Connection procedure1) Plug one end of the network cable into the Ethernet RJ-45 jack of the switch to beconnected.2) Plug the other end of the cable into the RJ-45 port of the peer device.3.7.5 Connecting FibersI. Introduction to the fiber connectorBefore connecting the fibers, make sure the type of the connector and the fiber areconsistent with that of the optical interface.Fiber connectors are indispensable passive components in optical fiber communicationsystem. Their application enables the removable connection between optical channel,which makes optical system debugging and maintenance more convenient and transitdispatching more flexible. Among multiple fiber connectors, only SC and LC will beintroduced here.z SC fiber connectorFigure 3-16 SC connectorz LC fiber connector
