From the theory of total interior reflection, light-weight rays beamed to the optical fibers can propagate inside the Main for nice distances with exceptionally concise attenuation or reduction in depth, creating fiber optics the ideal strategy for transmitting info over long distances.
The optical fibers Employed in fiber optics are sometimes crafted from plastic but most frequently are made of glass. A standard glass optical fiber features a diameter of 125 micrometers (μm) or 0.

It achieves this by swapping acknowledgment of data reception and retransmitting shed or dropped packets. Normal protocols employed at the transportation layer incorporate TCP and User Datagram Protocol.
Within the late 1990s by 2000, sector promoters, and study organizations like KMI, and RHK predicted significant will increase in demand from customers for communications bandwidth as a consequence of amplified usage of the Internet, and commercialization of various bandwidth-intensive shopper services, like video on desire. Internet Protocol knowledge targeted traffic was growing exponentially, at a speedier price than integrated circuit complexity experienced increased beneath Moore's Legislation.
