Module Package

Avago offers the Pin Through Hole package utilizing an

integral LC Duplex optical interface connector. The trans-

ceiver 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 HFBR-59L1AL. The connection diagram for both mod-

ules are shown in Figure 2. Figures 6a and 6b depict the

external configuration and dimensions of the module.

Installation

The HFBR-59L1AL can be installed in any MSA compli-

ant 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 pro-

cess 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.

Recommended Solder Fluxes

Solder fluxes used with the HFBR-59L1AL should be wa-

tersoluble, organic fluxes. Recommended solder fluxes

include Lonco 3355-11 from London Chemical West, Inc.

of Burbank, CA, and 100 Flux from Alpha-Metals of Jersey

City, NJ.

Recommended Cleaning/Degreasing Chemicals

Alcohols: methyl, isopropyl, isobutyl.

Aliphatics: hexane, heptane.

Other: naphtha. Do not use partially halogenated hydro-

carbons such as 1,1.1 trichoroethane or ketones such as

MEK, acetone, chloroform, ethyl acetate, methylene di-

chloride, phenol, methylene chloride, or N-methylpyroll-

done.

Also, Avago does not recommend the use of cleaners that

use halogenated hydrocarbons because of their potential

environmental harm.
