| ESCON | Enterprise Systems Connection | Snap (duplex) | 2.5 mm | IBM mainframe computers and peripherals | |
| F07 | 2.5 mm | Japanese Industrial Standard (JIS) | LAN, audio systems; for 200 μm fibers, simple field termination possible, mates with ST connectors | ||
| F-3000 | Snap, with light and dust-cap | 1.25 mm | IEC 61754-20 | Fiber To The Home (LC Compatible) | |
| FC | Ferrule Connector or Fiber Channel | Screw | 2.5 mm | IEC 61754-13 | Datacom, telecom, measurement equipment, single-mode lasers; becoming less common |
| Fibergate | Snap, with dust-cap | 1.25 mm | Backplane connector | ||
| FSMA | Screw | 3.175 mm | IEC 60874-2 | Datacom, telecom, test and measurement | |
| LC | Lucent Connector, Little Connector, or Local Connector |
Snap | 1.25 mm | IEC 61754-20 | High-density connections, SFP transceivers, XFP transceivers |
| ELIO | Bayonet | 2.5 mm | ABS1379 | PC or UPC | |
| Lucxis | 1.25 mm | ARINC 801 | PC or APC configurations (note 3) | ||
| LX-5 | Snap, with light- and dust-cap | IEC 61754-23 | High-density connections; rarely used | ||
| MIC | Media Interface Connector | Snap | 2.5 mm | Fiber distributed data interface (FDDI) | |
| MPO / MTP | Multiple-Fiber Push-On/Pull-off | Snap (multiplex push-pull coupling) | 2.5×6.4 mm | IEC-61754-7; EIA/TIA-604-5 (FOCIS 5) | SM or MM multi-fiber ribbon. Same ferrule as MT, but more easily reconnectable. Used for indoor cabling and device interconnections. MTP is a brand name for an improved connector, which intermates with MPO. |
| MT | Mechanical Transfer | Snap (multiplex) | 2.5×6.4 mm | Pre-terminated cable assemblies; outdoor applications | |

| Opti-Jack | Snap (duplex) | ||||
| OPTIMATE | Screw | Plastic fiber, obsolete | |||
| OptoClip II | Snap (push-pull coupling) | None - bare fiber used | Proprietry Hüber & Suhner | Datacom and telcom; not common | |
| SC | Subscriber Connector or square connector or Standard Connector |
Snap (push-pull coupling) | 2.5 mm | IEC 61754-4 | Datacom and telcom; GBIC; extremely common |
| SMA 905 | Sub Miniature A | Screw | Typ. 3.14 mm | Industrial lasers, military; telecom multimode | |
| SMA 906 | Sub Miniature A | Screw | Stepped; typ. 0.118 in (3.0 mm), then 0.089 in (2.3 mm) | Industrial lasers, military; telecom multimode | |
| SMC | Sub Miniature C | Snap | 2.5 mm | ||
| ST / BFOC | Straight Tip/Bayonet Fiber Optic Connector | Bayonet | 2.5 mm | IEC 61754-2 | Multimode, rarely single-mode; APC not possible (note 3) |
| TOSLINK | Toshiba Link | Snap | most common is JIS F05 | Digital audio | |
| VF-45 | Snap | Datacom | |||
| 1053 HDTV | Broadcast connector interface | Push-pull coupling | Industry-standard 1.25 mm diameter ceramic ferrule | Audio & Data (broadcasting) | |
| V-PIN | V-System | Snap (Duplex) Push-pull coupling | Industrial and electric utility networking; multimode 200 μm, 400 μm, 1 mm, 2.2 mm fibers |

Famous quotes containing the word types:
“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
—Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
