The Agilent 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 Agilent 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 Agilent 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 Agilent 83434A can be combined with the Agilent 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.
