28 September 1994 Reliability evaluation for PON power splitters
Author Affiliations +
A key component to be used in PON systems is the power splitter. There is little information available on the reliability and lifetime of this component either under realistic field conditions or from accelerated stress testing. In the RACEa project FIRST (Fibre to the Residential Subscriber Terminal) a selection of accelerated lifetests have been performed on a small number of currently-available splitters, in order to make a preliminary evaluation of the suitability of such devices and the technologies they utilize. Outlined briefly are the main technologies used in the manufacture of optical splitters: fused-fiber, deposited silica planar waveguides, and ion-exchange planar glass waveguides. Samples from one manufacturer of each of the three technologies have been purchased for testing. An understanding of the component construction and materials allowed the relevant ageing tests to be chosen. The optical measurements, the reliability test procedures and the equipment used are described. A review of the initial results shows the key points of interest for each technology. The preliminary results of the accelerated testing are that none of the splitter designs tested here has shown an adequate reliability to meet a target specification.
