Fiber optic connectors chart

Optical connectors are installed on fiber patch cable ends to provide cable attachment to a receiver, transmitter or other cable. Optical connectors can enable quicker connection and disconnection. All connectors have 4 basic components: connector body, ferrule, cable and coupling device.

Fiber optic connectors Features
Low insertion loss and back reflection loss
Free-floating ceramic ferrule
UL-rated plastic housing and boot
Boots in a variety of colors
High precision alignment

Optical connector	Long form	Coupling type	Ferrule diameter	Standard	Typical applications
FC connector		Screw	2.5mm	IEC 61754-13	Datacom, telecom, measurement equipment, single-mode lasers; becoming less common
ST connector	Bayonet	Bayonet	2.5mm	IEC 61754-2	Multimode, rarely single-mode; APC not possible (note 3)
SC connector	Subscriber Connector	Snap (push-pull coupling)	2.5mm	IEC 61754-4	Datacom and telcom; extremely common
LC connector	Lucent Connector	Snap	1.25mm	IEC 61754-20	High-density connections,SFP transceivers,XFP transceivers
MPO/MTP connector		Snap (multiplex push-pull coupling)	2.5×6.4mm	IEC-61754-7; EIA/TIA-604-5 (FOCIS 5)	SM or MM multi-fiber ribbon.
