Transmitter Optical Characteristics
The following characteristics are defined over the Recommended Operating Conditions unless otherwise noted. Typical
values are for Tc = 40°C, Vcc33 = 3.3 V and Vcc25 = 2.5 V.
Notes:
1. The transmitter launch condition meets the requirements of 10 Gigabit Ethernet multimode fiber as detailed in TIA 492AAC.
2. These are unfiltered rise and fall times measured between the 20% and 80% levels using a 500 MHz square wave test pattern. Impairments in
3. Inter-Channel Skew is defined for the condition of equal amplitude, zero ps skew input signals.
4. Deterministic Jitter, DJ, conforms to the dual-Dirac model where TJ(BER) = DJ + 2Q(BER)RJrms and RJrms is the width of the Gaussian component.
5. Total Jitter, TJ, defined for BER of 10
6. Eye Opening is defined as the unit interval less TJ for the same test pattern and conditions as TJ. Measurement is made at the output, TP4, of the
