Notes
1. Measured at 2488.32Mbps, PRBS 223-1, 50% duty cycle, NRZ.
2. Maximum dispersion values correspond to the approximate w orst-case dispersion (to 1600ps/nm) at 1610nm.
3. For the jitter measurements, the device w as driven w ith SONET OC-48 data pattern w ith 223-1 PRBS payload.
Measured w ith a bandpass filter having a high-pass cutoff frequency of 12k Hz and a low -pass frequency of 20MHz.
Compliant w ith Telecordia GR-253 CORE and ITU-T G957
