1. Measured as fiber coupled power into a standard single mode fiber, typical connector repeatability is ±1 dB. LC duplex cables manufactured by Stratos are not

recommended due to a potentially larger window of repeatability.

2. Full spectral width measured 20 dB down from the central wavelength peak under fully modulated conditions.

3. Ratio of the average output power in the dominant longitudinal mode to the power in the most significant side mode in fully modulated conditions.

4. Ratio of logic 1 output power to logic 0 output power under fully modulated conditions with a PRBS 23 data pattern.

5. GR-253-CORE, ITU-T, Recommendation G.957. Tested at STM1, STM4, STM16.

6. Formatted OC-12 pattern with scrambled PRBS payload using an Agilent OmniBer as the optical source driving the CT2 optical receiver. The differential data outputs of

this optical receiver are used as the electrical inputs for the CT2 transmitter which optically drives the OmniBer receiver input to complete the jitter test circuit. This is a 60

second test as recommended in GR-253.
