Keysight-Agilent 83446B

Lightwave Clock Data Receiver

The Agilent 83446A/B lightwave clock/data receivers are designed to extract clock and data information from digitally modulated lightwave signals. They operate at the following SONET/SDH rates:
Agilent 83446A ... 2.48832 Gb/s
Agilent 83446B ...622.08 Mb/s

Both receivers have been designed per the recommendations of ITU-T G.957, G.958, and Bellcore GR-253-CORE for the 1310/1550 nanometer wavelength ranges. Outputs are optimized for use with bit-error-ratio testers, such as the Agilent 71604B.

Select optical or electrical input:
An input on the rear panel is provided for recovering clock and data from an electrical signal at the specifed data rate. A slide switch on the rear panel selects between the front panel optical input and the rear panel electrical input. For best sensitivity, signals should not be applied to both the front and rear panel inputs simultaneously.

Monitor the quality of the analog eye:
The auxiliary output on the front panel can be used to monitor the quality of the analog eye. When monitoring an optical signal this output is gain-limited by the AGC amplifer and its level is constant for input signals above approximately ..23 dBm. When monitoring an electrical signal this output is not gain-limited so its level is directly proportional to the incoming signal level.
