HARACTERISTICS
The XPD0250CT-001 can handle input optical power from 6碌W to 1.7mW which is equivalent to a
dynamic range of 49dB. At low input optical power, the transimpedance gain ZT must be high to
obtain enough output voltage, and the noise should be low enough to guarantee a minimum bit error
rate. The transimpedance is regulated from 4
銖€
at low input optical power (Po<30碌W) to 80鈩t
high power (Po =1.7mW).
