General Features
SFP MSA Compliance
The AFCT-575xZ family of SFP optical transceivers are
The product package is compliant with the SFP MSA with
high performance, cost effective modules for serial op- the LC connector option. The SFP MSA includes specifica-
tical data communications applications ranging from tions for mechanical packaging and performance as well as
155-622 Mbps. They are designed to provide SONET/ dc, ac and control signal timing and performance.
SDH compliant connections for 622 Mbps at short and
intermediate reach links. This includes specifications for
The power supply is 3.3 V dc.
The High Speed I/O (HSIO) signal interface is a Low Voltage
Differential type. It is ac coupled and terminated internally
to the module. The internal termination is a 100 Ohm dif-
ferential load.
the signal coding, optical fiber and connector types, opti-
cal and electrical transmitter characteristics, optical and
electrical receiver characteristics, jitter characteristics, and
compliance testing methodology for the aforementioned.
These transceivers are qualified in accordance with GR-
468-CORE.
Installation
The AFCT-575xZ can be installed in any SFF-8074i compli-
ant Small Form Pluggable (SFP) port regardless of host
equipment operating status. The module is hot-plug-
gable, allowing it to be installed while the host system
is operating and online. Upon insertion, the transceiver
housing makes initial contact with the host board SFP
cage, mitigating potential damage due to electrostatic
discharge (ESD).
The transmitter section of the SR and IR transceivers incor-
porate a 1300nm Fabry Perot (FP) laser. For each device the
receiver section uses an MOVPE grown planar PIN photo-
detector for low dark current and excellent responsivity. A
positive-ECL logic interface simplifies interface to external
circuitry. The receiver section 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.
The AFCT-575xZ family of optical transceivers adds digital
diagnostic monitoring to standard SFP functionality, en-
abling fault isolation, components monitoring and failure
prediction capabilities.

Using the 2-wire serial interface, the AFCT-5755Z provides
real time access to transceiver internal supply voltage and
temperature, transmitter output power, laser bias current
and receiver average input power, allowing a host to pre-
dict system compliance issues. These five parameters are
internally calibrated, per the MSA. New digital diagnostic
information is accessed per SFF-8472 using EEPROM
bytes 0-255 at memory address 0xA2 (A2h).
Receiver Section
The receiver section for the AFCT-575xZ contains an
InGaAs/InP photo detector and a preamplifier mounted
in an optical subassembly. This optical subassembly is
coupled to a post amplifier/decision circuit on a circuit
board. The design of the optical subassembly provides
better than 12 dB Optical Return Loss (ORL).
Connection to the receiver is provided via a LC optical
connector.
The digital diagnostic interface also adds the ability to
disable the transmitter (TX_DISABLE), monitor for Trans-
mitter Faults (TX_FAULT) and monitor for Receiver Loss
of Signal (RX_LOS).
RX_LOS
The receiver section contains a loss of signal (RX_LOS)
circuit to indicate when the optical input signal power
is insufficient for SONET/SDH compliance. A high signal
indicates loss of modulated signal, indicating link failure
such as a broken fiber or a failed transmitter. RX_LOS can
be also be monitored via the two-wire serial (address A2,
byte 110, bit 1).
Contents of the MSA-compliant serial ID memory are
shown in Tables 3 to 7. The SFF-8074i and SFF-8472
specifications are available from the SFF Committee at
http://www.sffcommittee.org.
Predictive Failure Identification
The diagnostic information allows the host system to
identify potential link problems. Once identified, a fail-
over technique can be used to isolate and replace suspect
devices before system uptime is impacted.
Functional Data I/O
Avago’s AFCT-575xZ transceiver is designed to accept
industry standard differential signals. The transceiver pro-
vides an AC-coupled, internally terminated data interface.
Bias resistors and coupling capacitors have been included
within the module to reduce the number of components
required on the customer’s board. Figure 2 illustrates the
recommended interface circuit.
Compliance Prediction
The real-time diagnostic parameters can be monitored to
alert the system when operating limits are exceeded and
compliance cannot be ensured.
Fault Isolation
Digital Diagnostic Interface and Serial Identification
The diagnostic information can allow the host to pinpoint
the location of a link problem and accelerate system ser-
vicing and minimize downtime.
The AFCT-575xZ family complies with the SFF-8074i spec-
ification, which defines the module’s serial identification
protocol to use the 2-wire serial CMOS EEPROM protocol
of the ATMEL AT24C01A or similar. Standard SFP EEPROM
bytes 0-255 are addressed per SFF-8074i at memory ad-
dress 0xA0 (A0h).
Component Monitoring
As part of the host system monitoring, the real time di-
agnostic information can be combined with system level
monitoring to ensure system reliability.
As an enhancement to the conventional SFP interface
defined in SFF-8074i, the AFCT-5755Z is also compliant
to SFF-8472 (the digital diagnostic interface for SFP). This
enhancement adds digital diagnostic monitoring to stan-
dard SFP functionality, enabling failure prediction, fault
isolation, and component monitoring capabilities.

Caution
Electrostatic Discharge (ESD)
The AFCT-575xZ contains no user-serviceable parts. Tam-
pering with or modifying the performance of the AFCT-
575xZ will result in voided product warranty. It may also
result in improper operation of the transceiver circuitry,
and possible over-stress of the laser source. Device deg-
radation or product failure may result. Connection of the
AFCT-575xZ to a non-approved optical source, operating
above the recommended absolute maximum conditions
may be considered an act of modifying or manufacturing
a laser product. The person(s) performing such an act
is required by law to re-certify and re-identify the laser
product under the provisions of U.S. 21 CF.
There are two conditions in which immunity to ESD dam-
age is important:
The first condition is static discharge to the transceiver
during handling such as when the transceiver is inserted
into the transceiver port. To protect the transceiver, it is
important to use normal ESD handling precautions includ-
ing the use of grounded wrist straps, work benches, and
floor mats in ESD controlled areas. The ESD sensitivity of
the AFCT-575xZ is compatible with typical industry pro-
duction environments.
The second condition is static discharge 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 AFCT-575xZ exceeds typical industry
standards. Table 1 documents ESD immunity to both of
these conditions.
Handling Precautions
The AFCT-575xZ can be damaged by current surges or
overvoltage. Power supply transient precautions should
be taken, and normal handling precautions for electro-
static sensitive devices should be taken.
Optical Power Budget
Electromagnetic Interference (EMI)
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 es-
tablish 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.
Most equipment designs using the AFCT-575xZ SFPs are
subject to the requirements of the FCC in the United
States, CENELEC EN55022 (CISPR 22) in Europe and VCCI
in Japan. The metal housing and shielded design of the
transceiver minimize EMI and provide excellent EMI
performance.
EMI Immunity
The AFCT-575xZ transceivers have a shielded design to
provide excellent immunity to radio frequency electro-
magnetic fields which may be present in some operating
environments.
Process Plug
This transceiver is supplied with a process plug for
protection of the optical port within the LC connector
receptacle. This process plug prevents contamination
during handling, shipping and storage. It is made of a
high-temperature, molded sealing material that can
withstand +85 °C.
Eye Safety
The AFCT-575xZ transceivers provide Class 1 eye safety
by design. Avago Technologies has tested the transceiver
design for regulatory compliance, under normal operat-
ing conditions and under a single fault condition. See
Table 1.
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 interna-
tional Cletop stick type (diam. 1.25 mm) and HFE7100
cleaning fluid.
Flammability
The AFCT-575xZ family of SFPs is compliant to UL 94V-
0.
Customer Manufacturing Processes
This module is pluggable and is not designed for aque-
ous wash, IR reflow, or wave soldering processes.

Notes:
1. TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on the host board. Pull up voltage between
2.0 V and VccT, R+0.3 V. When high, 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. By default, TX_FAULT is set to trigger on hardware faults only.
2. TX Disable input is used to shut down the laser output per the state table below with an external 4.7 - 10 KΩ 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-DEF 0,1,2. These are the module definition pins. They should be pulled up with a 4.7 - 10 KΩ 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 KΩ 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.
5. RD-/+: These are the differential receiver outputs. They are ac coupled 100Ω differential lines which should be terminated with 100Ω 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 500 and 2000 mV differential (250 - 1000 mV single ended) when properly terminated.
6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 - 3.465 V at the SFP connector pin. The maximum sup-
ply current is 250 mA and the associated inrush current will be no more than 30 mA above steady state after 500 nanoseconds.
7. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100Ω 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), though it is recommended that values between 500 and 1200 mV differential (250 - 600 mV single ended) be
used for best EMI performance.
