Digital 2-R Optical Receivers


Description:

These modules add the extra sensitivity of an APD to the 2-R functions receive and regenerate mounted in a pigtailed 8-pin butterfly package, the modules save system designers board space while improving performance and reliability. Our DSC-R601APD model provides a type K coaxial RF output and has a single-ended limiting amplifier providing a constant ~300 mVpp to following stages with optical input powers from -22 to -6 dBm. Our DSC-R602APD model provides dual sub-miniature coaxial outputs and has a differential limiting amplifier providing a constant ~600 mVpp to the following stages. The InGaAs Infrared APD is ideal for 1330 and 1550 nm systems.

Salient Features

  • High Sensitivity: -22 dBm @ 10-12, PRBS 231 -1
  • Same small footprint and pinout for PIN and APD versions of the 2-R receivers
  • 8-pin butterfly package with type K coaxial RF output for R601APD model and push-on GPPO/SSMP compatible RF outputs for R602APD model
  • Differential output for common mode rejection (only available in model R602APD)
  • User selectable decision point (Vadj)
  • Hermetically sealed

Applications:

  • 10 Gigabits per second digital receiver for telecom and datacom
  • Short, intermediate and long haul systems
  • DWDM systems
  • SONET/SDH systems
  • Datacom systems
  • Test & measurement analyzers

Available Models:

  • DSC-R601APD - Single-ended Digital 2-R APD Optical Receivers
  • DSC-R602APD - Differential Digital 2-R APD Optical Receivers
