Agilent HFBR-5710L/LP
Small Form Factor Pluggable
Optical Transceiver for Gigabit
Ethernet (1.25 GBd)
Data Sheet
Applications
• Switch to switch interface
• Switched backplane applications
• File server interface
• iSCSI applications
Description
The HFBR-5710L optical
transceiver is compliant with the
specifications set forth in both the
IEEE802.3 (1000BASE-SX), and
the Small Form-Factor Pluggable
(SFP) Multi-Source Agreement
(MSA). Its primary application is
servicing Gigabit Ethernet links
between optical networking
equipment. It offers previously
unavailable system cost, upgrade,
and reliability benefits by virtue of
being hot-pluggable. Further, it
incorporates the latest 3.3 VDC
compatible transceiver technology
including an 850 nm VCSEL
transmitter as well as a convenient
LC-Duplex optical interface.
Features
• IEEE 802.3 Gigabit Ethernet (1.25
GBd) 1000BASE-SX compliant
• Small Form Factor Pluggable (SFP)
Multi-Source Agreement (MSA)
compliant
• Manufactured in an ISO 9001
compliant facility
• Hot-pluggable
• Optional extended de-latch for
high density applications as shown
in Figure 10

– HFBR-5710L standard de-latch
• +3.3 V DC power supply
• Industry leading EMI performance
for high port density
• 850 nm Vertical Cavity Surface
Emitting Laser (VCSEL)
• Eye safety certified:
– US 21 CFR(J)
– EN 60825-1 (+All)
• LC-Duplex fiber connector
compatible
• Fiber compatibility:

Overview
The HFBR-5710L offers maxi-
mum flexibility to designers,
manufacturers, and operators of
Gigabit Ethernet networking
equipment. A pluggable architec-
ture allows the module to be
installed into MSA standard SFP
ports at any time – even with the
host equipment operating and
online. This facilitates the rapid
configuration of equipment to
precisely the user’s needs –
reducing inventory costs and
network downtime. Compared
with traditional transceivers, the
size of the Small Form Factor
package enables higher port
densities.
Module Diagrams
Figure 1 illustrates the major
functional components of the
HFBR-5710L. The external
configuration of the module is
depicted in Figure 7. Figure 8
depicts the panel and host board
footprints.
Installation
The HFBR-5710L can be installed
in or removed from any MSA-
compliant Pluggable Small Form
Factor 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
3-stage pin sequencing at the
electrical interface. This printed
circuit board card-edge connector
is depicted in Figure 2.
As the HFBR-5710L is inserted,
first contact is made by the
housing ground shield, dis-
charging any potentially
component-damaging static
electricity. Ground pins engage
next and are followed by Tx and
Rx power supplies. Finally, signal
lines are connected. Pin functions
and sequencing are listed in
Table 2.
