The Agilent 83433A transmitter and the Agilent 83434A receiver provide the optical interfaces necessary to allow bit error ratio testing of 10 Gb/s optical transmitters and receivers used in 10 Gb/s SONET/SDH, 10 GigE, and IP optical net-works as well as systems employing forward error correction (FEC).
The 83433A and 83434A may be combined to create a complete optical link for system or fiber testing. The 83434A receiver’s non-retimed output is designed for use with the Agilent 71612C 12.5 Gb/s Error Performance Analyzer. The 71612C can optimize the receiver output decision threshold and timing to optimize BER. Because of this, Q-factor and eye contour analysis for optical signal degradation testing can be accomplished using the 83434A, 71612C and the E4543A Q-factor and eye-contour analysis software.
The 83434A receiver can also be used for optical eye diagram analysis with a sampling oscilloscope, such as the 86100B Infiniium DCA, when no separate clock signal is available or when an optical channel is not available. The clock output of the 83434A can be used to trigger an oscilloscope at 9.953 Gb/s (or 10.664 Gb/s with option 83434A-106, or 10.3125 Gb/s with option 83434A-H31) ensuring that the eye diagram is an accurate representation of all possible bit combinations on the incoming data stream. The non-retimed linear data output allows for diagnostic analysis of the incoming waveform.
