AFBR-732BE

Manufacturer Part Number
AFBR-732BE
Description
Ultra Short Link Pluggable Parallel Fiber Optic Modules, Transmitter and Receiver
Manufacturer
HP [Agilent(Hewlett-Packard)]
Datasheet
Description
The AFBR-732B transmitter
and AFBR-742B receiver are
high performance fiber optic
modules for parallel optical
data communication
applications. These 12-channel
devices, operating up to 2.5Gbd
per channel, provide a cost
effective solution for short-
reach applications requiring up
to 30 Gb/s aggregate bandwidth.
These modules are designed to
operate on multimode fiber
systems at a nominal
wavelength of 850 nm. They
incorporate high performance,
highly reliable, short
wavelength optical devices
coupled with proven circuit
technology to provide long life
and consistent service.
The AFBR-732B transmitter
module incorporates a 12-
channel VCSEL (Vertical Cavity
Surface Emitting Laser) array
together with a custom 12-
channel laser driver integrated
circuit providing IEC-60825
and CDRH Class 1M laser eye
safety.

Agilent AFBR-732B/BE and AFBR-
742B/BE Ultra Short Link Pluggable
Parallel Fiber Optic Modules,
Transmitter and Receiver
Data Sheet
The AFBR-742B receiver
module contains a 12-channel
PIN photodiode array coupled
with a custom preamplifier /
post amplifier integrated
circuit.
Operating from a single +3.3 V
power supply, both modules
provide LVTTL or LVCMOS
control interfaces and Current
Mode Logic (CML) compatible
data interfaces to simplify
external circuitry.
The transmitter and receiver
devices are housed in MTP®/
MPO receptacled packages.
Electrical connections to the
devices are achieved by means
of a pluggable 10 x 10
connector array.
Ordering Information
