ANSI/TIA-568-C.3 specifies performance and transmission requirements for premises optical fiber cable, connectors, connecting hardware, and patch cords. Optical fiber transition methods used to connect cabling from an array connector to simplex or duplex connectors are also specified.
ANSI/TIA-568-C.3 “Optical Fiber Cabling Components” was developed by the TIA TR-42.8 Telecommunications Optical Fiber Cabling Systems Subcommittee (which has since been merged with the TR-42.11 Optical Systems Subcommittee) and published in June, 2008. A 5-page errata sheet that corrects errors related to the deletion of unused definitions, adds revised text supporting duplex and array polarity figures, and clarifies mating cycle test specifications has been issued to supplement the published content of TIA-568-C.3.
Significant changes from the previous edition of this Standard include adoption of the ISO nomenclature for optical fiber cable types (i.e., OM1, OM2, OM3, OS1, and OS2), the addition of recommended connector strain relief, housing, and adapter color coding to support installations when color is used to identify fiber type, and an increase in the specification of minimum OFL bandwidth for 62.5/125 Ωm optical fiber cable from 160 MHz•km at 850 nm to 200 MHz•km at 850 nm.
ANSI/TIA-568-C.3-1 “Addendum 1, Addition of OM4 Cabled Optical Fiber and Array Connectivity” published in December, 2011 and expands the content of TIA-568-C.3 with new specifications for 50/125 μm laser-optimized OM4 cabled optical fiber and components for array connectivity. Polarity schemes for array connectors are also addressed in this Addendum.
