Definitions for "MMF"
An optical fiber that that has larger-diameter inner core and supports more than one propagating mode. Multi-mode fiber is designed to support relatively low-speed transmission over relatively short distances.
multimode fibre
Fiber optic cable in which the signal or light propagates in a single mode or path. Since all light follows the same path or travels the same distance, a transmitted pulse is not dispersed and does not interfere with adjacent pulses. MMF fibers can support up to 2 kilometers and are limited mainly by the amount of attenuation. Refer to SMF.

An abbreviation for MAKE MONEY FAST; also the generic name for any of the useless, futile, and often illegal pyramid schemes that promise to "make $5 into $50,000" or "GET RICH QUICK" by spamming newsgroups. They don't work, they're annoying, they're illegal, and people will flame you, so don't ever do it. Posting MMF-type posts is very bad netiquette.
