Title:Measure, Store, and Access F.O. Transceiver Test Data
Issuing Committee:As-3 Fiber Optics And Applied Photonics Committee
Scope: This document addresses methods to measure, store, and access test data from built-in-tests that are available in present commercial fiber optic transceivers and that will be available in future transceivers in order to overcome the difficulties that presently deny the use of such tests on aerospace platforms.
Rationale: This document addresses methods to measure, store, and access test data from built-in-tests that are available in present commercial fiber optic transceivers and that will be available in future transceivers in order to overcome the difficulties that presently deny the use of such tests on aerospace platforms.
