5. Measured at 2²³-1 PRBS at BER 1E-10. Receiver sensitivity is better than -45dBm at 155 Mbps and 125 Mbps. However, due to the
resolution limitation of Digital Diagnostic Monitoring, the effect readout range for the RX received power at EEPROM A2 is from -10
to -34 dBm.
6. At least 30 dB optical isolation for the wavelength 1580 to 1620 nm.
7. Open collector compatible, 4.7K to 10K ohm pull-up to Vcc (Host Supply Voltage).
