A. Hamel et al., INCREASED CAPACITY IN AN MS PROTECTION RING USING WDM TECHNIQUE AND OADM - THE COLORED SECTION RING, Electronics Letters, 32(3), 1996, pp. 234-235
The authors present a new method for upgrading the capacity of an exis
ting SDH ring without having to either install additional rings or use
higher bit rate equipment. The optimisation is obtained by assigning
a specific wavelength to each multiples section (MS) of the SDH ring.
With wavelength routing new possibilities are provided in the network
for addressing each node separately, with an order independent of the
physical location.
