Agilent / HP / Keysight 83446A

The Lightwave clock/data receiver is designed to extract clock and data information from digitally modulated lightwave signals at the SONET/SDH data rate of 2.48832Gb/sec (OC48/STM16).

It incorporates a high gain avalanche photodiode (APD), gain controlled amplifier, and clock/data recovery hybrid to deliver clean, error free outputs from optical signals with powers as low as -27dBm at either 1310 or 1550nm wavelength.

The Agilent 83446A has been designed especially for use with high speed bit error ratio testers (BERTs) such as the Agilent 86130A or 71612C.

By connecting the clock and data outputs to the corresponding inputs on the BERT'S error detector, bit error ratio analysis can be performed directly on optical signals, making it easy to do system acceptance and BER floor analysis.
