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.

1)  Remove the protective cap from the connector of the fiber and clean the surface of the fiber.  

2)  Remove the protective cap from the optical interface of the switch, and plug one end of the fiber 

into this interface. 

Step 3: Connect the other end of the fiber connector to the corresponding device. 

 

When the optical interface has not been connected with a fiber connector or its dustproof cover is open, 

there might be some invisible radiation emitted from the optical interface. So do not stare into the optical 

interface directly. 

Cover the optical interface if there is no connector plugged in.
