Package
The overall package concept for these devices consists
of the following basic elements; two optical subassem-
blies, two electrical subassemblies 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 subassemblies consist of high volume
multilayer printed circuit boards on which the IC and
various surface-mounted passive circuit elements are
attached.
The receiver electrical subassembly includes an internal
shield for the electrical and optical subassembly to en-
sure high immunity to external EMI fields.

The optical subassemblies are each attached to their
respective transmit or receive electrical subassemblies.
These two units are then fitted within the outer housing
of the transceiver that is molded of filled nonconduc-
tive plastic to provide mechanical strength. The hous-
ing is then encased with a metal EMI protective shield.
The case is connected to signal ground and we recom-
mend soldering the four ground tabs to host card signal
ground.
The PCBs for the two electrical subassemblies both car-
ry the signal pins that exit from the bottom of the trans-
ceiver. The solder posts are fastened into the molding of
the device and are designed to provide the mechanical
strength required to withstand the loads imposed on
the transceiver 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.
