IEEE announced the availability of 802.3bm, IEEE Standard for Ethernet Amendment: Physical Layer Specifications and Management Parameters for 40 Gbps and 100 Gbps Operation Over Fiber Optic Cables.
The amendment reduces “lane count” for 100 Gbps applications (from 10 lanes at 10 Gbps each to four lanes at 25 Gbps each), expands the reach for 40 Gbps services to 40 kilometers and expands Energy Efficient Ethernet capability to include optical...
