AFBR-703ASDZ
10Gb Ethernet, 850 nm, 10GBASE-SR,
Extended Temperature, SFP+ Transceiver
Data Sheet
Description
The Avago AFBR-703ASDZ transceiver is part of a family
of SFP+ products. This transceiver utilizes Avago’s 850nm
VCSEL and PIN Detector technology to provide an IEEE
10Gb Ethernet design compliant with the 10GBASE-SR
standard. The AFBR-703ASDZ transceiver is designed
with an extended case temperature to 0-85 °C to en-
able 10Gb Ethernet equipment designs with very high
port density based on the new electrical and mechani-
cal specification enhancements to the well known SFP
specifications developed by the SFF Committee. These
specifications are referred to as SFP+ to recognize these
enhancements to previous SFP specifications used for
lower speed products. Avago Technologies is an active
participant in the SFF Committee specification develop-
ment activities.

Regulatory Compliance
The AFBR-703ASDZ complies with all applicable laws
and regulations as detailed in Table 1. Certification level
is dependent on the overall configuration of the host
equipment. The transceiver performance is offered as a
figure of merit to assist the designer.
Electrostatic Discharge (ESD)
The AFBR-703ASDZ is compatible with ESD levels found
in typical manufacturing and operating environments
as described in Table 1. In the normal handling and op-
eration of optical transceivers, ESD is of concern in two
circumstances.
The first case is during handling of the transceiver prior
to insertion into an SFP compliant cage. To protect the
device, it’s important to use normal ESD handling pre-
cautions. These include use of grounded wrist straps,
work-benches and floor wherever a transceiver is han-
dled.
The second case to consider is static discharges to the
exterior of the host equipment chassis after installation.
If the optical interface is exposed to the exterior of host
equipment cabinet, the transceiver may be subject to
system level ESD requirements.
Electromagnetic Interference (EMI)
Equipment incorporating 10 gigabit transceivers is
typically subject to regulation by the FCC in the United
States, CENELEC EN55022 (CISPR 22) in Europe and VCCI
in Japan. The AFBR-703ASDZ enables equipment com-
pliance to these standards detailed in Table 1. The metal
housing and shielded design of the AFBR-703ASDZ
minimizes the EMI challenge facing the equipment de-
signer. For superior EMI performance it is recommended
that equipment designs utilize SFP+ cages per SFF 8432.
RF Immunity (Susceptibility)
Due to its proprietary bulk optics TOSA and ROSA de-
sign, the EMI immunity of the AFBR-703ASDZ exceeds
typical industry standards.
Eye Safety
The AFBR-703ASDZ provides Class 1 (single fault toler-
ant) eye safety by design and has been tested for com-
pliance with the requirements listed in Table 1. The eye
safety circuit continuously monitors the optical output
power level and will disable the transmitter upon de-
tecting a condition beyond the scope of Class 1 certi-
fication Such conditions can be due to inputs from the
host board (Vcc fluctuation, unbalanced code) or a fault
within the transceiver. US CDRH and EU TUV certificates
are listed in table 1.
Flammability
The AFBR-703ASDZ optical transceiver is made of metal
and high strength, heat resistant, chemical resistant and
UL 94V-0 flame retardant plastic.

Notes:
1. Rp is the pull up resistor. Active bus termination may be used by the host in place of a pullup resistor. Pull ups can be connected to various
power supplies, however the host board design shall ensure that no module contact has voltage exceeding VccT or VccR by 0.5 V nor requires
the module to sink more than 3.0 mA current.
2. Ci is the capacitance looking into the module SCL and SDA contacts
3. Cb is the total bus capacitance on the SCL or SDA bus.
