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.

DSC710 and DSC720 Balanced InGaAs Photodiodes to 20 GHz       DSC710 and DSC720 Lab Buddy. For busy test stations or student labs, where users of different experience levels might be handling high value opto-electronics that are easily damaged by mishandling, order your photodiode to be mounted in the Lab Buddy
