good example of a schematic for
a power supply decoupling
circuit that works well with
these parts. It is further
recommended that a contiguous
ground plane be provided in the
circuit board directly under the
transceiver to provide a low
inductance ground for signal
return current. This recommen-
dation is in keeping with good
high frequency board layout
practices.
The Applications Engineering
The transceivers are delivered
with protective process plugs
inserted into the duplex SC or
duplex ST connector receptacle.
This process plug protects the
optical subassemblies during
wave solder and aqueous wash
processing and acts as a dust
cover during shipping.

choice of either a duplex SC or a
duplex ST connector interface,
while utilizing the same pinout
