Infra-red laser energy may be present on the cable connected to the receiving (input) connector.
The transmitting (output) optical fiber connector and the monitoring (output monitor) connector
are equipped with shutters that automatically close when a cable is removed. To avoid potential
damage to the eyes, do not look directly into an optical fiber cable or a connector (whether
