Description

The HFBR-0400 Series of compo­nents is designed to provide cost
effective, high performance fiber
optic communication links for
information systems and
industrial applications with link
distances of up to 4 kilometers.
With the HFBR-24X6, the 125
MHz analog receiver, data rates
of up to 175 megabaud are
attainable.

Transmitters and receivers are
directly compatible with popular
“industry-standard” connectors:
ST, SMA, SC and FC. They are
completely specified with
multiple fiber sizes; including
50/125 µm, 62.5/125 µm, 100/
140 µm, and 200 µm.

Complete evaluation kits are
available for ST and SMA product
offerings; including transmitter,
receiver, connectored cable, and
technical literature. In addition,
ST and SMA connectored cables
are available for evaluation.

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
local sales office for further
information or browse HP’s fiber
optics home page at http://

Duplex Option

In addition to the standard
options, some HFBR-0400 series
products come in a duplex con­figuration with the transmitter on
the left and the receiver on the
right. This option was designed
for ergonomic and efficient
manufacturing. The following
part numbers are available in the
duplex option:

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.
