Note (1). Measured with 1490nm, ER=10dB; BER =<10
Note (2). When Signal Detect Deasserted, 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 1480nm to 1500nm transmitted to terminal.
Note (4). These are 20%~80% values
