As part of its IEEE Get Program, the Institute of Electrical And Electronics Engineers (IEEE) has made the 802.3bm standard—specifying 40- and 100-Gbit/sec Ethernet transmission over fiber—available for free download. The 802.3bm standard was completed in 2015 and, as with other documents available through the Get Program, it became downloadable free-of-charge once it had been available as a PDF document for six months. The document’s official title is IEEE 802.bm-2015 Standard for Ethernet – Amendment 3: Physical Layer Specifications and Management Parameters for 40 Gb/s and 100 Gb/s Operation over Fiber Optic Cables.
The IEEE has established certain terms of use, to which an individual must agree before downloading the document.
