Bit rate
1. Fiber coupled power, connector repeatability is 1 dB.
2. Full spectral width measured 20 dB down from the central wavelength peak under fully modulated conditions (for DFB lasers).
3. Ratio of the average output power in the dominant longitudinal mode to the power in the most significant side mode under fully modulated conditions.
4. Ratio of logic 1 output power to logic 0 output power under fully modulated conditions. When operated at data rates below 1 Gb/s, the maximum extinction ratio
specification is increased by 2 dB.
5. Using an unfiltered measurement.
6. Formatted OC-48 pattern with scrambled PRBS 23 payload using Agilent Omni BER as the optical source driving an external OC-48 optical receiver with CDR. The
differential data outputs of this optical receiver with CDR. The differential dataoutputs of this optical receiver are used as the electrical inputs for the CT2 transmitter which
optically drives the Omni BER receiver input.
