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.
