating jacket. The shielded design of the cable permits the copper core to transfer data rapidly without any disturbance. Apart from that, environmental factors like bad weather, electrical noise and electromagnetic interferences are prevented from corrupting and destroying the signal.

Carries Radio-Frequency (RF) Energy

Coaxial cables are efficient in transferring radio-frequency energy. Thus, it is categorized (in the classification of cabling) as a “Radio Frequency (RF) Transmission Line”. Owing to the physical uniformity of the cable and further, by the arrangement and dimensions of the conductors, this gives the coaxial cables the capability to transport radio frequency energy rather than diffuse high-frequency signals. However, once the physical structure of the coaxial cable is disturbed, this results in the impairment of the medium in transmitting radio frequency.

Carries Greater Bandwidth and Faster Internet Speed

Coaxial cables can carry larger bandwidth compared to telephone lines. Bandwidth refers to the bulk of data that can be dispatched in a definite amount of time.  Because of this, coaxial cables have remarkable benefits in businesses that are operated by moving and uploading a substantial amount of files and data.

Serves as Fiber Optic Cables

While fiber optic cables can carry more additional data than coaxial cables, the cost of which is more expensive compared to the latter. Coaxial cables are convenient, given that installing the cables is fast and easy. Coaxial cables are most appropriate in residences and in small and medium-sized business establishments such as those that require an average-capacity of the data transmission network.

The role played by coaxial cables in broadband networks is crucial. People get connected, communicate and acquire knowledge through the medium. As more people gain access to the internet, these cables will be functional for an extended period of time.
