<p>An optical system that includes an analog laser transmitter having a burst operativemode is disclosed. The system further includes a power controller that is configuredto place the analog laser transmitter in the burst operative mode when a digitalenable signal is provided to the power controller. The power controller comprisesa reference voltage source, a ground node, and an input selector switch that isconfigured to select the reference voltage source when the digital enable signalis asserted, and alternatively, to select the ground node when the digital enablesignal is de-asserted. In a second exemplary embodiment, a method of operatingan analog laser transmitter is disclosed. The method comprises providing ananalog signal to the analog laser transmitter, and a digital enable signal toa controller circuit that is coupled to the analog laser transmitter. The methodfurther comprises turning on the analog laser transmitter when the enable signalis asserted, and turning off the analog laser transmitter when the enable signalis de-asserted.</p> |
