RECOMMENDED PRACTICE

ARP6283™/1

Issued 2020-03

Reaffirmed 2025-10

In-Service Fiber Optic Inspection, Evaluation, and Cleaning,

Best Practices, Expanded Beam Termini

RATIONALE

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 for the in-

service inspection, evaluation, and cleaning of expanded beam (EB) fiber optic interconnect components (termini, alignment

sleeves, and connectors), test equipment, and test leads.

ARP6283/1 has been reaffirmed to comply with the SAE Five-Year Review policy.
