10 Gigabit Multimode Fiber Standard
The 10 gigabit module standard is the Enhanced Small Form-factor Pluggable transceiver, generally called SFP+. To implement different 10GbE physical layer standards, many interfaces consist of a standard socket into which different physical (PHY) layer modules may be plugged. In SMF light follows a single path through the fiber while in MMF it takes multiple paths resulting in differential.
