Note (1). Measured with 1490nm, ER=10dB; BER =<10-10@PRBS=223-1 NRZ without FEC 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
