Fiber Cable Overview - HP FlexNetwork HSR6802 Installation Manual

Fiber cable overview

CAUTION:
•
Never exert a fierce force when you insert or remove a fiber connector.
•
Never pull, press, or extrude the fiber fiercely.
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.

Fiber connectors are indispensable passive components in an optical fiber communication system.
They allow the removable connection between optical channels, which makes the optical system
debugging and maintenance more convenient. There are multiple types of fiber connectors.
36 shows an LC connector. Fiber ports of the HPE HSR6800 routers support only LC connectors.
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
Tensile load (N)
150
80
31
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 exists
Uses LEDs as the light source
often within LANs or distances of
a couple hundred meters within a
campus network
Crush load (N/mm)
500
