I want to detect light power in wavelength 1310 <--> 1550nm.
The specifications detect range is minimum -45dbm.
Since I have used 95:5 splitter, the minimum detect range has change to -59 dBm (-45-13dbm).
Unfortunately, my photodiode maximum sensitivity is -36dmn.
Can I change another photodiode (can detect minimum -60dbm)?
Do you have any suggestion for this problem?
Thank you.
