physical layers for ATM and other
services.
These transceivers are all
supplied in the new industry
standard 1x9 SIP package style
with either a duplex SC or a
duplex ST* connector interface.
ATM 2000 m Backbone Links
The HFBR-5205/-5205T are
1300 nm products with optical
performance compliant with the
SONET STS-3c (OC-3) Physical
Layer Interface Specification. This
physical layer is defined in the
ATM Forum User-Network Interface (UNI) Specification Version
3.0. This document references the
ANSI T1E1.2 specification for the
details of the interface for 2000
meter multimode fiber backbone
links.
Selected versions of these
transceivers may be used to
implement the ATM Forum UNI
Physical Layer Interface at the
155 Mbps/194 MBd rate.
The ATM 100 Mbps/125 MBd
Physical Layer interface is best
implemented with the HFBR-5100
family of FDDI Transceivers
which are specified for use in this
4B/5B encoded physical layer per
the FDDI PMD standard.
ATM 500 m Backbone and
Desktop Links
The HFBR-5204/-5204T are 1300
nm products which are similar to
the HFBR-5205/5205T except
that they are intended to provide
a lower cost SONET OC-3 link to
distances up to 500 meters in
62.5/125 µm multimode fiber
optic cables.
Very Low Cost ATM 300 m
Desktop Links
The HFBR-5203/-5203T are very
low cost 800 nm alternatives to
the HFBR-5204/-5204T for
SONET OC-3 links to distances up
to 300 meters in 62.5/125 µm
multimode fiber optic cables.
Transmitter Sections
The transmitter sections of the
HFBR-5204 and HFBR-5205
series utilize 1300 nm InGaAsP
LEDs and the HFBR-5203 series

uses a low cost 800 nm AlGaAs
LED. These LEDs are packaged in
the optical subassembly portion
of the transmitter section. They
are driven by a custom silicon IC
which converts differential PECL
logic signals, ECL referenced
(shifted) to a +5 Volt supply, into
an analog LED drive current.
Receiver Sections
The receiver sections of the
HFBR-5204 and HFBR-5205
series utilize InGaAs PIN photodiodes coupled to a custom
silicon transimpedance preamplifier IC. The HFBR-5203 series
uses the same preamplifier IC in
conjunction with an inexpensive
silicon PIN photodiode. These are
packaged in the optical subassembly portion of the receiver.
These PIN/preamplifier combinations are coupled to a custom
quantizer IC which provides the
final pulse shaping for the logic
output and the Signal Detect
function. The data output is
differential. The signal detect
output is single-ended. Both data
and signal detect outputs are
PECL compatible, ECL referenced
(shifted) to a +5 volt power
supply.
transceiver design complies with
the maximum height allowed for
the duplex SC connector over the
entire length of the package.
The optical subassemblies utilize
a high volume assembly process
together with low cost lens
elements which result in a cost
effective building block.
The electrical subassembly consists of a high volume multilayer
printed circuit board on which the
IC chips and various surfacemounted passive circuit elements
are attached.
The package includes internal
shields for the electrical and
optical subassemblies to insure
low EMI emissions and high
immunity to external EMI fields.
connection to a ground plane on
the circuit board.
The transceiver is attached to a
printed circuit board with the nine
signal pins and the two solder
posts which exit the bottom of the
housing. The two solder posts
provide the primary mechanical
strength to withstand the loads
imposed on the transceiver by
mating with the duplex or simplex
SC or ST connectored fiber
cables.
Note: The “T” in the product
numbers indicates a transceiver
with a duplex ST connector

without a “T” indicate transceivers
with a duplex SC connector
receptacle.
Application Information
The outer housing including the
duplex SC connector or the
duplex ST ports is molded of filled
non-conductive plastic to provide
mechanical strength and electrical
isolation. The solder posts of the
Hewlett-Packard design are
isolated from the circuit design of
the transceiver and do not require

Hewlett-Packard LED technology
has produced 800 nm LED and
1300 nm LED devices with lower
aging characteristics than
normally associated with these
technologies in the industry. The
industry convention is 3 dB aging
for 800 nm and 1.5 dB aging for
1300 nm LEDs. The 1300 nm HP
LEDs are specified to experience
less than 1 dB of aging over
normal commercial equipment
mission life periods. Contact your
Hewlett-Packard sales representative for additional details.
The following information is
provided to answer some of the
most common questions about
the use of these parts.
Transceiver Optical Power
Budget versus Link Length
Optical Power Budget (OPB) is
the available optical power for a
fiber optic link to accommodate
fiber cable losses plus losses due
to in-line connectors, splices,
optical switches, and to provide
margin for link aging and
unplanned losses due to cable
plant reconfiguration or repair.
Figure 4 illustrates the predicted
OPB associated with the three
transceivers series specified in
this data sheet at the Beginning of
Life (BOL). These curves represent the attenuation and chromatic
plus modal dispersion losses
associated with the 62.5/125 µm
and 50/125 µm fiber cables only.
The area under the curves
represents the remaining OPB at
any link length, which is available
for overcoming non-fiber cable
losses.
Figure 4 was generated for the
1300 nm transceivers with a
Hewlett-Packard fiber optic link
model containing the current
industry conventions for fiber
cable specifications and the draft
ANSI T1E1.2. These optical
parameters are reflected in the
guaranteed performance of the
transceiver specifications in this
data sheet. This same model has
been used extensively in the ANSI
and IEEE committees, including
the ANSI T1E1.2 committee, to
establish the optical performance
requirements for various fiber
The HFBR-5203 series 800 nm
transceiver curve in Figure 4 was
generated based on extensive
empirical test data of the 800 nm
transceiver performance. The
curve includes the effect of typical
fiber attenuation, plus receiver
sensitivity loss due to chromatic
and metal dispersion losses
through the fiber.
Transceiver Signaling
Operating Rate Range and BER
Performance
For purposes of definition, the
symbol (Baud) rate, also called
signaling rate, is the reciprocal of
the symbol time. Data rate (bits/
sec) is the symbol rate divided by
the encoding factor used to
encode the data (symbols/bit).
When used in 155 Mbps SONET
OC-3 applications the performance of the 1300 nm transceivers,
HFBR-5204/5205 is guaranteed

The Hewlett-Packard 1300 nm
transceivers are designed to
operate per the system jitter
allocations stated in Table B1 of
Annex B of the draft ANSI T1E1.2
Revision 3 standard.
The HP 1300 nm transmitters will
tolerate the worst case input
electrical jitter allowed in Annex
B without violating the worst case

The jitter specifications stated in
the following 1300 nm transceiver
specification tables are derived
from the values in Table B1 of
Annex B. They represent the
worst case jitter contribution that
the transceivers are allowed to
make to the overall system jitter
without violating the Annex B
allocation example. In practice,
the typical contribution of the HP
transceivers is well below these
maximum allowed amounts.
Recommended Handling
Precautions
Hewlett-Packard recommends
that normal static precautions be
taken in the handling and
assembly of these transceivers to
prevent damage which may be
induced by electrostatic discharge
(ESD). The HFBR-5200 series of
transceivers meet MIL-STD-883C
Method 3015.4 Class 2 products.
Care should be used to avoid
shorting the receiver data or
signal detect outputs directly to
ground without proper current
limiting impedance.
Solder and Wash Process
Compatibility
The transceivers are delivered
with protective process plugs
inserted into the duplex SC or
duplex ST 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 either industry standard
wave or hand solder processes.

Shipping Container
The transceiver is packaged in a
shipping container designed to
protect it from mechanical and
ESD damage during shipment or
storage.
Board Layout - Decoupling
Circuit and Ground Planes
It is important to take care in the
layout of your circuit board to
achieve optimum performance
from these transceivers. Figure 7
provides a good example of a
schematic for a power supply
decoupling circuit that works well
with these parts. It is further
recommended that a contiguous
ground plane be provided in the
circuit board directly under the
transceiver to provide a low
inductance ground for signal
return current. This recommendation is in keeping with good
high frequency board layout
practices.
Board Layout - Hole Pattern
The Hewlett-Packard transceiver
complies with the circuit board
“Common Transceiver Footprint”
hole pattern defined in the
original multisource
announcement which defined the
1x9 package style. This drawing
is reproduced in Figure 8 with the
addition of ANSI Y14.5M
compliant dimensioning to be
used as a guide in the mechanical
layout of your circuit board.

Contact your local HewlettPackard sales representative for
details.
Board Layout - Mechanical
For applications interested in
providing a choice of either a
duplex SC or a duplex ST connector interface, while utilizing
the same pinout on the printed
circuit board, the ST port needs
to protrude from the chassis
panel a minimum of 9.53 nm for
sufficient clearance to install the
ST connector.
Please refer to Figure 8a for a
mechanical layout detailing the
114
recommended location of the
duplex SC and duplex ST
transceiver packages in relation
to the chassis panel.
Regulatory Compliance
These transceiver products are
intended to enable commercial
system designers to develop
equipment that complies with the
various international regulations
governing certification of Information Technology Equipment.
See the Regulatory Compliance
Table for details. Additional
information is available from your
Hewlett-Packard sales
representative.
Electrostatic Discharge (ESD)
There are two design cases in
which immunity to ESD damage
is important.
The first case is during handling
of the transceiver prior to
mounting it on the circuit board.
It is important to use normal ESD
handling precautions for ESD
sensitive devices. These precautions include using grounded
wrist straps, work benches, and
floor mats in ESD controlled
areas.
The second case to consider is
static discharges to the exterior of
the equipment chassis containing
the transceiver parts. To the
extent that the duplex SC
connector is exposed to the
outside of the equipment chassis
it may be subject to whatever ESD
system level test criteria that the
equipment is intended to meet.

In all well-designed chassis, the
two 0.5" holes required for ST
connectors to protrude through,
will provide 4.6 dB more
shielding than one 1.2" duplex SC
rectangular cutout. Thus, in a
well-designed chassis, the duplex
ST 1x9 transceiver emissions will
be identical to the duplex SC 1x9
transceiver emissions.
Immunity
Equipment utilizing these transceivers will be subject to radiofrequency electromagnetic fields
in some environments. These
transceivers have a high immunity
to such fields.

Notes:
1. This is the maximum voltage that
can be applied across the Differential
Transmitter Data Inputs to prevent
damage to the input ESD protection
circuit.
2. The outputs are terminated with
50 Ω connected to VCC -2 V.
3. The power supply current needed to
operate the transmitter is provided
to differential ECL circuitry. This
circuitry maintains a nearly constant current flow from the power
supply. Constant current operation
helps to prevent unwanted electrical
noise from being generated and
conducted or emitted to neighboring
circuitry.
4. This value is measured with the
outputs terminated into 50 Ω
connected to VCC -2 V and an Input
Optical Power level of -14 dBm
average.
5. The power dissipation value is the
power dissipated in the receiver
itself. Power dissipation is calculated as the sum of the products of
supply voltage and currents, minus
124
the sum of the products of the
output voltages and currents.
6. This value is measured with respect
to VCC with the output terminated
into 50 Ω connected to VCC -2 V.
7. The output rise and fall times are
measured between 20% and 80%
levels with the output connected to
VCC -2 V through 50 Ω.
8. These optical power values are
measured with the following
conditions:
• The Beginning of Life (BOL) to
the End of Life (EOL) optical
power degradation is typically
1.5 dB per the industry convention for long wavelength LEDs.
The actual degradation observed
in Hewlett-Packard’s 1300 nm
LED products is <1 dB, as
specified in this datasheet.
• Over the specified operating
voltage and temperature ranges.
• With 25 MBd (12.5 MHz squarewave) input signal.
• At the end of one meter of noted
optical fiber with cladding modes
removed.
The average power value can be
converted to a peak power value
by adding 3 dB. Higher output
optical power transmitters are
available on special request.
9. The same comments of note 9 apply
except that industry convention for
short wavelength LED (800 nm)
aging is 3 dB. This value for Output
Optical Power will provide a
minimum 6 dB optical power budget
at the EOL, which will provide at
least 150 meter link lengths with
margin left over for overcoming
normal passive losses, such as inline connectors, in the cable plant.
The actual degradation observed in
normal commercial environments
will be considerably less than this
amount with Hewlett-Packard’s 800
nm LED products. Please consult
with your local HP sales representative for further details.
10. The Extinction Ratio is a measure of
the modulation depth of the optical
signal. The data “0” output optical
power is compared to the data “1”
peak output optical power and
expressed as a percentage. With the
transmitter driven by a 25 MBd
(12.5 MHz square-wave) input
signal, the average optical power is
measured. The data “1” peak power
is then calculated by adding 3dB to
the measured average optical power.
The data “0” output optical power is
found by measuring the optical
power when the transmitter is
driven by a logic “0” input. The
extinction ratio is the ratio of the
optical power at the “0” level
compared to the optical power at the
“1” level expressed as a percentage
or in decibels.
11. The transmitter will provide this low
level of Output Optical Power when
driven by a logic “0” input. This can
be useful in link troubleshooting.
12. The relationship between Full Width
Half Maximum and RMS values for
Spectral Width is derived from the
assumption of a Gaussian shaped
spectrum which results in a 2.35 X
RMS = FWHM relationship.
13. The optical rise and fall times are
measured from 10% to 90% when
the transmitter is driven by a 25
MBd (12.5 MHz square-wave) input
signal. The ANSI T1E1.2 committee
has designated the possibility of
defining an eye pattern mask for the
transmitter optical output as an
item for further study. HP will
incorporate this requirement into
the specifications for these products
if it is defined. The HFBR-5204 and
HFBR-5205 products typically
comply with the template requirements of CCITT (now ITU-T) G.957
Section 3.2.5, Figure 2 for the STM1 rate, excluding the optical receiver
filter normally associated with
single mode fiber measurements
which is the likely source for the
ANSI T1E1.2 committee to follow in
this matter.
14. Systematic Jitter contributed by the
transmitter is defined as the combination of Duty Cycle Distortion
and Data Dependent Jitter.
Systematic Jitter is measured at
50% threshold using a 155.52 MBd
(77.5 MHz square-wave), 27 - 1
psuedorandom data pattern input
signal.
15. Random Jitter contributed by the
transmitter is specified with a
155.52 MBd (77.5 MHz squarewave) input signal.
16. This specification is intended to
indicate the performance of the
receiver section of the transceiver
when Input Optical Power signal
characteristics are present per the
following definitions. The Input
Optical Power dynamic range from
the minimum level (with a window
time-width) to the maximum level is
the range over which the receiver is
guaranteed to provide output data
with a Bit Error Ratio (BER) better
than or equal to 1 x 10-10.
• At the Beginning of Life (BOL)
• Over the specified operating
temperature and voltage ranges
• Input is a 155.52 MBd, 223 - 1
PRBS data pattern with 72 “1”s
and 72 “0”s inserted per the
CCITT (now ITU-T) recommendation G.958 Appendix I.
• Receiver data window time-width
is 1.23 ns or greater for the clock
recovery circuit to operate in. The
actual test data window timewidth is set to simulate the effect
of worst case optical input jitter
based on the transmitter jitter
values from the specification
tables. The test window timewidths are as follows: HFBR-5203
is 4.4ns, HFBR-5205 and HFBR5204 are 3.32 ns.
• Transmitter operating with a
155.52 MBd, 77.5 MHz squarewave, input signal to simulate
any cross-talk present between
the transmitter and receiver
sections of the transceiver.
17. All conditions of Note 16 apply except
that the measurement is made at
the center of the symbol with no
window time-width.
18. Systematic Jitter contributed by the
receiver is defined as the combination of Duty Cycle Distortion and
Data Dependent Jitter. Systematic
Jitter is measured at 50% threshold
using a 155.52 MBd (77.5 MHz
square-wave), 27 - 1 psuedorandom
data pattern input signal.
19. Random Jitter contributed by the
receiver is specified with a 155.52
MBd (77.5 MHz square-wave) input
signal.
20. This value is measured during the
transition from low to high levels of
input optical power.
21. This value is measured during the
transition from high to low levels of
input optical power.
22. The Signal Detect output shall be
asserted within 100 µs after a step
increase of the Input Optical Power.
23. Signal detect output shall be deasserted within 350 µs after a step
decrease in the Input Optical Power.
24. The HFBR-5205 transceiver
complies with the requirements for
the tradeoffs between center wavelength, spectral width, and rise/fall
times shown in Figure 9. This figure
is derived from the FDDI PMD
standard (ISO/IEC 9314-3 : 1990
and ANSI X3.166 - 1990) per the
description in ANSI T1E1.2 Revision
3. The interpretation of this figure is
that values of Center Wavelength
and Spectral Width must lie along
the appropriate Optical Rise/Fall
Time curve.
