Functional Description
Transmitter Section
Design
The transmitter section uses a Fabry Perot (FP) laser as
its optical source, see Figure 2. The package has been
designed to be compliant with IEC 825 eye safety re-
quirements under any single fault condition. The opti-
cal output is controlled by a custom IC that detects the
laser output via the monitor photodiode. This IC pro-
vides both dc and ac current drive to the laser to ensure
correct modulation, eye diagram and extinction ratio
over temperature, supply voltage and operating life.
The transmitter section also includes monitor circuitry
for both the laser diode bias current and laser diode
optical power.
