Project Description

ARINC 801 Connectors

Physical Contact Connectors – Circular Connectors

Amphenol Fiber Systems International (AFSI) produces the ARINC 801 cylindrical fiber optic connector suite for aerospace and military applications. Based on the commercial ARINC 801 specification, this series features a removable alignment sleeve retainer (ASR) for ease of termini end face cleaning, guide pins for precision alignment and a scoop proof shell design. It is available in standard D38999 plug and wall mount shells. Inserts are available to support 2 to 32-channels and can support both PC and APC.

AFSI also offers the companion ARINC 801 terminus which uses a standard 1.25mm ferrule and sleeve that can be terminated with standard LC termination procedures. The terminus can be inserted or removed from the connector with a standard size 16 contact removal tool. The terminus is available in both multimode and single mode versions. The fiber optic contact provides low insertion loss (0.3dB max, multimode) and back reflection (-55dB, APC). In addition to the standard PC endface option, AFSI’s ARINC 801 termini are offered with an APC end face for applications requiring reduced back reflection.
