Optical SFPs use a small laser to generate the fiber-optic signal. Keep the optical transmit and receive
ports covered whenever a cable is not connected to the port.
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments.
