Abstract

Abstract:

The optica1 passive devices in ODN，such as optica1 fiber connector，optica1 power splitter，field-mountable optica1 fiber connector and optica1 fiber were analyzed. Based on the experience of our tests in recent years，the existing problems and reasons of the products were described. The quality assurance and contro1 of product were also suggested. Besides，it described the factors 1eading to testing errors which was easily overlooked in the test method and test procedure for insertion 1oss—the most important technica1 specification of optica1 passive devices.

Key words: ODN, optica1 fiber connector, optica1 power splitter, field-mountable optica1 fiber connector, quality, test
