Repeat the above steps with the other end of the cable.

Optical fiber
CAUTION:
Use the same types of transceiver modules, pigtail cords, patch cords, and fiber cables. If you use
single-mode optical fibers, the transceiver modules, pigtail cords, patch cords, and fiber cables must
be single-mode.
Optical fiber
Optical fibers are widely used in fiber-optic communications, which are advantageous for
long-distance communications.
Optical fibers can be classified into the following types:
•
Single mode fiber—It has a core size of 10 µm or smaller, and has a lower modal dispersion. It
carries only a single ray of light. It is mostly used for communication over longer distances.
•
Multi-mode fiber—It has a core size of 50 µm or 62.5 µm or higher, and has a higher modal
dispersion than single-mode optical fiber. It is mostly used for communication over shorter
distances.

Optical fiber cable
An optical fiber cable is a cable containing one or more optical fibers. The optical fiber elements are
typically individually coated with plastic layers and contained in a protective tube. Optical fiber cables
fall into single-mode and multi-mode.
Patch cord
A fiber that has connectors at both ends is called a patch cord. A patch cord connects one optical
device to another for signal routing. Patch cords fall into single-mode and multi-mode patch cords.
•
Single-mode patch cord—The jacket is yellow. It permits transmission over longer distances.
•
Multi-mode patch cord—The jacket is orange. It permits transmission over shorter distances.
Patch cords are classified into SC, LC, FC, and so on based on interface type. The length of a patch
cord can be 0.5 m (1.64 ft), 1 m (3.28 ft), 2 m (6.56 ft), 3 m (9.84 ft), 5 m (16.40 ft), 10 m (32.81 ft),
and so on.
