(a) Measured with specified bias voltage of 12 V.

(b) For a 50 Ω Load

(c) Although these detectors have FC/PC input connectors, our testing shows that they may be used with FC/APC patch cables with no measurable differences in performance.

(d) A higher output voltage will decrease the bandwidth.

(e) Calculated based upon peak responsivity and damage threshold.

(f) Low battery voltage will result in slower rise times and decreased bandwidth.

(g) These rise and fall times are tested and guaranteed in our production units. A theoretical rise time of 292 ps can be calculated using the formulas found in chapter 4.6 of the manual or the Photodiode Tutorial tab.

(h) For a 1 MΩ Load
