| In [[fiber-optic communication]], a '''single-mode optical fiber''' ('''SMF''') is an [[optical fiber]] designed to carry only a single [[ray (optics)|ray of light]] (mode). Modes are the possible solutions of the [[Helmholtz equation]] for waves, which is obtained by combining [[Maxwell's equations]] and the boundary conditions. These modes define the way the wave travels through space, i.e. how the wave is distributed in space. Waves can have the same mode but have different frequencies. This is the case in single-mode fibers, where we can have waves with different frequencies, but of the same mode, which means that they are distributed in space in the same way, and that gives us a single ray of light. Although the ray travels parallel to the length of the fiber, it is often called [[transverse mode]] since its [[Electromagnetic radiation|electromagnetic]] vibrations occur perpendicular (transverse) to the length of the fiber. The 2009 [[Nobel Prize in Physics]] was awarded to [[Charles K. Kao]] for his theoretical work on the single-mode optical fiber.<ref>Nobel Prize Citation http://www.nobelprize.org/nobel_prizes/physics/laureates/2009/kao-facts.html</ref>

| Like [[multi-mode optical fiber]]s, single mode fibers do exhibit [[modal dispersion]] resulting from multiple spatial modes but with narrower modal dispersion. Single mode fibers are therefore better at retaining the fidelity of each light pulse over longer distances than multi-mode fibers. For these reasons, single-mode fibers can have a higher [[Bandwidth (computing)|bandwidth]] than multi-mode fibers. Equipment for single mode fiber is more expensive than equipment for multi-mode optical fiber, but the single mode fiber itself is usually cheaper in bulk. {{Citation needed|date=June 2013}}

| A typical single mode optical fiber has a core diameter between 8 and 10.5 [[µm]]<ref name="arcelect">{{cite web | title = Fiber Optic Cable Tutorial | url = http://www.arcelect.com/fibercable.htm | author = ARC Electronics | date=2007-10-01 }}</ref> and a cladding diameter of 125 µm. There are a number of special types of single-mode optical fiber which have been chemically or physically altered to give special properties, such as [[dispersion-shifted fiber]] and [[nonzero dispersion-shifted fiber]]. Data rates are limited by [[polarization mode dispersion]] and [[chromatic dispersion]]. {{asof|2005}} data rates of up to 10 gigabits per second were possible at distances of over {{convert|80|km|0|abbr=on}} with commercially available transceivers ([[Xenpak]]). By using [[optical amplifier]]s and dispersion-compensating devices, state-of-the-art [[DWDM]] optical systems can span thousands of kilometers at 10 Gbit/s, and several hundred kilometers at 40 Gbit/s.{{cn|date=November 2013}}

| The lowest-order bounds mode is ascertained for the wavelength of interest by solving [[Maxwell's equations]] for the boundary conditions imposed by the fiber, which are determined by the [[Fiber_optics#Principle_of_operation|core]] diameter and the refractive indices of the core and [[Cladding (fiber optics)|cladding]].

| Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. The basic connector unit is a connector assembly. A connector assembly consists of an adapter and two connector plugs.
| |
| Due to the sophisticated polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are generally assembled onto optical fiber in a supplier’s manufacturing facility. However, the assembly and
| |
| polishing operations involved can be performed in the field, for example to make cross-connect jumpers to size.
| |
| | |
| Optical fiber connectors are used in telephone company central offices, at installations on customer premises, and in outside plant applications. Their uses include:
| |
| * Making the connection between equipment and the telephone plant in the central office
| |
| * Connecting fibers to remote and outside plant electronics such as Optical Network Units (ONUs) and Digital Loop Carrier (DLC) systems
| |
| * Optical cross connects in the central office
| |
| * Patching panels in the outside plant to provide architectural flexibility and to interconnect fibers belonging to different service providers
| |
| * Connecting couplers, splitters, and Wavelength Division Multiplexers (WDMs) to optical fibers
| |
| * Connecting optical test equipment to fibers for testing and maintenance.
| |
| | |
| Outside plant applications may involve locating connectors underground in subsurface enclosures that may be subject to flooding, on outdoor walls, or on utility poles. The closures that enclose them may be hermetic, or may be “free-breathing.” Hermetic closures will prevent subjection of the connectors within to temperature swings unless they are breached. Free-breathing enclosures will subject them to temperature and humidity swings, and possibly to condensation and biological action from airborne bacteria, insects, etc. Connectors in the underground plant may be subjected to groundwater immersion if the closures containing them are breached or improperly assembled.

| | |
| The latest industry requirements for optical fiber connectors are in [http://telecom-info.telcordia.com/site-cgi/ido/docs.cgi?ID=SEARCH&DOCUMENT=GR-326& Telcordia GR-326, ''Generic Requirements for Singlemode Optical Connectors and Jumper Assemblies''.]
| |
| | |
| A ''multi-fiber'' optical connector is designed to simultaneously join multiple optical fibers together, with each optical fiber being joined to only one other optical fiber.
| |
| | |
| The last part of the definition is included so as not to confuse multi-fiber connectors with a branching component, such as a coupler. The latter joins one optical fiber to two or more other optical fibers.
| |
| | |
| Multi-fiber optical connectors are designed to be used wherever quick and/or repetitive connects and disconnects of a group of fibers are needed. Applications include telecommunications companies’ Central Offices (COs), installations on customer premises, and Outside Plant (OSP) applications.
| |
| | |
| The multi-fiber optical connector can be used in the creation of a low-cost switch for use in fiber optical testing. Another application is in cables delivered to a user with pre-terminated multi-fiber jumpers. This would reduce the need for field splicing, which could greatly reduce the amount of hours necessary for placing an optical fiber cable in a telecommunications network. This, in turn, would result in savings for the installer of such cable.

| OS1 and OS2 are standard single-mode optical fiber used with wavelengths 1310 nm and 1550 nm (size 9/125 µm). OS1 is defined in [[ISO/IEC 11801]], OS2 in [[ISO/IEC 24702]].
