1. Iop, Tcase = 25C. Test with the laser Input pin matched to a 50 system.
2. IIP3 is measured at Ibb where Ibb is the bias point at which simultaneously the laser at its best linearity and the optical
power is within specification. Test Frequency F1 = 2700MHz, F2 = 2703MHz, RF in = 0dBm/frequency. 0km fiber.
3. Test at 2700MHz. 0km fiber.
4. Guaranteed by design. Not to be tested in production
