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.

To date (3/09), these FOCIS documents exist:

FOCIS 1: Biconic
FOCIS 2: ST
FOCIS 3: SC, SC/APC
FOCIS 4: FC, FC,APC
FOCIS 5: MTP/MPO
FOCIS 6: Panduit FJ
FOCIS 7: 3M Volition
FOCIS 8: Mini-MAC (Withdrawn)
FOCIS 9: Mini MPO (Withdrawn)
FOCIS 10: Lucent LC, LC/APC
FOCIS 11: Siecor SCDC/SCQC (not yet approved)
FOCIS 12: Siecor/Amp MT-RJ
FOCIS 13: SFFSC, SFOC, LX-5

FOCIS 14: SMC-SB
FOCIS 15: MF

FOCIS 16: LSH (E2000)
FOCIS 17: MU

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 FO-4.3 Subcommittee on Fiber Optic Interconnecting Devices.
