Cut the top of the wires even with one another. Insert the wires into the RJ-45 end and make sure
4.
the wires extend to the front of the RJ-45 end and make good contact with the metal contacts in the
RJ-45 end and in the correct order.
Crimp the RJ-45 connector with the crimping pliers until you hear a click.

Optical fiber

Optical fibers feature low loss and long transmission distance.
Optical fibers can be classified into single mode fibers and multi-mode fibers. A single mode fiber
carries only a single ray of light; a multi-mode 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.

Single mode 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

Multi-mode fiber
Larger core than single mode 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
