Abstract
A device is provided that mitigates the effects of an optical network unit (ONU) that is in a rogue state. A main processor is arranged as part of a monolithic semiconductor chip, the main processor configured to process signals from an optical telecommunication connection. A laser driver controls a laser coupled to the laser driver. Hardware logic is arranged as part of the monolithic semiconductor chip and arranged physically separate from the main processor. The hardware logic independently effects the laser driver to turn the laser off or reduce power output of the laser significantly to mitigate the effects of the ONU in the rogue state.
Claims22
An apparatus for mitigating effects of an optical network unit (ONU) that is in a rogue state, the apparatus comprising:
- a main processor arranged as part of a monolithic semiconductor chip, the main processor configured to process signals from an optical telecommunication connection;
- a laser driver that controls a laser coupled to the laser driver;
- and
- hardware logic arranged as part of the monolithic semiconductor chip and arranged physically separate from the main processor,
- wherein the hardware logic independently effects the laser driver to turn the laser off or reduce power output of the laser significantly to mitigate the effects of the ONU in the rogue state.
A method for mitigating effects of an optical network unit (ONU) that is in a rogue state, the ONU including a main processor arranged as part of a monolithic semiconductor chip, the main processor configured to process signals from an optical telecommunication connection, the ONU further including a laser driver on board the monolithic semiconductor chip that controls a laser coupled to the laser driver, the method comprising:
- receiving a message signal indicating that the ONU is in the rogue state;
- turning off the laser or reducing a power output of the laser significantly independent of the main processor in response to receiving the message signal indicating that the ONU is in the rogue state.
