Fiber Optic Connector Intermateability Standards (FOCIS)

Fiber Optic Connector Intermateability Standards (FOCIS)

EIA/TIA FOCIS Documentation

A FOCIS document is an TIA/EIA term for Fiber Optic Connector Intermateability Standard. It is a component standard written for manufacturers to follow to insure that their connector will be intermateable with other manufacturer's connectors of the same type. They are published with a document number format TIA-604-XX.

According to the TIA:

"Intermateability standards define the minimum physical attributes of mating connector components. Fully dimensioned component are not within the scope or intent of FOCIS. The requirements of FOCIS have been selected with the objectives of ensuring that any combination of plugs and adapters conforming to the requirements of FOCIS 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."

TIA-604-XX standards are created by TIA TR 42.13 Subcommittee on Fiber Optic Interconnecting Devices.
