Module Package
The transceiver meets the Small
Form Pluggable (SFP) industry
standard package utilizing an
integral LC-Duplex optical
interface connector. The hot-
pluggable capability of the SFP
package allows the module to be
installed at any time – even with
the host system operating and on-
line. This allows for system
configuration changes or
maintenance without system
down time. The HFBR-5720AL/
ALP uses a reliable 850 nm
VCSEL source and requires a 3.3
V DC power supply for optimal
design.
Module Diagrams
Figure 1 illustrates the major
functional components of the
HFBR-5720AL/ALP. The
connection diagram of the
module is shown in Figure 2.
Figure 7 depicts the external
configuration and dimensions of
the module.

Installation
The HFBR-5720AL/ALP 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 3-stage 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)

Signal pins, making contact with
the host board surface mount
connector in that order. This
printed circuit board card-edge
connector is depicted in Figure 2.
Serial Identification (EEPROM)
The HFBR-5720AL/ALP complies
with an industry standard MSA
that defines the serial
identification protocol. This
protocol uses the 2-wire serial
CMOS E2PROM protocol of the
ATMEL AT24C01A or equivalent.
The contents of the HFBR-
5720AL/ALP serial ID memory
are defined in Table 10 as
specified in the SFP MSA.
