Figure 2 Functional Diagram
The receiver component converts the optical serial data into CML compatible electrical
data (RD+ and RD–). The Loss Of Signal (LOS) shows whether an optical signal is
present.
The transmitter converts CML compatible electrical serial data (TD+ and TD–) into
optical serial data. Data lines are differentially 100 terminated.
The transmitter contains a laser driver circuit that drives the modulation and bias current
of the laser diode. The currents are controlled by a power control circuit to guarantee
constant output power of the laser over temperature and aging. The power control uses
the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a
controlling signal, to prevent the laser power from exceeding the operating limits.
Single fault condition is ensured by means of an integrated automatic shutdown circuit
that disables the laser when it detects laser fault to guarantee the laser Eye Safety.
