This object allows the management client to enable
laser safety control feature on the trunk side interfaces
by writing a true value to this object. If laser safety
control is enabled, the transmit laser on the trunk side is
shut when the receive signal is not available on the fiber.
A 'false' value disables this feature and is the default
value assigned to this object.
Laser safety control would not apply in case of splitter
protection on the optical switch.
