2 February 1993 System specification and requirements for fiber-in-the-loop systems
Author Affiliations +
In Europe, massive deployment of Fiber in the Loop (FITL) in the 1990's will require that systems meet different national standards as well as international (CCITT and ETSI) recommendations. In addition, the US based Bellcore recommendations are used as a reference by some European operating companies. A number of technical issues are under study, and data from field trials is being collected by various operating companies to aid in definition of system specifications and requirements. However, specification differences between countries will continue to exist, and arriving at general and global specifications will require detailed study of a number of issues. In this paper we examine such issues encompassing: 1-fiber and 2-fiber transmission techniques for FITL telephony systems, including Time Division Multiplexing/Time Division Multiple Access (TDM/TDMA) and Time Compression Multiplexing (TCM), optical plant requirements including backreflection and directivity requirements on passive optical network components, and the effect of FITL round trip delay (RTD) on network performance. The goal of this work is to provide an analysis of these issues in order to clarify some of the discrepancies between standardization organizations and provide operating companies a global solution for FITL.
