When a high-power optical signal passes through a fiber, the photons can cause a “ringingof the crystal lattices within the glass fiber core. This ringing creates acoustic phonons,
which in turn interact with other photons of light. The result is an increase in noise in the
received RF signal. What is this phenomenon called?
A.
Chirp
B.
double Rayleigh backscattering
C.
stimulated Brillouin scattering (SBS)
D.
Raman pumping
