There are two main types of internet lines: the HFC type "coaxial cable line" that combines optical fiber and coaxial cable, and the FTTH type "optical line" that uses optical fiber cable. Since these communication methods are completely different, each has its own. Optical Fiber is the type of guided media is made of plastics and glasses which is used to transmit the signal is in light form or optical form. It provides the high bandwidth (B). Its Installation and implementation is not so easy like coaxial cable. However, real-world decisions are not based on performance alone;. In the ever-evolving landscape of telecommunications and data transmission, the choice between coaxial cable and fiber optic cable is pivotal for optimizing network performance, scalability, and cost-efficiency. While coaxial cables can still meet basic internet needs, especially in hybrid setups, fiber-optic technology offers far better. Coaxial cable uses copper and electrical signals, while fiber optic uses light, giving fiber clear advantages in speed, bandwidth, and interference resistance. Coax can still be a practical, lower-cost option for business internet, but shared bandwidth and congestion can lead to slower speeds and.
