SCOPE 1.1 Purpose This specification covers design and performance requirements of fib
6、er optic splices for optical distribution systems in aerospace vehicles and provides a means of procurement of such devices. 1.2 Specification Approach Fiber optic cable design characteristics are uniquely related to various aerospace vehicle applications. As a result, splices are necessarily constr
7、ucted for specific cable types. Evaluation of the splice performance shall be with the cable type for which it was intended as defined in the splice detail specification (see Section 3). Typically, fiber optic splices have unique assembly instructions. Splices that are qualified to the same detail s
8、pecification must be assembled using the same procedure and tools. All assembly instructions shall be presented and documented in accordance with this specification.1.3 Part Number Structure The part number structure for each splice shall be as follows: MA5405/1-001MA5405: Procurement Specification
