Implementation of a TDM passive optical network for subscriber loop applications

An experimental prototype system for subscriber loop applications that has been implemented using a passive optical network architecture is described. The system, known as MACNET, uses time-division multiplexing and transmission over a network of single-mode optical fibers and couplers to provide narrowband digital service access to 16 customers. Experience gained from developing the system is outlined. Future transmission options, including a fixed-bit-rate customer access approach to allow early network application of this technology, are described.<
