Breakout-style fiberoptic cable (also called breakout cable or fanout cable), is an
optical fiber cable
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with p ...

simplex
In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope in any given dimension. ...
optical fiber
An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at ...
s packaged together inside an outer jacket. This differs from
distribution-style cable, in which tight-buffered fibers are bundled together, with only the outer cable jacket of the cable protecting them. The design of breakout-style cable adds strength for ruggedized drops, however the cable is larger and more expensive than distribution-style cable. Breakout cable is suitable for short
riser and
plenum applications and also for use in
conduits, where a very simple cable run is planned to avoid the use of any
splicebox or spliced
fiber pigtails.
Because each fiber is individually reinforced, the cable can be easily divided into individual fiber lines. Each simplex cable within the outer jacket may be broken out and then continue as a
patch cable, for example in a
fiber to the desk application in an office building. This enables
connector termination without requiring special junctions, and can reduce or eliminate the need for

patch panels or an
optical distribution frame. Breakout cable requires terminations to be done with simple connectors, which may be preferred for some situations. A more common solution today is the use of a
fanout kit that adds a jacket to the very fine strands of other cable types.
Ribbon fanout pigtails
Ribbon fanout pigtails are made of ribbon fiber optic cables. It is generally installed in closet area or horizontal patch extension from consolidation point to the workstation outlets.
It includes: jacket ribbon fanout pigtails and bare ribbon fanout pigtails.
Jacket ribbon fanout pigtails have outer jacket.
Bare ribbon fanout pigtails have no outer jacket and generally protected by transparent tube.
Bunch fanout pigtails
Bunch fanout pigtails are made of multi-core round bunch fiber optic cable, which is also called distribution fiber optic cable. It is generally installed in closet area like rack mount or wall mount splice boxes or patch panels.
