Agilent 83437A
Broadband Light Source
Technical Specifications
January 2004
Incoherent light sources for single-mode-fiber
component and subsystem characterization.
The Technology
The Agilent Technologies 83437A
Broadband Light Source (BBLS) is
based on Agilent Technologies’ edgeemitting LED (EELED) technology. An
EELED provides significantly more
power density into a single-mode fiber
than a regular LED and more than one
hundred times that of a white light
source.
Built-to-order, the 83437A can
incorporate up to four EELEDs, with
five available wavelengths in the 1200
to 1650 nm range. Connectors on the
back panel allow you to modulate the
light by applying a TTL compatible
signal, or to selectively turn any of the
EELEDs on (open connection) or off
(shorted).
In configurations with multiple
EELEDs installed, optical couplers
combine the light to a single output. In
order to minimize coupler losses,
Agilent uses wavelength-dependent
and wavelength-independent couplers
depending on the ordered
configuration.
Agilent 83437A block diagram (shown with 83437A - 003, 004, 006, and 705). Only the
1310/1550 and the 1430/1650 couplers are wavelength dependent to minimize loss. All
others are standard '3 dB' couplers.
Furthermore, an optional isolator and
angled contact output connector help
to increase the instrument’s return
loss for applications sensitive to
reflections in the test setup.

Your Benefits
Respond to market pressure…
Manufacturers of fiberoptic
components and subsystems are
experiencing a dynamic and
competitive market. This increases the
pressure on profit margins so
production costs must decrease while
the devices become more complex.
Per-unit test cost, as well as the initial
investment in test instrumentation
needs to be reduced.
...to improve the quality and the
performance of your device...
Together with an optical spectrum
analyzer (OSA), the
Agilent Technologies 83437A will
ensure that your device is accurately
characterized. Reliable and repeatable
measurements help to tighten
margins, allowing you to sell a better
product with greater profit due to a
higher yield.
...while increasing throughput.
The significantly higher power density
compared to white-light and regular
LED sources allows much faster OSA
sweep times. Whether you need only a
simple test versus wavelength or a
complex characterization including
polarization and other effects, test
setups using these sources
significantly reduce your total
measurement time.
Basic stimulus/response setup
..with just the right
equipment...
The JET philosophy (Just Enough
Test) provides the right amount of
capability necessary for key
component and subsystem tests (see
next pages) without excessive
features or a complicated user
interface.
