Agilent 83446A Lightwave Clock/Data Receiver 2.48832 Gb/sec

• Retrieve clock and data from optical signals
• Sensitive to <-27 dBm
• 2488 Mb/s rate

The Keysight 83446A lightwave clock/data receiver is designed to extract clock and data information from digitally modulated lightwave signals at the SONET/SDH data rate of 2.48832 Gb/sec (OC-48/STM-16). 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 -27 dBm at either 1310 or 1550 nm wavelength.

The Keysight 83446A has been designed especially for use with high-speed bit-error-ratio testers (BERTs) such as the Keysight 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. The Keysight 83446A also has an auxiliary port which allows monitoring of the output of the APD prior to regeneration.
