(a) The laser power modulator can be used outside the wavelength range. However, the damage threshold for wavelengths outside this range is unspecified and may be lower, especially for shorter wavelengths. The modulator may not be able to achieve full extinction for wavelengths higher than the max operating wavelength.

(b) The time required for the transmission to rise from 10% to 90%. Response depends on DC attenuation level.

(c) A 10 kΩ internal pull-down resistor holds the input voltage at 0 V if no input is provided.

(d) The recommended collimated input beam diameter (1/e2) is 1 to 2 mm.

(e) Independent of modulation level.
