The electrical subassembly con-
sists of a high volume multilayer
printed circuit board to which the
IC chips and various surface-
mount passive circuit elements
are attached.
The package includes internal
shields for the electrical and
optical subassemblies to insure
high immunity to external EMI
fields and low EMI emissions.
The outer housing, including the
duplex SC connector, is molded
of filled non-conductive plastic to
provide mechanical strength and
electrical isolation. The solder
posts are isolated from the circuit
design of the transceiver, while
they can be connected to a
ground plane on the circuit
board, doing so will have no
impact on circuit performance.
The transceiver is attached to a
printed circuit board with the
nine signal pins and the two
solder posts which exit the
bottom of the housing. The two
solder posts provide the primary
mechanical strength to withstand
the loads imposed on the trans-
ceiver by mating with the duplex
SC connectored fiber cables.

The package outline drawing and
pin out are shown in Figures 2
and 3. The details of this package
outline and pin out are compliant
with the multisource definition of
the 1x9 single in-line package
(SIP). The low profile of the
Hewlett-Packard transceiver
design complies with the
39.12
MAX.
(1.540)
maximum height allowed for the
duplex SC connector over the
entire length of the package.
The optical subassemblies utilize
a high volume assembly process
together with low cost lens
elements which result in a cost
effective building block.
