The graph represents optical signal power versus wavelength measurement from 1550nm to 1560nm. The laser type that provides very narrow spectral widths, (<100kHz) in the 1550nm range for DWDM applications (as shown in the graph), is an example of a:
A.
Red Light Emitting Diode laser
B.
Fabry-Perot laser
C.
Distributed Feedback laser
D.
Edge Emitting LED laser
E.
Vertical Cavity Surface Laser
