Note 3
Notes:
1. Measured at the end of 0.5 m standard fiber optic cable with large area detector.
2. Optical power, P (dBm) = 10 Log [P(µW)/1000
µW].
3. Rise and fall times are measured with a voltage pulse driving the transmitter and a series connected 50
Ω
load. A wide bandwidth
optical to electrical waveform analyzer, terminated to a 50
Ω
input of a wide bandwidth oscilloscope, is used for this response time
measurement.
