What do different types of fibre connectors look like?

		ST: A metal cylindrical keyed bayonet type fibre connector that is spring loaded and attached using a push and twist motion. It is most widely used as a connector for multimode networks Ferule - 2.5mm

		SC: A plastic push/pull type connector that is used for multimode and singlemode due to it's excellent performance. Often used on GBIC's and legacy switches Ferule - 2.5mm

		LC: A push/pull type fibre optic connector similar to SC but half the size. Often found on SFP/mini GIBC's and current generation switches. Ferule - 1.25mm

		FC: A metal threaded screw on type connector with an alignment key, popular with singlemode fibres but less commonly used than SC and LC. Ferule - 2.5mm

		MU: A push/pull type fibre connector similar to LC but mainly used in Japan. Ferule - 1.25mm

		MTP/MPO: A push/pull high density ribbon fibre connector which can take 12-24 fibres. The MTP is a technical enhancement of the MPO. Ferule - 2.5x6.4mm

		MT-RJ: A duplex only push/pull small form factor fibre connector (about half the size of an SC) which houses two fibres and mates with locating pins on the plug. Easy to install but not widely used. Ferule - 2.45x4.4mm

		E2000/LX-5: A push/pull fibre connector similar to an LC but with a spring loaded shutter over the end of the fibre protecting from damage and dust contamination. Ferule - 2.5mm

		ESCON: A duplex push/pull connector developed by IBM with fixed shroud and keyed. Ferule - 2.5mm

		SMA: A threaded fibre optic connector developed and manufactured by Amphenol, but rarely used any more. The SMA-905 has a straight ferule, the SMA-906 has a stepped ferule; the latter has better insertion loss. Ferule - 2.5mm

		VF-45: A duplex only push/pull small form factor connector which is available as plug and jack Ferule - 2.5mm?
