Corning Leaf fiber has a spec of 2.0 – 6.0 ps/(nm.km) for dispersion. Subtract 10% from the
15454’s OC-48 ELR dispersion tolerance for a margin of error. What is the maximum distance a
signal from an OC-48 100GHz ELR card can go before becoming dispersion limited?

The graph represents optical signal power versus wavelength measurement from 1550nm to
1560nm. The laser type that provides very narrow spectral widths, (<10ukHz) in the 1550nm range
for DWDM applications (as shown in graph), is an example of a:
