(1) I believe the standard says 5 km, but (most?) manufacturers promise 10 km
(2) Requires a mode-conditioning patch cable
(3) "SR" denotes short-range LAN, "SW" is short-range WAN
(4) Sometimes referred to as "10G Ethernet multimode fiber" or "OM3 fiber". See TIA-492AAAC.
(5) Four 2,5G waves
(6) Cisco-proprietary
(7) Four 10G lanes
(8) Four 10G lanes, Cisco-proprietary
(9) Four 10G lanes
(10) Ten 10G lanes
(11) Four 25G waves
