Fiber optic patch cable is a type of optical fiber cable used to connect fiber optic equipment. It has fiber optic connectors on both ends and is used indoors to connect devices like computers to outlets or distribution centers. Fiber optic patch cables come in single-mode or multimode varieties and can have simplex, duplex, or hybrid connector configurations on either end.

2. What Is Fiber Optic Patch Cable?
Fiber optic patch cable is an optical fiber-
connected cable with fiber-optic connections on
both ends, sometimes known as Fiber optic patch
or fibers jumper cables.
It consists of two important fields of application: a
computer workstation, an outlet and fiber panels,
or a distribution center.
For indoor applications, only fiber-optic patch
cables are used.

3. FIBER OPTIC PATCH CABLES TYPES
Fiber optic patch cables can be subdivided into distinct fiber modes, cable structures, connection types,
polishing connector kinds, and cable sizes.
Fiber Cable Mode:
1. Single-mode fiber patch cables: 9/125 micron multiple single-move fibers and single-mode fiber optic
connectors are used on both ends of fiber optic patch cables. The cable jacket is normally yellow in
single mode.
2. Multimode fiber patch cables: Multimode fiber patch cables employ multimode fiber cables of 62.5/125
microns or of 50/125 microns and have multimode fiber optical connections at both ends. Usually, the
color of the multimode optic cable jacket is orange.

5. Fiber Cable Structure
1. Simplex fiber optic patch cables: Simplex fiber optic patch cables have one
fiber and one connector on each end.
2. Duplex fiber patch cables: Each end of a duplex fiber patch cable has two
fibers and two connections. To indicate polarity, each fiber is labeled "A" or "B,"
or separate colored connection boots are utilized.

6. Connector Types
For a complete list of connector types, see this fiber optic connector lesson.
1. Fiber patch cable with the same connection type on both ends: This fiber
patch cable has the same connector type on both ends, such as ST, SC, LC, FC,
and so on.
2. Fiber optic patch cables with separate connectors on either end are known as
hybrid fiber optic patch cables. One end may be SC, while the other may be LC,
ST, FC, or other.
