Internet trafﬁc is continuously increasing. To accommodate this increased trafﬁc, the optical transmission rates are moving from 40 Gbit/s to 100 Gbit/s. However they can also coexist in the same ﬁber. The crucial premise for network providers choose the transmission bit rate is cost efﬁciency. The Capital Expenditures (CapEx) are of paramount importance at the network design stage. However, due to the increasingly stringent economies of telecommunication networks the Operational Expenditures (OpEx) are becoming of greater relevance. Within the OpEx the cost related to the power consumption and the ﬂoor space (footprint) rent are the most inﬂuential parameters. In this work, we compare the Total Cost of Ownership (CapEx+OpEx) of ﬁxed and ﬂexible grooming architectures employing single or mixed line rates, and evaluate its dependence with the trafﬁc pattern. Keywords: grooming, CapEx, OpEx, power consumption, footprint requirements.
