2 / 14 page  2 Package The overall package concept for the Agilent transceivers consists of three basic elements; the two optical subassemblies, an electrical subassembly and the housing as illustrated in Figure 1 and Figure 1a. The package outline drawing and pin out are shown in Figures 2, 2a and 3. The details of this package outline and pin out are compliant with the multisource definition of the 1 x 9 SIP. The low profile of the Agilent transceiver design complies with the 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. The electrical subassembly consists of a high volume multilayer printed circuit board on which the IC chips and various surface-mounted passive circuit elements are attached. The package includes internal shields for the electrical and optical subassemblies to ensure low EMI emissions and high immunity to external EMI fields. The outer housing including the duplex SC connector or the duplex ST ports is molded of filled nonconductive plastic to provide mechanical strength and electrical isolation. The solder posts of the Agilent design are isolated from the circuit design of the transceiver and do not require connection to a ground plane on the circuit board. Figure 1. SC Connector Block Diagram 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 transceiver by mating with duplex or simplex SC or ST connectored fiber cables.
