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.

Rationale:
Type I fusion splicers are designed for hazardous environments specifically including potentially flammable or explosive atmospheres.
