areas. The ESD sensitivity of the AFBR-571xZ is compat-
ible with typical industry production environments.
The AFBR-571xZ transciever is capable of transmission
at 2 to 550 meters with 50/125 µm fiber, and at 2 to 275
meters with 62.5 125 µm fiber, for 1.25 GBd Ethernet. It
is capable of transmission up to 500m with 50/125 µm
fiber and up to 300m with 62.5/125 µm fiber, for 1.0625
GBd Fiber Channel.
The second case to consider is static discharges to the
exterior of the host equipment chassis after installation.
To the extent that the optical interface is exposed to the
outside of the host equipment chassis, it may be subject
to system-level ESD requirements.
Application Support
Electromagnetic Interference (EMI)
To assist in the transceiver evaluation process, Agilent
offers a 1.25 Gbd Gigabit Ethernet evaluation board
which facilitates testing of the AFBR-571xZ. It can be
obtained through the Agilent Field Organization by ref-
erencing Agilent part number HFBR-0571.
Equipment using the AFBR-571xZ family of transceivers
is typically required to meet the requirements of the
FCC in the United States, CENELEC EN55022 (CISPR 22)
in Europe, and VCCI in Japan.
A Reference Design including the AFBR-571xZ and the
HDMP-1687 GigaBit Quad SerDes is available. It may be
obtained through the Agilent Field Sales organization.
The metal housing and shielded design of the AFBR-
571xZ minimize the EMI challenge facing the host equip-
ment designer.
Regulatory Compliance
EMI Immunity
See Table 1 for transceiver Regulatory Compliance. Certi-
fication 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.
Equipment hosting AFBR-571xZ modules will be sub-
jected to radio-frequency electromagnetic fields in some
environments. The transceiver has excellent immunity to
such fields due to its shielded design.
Electrostatic Discharge (ESD)
Flammability
The AFBR-571xZ exceeds typical industry standards and is
compatible with ESD levels found in typical manufactur-
ing and operating environments as described in Table 1.
The AFBR-571xZ transceiver is made of metal and high
strength, heat resistant, chemically resistant, and UL
94V-0 flame retardant plastic.
There are two design cases in which immunity to ESD
damage is important.
Customer Manufacturing Processes
This module is pluggable and is not designed for aqueous
wash, IR reflow, or wave soldering processes.
The first case is during handling of the transceiver prior
to insertion into the transceiver port. To protect the trans-
ceiver, it’s important to use normal ESD handling precau-
tions. These precautions include using grounded wrist
straps, work benches, and floor mats in ESD controlled
