Receiver Module for Ultra Low Signal Detection

In the CIPRM-1 series balanced optical receiver, Excelitas has incorporated the best features of high performance InGaAs photodiodes and a low noise, high gain transimpedance amplifier to offer a practical solution to detect small changes above the interfering noise floor of an incoming signal. The advantage is that the common optical noise is cancelled out.

This coherent InGaAs PIN balanced receiver module incorporates two low-noise photodiodes with well-matched responsivity in order to ensure a high common mode rejection ratio (CMRR). It has two single mode fibre optic inputs, an RF output, electrical supply inputs, and two photo-current monitor outputs. The CIPRM modules come in a robust casing with flange mounting holes for securing the module to working surfaces or platforms. Combined with a wide operating temperature range, the CIPRM can work in some of the toughest and harshest environments.
Key Features include:

  • Spectral range - 800 - 1650nm
  • 200MHz bandwidth
  • High performance InGaAs photodiode and TIA
  • Matching responsivity
  • Photo-current monitor outputs
  • Rugged and robust
  • RoHS compliant

Applications:

  • Spectroscopy
  • Optical delay measurement
  • Heterodyne detection
  • Optical coherent tomography
  • Ellipsometry
  • Ultra low signal detection
