The HFBR-5106/-5106T are 1300
nm products with optical
performance compliant with the
100VG-AnyLAN PMD developed
by IEEE 802.12. These
transceivers are suitable for link
lengths up to 2 km.
Alternative 800 nm,
Lower Cost 500 m
Desktop Links
The HFBR-5107 is a lower cost
800 nm alternative to the HFBR5106 for 100VG-AnyLAN links
from the wiring closet to the
desktop. It complies with the
performance requirements of
802.12 as implemented by
Hewlett-Packard at 800 nm
wavelength. This transceiver will
transfer the full range of
100VG-AnyLan Signals at the
required 1x10–8 Bit Error Rate
over distances up to 500 meters
using 62.5/125 µm multimode
fiber cables. This product is
intended for use in cost sensitive
applications where the benefits of
fiber optic links are important.
Transmitter Sections
The transmitter sections of the
HFBR-5106 utilize 1300 nm
Surface Emitting InGaAsP LEDs
and the HFBR-5107 uses a low
cost 820 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 section of the
HFBR-5106 utilizes InGaAs PIN
photodiodes coupled to a custom
silicon transimpedance preamplifier IC. The HFBR-5107 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.
5965-7785E (4/97)
These PlN/preamplifier combinations are coupled to a custom
quantizer IC which provides the
final pulse shaping for the logic
output and 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.
Package
The overall package concept for
the HP transceivers consists of
the following basic elements; two
optical subassemblies, an
electrical subassembly, and the
housing with integral duplex SC
connector receptacles. This is
illustrated in Figure 1.
The package outline and pinout
are shown in Figures 2 and 3.
The details of this package
outline and pinout are compliant
with the multisource definition of
the 1x9 SIP. The low profile of
the Hewlett- Packard 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 process together
with low cost lens elements which
result in a cost effective
transceiver.
Application Information
The electrical subassembly consists of a high volume multi-layer
printed circuit board on which
the IC chips and various surface
mount passive circuit elements
are attached.
The package includes internal
shields for the electrical and
optical subassemblies to ensure
low EMI and high immunity to
electromagnetic fields.
The outer housing, including the
duplex SC connector receptacle,
is molded of filled non-conductive
plastic to provide mechanical
strength and electrical isolation.
The solder posts of the HewlettPackard design are isolated from
the circuit design of the
transceiver and do not require
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 duplex

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 inline 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 two
transceivers 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 curve represents the remaining OPB at any
link length, which is available for
overcoming non-fiber cable
related losses.

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 shortest symbol time. Data
rate (bits/sec) is the symbol rate
divided by the encoding factor
used to encode the data
(symbols/bit).
Table 1 lists the hub control
signals defined in IEEE 802.12,
section 18.5.4.1. These signal
rates are below 10 MBd but they
are transported with adequate
accuracy for hub access control.
When used in 100VG AnyLAN
100 Mbps applications, the
performance of the 1300 nm
transceiver is guaranteed over the
signaling rate of 10 MBd to
120 MBd to the full conditions
listed in the individual product
specification tables.
Transceiver Jitter
Performance
The Hewlett-Packard 1300 nm
transceivers are designed to
operate per the system interface
jitter specifications listed in Table
27 of section 18.9. of the IEEE
802.12 (100VG-AnyLAN
standards).
The transceivers may be used for
other applications at signaling
rates outside of the 10 MBd to
120 MBd range with some
penalty in the link optical power

The HP 1300 nm transmitters are
allowed to generate the worst
case Active Output jitter shown in
Table 27 of section 18.9 when
driven by circuits optimized for
these link applications. The
Active Output Specifications of
the 100VG-AnyLAN standard are
met by the HFBR-5106.
The HP 1300 nm receivers
tolerate the worst case input

systematic jitter shown in
Table 27 of Section 18.9. The
Active Input Specification of the
IEEE 802.12 100VG-AnyLAN
standard are met by the
HBFR-5106.
The jitter specifications stated in
the 1300 nm transceiver
specification tables are derived
from the values in Table 27 of
section 18.9 of the IEEE 802.12
specification. They represent the
worst case jitter contributions
from the transceiver meeting the
overall system jitter in Annex E.
In practice the typical jitter
contribution of the HP transceivers is well below these maximum
allowed values.
Recommended Handling
Precautions
It is advised 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-510X series of

Solder and Wash Process
Compatibility
The transceivers are delivered
with a protective process plug
inserted into the duplex SC
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 soldering
processes.

The transceiver is packaged in a
shipping container designed to
protect it from mechanical and
ESD damage during shipment or
storage.

that a contiguous ground plane
be provided in the circuit board
directly under the transceiver to
provide a low inductance ground

recommendation is in keeping
with good high frequency board
layout practices.
Board Layout – Hole
Pattern
This 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 Y14.5N
compliant dimensioning to be
used as a guide in the mechanical
layout of your circuit board.
Board Layout – Art Work
The Applications Engineering
group has developed Gerber file
artwork for a multilayered printed
circuit board layout incorporating
the above recommendations.
Contact your local Hewlett-
156
Packard sales representative for
details.
Board Layout –
Mechanical
For applications 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
mm for sufficient clearance to
install the ST connector.
Please refer to Figure 8a for a
mechanical layout detailing the
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 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.

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 supplied to
differential ECL circuitry. This
circuitry maintains a nearly constant
current 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 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 electrical rise and fall times
are measured between 20% and 80%
levels with the output connected to
VCC –2 V through 50 Ω.
8. Random Jitter contributed by the
receiver is specified with a 120 MBd
(60 MHz square-wave) input signal.
The input optical power level is at
maximum "PIN MIN. (W)".
9. These optical power values are
measured with the following
conditions:
• At the Beginning of Life (BOL). The
actual FDDI specification is 1.5 dB
lower power at the End of Life for
the equipment. The definition of
Beginning of Life (BOL) to the End
of Live (EOL) optical power
degradation is assumed to be 1.0 dB
per the industry convention for
1300 nm LEDs. The actual
degradation observed in normal
commercial environments is
considerably less than this amount
with Hewlett-Packard’s 1300 nm
LED products.
• At the end of one meter of noted
fiber with cladding modes removed.
• Over the specified operating voltage
and temperature ranges.
• (12.5 MHz square-wave) input
signal. The average power value can
be converted to a peak power value
by adding 3 dB. Higher output
optical power transmitters are
available upon special request.
10. The same comments of Note 9 apply
except that industry convention for
800 nm LED BOL to EOL aging is 3
dB. This value for Output Optical
Power provides a minimum of 7.5 dB
optical power budget at the EOL,
which provides at least 500 meter link
lengths with margin left over for
overcoming normal passive losses,
such as in-line connectors in the cable
plant. The actual degradation observed
in normal commercial environments is
considerably less than this amount
with Hewlett-Packard 800 nm LED
products.
11. The transmitter provides compliance
with 802.12. An Output Optical Power
level of <–45 dBm average in
response to a logic "0" input. This
specification applies to either
62.5/125 µm or 50/125 µm fiber
cables.
12. This parameter complies with 802.12.
13. The optical rise and fall times are
measured from 10% to 90% when the
transmitter is driven by a 12.5 MHz
square-wave input signal.
14. The optical rise and fall times are
measured from 10% to 90% when the
transmitter is driven by a 12.5 MHz
square-wave input signal.
15. Random Jitter contributed by the
transmitter is specified with a 60 MBd
square-wave 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 10-8.
• At the Beginning of Life (BOL).
• Over the specified operating
temperature and voltage ranges.
• Receiver data window opening timewidth is 2.2 ns or greater and
centered at mid-symbol. This worst
case window opening time-width is
the minimum allowed eye-opening
presented to the PHY input per
802.12. This minimum window
time-width of 2.2 ns is based upon
the worst case 802.12 Active Input
Interface optical conditions peak-topeak SJ (1.6 ns) and RJ (0.77 ns)
presented to the receiver.
To test a receiver with the worst
case 802.12 Active Input Jitter
condition requires exacting control
over SJ and RJ jitter components.
This is difficult to implement with
production test equipment. The
receiver can be equivalently tested
to the worst case 802.12 input jitter
conditions and meet the minimum
output data window time-width of
2.2 ns This is accomplished by
using a nearly ideal input optical
signal (No DCD, insignificant DDJ
and RJ) and measuring for a wider
window time-width of 4.0 ns. This is
possible due to the cumulative addition of jitter components through
their superposition. (SJ is directly
additive and RJ components are rms
additive). Specifically, when a
nearly ideal input optical test signal
is used and the maximum receiver
peak-to-peak jitter contributions of
SJ (X.Xns), and RJ (X.Xns) exist,
the minimum window time-width
becomes 4.4 ns. This wider window
time-width of 4.4 ns guarantees the
802.12 time-width of 2.2 ns under
worst case input jitter conditions to
the Hewlett-Packard receiver.
• Transmitter operating with a 120
MBd (60 MHz square-wave), input
signal to simulate any cross-talk
present between the transmitter and
receiver sections of the transceiver.
16a. All conditions of Note 16 apply except
that the BER requirement is tightened
to 1x10-8 and the minimum window
time-width test condition is adjusted to
5.2 ns to reflect the HFBR-5107 transmitter contributed jitter values per the
specification table.
17. All conditions of Note 16 apply except
that the measurement is made at the
center of the symbol with no window
time-width.
17a. All conditions of Note 17 apply
except that the BER requirement is
tightened to 1x10-8.
18. This value is measured during the
transition from low to high levels of
input optical power.
19. The high_light (Signal Detect) output
shall be asserted within 100 µs after a
step increase of the Input Optical
Power. The step will be from a low
Input Optical Power ≤ –45 dBm, into
the range between greater than Pm
and (Pm + 4 dB). Pm is the relevant
163
minimum allowed input average optical
power for the PMD at the AI as defined
in Figure 10. (The input optical power
is averaged over a period of 1 µs or
more).
20. The high_light (Signal Detect) output
shall be asserted within 100 µs after a
step increase of the Input Optical
Power. The step will be from a low
Input Optical Power ≤ –45 dBm, into
the range between greater than Pm
and (Pm + 4 dB). Pm is the relevant
minimum allowed input average
optical power for the PMD at the AI as
defined in Figure 10. (The input
optical power is averaged over a
period of 1 µs or more).
21. This value is measured during the
transition from high to low levels of
input optical power. The maximum
164
value will occur when the input optical
power is –45 dBm average or when the
input optical power yields a BER of 102 or better, whichever power is higher.
22. The low_light (Signal Detect) output
shall be deasserted within 350 µs after
valid IEEE 802.12 optical signals cease
to be present at the AI and the input
average optical power at AI has fallen
monitonically from a level between (Pm
+4 dB) and Pm to a level below –45
dBm and remain below –45 dBm (see
Figure 10). (The input optical power is
averaged over a period of 1 µs or
more.)
22. The low_light (Signal Detect) output
shall be deasserted within 350 µs after
valid IEEE 802.12 optical signals cease
to be present at the AI and the input
average optical power at AI, has fallen
monitonically from a level between
(Pm +4 dB) and Pm to a level below –
45 dBm and remain below –45 dBm
(see Figure 10). (The input optical
power is averaged over a period of 1
µs or more.)
23. Systematic Jitter (SJ) contributed by
the 800 and 1300 nm transmitter is a
combination of Duty Cycle Distortion
(DCD) and Data Dependent Jitter
(DDJ).
24. Random Jitter contributed by the 800
and 1300 nm transmitter is specified
with an IDLE Line State, 125 MBd
(62.5 MHz square-wave), input signal.
