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.
connector.

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
Tensile load (N)

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
Crush load (N/mm)
