Sized just right—for increased port density
and reduced power consumption
Small Form Factor Transceiver Product Family
Highlights
Flexible, self-configuring 1 or
2 Gbps transmission rates for
current or future speeds
providing seamless transition
Robust, reliable VCSEL short-
wave and Fabry Perot long-wave
lasers for distance requirements
Transmission rates from 1.0625
to 2.125 Gbps supported by
Pin-Through-Hole (PTH) and
hot-pluggable versions
Manufactured to meet ANSI
Fibre Channel and IEEE Gigabit
Ethernet standards
Increase density, flexibility and
reduce power
IBM SFFs allow manufacturers to double
the density of transceivers on a board
compared to what was possible with
GBICs, thereby allowing increased
network connections. The small footprint
of the IBM SFF enables its use in
applications where dimension con-
straints are critical to overall design.
The compact design incorporates an
integrated photodetector and preamp on
a single chip and an integrated laser
driver and post amp on a single chip.
IBM SFF transceivers are bidirectional
devices. They can receive serial optical
signals and convert them into electrical
signals or receive electrical signals
and retransmit them as optical signals.
IBM SFFs are designed to maintain
signal integrity throughout the transmis-
sion process. Our SFFs have bit error
rates of less than 10
-12
.
Small-form-factor technology
IBM offers a variety of SFF designs and
data rates to meet speed and configura-
tion specifications. IBM SFFs are
available in PTH and pluggable versions
that are easy to integrate and connect.
Rates from 1.063 Gbps up to 2.125 Gbps
using short or long wavelength lasers
are available. Enhanced design features
include frequency agility, reduced power
consumption and lower cost transmission.
Leading the networked world
The IBM Small Form Factor (SFF)
product family is designed for a wide
range of networking applications
requiring high data rates, from gigabit
Ethernet and gigabit Fibre Channel to
client/server environments and distrib-
uted multiprocessing, as well as data
acquisition. As demand for networking
capabilities and rapid data transmission
become more critical, IBM products and
solutions can help you meet the changing
technological challenges you face.
