适用范围：This Part of EN 4533 examines the termination aspects of fibre optic design for avionic installations. Bytermination is meant the mechanism used to interface from one component (usually a fibre) to another. This isnormally performed by a connector, which aligns the fibre with another component (usually another connector)to a sufficient accuracy to allow continued transmission of an optical signal throughout the operationalenvelope.This Part will explain the need for high integrity terminations, provide an insight into component selectionissues and suggests best practice when terminating fibres into connectors for high integrity applications. Adetailed review of the termination process can be found in Clause 4 of this part and is organised broadly inline with the sequence of a typical termination procedure.The vast number of cable constructions and connectors available make defining a single terminationinstruction that is applicable to all combinations almost impossible. Because of the problems of defining ageneric termination instruction, this handbook has concentrated on defining best practice for current to nearfuture applications of fibre optics on aircraft.This has limited the studies within this part to currently available ‘avionic’ silica fibre cables and adhesive filledbutt-coupled type connectors. Many of the principles described however would still be applicable for othertermination techniques. Other types of termination are considered further in the repair part of this handbook.In order to implement a fibre optic based system on an aircraft it is vital to ensure that the constituentelements of the system will continue to operate, to specification, over the life of the system. An importantaspect of this requirement is the need for reliable interconnection components. This is often expressed as theneed for reliable connectors, but in reality it is the need for a reliable cable to connector termination process.The essence of this requirement is the need to assure reliable light transmission through each opticalconnector throughout the operational envelope. This needs to be achieved through a robust process thatenables a high level of optical performance over the lifetime of the terminations.Many factors can contribute to an optical connector’s in-service performance, such as basic connector design,choice of optical fibre, cable, operating and maintenance environment etc. However, one of the main factorsgoverning in-service connector performance is the quality of the cable to connector termination.
