Functional Description-Transmitter Section
Design
The transmitter section uses a Fabry-Perot laser as its optical source. This laser
source is mounted in an OSA separated from the printed circuit board. The OSA has
been designed to be compliant with IEC 825 Class 1 and CDRH Class 1 eye safety
requirements. The optical output is controlled by a custom IC that detects the laser
output via the monitor photodiode as shown in Figure 3. This IC provides both DC and
AC current drivers to the laser to ensure correct modulation, eye diagram and
extinction ratio over temperature, supply voltage and life.
PCB Mounting
The model has two solderable mounting studs. These studs are not electrically
connected. The transceiver is designed for common production processes. It may be
wave soldered and aqueous washed provided that the process plug is in place. Each
process plug can only be used once during processing, although with subsequent use,
it can be used as a dust cover.
