Functional Description
Transmitter Section
Design
A schematic diagram for the transmitter is shown in
Figure 2. The AFCT-5961TLZ/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 condi-
tions. The optical output is controlled by a custom IC
that detects the laser output via the monitor photodi-
ode. 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.
