This Recommendation defines interface parameters for systems of four, eight and sixteen channels operating at bit rates of up to STM-16 on fibres, as described in Recommendations G. 655 with nominal span lengths of 80 km, 120 km and 160 km and target distances between. This Recommendation specifies multichannel optical line system interfaces for the purpose of providing future transverse compatibility among such systems. An historical perspective of the various ITU recommendations is provided in this chapter, addressing not only the maturation of the industry but also the intent to use standards to modify the application space from low-volume and high cost conditions to. Let N1+N2=Ntotal, and ad be the cross-sectional area of the doped portion of the fiber core. The steady state solution for the rate equations reduces to N 2(z) = ! For a given pump power, the.
