Note (2). Specified with minimum optical extinction ration of 9dB.
Note (3). When LOS asserted, the data output is Low-level (fixed)
Note (4). 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.
