Capacity Benefits of Operation Over C+L Band Elastic Optical Network in the Indian Network Scenario
2020
Introduction of high data rate services has increased
the traffic load on the backhaul network. In order to cater
more demands, the operators are looking for solutions to minimize spectral wastage and to extend their network operations
beyond the C-band, especially for inter-city networks. This
paper highlights the advantages of operating over C+L band as
compared to operations over C band in a large Indian network.
The physical model factors in the non-linear interference (NLI)
due to inter-channel stimulated Raman scattering (ISRS) and
amplified spontaneous emission (ASE) noise while estimating the
optical signal to noise ratio (OSNR) of a network lightpath. The
OSNR estimation model can dynamically account for the NLI
as compared to the conventional worst case assumption. The
capacity benefits for the Indian network over the C+L band
for channel power -1.5 dBm are about 108.67% for channel
bandwidth 50 GHz and 103.98% for channel bandwidth 37.5
GHz until 10% of the demands are blocked.
