Serial Identication (EEPROM)
The HFBR-57E0 complies with the industry standard
MSA that denes the serial identication protocol. This
protocol uses the 2-wire serial CMOS E2PROM protocol
of the ATMEL AT24C01A or equivalent. The contents of
the HFBR-57E0 serial ID memory are dened in Table 3 as
specied in the SFP MSA.
Functional Data I/O
The HFBR-57E0 beroptic transceiver is designed to ac-
cept industry standard dierential signals. In order to re-
duce the number of passive components required on the
customer’s board, Avago has included the functionality
of the transmitter bias resistors and coupling capacitors
within the beroptic module. The transceiver is compat-
ible with an “ac-coupled” conguration and is internally
terminated. Figure 5 depicts the functional diagram of
the HFBR-57E0.
Regulatory Compliance
See Table 1 for transceiver Regulatory Compliance perfor-
mance. The overall equipment design will determine the
certication level. The transceiver performance is oered
as a gure of merit to assist the designer.

Electrostatic Discharge (ESD)
There are two conditions in which immunity to ESD
damage is important. Table 1 documents our immunity
to both of these conditions. The rst 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.
These precautions include using grounded wrist straps,
workbenches, and oor mats in ESD controlled areas.
The ESD sensitivity of the HFBR-57E0 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
HFBR-57E0 exceeds typical industry standards.
Immunity
Equipment hosting the HFBR-57E0 modules will be sub-
jected to radio-frequency electro magnetic elds in some
environments. These transceivers have good immunity to
such elds due to their shielded design.
