This assurance should be met with asynchronous data flowing out of the optical transmitter of
the system under test. The output data pattern from the transmitter of the system under test is a
repetition of alternate 0/1 pattern as defined for this measurement.

Note (2). When SD deasserted, the data output is Low-level (fixed)
Note (3). These are 20%~80% values.
Note (4). Measured at wavelength of 1490nm.
