Rise and fall times tr, tf Note 2 60 100 ps Total jitter Tj Note 3 35 70 ps 2. Defined as the difference between the maximum and minimum threshold currents measured for a given array. 3. Using 1111100000 pattern at 2.5 Gb/s, drive the VCSEL through a bias-tee with an ac signal adjusted for an extinction ratio (ER) of greater than 10 dB, with average optical output power (Pave) of 1.0 mW, measured at 25C. 4. Sum of the deterministic and random jitter components @ 2.5Gbps, measured at 25C. Deterministic jitter is measured using 0011111010 1100000101 pattern at 50% crossing. Random jitter, which is defined as 14 times the standard deviation, is measured using 1111100000 pattern. The VCSEL is driven through a bias-tee with an ac signal adjusted for an ER of greater than 10 dB, with Pave of 1.0 mW.
