Functional Description
Transmitter Section
Design
A schematic diagram for the transmitter is
shown in Figure 2. The AFCT-5964TLZ/TGZ/
ATLZ/ATGZ/NLZ/NGZ incorporates an FP laser
as its optical source. All part numbers have
been designed to be compliant with IEC 825
eye safety requirements under any single fault
condition and CDRH under normal operating
conditions. The optical output is controlled by
a custom IC that detects the laser output via
the monitor photodiode. This IC provides 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 also includes monitor circuitry
for both the laser diode bias current and laser
diode optical power.
