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 25°C.
4. Sum of the deterministic and random jitter components @ 2.5Gbps, measured at 25°C. 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.
