OM5 and SWDM

OM5 and SWDM: Are We Ready?


Abstract

Recently, a new multimode fiber (MMF) standard was developed to support a wide range of wavelength multiplexing (from 840 nm to 953 nm), targeting next-generation network applications such as 100G and 400G Ethernet. ANSI/TIA-492AAAE, the new wideband multimode fiber standard, was approved for publication in June 2016. In October 2016, the International Organization for standardization/International Electrotechnical Commission (ISO/IEC) determined the nomenclature for wideband multimode fiber cable: OM5.
