Optical Fibre Specs for Multimode Fibre

This section provides optical fibre specifications for IEC 60793-2-10 MMF (Multimode Fibre) for Solace PubSub+ 3560s.

The TC 86 series of subordinate specifications for media characteristics are IEC 60793-2 (most notably -10 and -50).

EC 60793-2-10/50 are referenced in ISO/IEC 11801, which defines performance categories. ISO/IEC 11801 performance categories are most commonly referenced in various application standards such as IEEE-802.3 (Ethernet) and ANSI/INCITS-T11 FC (Fibre Channel).

In North America, TIA/EIA has parallel specifications for fibre characteristics referenced in the TIA 568B Structured Cabling Standard.
