Specification (Receiver)
Description
The 51.84/155.52/622.08 MHz output of the optical transmitter is checked for
power level at 1310 nm (and 1550 nm wavelengths if Option131). The receiver
sensitivity is verified by attenuating the transmitter output and checking for no
Wavelength 130 - 1280 nm to 1330 nm,
131 - 1280 nm to 1330 nm or 1520 nm to 1565 nm
Power Output 1310 nm -10 dBm (Nominal).
1550 nm -1dBm (Nominal)
