Module Package
Avago Technologies offers the Pin Through Hole package
utilizing an integral LC-Duplex optical interface connector.
The transceiver uses a reliable 850 nm VCSEL source and
requires a 3.3 V DC power supply for optimal system
design.
Module Diagrams
Figure 1 illustrates the major functional components of the
AFBR-5921ALZ. The connection diagram for both modules
are shown in Figure 2. Figure 6 depicts the external
configuration and dimensions of the module.
Installation
The AFBR-5921ALZ can be installed in any MSA-
compliant Pin Through Hole port. The module Pin
Description is shown in Figure 2.
Solder and Wash Process Capability
These transceivers are delivered with protective process
plugs inserted into the LC connector receptacle. This
process plug protects the optical subassemblies during
wave solder and aqueous wash processing and acts as
a dust cover during shipping. These transceivers are
compatible with industry standard wave or hand solder
processes.
