Note 1: Measured with 1310nm, 1.244Gbps PRBS223-1 burst-mode optical input, ER=10dB, BER=1x10-10; Single burst packet length is 40us and packet interval is 40us.
Note 2: Input optical power level difference of adjacent burst packets.
Note 3: Receiver optical power ranged from -8dBm to -28dBm, measured with 1310nm, 1.244Gbps PRBS27-1 burst-mode optical input, ER=10dB, 50%duty cycle.
Note 4: BPD assert low when module receive “Reset” signal, assert high when burst package is detected and latch to high state until next “Reset” signal.
