ARINC Specification 801 is intended to provide standardization of a fiber optic interconnect assembly, which is composed of a connector, fiber optic cable, and fiber optic termini for the air transport industry. The goal is to avoid the proliferation of different designs of connectors to serve the same functions on different aircraft models. This specification defines generic fiber optic connectors needed for commercial aircraft. The connector family is based around a standard terminus (fiber optic contact) design and associated cavity, which is used in all of the connector styles and arrangements. The standard terminus comes in variants for different cable types. All termini will fit the same cavities in the connectors and are intended to be interchangeable.
