Jacket: The protective outer covering of a cable.

Jumper: A fiber optic cable assembly with connectors on both ends.


Kevlar®: A strong, lightweight material used as a strength member, developed by Dupont.

kHz: One thousand cycles per second.

km: abbreviation for kilometer, or one thousand meters (1km=3280 ft)


LAN (Local Area Network): A communication network between two or more points within a relatively small geographic area (as opposed to a WAN).

Large Core Fiber: Generally any fiber with a core of 200 micron or greater.

Loose Tube: A type of cable where the fiber is contained in a subunit inside the cable jacket. 

Loss: The amount of signal power that is lost in connectors, splices, fiber, and external influences (bend, etc.), expressed in dB.

Loss Budget: The overall attenuation in a system.


m:  Abbreviation for meter.  1m=39.37

M: Abbreviation for mega, or one million.

mA: Abbreviation for milliamp, or one thousandth of an Amp.

Macrobend(ing): All macroscopic bending of a fiber from a straight line which cause light to leak out from the fiber, causing attenuation.

MAN (Metropolitan Area Network): A network larger than that of a LAN, a series of local area networks (LANs) covering a metropolitan area.

Mass Splicing: Splicing of many fibers (typically in ribbon fiber format).

Mechanical Splice: A fiber splice whereby two optical fibers are butted together and held via mechanical means (typically the use of index matching gel is used to minimize reflections).

MHz: Abbreviation for megahertz. One million Hertz (cycles per second).

Microbending: Mechanical stress on a fiber causing attenuation.

Micrometer: One millionth of a meter (abbreviation:  µm).

Microsecond: One millionth of a second (abbreviation:  µs).

Minimum Bend Radius: The smallest radius about which an optical fiber (or cable) can bend before an increase in attenuation occurs (usually specified by the manufacturer).

mm: Abbreviation for millimeter (one thousandth of a meter).

MM: abbreviation for multimode.

Mode: An electromagnetic wave traveling in a fiber.

Mode Field Diameter: A measure of the distribution of optical power intensity across the end face of a  singlemode fiber.

Mode Filter: A device that removes higher-order modes from an optical fiber (used mostly in testing).

Mode Stripper: A device that remove modes traveling in the cladding.

ms: Abbreviation for milliseconds (one thousandth of a second).

Multimode (MM) Fiber: An optical fiber that has a core large enough to propagate more than one mode of light. 


n: Abbreviation for nano (one billionth).

nm: Abbreviation for nanometer (one billionth of a meter).

ns: Abbreviation for nanosecond (one billionth of a second).

Numerical Aperture (NA): The light-gathering ability of a fiber.  The maximum acceptance angle (measured to the fiber axis).  Also the spread of light from the end of a fiber.

nW: Abbreviation for nanowatt (one billionth of a Watt).


O/E: Abbreviation for optical to electrical converter.  A device used to convert optical signals to electrical signals. 

OEM: Abbreviation for original equipment manufacturer.  A company that manufactures product for another company (private label).

Optical Fiber: A glass or plastic fiber that has the ability to act as a waveguide for light.

Optical Link Loss Budget: The maximum allowable loss in a fiber optic link before system performance degrades.  The budget is mostly determined by the output power of the transmitter.

Optical Power Meter (OPM): An instrument used to measure optical power at the end of a fiber.

Optical Return Loss (ORL): The ratio of optical power reflected from a component back towards the light source relative to the incident power (expressed in dB).

Optical Time Domain Reflectometer (OTDR): An instrument used to measure loss and reflections in a fiber link.


p: Abbreviation for pico (one trillionth).

pA: Abbreviation for picoamp (one trillionth of an Amp).


PC: Abbreviation for physical contact, typically refers to a type of connector and polish that allows fiber ends to come in contact, reducing backreflection and insertion loss.

Pigtail: A length of fiber (bare, buffered, or cabled) with a connector on only one end. The other end may be bare or attached to a source, detector, etc.

Planar Waveguide: A waveguide fabricated in a dielectric material.

PLC: Abbreviation for planar lightwave circuit. A device incorporating a planar waveguide.

Plenum: Air handling space under floors, in walls,and above drop ceilings where appropriately rated cables may be run.

Plenum cable (UL type OFNP): A cable whose smoke and flammability characteristics meet certain criteria allowing it to be run in plenum areas.

PON: Abbreviation for passive optical network. A network that brings optical fiber cabling and signals all or most of the way to the end user.

Preform: A glass rod with specific attributes from which optical fiber is drawn.


Radiation-hardened Fiber: A type of optical fiber made with materials designed to recover most of their initial properties (attenuation coefficient) after a period of time after exposure to radiation.

Rayleigh Scattering: The scattering of light caused by particles with dimensions much smaller than the wavelength of the of the light.  In optical fiber this is caused by minute imperfections along the fiber.

Receiver: Terminology to describe a piece of equipment that contains a detector and converts light signals to electrical signals.

Return Loss: See Optical Return Loss.

Ribbon Cable: A cable in which many fibers (typically 6, 12, or 24) are arranged in a flat, parallel manner and encapsulated in a binding material, forming a flat ribbon like cable.


s: Abbreviation for second.
