Transmitter Section
(HFBR/HFCT-53D3)
The transmitter section of the
HFBR-53D5 consists of an
850 nm Vertical Cavity Surface
Emitting Laser (VCSEL) in an
optical subassembly (OSA),
which mates to the fiber cable.
The HFCT-53D5 incorporates a
1300 nm Fabry-Perot (FP) Laser
designed to meet the Gigabit
Ethernet LX specification. The
OSA is driven by a custom,
silicon bipolar IC which converts
differential PECL logic signals
(ECL referenced to a +5 Volt
supply) into an analog laser diode
drive current.

(See the Regulatory Compliance
Table for transceiver
performance)
Recommended Solder and
Wash Process
The HFBR/HFCT-53D5 is
compatible with industry-
standard wave or hand solder
processes.
The overall equipment design will
determine the certification level.
The transceiver performance is
offered as a figure of merit to
assist the designer in considering
their use in equipment designs.
Immunity
Equipment utilizing these
transceivers will be subject to
radio-frequency electromagnetic
fields in some environments.
These transceivers have good
immunity to such fields due to
their shielded design.
Process plug
This transceiver is supplied with
a process plug (HFBR-5000) for
protection of the optical ports
within the duplex SC connector
receptacle. This process plug
prevents contamination during
wave solder and aqueous rinse as
well as during handling, shipping
and storage. It is made of a high-
temperature, molded sealing
material that can withstand 80°C
and a rinse pressure of 110 lbs
per square inch.
Electrostatic Discharge (ESD)
There are two design cases in
which immunity to ESD damage
is important.
Eye Safety
These laser-based transceivers
are classified as AEL Class I (U.S.
21 CFR(J) and AEL Class 1 per
EN 60825-1 (+A11). They are
eye safe when used within the
data sheet limits per CDRH. They
are also eye safe under normal
operating conditions and under

Optical Power Budget
and Link Penalties
Some fiber-optic transceiver sup-
pliers’ modules include internal
capacitors, with or without 50 Ohm
termination, to couple their Data
and Data-bar lines to the I/O pins
of their module. When designing
to use these type of transceivers
along with Agilent transceivers, it
is important that the interface
circuit can accommodate either
internal or external capacitive
coupling with 50 Ohm termina-
tion components for proper
operation of both transceiver
designs. The internal dc-coupled
design of the
Data Line

Agilent Technologies’ HFBR/
HFCT-53D5 fiber-optic
The worst-case Optical Power
Budget (OPB) in dB for a fiber-
optic link is determined by the
difference between the minimum
transmitter output optical power
(dBm avg) and the lowest
receiver sensitivity (dBm avg).
This OPB provides the necessary
optical signal range to establish a
working fiber-optic link. The OPB
is allocated for the fiber-optic
cable length and the corre-
sponding link penalties. For
proper link performance, all
penalties that affect the link
performance must be accounted
for within the link optical power
budget. The Gigabit Ethernet
IEEE 802.3z standard identifies,
and has modeled, the
transceiver is designed to directly
couple to +5 V PECL signals. The
transmitter inputs are internally
dc-coupled to the laser driver
circuit from the transmitter input
pins (pins 7, 8). There is no
internal, capacitively-coupled 50
Ohm termination resistance
within the transmitter input
section. The transmitter driver
circuit for the laser light source
is a dc-coupled circuit. This
circuit regulates the output
optical power. The regulated light
output will maintain a constant
output optical power provided
the data pattern is reasonably
balanced in duty factor. If the
data duty factor has long, con-
tinuous state times (low or high
data duty factor), then the output
optical power will gradually
change its average output optical
power level to its pre-set value.
HFBR/HFCT-53D5 I/O
connections was done to provide
the designer with the most
flexibility for interfacing to
various types of circuits.

to be eye-safe in the event of a
single fault failure, the transmit-
ter must either maintain normal,
eye-safe operation or be disabled.

penalties to establish the link
length requirements for 62.5/125 µm
and 50/125 µm multimode fiber
usage. In addition, single-mode
fiber with standard 1300 nm
Fabry-Perot lasers have been
modeled and specified. Refer to
the IEEE 802.3z standard and its
supplemental documents that
develop the model, empirical
results and final specifications.
In the HFBR-53D5 there are
three key elements to the laser
driver safety circuitry: a monitor
diode, a window detector circuit,
and direct control of the laser
bias. The window detection
circuit monitors the average
optical power using the monitor
diode. If a fault occurs such that
the transmitter DC regulation
circuit cannot maintain the preset
bias conditions for the laser
emitter within ± 20%, the
As for the receiver section, it is
internally ac-coupled between the
pre-amplifier and the post-
amplifier stages. The actual Data
and Data-bar outputs of the post-
amplifier are dc-coupled to their
respective output pins (pins 2, 3).
Signal Detect is a single-ended,
+5 V PECL output signal that is
dc-coupled to pin 4 of the

As well as complying with the LX
5 km standard, the HFCT-53D5
specification provides additional
margin allowing for a 10 km
Gigabit Ethernet link on single
mode fiber. This is accomplished
by limiting the spectral width and
center wavelength range of the
transmitter while increasing the
output optical power and

be ac-coupled externally to the

only an electrical power reset will

nection between the supporting

One of a circuit board designer’s
foremost concerns is the control
of electromagnetic emissions
from electronic equipment.
Success in controlling generated
Electromagnetic Interference
(EMI) enables the designer to
pass a governmental agency’s
EMI regulatory standard; and
more importantly, it reduces the
possibility of interference to
neighboring equipment. There
are three options available for the
HFBR-53D5 and two options for
the HFCT-53D5 with regard to
EMI shielding which provide the
designer with a means to achieve
good EMI performance. The EMI
performance of an enclosure
using these transceivers is

performance advantage, use
duplex SC fiber-optic connectors
that have low metal content
inside them. This lowers the
ability of the metal fiber-optic
connectors to couple EMI out
through the aperture of the panel
or enclosure.

Notes:
1. The maximum Optical Output Power complies with the IEEE 802.3z specification, and is class 1 laser eye safe.
2. Optical Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the low (“0”) state.
The transmitter is driven with a Gigabit Ethernet 1250 MBd 8B/10B encoded serial data pattern. This Optical Extinction Ratio is expressed in
decibels (dB) by the relationship 10log(Phigh avg/Plow avg).
3. These are unfiltered 20-80% values.
4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 1). The characteristics include rise time, fall time, pulse
overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the receiver sensitivity. These parameters
are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The output optical waveform complies with the requirements
of the eye mask discussed in section 38.6.5 and Fig. 38-2 of IEEE 802.3z.
5. CPR is measured in accordance with EIA/TIA-526-14A as referenced in 802.3z, section 38.6.10.
6. TP refers to the compliance point specified in 802.3z, section 38.2.1.
7. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
8. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The conformance test signal is
conditioned by applying deterministic jitter and intersymbol interference.
9. The stressed receiver jitter is measured using the conformance test signal defined in 802.3z, section 38.6.11 and set to an average optical power 0.5
dB greater than the specified stressed receiver sensitivity.
10. The 3 dB electrical bandwidth of the receiver is measured using the technique outlined in 802.3z, section 38.6.12.

Notes:
1. The maximum Optical Output Power complies with the IEEE 802.3z specification, and is class 1 laser eye safe.
2. Optical Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the
low (“0”) state. The transmitter is driven with a Gigabit Ethernet 1250 MBd 8B/10B encoded serial data pattern. This Optical
Extinction Ratio is expressed in decibels (dB) by the relationship 10log(P
/P
).

3. These are unfiltered 20-80% values.
4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 2). The characteristics include rise time,
fall time, pulse overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the
receiver sensitivity. These parameters are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The
output optical waveform complies with the requirements of the eye mask discussed in section 38.6.5 and Fig. 38-2 of
IEEE 802.3z.
5. TP refers to the compliance point specified in 802.3z, section 38.2.1.
6. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
7. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The

Functional Description
Mounting Pins The mounting pins are provided for transceiver mechanical attachment to the circuit
board. They are embedded in the nonconductive plastic housing and are not connected
to the transceiver internal circuit, nor is there a guaranteed connection to the metallized
housing in the EM and FM versions. They should be soldered into plated-through holes
on the printed circuit board.
