The 83433A lightwave transmitter is based on a lithium niobate modulator 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 8164A, with 81680A option 071.
The 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 transmission rates up through 10.7 Gb/s. The 83433A is intended for BER testing with error performance analyzers such as the 71612B. The Mach-Zehnder modulator is adjusted for a fixed zero chirp. Its output waveform producesa 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 83433A can be combined with the 83434A 10 Gb/s lightwave 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.
83434A 10Gb/s Lightwave Receiver
The 83434A 10 Gb/s lightwave receiver is designed to recover clock data and to provide linear, non-retimed data from digitally modulated SDH/ SONET STM-64/OC-192 optical signals, as well as signals employing forward error correction (FEC) at 10.664 Gb/s (option 106). The receiver is based on an amplified PIN receiver to produce a linear output with AGC stabilization. The receiver is designed to provide –16 dBm sensitivity with PRBS lengths to 231 –1 with BER performance of at least 1E-10.
The recovered clock can be used as a trigger input for the Infiniium DCA to allow optical eye diagram measurements when no external clock signal is available for triggering. The recovered clock also provides the required clock input for the error detector of the 71612B error performance analyzer. The non-retimed data output can be used with an error detector to measure and optimize BER. The output of the receiver is also appropriate for eye contour and Q-factor measurements.
The 83434A can be combined with the 83433A 10 Gb/s lightwave transmitter to create a complete optical link for system or fiber testing, or to form a basis for substitution testing of commercial transmitters and receivers.
The 83433A Keysight 10Gb/s Lightwave Transmitter may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
