With the approval of EIA/TIA 492AAAD grade multimode fiber, enhanced versions of OM3 50 micron optical fiber will now carry the designation of OM4. Though frequently used in the past as the defacto nomenclature for enhanced OM3 glass, the OM4 designation, which identifies 50-micron glass capable of 10 gigabit Ethernet out to 550 meters, will more clearly identify fiber optic cable performance levels. HCM uses Corning optical glass for all its standard products. All HCM fiber optic cable constructions will be available with Corning’s OM4 fiber optic glass.
The OM1, OM2 and OM3 fiber nomenclature originated in the ISO / IEC-11801, second edition standard and is presently being adopted into TIA and other standards. It is expected that the OM4 term will be used in upcoming releases of ISO / IEC documents.
