Fiber Optic Connector Intermateability
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.
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.

these are always being updated or new ones added. Check connector
manufacturers or TIA for the latest versions.
