4. Measured at PRBS 2

5. Represents sensitivity based on OMA spec, as corrected to incoming Extinction Ratio of 9 dB. For example, an OMA of 29

µW is

approximately equal to an average power of -17.3 dBm, average with an Extinction ratio of 9 dB.

6. Open collector compatible, 4.7K to 10K ohm pull-up to Vcc (Host Supply Voltage).
