High speed optical fiber photodiode detector

1 Detector material:InGaAs

2 Wavelength response range:800nm1750nm

3 Peak response wavelength:1300nm

4 Saturated optical power: 6dBm (room temperature25Degree hour)

5 cut-off frequency:>2GHz

6 Rising edge: <200ps

7 Falling edge: <200ps

8 The output impedance inside the detector is1MOhm,If users need to obtain appropriate response speed,A suitable resistor must be connected in parallel at the output.To maximize the response frequency of the detector,Its output must be connected in parallel50Ohm-100Ohmic resistance(Generally, it can be connected in parallel50Ohmic terminal,Bandwidth is greater than or equal to300MHzThe oscilloscope itself also has50Ohmic impedance selection).The smaller the resistance of the output in parallel,The higher the peak power of the incident optical signal is required,Otherwise, its output voltage will be lower,Users need to find a balance between bandwidth and voltage.generally speaking,The detection pulse width is hundreds of nanoseconds,Picosecond or femtosecond laser pulse,The output of the detector needs to be connected in parallel50Ohm-100Ohmic resistance;If detector500usreach500nsLaser pulse,The detector output needs to be connected in parallel1k-10kOhmic resistance;If hundreds are detectedms-500usLaser pulse,The detector output needs to be connected in parallel10k-100kOhmic resistance;If the detection is greater than500msOr continuous laser,The detector output does not need parallel resistance,However, if the output voltage is high,Or to eliminate the influenc
