The aerospace industry has always required the highest standards of workmanship. To ensure that the aerospace fiber optics industry adopts these high standards, it is essential that best practice methods and processes are followed in the in service inspection, evaluation, and cleaning of fiber optic termini and connectors.This document provides user information on best practice methods and processes for the in-service inspection, evaluation, and cleaning of multi-fiber push on (MPO) (referred to as multi-fiber) fiber optic interconnect components, test equipment, and test leads based on the information provided in AIR6031 and ARP6283. This document provides the user with a decision making tool to determine if the fiber optic components are acceptable for operation with multi-fiber fiber optic termini.
