Transmitter Sections
The transmitter section of the
AFBR-5803Z and AFBR-5805Z
series utilize 1300 nm Surface
Emitting 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 differential
PECL logic signals, ECL
referenced (shifted) to a +3.3 V
or +5 V supply, into an analog
LED drive current.
Receiver Sections
The receiver sections of the
AFBR-5803Z and AFBR-5805Z
series utilize InGaAs PIN
photodiodes 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 +3.3 V or +5 V
power supply.
Package
The overall package concept
for the Agilent transceivers
consists of the following basic
elements; two optical
subassemblies, an electrical
subassembly and the housing
as illustrated in Figure 1 and
Figure 1a.
The package outline drawings
and pin out are shown in
Figures 2, 2a and 3. The
details of this package outline
and pin out are compliant
with the multisource definition
of the 1 x 9 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 outer housing including
the duplex SC connector
receptacle or the duplex ST
ports is molded of filled
nonconductive plastic to
provide mechanical strength
and electrical isolation. The
solder posts of the Agilent
design are isolated from the
circuit design of the
transceiver and do not require
connection to a ground plane
on the circuit board.
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 duplex or simplex SC or
ST connectored fiber cables.
The electrical subassembly
consists of a high volume
multilayer printed circuit
board on which the IC chips
and various surface-mounted
passive circuit elements are
attached.
The package includes internal
shields for the electrical and
optical subassemblies to ensure
low EMI emissions and high
immunity to external EMI
fields.

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
transceiver 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 nonfiber cable related losses.
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 Agilent 1300 nm LEDs will
experience less than 1 dB of
aging over normal commercial

specifications 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

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.

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

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 Agilent
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,
two 0.5" holes 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 1 x 9 transceiver
emissions will be identical to
the duplex SC 1 x 9

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in
isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting values
of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for extended
periods can adversely affect device reliability.

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 W
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 W 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 W
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 W.
8. Duty Cycle Distortion contributed by the
receiver is measured at the 50% threshold
14
using an IDLE Line State, 125 MBd
(62.5 MHz square-wave), input signal. The
input optical power level is -20 dBm
average. See Application Information Transceiver Jitter Section for further
information.
9. Data Dependent Jitter contributed by
the receiver is specified with the FDDI DDJ
test pattern described in the FDDI PMD
Annex A.5. The input optical power level is 20 dBm average. See Application Information - Transceiver Jitter Section for further
information.
10. Random Jitter contributed by the receiver is
specified with an IDLE Line State,
125 MBd (62.5 MHz square-wave), input
signal. The input optical power level is at
maximum “PIN Min. (W)”. See Application
Information - Transceiver Jitter Section for
further information.
11. 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
Agilent’s 1300 nm LED products is
< 1 dB, as specified in this data sheet.
• Over the specified operating voltage and
temperature ranges.
•
With HALT Line State, (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.
12. 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 HALT Line State
(12.5 MHz square-wave) signal, the average
optical power is measured. The data “1”
peak power is then calculated by adding 3
dB 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.
13. The transmitter provides compliance with
the need for Transmit_Disable commands
from the FDDI SMT layer by providing 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.
14. This parameter complies with the FDDI PMD
requirements for the trade-offs between
center wavelength, spectral width, and rise/
fall times shown in Figure 9.
15. This parameter complies with the optical
pulse envelope from the FDDI PMD shown
in Figure 10. The optical rise and fall times
are measured from 10% to 90% when the
transmitter is driven by the FDDI HALT Line
State (12.5 MHz square-wave) input signal.
16. Duty Cycle Distortion contributed by the
transmitter is measured at a 50% threshold
using an IDLE Line State, 125 MBd
(62.5 MHz square-wave), input signal. See
Application Information - Transceiver Jitter
Performance Section of this data sheet for
further details.
17. Data Dependent Jitter contributed by the
transmitter is specified with the FDDI test
pattern described in FDDI PMD Annex A.5.
See Application Information - Transceiver
Jitter Performance Section of this data
sheet for further details.
18. Random Jitter contributed by the
transmitter is specified with an IDLE Line
State, 125 MBd (62.5 MHz square-wave),
input signal. See Application Information Transceiver Jitter Performance Section of
this data sheet for further details.
19. 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 2.5
x 10-10.
• At the Beginning of Life (BOL)
• Over the specified operating temperature
and voltage ranges
• Input symbol pattern is the FDDI test
pattern defined in FDDI PMD Annex A.5
with 4B/5B NRZI encoded data that
contains a duty cycle base-line wander
effect of 50 kHz. This sequence causes a
near worst case condition for intersymbol interference.
• Receiver data window time-width is
2.13 ns or greater and centered at
mid-symbol. This worst case window
time-width is the minimum allowed
eye-opening presented to the FDDI PHY
PM._Data indication input (PHY input)
per the example in FDDI PMD Annex E.
This minimum window time-width of 2.13
ns is based upon the worst case FDDI
PMD Active Input Interface optical
conditions for peak-to-peak DCD (1.0 ns),
DDJ (1.2 ns) and RJ (0.76 ns) presented
to the receiver.
To test a receiver with the worst case FDDI
PMD Active Input jitter condition requires
exacting control over DCD, DDJ and RJ jitter
components that is difficult to implement

with production test equipment. The
receiver can be equivalently tested to the
worst case FDDI PMD input jitter conditions
and meet the minimum output data window
time-width of 2.13 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
4.6 ns. This is possible due to the cumulative
effect of jitter components through their
superposition (DCD and DDJ are 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 DCD (0.4 ns), DDJ (1.0 ns),
and RJ (2.14 ns) exist, the minimum window
time-width becomes 8.0 ns -0.4 ns - 1.0 ns 2.14 ns = 4.46 ns, or conservatively 4.6 ns.
This wider window time-width of 4.6 ns
guarantees the FDDI PMD Annex E
minimum window time-width of 2.13 ns
under worst case input jitter conditions to
the Agilent receiver.
• Transmitter operating with an IDLE Line
State pattern, 125 MBd (62.5 MHz
square-wave), input signal to simulate
any cross-talk present between the
transmitter and receiver sections of the
transceiver.
All conditions of Note 19 apply except that
the measurement is made at the center of
the symbol with no window time-width.
This value is measured during the transition
from low to high levels of input optical
power.
The 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 PA, and
-14 dBm. The BER of the receiver output will
be 10-2 or better during the time, LS_Max
(15 µs) after Signal Detect has been
asserted. See Figure 12 for more
information.
This value is measured during the transition
from high to low levels of input optical
power. The maximum value will occur when
the input optical power is either -45 dBm
average or when the input optical power
yields a BER of 10-2 or larger, whichever
power is higher.
Signal detect output shall be de-asserted
within 350 µs after a step decrease in the
Input Optical Power from a level which is
the lower of; -31 dBm or PD + 4 dB (PD is the
power level at which signal detect was deasserted), to a power level of -45 dBm or
less. This step decrease will have occurred
in less than 8 ns. The receiver output will
have a BER of 10-2 or better for a period of
12 µs or until signal detect is de-asserted.
The input data stream is the Quiet Line
State. Also, signal detect will be deasserted within a maximum of 350 µs after
the BER of the receiver output degrades
above 10-2 for an input optical data stream
that decays with a negative ramp function
instead of a step function. See Figure 12 for
more information.
