Optical Isolation		25			dB	Note (6)

Note (1). Measured with 1520nm, ER=10dB; BER =<10-10@PRBS=223-1 NRZ Note (2). When SD 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 1580nm transmitted to terminal.

Note (4). These are 20%~80% values

Note (5). X=10 MHz, Rectangular BER =10-10

Note (6). Receiver isolation between 1260nm ~1360nm
