The Agilent 83433A—At a Glance
The Agilent 83433A lightwave transmitter is based on a lithium niobate modu-
lator driven by an internal CW DFB 1552.52 nm laser. The laser and modulator
are inter-connected externally with a PMF fiber. The modulator can also be
used with an external laser with polarization maintaining fiber such as the Agi-
lent 8164A, with 81680A option 071.
The Agilent 83433A is designed to produce high fidelity, low jitter waveforms
for 2.488 Gb/s STM-16/OC-48, 9.953 Gb/s STM-64/OC-192 and other transmis-
sion rates up through 10.7 Gb/s. The Agilent 83433A is intended for BER test-
ing with error performance analyzers such as the Agilent 71612B. The Mach-
Zehnder modulator is adjusted for a fixed zero chirp. Its output waveform pro-
duces a minimum extinction ratio of 12 dB.
The internal DFB laser can be modulated at frequencies from 15 kHz to
10 MHz to increase linewidth for SBS suppression or channel identification
applications. The internal laser wavelength can be adjusted ±1.25 nm around
the 1552.52 center wavelength.
The Agilent 83433A can be combined with the Agilent 83434A 10 Gb/s light-
wave receiver to create a complete optical link for system or fiber testing, or to
form a basis for substitution testing of commercial transmitters and receivers.
