The authors report the first comparison, at the national standards level, of photodiode frequency response measurements at wavelengths of 1.285, 1.319 and 1.531 µm. A photodiode was measured up to 40 GHz and the results were normalised to 1.319 µm using a model of the device. The average scatter in the results was ±0.12 dB (2σ) below 20 GHz and ±0.21 dB from 20 to 33 GHz.
