ABSTRACT:
A laser driver outputs a data protocol signal as controlled by an extinction control signal. The data protocol signal has a header including first and second bit patterns. A laser outputs an optical signal in response to being excited by the data protocol signal. The first and second bit patterns are measured and used to calculate an extinction ratio. The calculated extinction ratio is compared with a desired extinction ratio to generate the extinction control signal.
