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.
