Abstract:
1. A transmitter comprising: a fault detection circuit operable to generate disable signals if a fault is detected, each disable signal having a respective rising edge and a falling edge; a disable circuit operable to generate a mask disable signal and to disable the component in response to the disable signals for a predetermined duration of time sufficient to maintain an average power generated by the component at or below a predetermined level; the disable circuit comprising a signal detection circuit operable to detect disable signals, a mask-signal generating circuit coupled to the signal detection circuit and operable to generate a mask signal when one of the edges of a first disable signal is detected, and a latching circuit coupled to the mask-signal generating circuit and operable to generate a mask disable signal if the mask signal is being generated and the other edge of a subsequent disable signal is detected; and a light emitting source driver operable to drive a light emitting source for fiber-optic communications, the light emitting source driver disabled if a disable signal is generated and disabled if a mask disable signal is generated.
