This detail specification defines fiber optic fusion splicers acceptable for the installation and repair of a wide range of optical fibers and cables with virtually no insertion loss, particularly in aerospace applications, but not in flammable or explosive atmospheres (Type II). The requirements for acquiring the splicer described herein shall consist of this specification and the latest issue of AS6479.

This detail specification defines fiber optic fusion splicers acceptable for the installation and repair of a wide range of optical fibers and cables with virtually no insertion loss in hazardous environments (potentially flammable or explosive atmospheres, Type I), particularly aerospace applications. The requirements for acquiring the splicer described herein shall consist of this specification and the latest issue of AS6479.

This SAE Aerospace Standard (AS) defines fiber optic fusion splicers acceptable for the installation and repair of fiber optic interconnects in aerospace applications. Two different application environments are defined, depending on whether there is risk of flammable vapor or hazardous atmosphere being present. Equipment suited to flammable or hazardous environments may be over specified for factory, depot, or other relatively safe environments. To address these different application environments, two types of fusion splicer will be specified in applicable detail specifications: Type I. For hazardous environments specifically including potentially flammable or explosive atmospheres. Type II. For environments in which it is established that there is no risk of flammable or explosive vapors being present.

ARP6366 defines a comprehensive and widely-accepted set of specification guidelines to be considered by those seeking to use or design fiber optic sensors for aerospace applications. Some of the most common applications for fiber optic sensing within aerospace include inertial guidance and navigation (gyros) and structural monitoring (temperature, strain, and vibration sensing). Common sensor infrastructure elements include: transmitting and receiving opto-electronics (e.g., sources and receivers); multiplexing and demultiplexing optics; optical cabling; and signal processing (both hardware and firmware/software).
