Package
The overall package concept for these devices consists
of the following basic elements; two optical subas-
semblies, a electrical subassembly and the housing as
illustrated in the block diagram in Figure 3.
The package outline drawing and pin out are shown in
Figures 4 and 5. The details of this package outline and
pin out are compliant with the multisource definition of
the 2 x 5 DIP. The low profile of the Avago Technologies
transceiver design complies with the maximum height
allowed for the LC connector over the entire length of
the package.
The electrical subassembly consists of high volume
multilayer printed circuit board on which the IC and
various surface-mounted passive circuit elements are
attached.

CASE
The optical subassemblies are attached to the electrical
subassembly. These two units are then fitted within the
outer housing of the transceiver. The housing is then
encased with a metal EMI protective shield.
The electrical subassembly carries the signal pins that
exit from the bottom of the transceiver. The solder
posts are designed to provide the mechanical strength
required to withstand the loads imposed on the trans-
ceiver by mating with the LC connectored fiber cables.
Although they are not connected electrically to the
transceiver, it is recommended to connect them to
chassis ground.
