Fiber cable overview

CAUTION:
• Never use excessive force when you insert or remove a fiber connector.
• Never use excess force when you pull, press, or extrude the fiber.
Optical fibers can be classified into single-mode optical fibers and multi-mode optical fibers. A
single-mode optical fiber carries only a single ray of light, and a multi-mode optical fiber carries
multiple modes of lights.

Core
Dispersion
Light source and
transmission distance
Table 12 lists the allowed maximum tensile load and crush load for the fiber.
Single-mode optical fiber
Small core (10 micrometers or less)
Less dispersion
Users lasers as the light source often
within campus backbones for distance
of several thousand meters
27
Multi-mode optical fiber
Larger core than single-mode
optical fiber (50 micrometers, 62.5
micrometers or greater)
Allows greater dispersion and
therefore, signal loss occurs
Uses LEDs as the light source
often within LANs or distances of
a several hundred meters within a
campus network
