Countermeasures for idle pattern SRS interference in ethernet optical network systems

摘要: 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 second in single mode fibers. The problem is exacerbated when not being transmitted across network; and instead, an idle pattern order keep network synchronized. repetitive nature of leads SRS interference effect. This effect mitigated countermeasures are implemented modify transmissions or transmit random place transmissions.
