Optical networks as defined by the IEEE 802.3ah standard suffer from
Stimulated Raman Scattering (SRS) that causes data transmission at a
first optical wavelength to interfere with broadcast video transmission
at a second optical wavelength in single mode optical fibers. The problem
is exacerbated when data is not being transmitted across the network; and
instead, an idle pattern transmission is being transmitted in order to
keep the network synchronized. The repetitive nature of the idle pattern
transmission leads to the SRS optical interference effect. This optical
interference effect is mitigated when countermeasures are implemented to
modify the idle pattern transmissions or to transmit random data in place
of the idle pattern transmissions.
