Note (2). When LOS asserted, the data output is Low-level (fixed)
Note (3). When the terminal is viewed from the optical path, the reflection toward the optical path of the
optical signal with a central wavelength of 1260nm to 1360nm transmitted to terminal.
Note (4). These are 20%~80% values
Note (5). X=10 MHz, Rectangular BER =10
