Functional Description
Receiver Section
Transmitter Section
Design
The receiver section for the
HFCT-5760xxx contains an
InGaAs/InP photo detector and
a preamplifier mounted in an
optical subassembly. This optical
subassembly is coupled to a
postamplifier/decision circuit on
a circuit board.
Design
A schematic diagram for the
transceiver is shown in Figure 1.
The HFCT-5760xxx incorporates
an FP laser as its optical source.
All part numbers have been
designed to be compliant with
IEC 825 eye safety requirements
under any single fault condition
and CDRH under normal
operating conditions. The
optical output is controlled by a
custom IC that detects the laser
output via the monitor
photodiode. This IC provides
both dc and ac current drive to
the laser to ensure correct
modulation, eye diagram and
extinction ratio over
temperature, supply voltage and
operating life.
The postamplifier is ac coupled
to the preamplifier. The
coupling capacitors are large
enough to pass the SONET/SDH
test pattern at 155 Mb/s without
significant distortion or
performance penalty. If a lower
signal rate, or a code which has
significantly more low frequency
content is used, sensitivity, jitter
and pulse distortion could be
degraded.
There is a filter function which
limits the bandwidth of the
preamp output signal. The filter
is designed to bandlimit the
preamp output noise and thus
improve the receiver sensitivity.
Loss of Signal
The Loss of Signal (LOS) output
indicates that the optical input
signal to the receiver does not
meet the minimum detectable
level for compliant signals.
When LOS is high it indicates
loss of signal. When LOS is low
it indicates normal operation.
The Loss of Signal thresholds are
set to indicate a definite optical
fault has occurred (eg.,
disconnected or broken fiber
connection to receiver, failed
transmitter).
Tx Disable
The HFCT-5760xxx accepts a
transmit disable control signal
input which shuts down the
transmitter. A high signal
implements this function while a
low signal allows normal laser
operation. In the event of a fault
(eg., eye safety circuit
activated), cycling this control
signal resets the module. The Tx
Disable control should be
actuated upon initialization of
the module.
Tx Fault
The HFCT-5760xxx module
features a transmit fault control
signal output which when high
indicates a laser transmit fault
has occurred and when low
indicates normal laser
operation. A transmitter fault
condition can be caused by
deviations from the
recommended module operating
conditions or by violation of eye
safety conditions. A fault is
cleared by cycling the Tx Disable
control input.

Module Description
The transceiver meets the Small
Form Pluggable (SFP) industry
standard package utilizing an
integral LC-Duplex optical
interface connector. The hotpluggable capability of the SFP
package allows the module to be
installed at any time - with the
host system operating and online. This allows for system
configuration changes or
maintenance without system
down time. The HFCT-5760xxx
uses a reliable 1300 nm FP laser
source and requires a 3.3 V dc
power supply for optimal design.
Module Diagrams
Figure 1 illustrates the major
functional components of the
HFCT-5760xxx. The connection
diagram of the module is shown
in Figure 4. Figure 2 depicts the
external configuration of the
module. Figure 3 depicts the
MSA recommended power
supply filter.

Installation
The HFCT-5760xxx can be
installed in or removed from any
Multisource Agreement (MSA) compliant Small Form Pluggable
port regardless of whether the
host equipment is operating or
not. The module is simply
inserted, electrical interface
first, under finger pressure.
Controlled hot-plugging is
ensured by design and by 3stage pin sequencing at the
electrical interface. The module
housing makes initial contact
with the host board EMI shield
mitigating potential damage due
to Electro-Static Discharge
(ESD). The 3-stage pin contact
sequencing involves (1) Ground,
(2) Power, and then (3) Signal
pins, making contact with the
host board surface mount
connector in that order.

Notes:
1. TX Fault is an open collector/drain output which should be pulled up externally with a 4.7K – 10 KW resistor on the host board to a supply < Vcc + 0.3
V. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V.
2. TX disable input is used to shut down the laser output per the state table below with an external 4.7-10 KW4 pull-up resistor.
Low (0 – 0.8 V):
Transmitter on
Between (0.8 V and 2.0 V): Undefined
High (2.0 – 3.465 V):
Transmitter Disabled
Open:
Transmitter Disabled
3. Mod-Def0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10 KW resistor on the host board to a supply less than VccT
(0.3 V or VccR + 0.3 V.
Mod-Def 0 is grounded by the module to indicate that the module is present
Mod-Def 1 is clock line of two wire serial interface for optional serial ID
Mod-Def 2 is data line of two wire serial interface for optional serial ID
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7K – 10 KW resistor on the host board to a supply
< VccT,R + 0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard
in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V. Please see later section for LOS timing.
5. VeeR and VeeT may be internally connected within the SFP module
6. RD-/+: These are the differential receiver outputs. They are ac coupled 100 W differential lines which should be terminated with 100 W differential at
the user SERDES. The ac coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be
between 370 and 2000 mV differential (185 – 1000 mV single ended) when properly terminated.
7. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.1 – 3.5 V at the SFP connector pin. The maximum supply
current is 300 mA.
8. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100 W differential termination inside the module. The
ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 500 – 2400 mV (250 –
1200 mV single ended).

Regulatory Compliance
Electrostatic Discharge
There are two conditions in
which immunity to ESD damage
is important. The first condition
is during handling of the
transceiver prior to insertion
into the transceiver port. To
protect the transceiver, it is
important to use normal ESD
handling precautions. The ESD
sensitivity of the HFCT-5760xxx
is compatible with typical
industry production
environments. The second
condition is static discharges to
the exterior of the host
equipment chassis after
installation. To the extent that
the duplex LC optical interface
is exposed to the outside of the
host equipment chassis, it may
be subject to system-level ESD
requirements.
The ESD performance of the
HFCT-5760xxx exceeds typical
industry standards.
Immunity
Equipment hosting the HFCT5760xxx modules will be
subjected to radio-frequency
electromagnetic fields in some
environments. These
transceivers have good
immunity to such fields due to
their shielded design.
Eye Safety
These 1300 nm FP laser based
transceivers provide Class 1 eye
safety by design. Agilent has
tested the transceiver design for
compliance with the
requirements listed in Table 3
under normal operating
conditions and under a single
fault condition.
Electromagnetic Interference (EMI)
Most equipment designs utilizing
these high-speed transceivers
from Agilent will be required to
meet the requirements of FCC in
the United States, CENELEC
EN55022 (CISPR 22) in Europe
and VCCI in Japan.
The metal housing and shielded
design of the HFCT-5760xxx
minimize the EMI challenge
facing the host equipment
designer. These transceivers
provide superior EMI
performance. This greatly
assists the designer in the
management of the overall
system EMI performance.

Notes:
1. Cage grounding springs permitted in this
area and may extend full length of
transceiver, 4 places. Grounding springs
may contribute a maximum force of 3.5 N
(Newtons) to the withdrawal force of the
transceiver from the cage.
2. A representative LC connector configuration
is illustrated. Indicated outline defines the
preferred maximum envelope outside of the
cage.
3. Design of actuation method and shape is
optional.

Application Information
The Applications Engineering
Group at Agilent is available to
assist you with technical
understanding and design tradeoffs associated with these
transceivers. You can contact
them through your Agilent sales
representative.
The following information is
provided to answer some of the
most common questions about
the use of parts.
Optical Power Budget
The worst-case Optical Power
Budget (OPB) in dB for a fiberoptic 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 corresponding link penalties.
For proper link performance, all
penalties that affect the link
performance must be accounted
for within the link optical power
budget.
Process Plug
This transceiver is supplied with
a process plug for protection of
the optical port within the LC
connector receptacle. It is made
of a high temperature, molded
sealing material that can
withstand +85 °C.

Recommended Cleaning/Degreasing
Chemicals
Alcohols: methyl, isopropyl,
isobutyl.
Aliphatics: hexane, heptane.
Other: naphtha.
Do not use partially halogenated
hydrocarbons such as 1, 1.1
trichloroethane, ketones such as
MEK, acetone, chloroform, ethyl
acetate, methylene dichloride,
phenol, methylene chloride, or
N-methylpyrolldone. Also,
Agilent does not recommend the
use of cleaners that use
halogenated hydrocarbons
because of their potential
environmental harm.
LC SFP Cleaning Recommendations
In the event of contamination of
the optical ports, the
recommended cleaning process
is the use of forced nitrogen. If
contamination is thought to have
remained, the optical ports can
be cleaned using a NTT
international Cletop stick type
(diam. 1.25 mm) and HFE7100
cleaning fluid.
Evaluation Kit
An evaluation board (HFBR0571) is available via your
Agilent Representative. Full
details can be found in
application note 1237.
Reference Designs
Details to be published shortly.
Caution
There are no user serviceable
parts nor any maintenance
required for the HFCT-5760xxx.
Tampering with or modifying the
performance of the HFCT5760xxx will result in voided
product warranty. It may also
result in improper operation of
the HFCT-5760xxx circuitry, and
possible overstress of the laser
source. Device degradation or
product failure may result.
Connection of the HFCT5760xxx to a non-approved
optical source, operating above
the recommended absolute
maximum conditions or
operating the HFCT-5760xxx in
a manner inconsistent with its
design and function may result
in hazardous radiation exposure
and may be considered an act of
modifying or manufacturing a
laser product. The person(s)
performing such an act are
required by law to recertify and
reidentify the laser product
under the provisions of U.S. 21
CFR (Subchapter J) and the
TUV.
