Gigabit Ethernet (802.3z) is designed to deliver a BER of 10^(-12), one
hundred times better, following the lead of Fibre Channel. This GbE
requirement is documented as objective "h" in section 36.1.2 "Objectives"
of 802.3z, and is referenced for fiber-optic links in note "a" of tables
38-4 and 38-8.
One would expect that ten gigabit ethernet (10GbE) would do at least as
well. In fact, one can argue that from a systems standpoint, the BER for
ten gigabit ethernet should be at least ten times better than gigabit
ethernet, making the 10GbE BER goal 10^(-13) or even 10^(-14). Certainly
it cannot be less than 10^(-12).
