The design of a TDMA system for passive optical networks

Abstract

The authors describe the design methodology and implementation details of a time-division multiple access (TDMA) system which has been developed to allow point to multipoint operation of passive optical networks. This TDMA bit transport system transparently handles the multiplexing and control functions required for passive splitting optical networks. The system is generic and, with relatively simple interfacing, applicable to switching systems worldwide. The design has been implemented in ASIC (application-specific integrated circuit) technology for a forthcoming UK field trial of fiber in the subscriber loop.<>
