OPTICAL WAVEFORMS

VCC = 3.3 V and TA = 25°C, unless otherwise noted. Note that there was no change to PAVCAP and ERCAP values when different data

rates were tested. Figure 23, Figure 24, and Figure 25 show multirate performance using the low cost Fabry Perot TOSA NEC NX7315UA;

Figure 26 and Figure 27 show performance over temperature using the DFB TOSA Sumitomo SLT2486.
