3.7.5 Connecting Fibers
I. Introduction to the fiber connector
Before connecting the fibers, make sure the type of the connector and the fiber are
consistent with that of the optical interface.
Fiber connectors are indispensable passive components in optical fiber communication
system. Their application enables the removable connection between optical channel,
which makes optical system debugging and maintenance more convenient and transit
dispatching more flexible. Among multiple fiber connectors, only SC and LC will be
introduced here.
