Overview
The HFBR-5701L offers maximum flexibility to designers,
manufacturers, and operators of Gigabit Ethernet net-
working equipment. A pluggable architecture 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 transceiv-
ers, the size of the Small Form Factor package enables
higher port densities.

Installation
The HFBR-5701L can be installed in or removed from any
MSA-compliant Pluggable Small Form Factor port regard-
less 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-5701L is inserted, first contact is made by
the housing ground shield, discharging 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 se-
quencing are listed in Table 2.
Before extracting the module, the black plastic tab beneath
the optical port must be depressed, releasing the latch
mechanism. The transceiver can then be pulled out of the
port manually by gripping the side of the LC ports.
For easier fingertip delatching in high port density ap-
plications, an optional extended tab is offered as shown
in Figure 10.
Serial Identification (EEPROM)
The HFBR-5701L features an EEPROM for Serial ID. It
contains the product data stored for retrieval by host
equipment. This data is accessed via the 2-wire serial
EEPROM protocol of the ATMEL AT24C01A or similar in
compliance with the industry standard SFP Multi-Source
Agreement. Contents of the HFBR-5701L serial ID memory
are displayed in Table 9.
