scope:

FOCIS 17 presents the intermateability standard for connectors with the commercial designation MU, and is issued as an addendum to TIA/EIA 604, Fiber Optic Connector Intermateability Standards. The provisions of TIA/EIA 604 apply to this document.

Objective

Intermateability standards define the minimum physical attributes of mating connector components. Fully dimensioned components are not within the scope or intent of FOCIS 17.

The requirements in FOCIS 17 have been selected with the objective of ensuring that any combination of plugs and adapters conforming to the requirements of FOCIS 17 will mechanically intermate, and that intermated connector assemblies will meet their common level of performance.

The common level of performance of an intermated connector assembly is the least demanding set of performance requirements in the separate performance specifications of each of the products in the assembly; see TIA/EIA 604.
