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.

The HFBR-0400 Series of compo-
nents 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.
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.

• One HFBR-1412 transmitter
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 protec-
tive 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.

• Allows designer to separate the
signal and conductive port
grounds
• Recommended for use in noisy
environments
In addition to the various port
styles available for the HFBR-
0400 series products, there are
also several extra options that
can be ordered. To order an
option, simply place the corre-
sponding 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://

wave solder and aqueous wash
processes
In addition to the standard
options, some HFBR-0400 series
products come in a duplex con-
figuration 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:
• Available on all ST ports
HFBR-5414 (Duplex ST)
HFBR-5414T (Duplex Threaded
ST)

The following example will illus-
trate the technique for selecting
The curves in Figures 3, 4, and 5
are constructed assuming no in-
line splice or any additional
system loss. Should the link
consists of any in-line splices,
these curves can still be used to
calculate link limits provided they
are shifted by the additional
system loss expressed in dB. For
example, Figure 3 indicates that
with 48 mA of transmitter drive
current, a 1.75 km link distance
is achievable with 62.5/125 µm
fiber which has a maximum
attenuation of 4 dB/km. With
2 dB of additional system loss, a
1.25 km link distance is still
achievable.
If resistor R in Figure 2 is
70.4 Ω, a forward current I of
48 mA is applied to the HFBR-
14X4 LED transmitter. With I =
48 mA the HFBR-14X4/24X2
logic link is guaranteed to work
with 62.5/125 µm fiber optic
cable over the entire range of 0
to 1750 meters at a data rate of

HCS . This allows the designer
flexibility in choosing the fiber
size. The HFBR-14XX is designed
to operate with the Hewlett-
Packard HFBR-24XX fiber optic
receivers.
Consistent coupling efficiency is
assured by the double-lens optical
system (Figure 1). Power coupled
into any of the three fiber types
varies less than 5 dB from part to
part at a given drive current and
temperature. Consistent coupling
efficiency reduces receiver
dynamic range requirements
which allows for longer link
lengths.
The HFBR-14XX transmitter’s
high coupling efficiency allows
the emitter to be driven at low
current levels resulting in low
power consumption and increased
reliability of the transmitter. The
HFBR-14X4 high power transmit-
ter is optimized for small size

6. When changing µW to dBm, the optical power is referenced to 1 mW (1000 µW). Optical Power P (dBm) = 10 log P (µW)/1000 µW.
7. Pre-bias is recommended if signal rate >10 MBd, see recommended drive circuit in Figure 11.
8. Pins 2, 6 and 7 are welded to the anode header connection to minimize the thermal resistance from junction to ambient. To further
reduce the thermal resistance, the anode trace should be made as large as is consistent with good RF circuit design.
9. Fiber NA is measured at the end of 2 meters of mode stripped fiber, using the far-field pattern. NA is defined as the sine of the half
angle,determined at 5% of the peak intensity point. When using other manufacturer’s fiber cable, results will vary due to differing
NA values and specification methods.
CAUTION: The small junction sizes inherent to the design of these components increase the components’
susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be
taken in handling and assembly of these components to prevent damage and/or degradation which may be

Figure 11 uses frequency com-
pensation to reduce the typical
rise/fall times of the LED and a
small pre-bias voltage to minimize
propagation delay differences
that cause pulse-width distortion.
The circuit will typically produce
rise/fall times of 3 ns, and a total
jitter including pulse-width dis-
tortion of less than 1 ns. This
circuit is recommended for appli-
cations requiring low edge jitter
or high-speed data transmission
at signal rates of up to 155 MBd.

LED drive currents using the

drive circuits, the reader is
The circuit used to supply current

6. Propagation delay through the system is the result of several sequentially-occurring phenomena. Consequently it is a combination
of data-rate-limiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in
terms of time differentials between delays imposed on falling and rising edges.
7. As the cable length is increased, the propagation delays increase at 5 ns per meter of length. Data rate, as limited by pulse width
distortion, is not affected by increasing cable length if the optical power level at the receiver is maintained.

requirements. Low-cost external

the analog output to logic

tradeoff results in increased optical

Tests were performed on both SMA an ST products with the conductive port option.
The Port Strength test was designed to address the concerns with hand tightening the SMA connector to the fiber optic port. The limit
is set to a level beyond most reasonable hand fastening loading.
3.HP has previously used an air discharge method to measure ESD; results using this method vary with air temperature and humidity.
The direct contact discharge method is perferred due to better repeatability and conformance with IEC procedures. ESD immunity
measured with the air discharge method is generally higher than with the direct contact discharge method.

Technical Data
This feature aids in maintaining
the integrity of the signal ground
if the chassis is exposed to elec-
trical noise. In addition, when the
metal port is in good electrical
contact with a well-grounded
chassis, the metal port provides
additional EMI shielding from
electrically noisy circuits.
HP recommends that the designer
use separate ground paths for the
signal ground and the conductive
metal port ground in order to
minimize the effects of external
coupled noise on receiver
circuitry. If noise is present on
the system chassis, care should
be taken to electrically isolate the
metal port from the chassis.
The Metal Port Option is available
with SMA, ST, Threaded ST
(panel mount) and FC styled port
transmitters and receivers. The
electrical/optical specifications,
the mechanical dimensions, and
the pinouts of the components
with metal ports are identical to
the standard plastic port
The metal port option for the
HFBR-0400 Series gives
designers the ability to have a
metal connector receptacle with
the familiar HFBR-0400 dual in-
line package (DIP). The metal
port option components have an
internal electrical connection
between the metal port and the
four grounding pins, as shown in
the package outline drawing.
Signal ground is separate from
the four grounding pins to give
the flexibility in connecting the
port to signal or chassis ground.
products.
In the case of ESD, the metal port
option does not alleviate the need
for system recovery procedures.
A 15 kV ESD event entering
through the connector port will
not cause catastrophic failure,
but the metal port does not
guarantee error-free performance
during an ESD event.
