Description
The HFBR-5301 and HFBR-5302
Fibre Channel Transceivers from
Agilent Technologies provide the
system designer with products to
implement Fibre Channel designs
for use in multimode fiber (MMF)
applications. These include the
12.5 MB/sec 12-M6-LE-I interface
and the 25 MB/sec 25-M6-LE-I
interface for 1300 nm LED links.
133 MBd
266 MBd
The products are produced in the
new industry standard 1x9 SIP
package style with a duplex SC
connector interface as defined in
the Fiber Channel ANSI FC-PH
standard document.
The HFBR-5301 is a 1300 nm
transceiver specified for use in
133 MBd, 12.5 MB/s, 12-M6-LE-I
Fibre Channel interfaces to either
62.5/125 µm or 50/125 µm
multimode fiber-optic cables.
The HFBR-5302 is a 1300 nm
transceiver specified for use in
266 MBd, 25 MB/s, 25-M6-LE-I
Fibre Channel interfaces to either
62.5/125 µm or 50/125 µm
multimode fiber-optic cables.
Transmitter Sections
The transmitter sections of the
HFBR-5301 and HFBR-5302
utilize 1300 nm InGaAsP LEDs.
These LEDs are packaged in the
optical subassembly portion of
the transmitter section. They are
driven by a custom silicon IC
which converts PECL logic
signals, into an analog LED drive
current.
Receiver Sections
The receiver sections of the
HFBR-5301 and HFBR-5302
utilize InGaAs PIN photo diodes
coupled to a custom silicon
transimpedance preamplifier IC.
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.
Package
The overall package concept for
the Agilent Fibre Channel transceivers consists of three basic
elements; the two optical
subassemblies, an electrical
subassembly and the housing
with integral duplex SC connector interface. This is illustrated in
the block diagram in Figure 1.

The electrical subassembly consists of a high volume multilayer
printed circuit board to which the
IC chips and various surfacemount passive circuit elements
are attached.

The package outline drawing and
pin out are shown in Figures 2
and 3. The details of this package
outline and pin out are compliant
with the multisource definition of
the 1x9 single in-line package
(SIP). The low profile of the
Agilent 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 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
SC connectored fiber cables.

The outer housing, including the
duplex SC connector, is molded
of filled non-conductive plastic to
provide mechanical strength and
electrical isolation. The solder
posts are isolated from the circuit
design of the transceiver, while
they can be connected to a
ground plane on the circuit
board, doing so will have no
impact on circuit performance.

represents the remaining OPB at
any link length, which is available
for overcoming non-fiber cable
losses.
Transceiver Optical Power
Budget vs. 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 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 curves
Agilent LED technology has
produced 1300 nm LED devices
with lower aging characteristics
than normally associated with
these technologies in the
industry. The industry convention
is 1.5 dB aging for 1300 nm
LEDs. The HP LEDs will experience less than 1 dB of aging over
normal commercial equipment
mission life periods. Contact your
Hewlett-Packard sales representative for additional details.
Transceiver Signaling
Operating Rate Range and
BER Performance
For purposes of definition, the
symbol rate (Baud), 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).
The specifications in this data
sheet have all been measured
using the standard Fibre Channel
symbol rates of 133 Mbd or
266 MBd.
The transceivers may be used for
other applications at signaling
rates different than specified in
this data sheet. Depending on the
actual signaling rate, there may
be some differences in optical

These parameters are reflected in
the specified performance of the
transceiver in this data sheet.
This same model has been used
extensively in the ANSI and IEEE
committees, including the ANSI
X3T9.5 committee, to establish
the optical performance requirements for various fiber-optic
interface standards. The cable
parameters used come from the

primarily caused by a change of
receiver sensitivity.
These transceivers can also be
used for applications which
require different Bit Error Rate
(BER) performance. Figure 5
illustrates the typical trade-off
between link BER and the
receivers input optical power
level.
Transceiver Jitter
Performance
The Agilent 1300 nm transceivers
are designed to operate per the
system jitter allocations stated in
FC-PH Annex A.4.3 and A.4.4.
The Agilent 1300 nm transmitters
will tolerate the worst case input
electrical jitter allowed, without
violating the worst case output
optical jitter requirements.
The Agilent 1300 nm receivers
will tolerate the worst case input
optical jitter allowed without
violating the worst case output
electrical jitter allowed.
The jitter specifications stated in
the following tables are derived
from the values in FC-PH Annex
A.4.3 and A.4.4. They represent
the worst case jitter contribution
that the transceivers are allowed
to make to the overall system
jitter without violating the
allowed allocation. In practice,
the typical contribution of the
Agilent transceivers is below
these maximum allowed amounts.
Recommended Handling
Precautions
Agilent recommends that normal
static precautions be taken in
handling and assembly of these
transceivers to prevent damage
and/or degradation which may be
induced by electrostatic

and hand solder processes.
discharge (ESD). These transceivers are certified as MIL-STD883C Method 3015.4 Class 2
devices.
Shipping Container
The transceiver is packaged in a
shipping container designed to
protect it from mechanical and
ESD damage during shipment or
storage.
Care should be used to avoid
shorting the receiver data or
signal detect outputs directly to
ground.
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.

Board Layout – Decoupling
Circuit and Ground Planes
You should take care in the layout

optimum performance from these
transceivers. Figure 6 provides a
good example of a schematic for
a power supply decoupling circuit
that works well with these parts.

Board Layout - Hole Pattern
The Agilent transceiver complies
with the circuit board “Common
Transceiver Footprint” hole
pattern defined in the original
multisource announcement for
the 1x9 pin package style. This
drawing is reproduced in Figure 7
with the addition of ANSI Y14.5M
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
art work for a multilayer printed
circuit board layout incorporating
the recommendations above.
Contact your local Agilent sales
representative for details.
Regulatory Compliance
These transceiver products are
intended to enable 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.
Electromagnetic Interference
(EMI)
Most equipment designs utilizing
these high-speed transceivers
from Agilent will need to meet the
requirements of the FCC in the
United States, CENELEC
EN55022 (CISPR 22) in Europe
and VCCI in Japan.
The HFBR-5301 and HFBR-5302
are suitable for use in designs
ranging from a single transceiver
in a desktop computer to large
quantities of transceivers in a
hub, switch or concentrator.

–A–
The first case is during handling
of the transceiver prior to mounting it on the circuit board. You
should 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 transceiver 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.
Immunity
Equipment utilizing these transceivers will be subject to radiofrequency electromagnetic fields
in some environments. These
transceivers have a high immunity
to such fields (see AN1075,
“Testing and Measuring Electromagnetic Compatibility Performance of the HFBR-510X/520X
Fiber-Optic Transceivers,” 59633358E).
Transceiver Reliability and
Performance Qualification

The 1x9 transceivers have passed
Agilent reliability and

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. When component testing these
products do not short the receiver
data or signal detect outputs directly
to ground to avoid damage to the
part.
3. The outputs are terminated with 50
Ω connected to VCC - 2 V.
4. 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.
5. These optical power values are
measured as follows:
• 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 Agilent’s
1300 nm LED products is < 1 dB
as specified in this data sheet.
• 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.
6. 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 12.5 MHz
square-wave 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.
This parameter complies with the
requirements for the tradeoffs
between center wave-length, spectral
width, and rise/fall times shown in
Figure 8.
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. This parameter complies with
the requirements for the tradeoffs
between center wavelength, spectral
width, and rise/fall times shown in
Figure 8.
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.
Deterministic Jitter is defined as the
combination of Duty Cycle
Distortion and Data Dependent
Jitter. Deterministic Jitter is
measured with a test pattern
consisting of repeating K28.5
(00111110101100000101) data
bytes and evaluated per the method
in FC-PH Annex A.4.3.
Random Jitter is specified with a
sequence of K28.7 (square wave of
alternating 5 ones and 5 zeros) data
bytes and evaluated at a Bit Error
Ratio (BER) of 1 x 10 -12 per the
method in FC-PH Annex A.4.4.
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
specified to provide output data with
a Bit Error Rate (BER) better than
or equal to 1 x 10-12 .
• At the Beginning of Life (BOL)
• Over the specified operating temperature and voltage ranges.
• Input is a 266 MBd, 2 7 - 1
psuedorandom data pattern.
• Receiver data window time-width
is ± 0.94 ns or greater and
centered at mid-symbol. This data
window time width is calculated to
simulate the effect of worst case
input jitter per FC-PH Annex J
and clock recovery sampling
position in order to insure good
operation with the various FC-0
receiver circuits.
• The integral transmitter is operating with a 266 MBd, 133 MHz
square-wave, input signal to simulate any cross-talk present
between the transmitter and
receiver sections of the
transceiver.
• The maximum total jitter added by
the receiver and the maximum
total jitter presented to the clock
recovery circuit comply with the
maximum limits listed in Annex J,
but the allocations of the Rx
added jitter between deterministic
jitter and random jitter are
different than in Annex J.
11a. Same as Note 11 except:
• The receiver input signal is a 133
MBd, 27 - 1 psuedorandom data
patter.
• The integral transmitter is operating with a 133 MBd, 66.5 MHz
square wave.
• The receiver data window width
is ± 1.73 ns.
• The receiver added jitter maximums and allocations are
identical to the limits listed in
Annex J.
12. All conditions of Note 11 apply
except that the measurement is
made at the center of the symbol
with no window time-width.
12a. All conditions of Note 11a apply
except that the measurement is
made at the center of the symbol
with no window time-width.
13. This value is measured during the
transition from low to high levels of
input optical power.
14. This value is measured during the
transition from high to low levels of
input optical power.
15. These values are measured with the
outputs terminated into 50 Ω
connected to VCC - 2 V and an input
optical power level of -14 dBm
average.
16. 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 supply current, minus
the sum of the products of the
output voltages and currents.
17. These values are measured with
respect to VCC with the output
terminated into 50 Ω connected to
VCC - 2 V.
18. The output rise and fall times are
measured between 20% and 80%
levels with the output connected to
VCC - 2 V through 50 Ω.
19. The Signal Detect output shall be
asserted within 100 µs after a step
increase of the Input Optical Power.
20. Signal detect output shall be deasserted within 350 µs after a step
decrease in the Input Optical Power.
