Balanced Photodiodes to 20 GHz Bandwidth

Description:

The DSC710 and DSC720 are "push-pull" InGaAs photodiodes with each photodiode capable of handling high optical power up to +14 dBm. High Common Mode Rejection Ratio (CMRR) and low Polarization Dependent Loss (PDL) make these devices ideal for both digital and analog applications. The broad wavelength response of these photodiodes allows for multiple wavelength usage.

Salient Features:

Lowest PDL (typical 0.05 dB)
Normalized CMRR exceeds 30 dB
Useable spectral wavelength range of 800-1650 nm
Improves sensitivity by canceling DC portion of RIN and ASE noise
High optical power handling InGaAs PIN photodiodes
Small form-factor fiber-pigtailed package
Improved reliability for high optical power handling
One device for multiple wavelengths reduces operational and inventory cost
OIP3 exceeding + 40dBm for highly linear option

Applications:

DPSK/DQPSK: Differential Phase/Polarization Shift Keying or Differential Quadrature Phase Shift Keying
High Dynamic Range, Analog RF Links over Fiber
Rapid Doppler-shift LIDAR measurements
Coherent Lightwave Systems
Brillouin Scattering - OTDR
Test and Measurement

Available Models:

DSC710 - Balanced Photodiodes to 10 GHz Bandwidth
DSC720 - Balanced Photodiodes to 20 GHz Bandwidth
