HFBR-59L1AL BLOCK DIAGRAM

Module Package

Agilent 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

HFBR-59L1AL. The connection

diagram for both modules 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 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.

Recommended Solder Fluxes

Solder fluxes used with the

HFBR-59L1AL should be

watersoluble, 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

hydrocarbons such as 1,1.1

trichoroethane or ketones such

as MEK, acetone, chloroform,

ethyl acetate, methylene

dichloride, phenol, methylene

chloride, or N-methylpyrolldone.
