A fibre -optic wire is a new type of technology that transmits data down narrow, flexible strands of glass rather than wire. Its slightly more complex uses are high -speed internet signals, telecommunication and information transmission. The fiberoptic cable's technological features include a large bandwidth and interference resistance, as well as carrying data for long distances without signal degradation. Therefore channels with a capacity of four hundred MHz per kilometer, which can securely transfer anywhere from eight to sixteen voice phone lines or 300-500 tv channels at full resolution without distortion for forty three kilometers away from city centres and their noisome clutter 7],[12 another-certainly different-scale use than streaming data from satellite feed to email so quickly that you never notice any lag between hitting 'Send' and getting back an acknowledgment of receipt-are made possible by fiberoptical transmission Today, these cables are widely used in a variety of fields, such as internet access, cable TV, and telephone systems. With sufficiency and economy like this, fiberoptic cables have indeed become the protagonists of modern communication systems as things stand.
