10 Gb/s Optical Interfaces
for Bit Error Ratio Testing
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 recovers clock and data from
digitally modulated SONET/SDH OC-192/STM-64 optical
signals. Option 83434A-106 substitutes clock recovery
for FEC signals at 10.664 GHz, and option 83434A-H31
recovers the clock for 10 GigE. The amplified PIN-diode
produces a linear output with AGC stabilization. The
receiver is designed to provide –16 dBm sensitivity for a
2
31
-1 PRBS with a BER performance of at least 1 x 10
-10
.
