Notes:

[1] Applied modulation is 9.953Gb/s, 2

[2] Linewidth is measured using 0.06nm resolution bandwidth.

[3] Optical eye parameters measured with a Communications Analyser with Agilent plug-in module 86106B option

410 (or equivalent plug-in with an 8GHz 4th Order Bessel-Thomson Filter). Optical 0/1 crossing typically 50%.

[4] Fiber characteristics are derived from the following equation;

Where So = 0.092 ps/(nm2.km) and l0 = 1302nm. Receiver sensitivity measured at a BER of 10

RX OSNR > 35dB, optimised RX CDR phase adjust and 50% CDR slice level.
