Package and Handling
Information
Package Information
All HFBR-0400 Series
transmitters and receivers are
housed in a low-cost, dual-inline
package that is made of high
strength, heat resistant, chemically resistant, and UL 94V-O
flame retardant ULTEM® (plastic
(UL File #E121562). The
transmitters are easily identified
by the light grey color connector
port. The receivers are easily
identified by the dark grey color
connector port. (Black color for
conductive port.) The package is
designed for auto-insertion and
wave soldering so it is ideal for
high volume production
applications.
Handling and Design
Information
Each part comes with a protective
port cap or plug covering the
optics. These caps/plugs will vary
by port style. When soldering, it
is advisable to leave the protective cap on the unit to keep the
optics clean. Good system
performance requires clean port
optics and cable ferrules to avoid
obstructing the optical path.
Clean compressed air often is
sufficient to remove particles of
dirt; methanol on a cotton swab
also works well.
Recommended Chemicals for
Cleaning/Degreasing
HFBR-0400 Products
Alcohols: methyl, isopropyl,
isobutyl. Aliphatics: hexane,
heptane, Other: soap solution,
naphtha.
Do not use partially halogenated
hydrocarbons such as 1,1.1
trichloroethane, ketones such as
MEK, acetone, chloroform, ethyl
acetate, methylene dichloride,
phenol, methylene chloride, or
N-methylpyrolldone. Also, HP
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.

In addition to the various port
styles available for the HFBR0400 series products, there are
also several extra options that
can be ordered. To order an
option, simply place the corresponding option number at the
end of the part number. For
instance, a metal-port option SMA
receiver would be HFBR-2406M.
You can add any number of
options in series at the end of a
part number. Please contact your

Typical Link Data
HFBR-0400 Series
Description
The following technical data is
taken from 4 popular links using
the HFBR-0400 series: the 5 MBd
link, Ethernet 20 MBd link,
Token Ring 32 MBd link, and the
155 MBd link. The data given
corresponds to transceiver solutions combining the HFBR-0400
series components and various
recommended transceiver design
circuits using off-the-shelf
electrical components. This data
is meant to be regarded as an
example of typical link performance for a given design and does
not call out any link limitations.
Please refer to the appropriate
application note given for each
link to obtain more information.
