There will be an evolution in fiber optic transmission equipment used in the local loop between the present and the mid-1990s. Current applications in fiber transmission is, and has been, focused on interoffice and long-haul trunking. Presently, the local loop is dominated by wire and digital loop carrier systems, with some use of fiber. Fiber optic digital multiplexers are now penetrating the local loop, to be followed by synchronous multiplexers and standardized fiber optic interfaces in the near future.
