Abstract

Current forecasts indicate that the fastest growing IP-traffic is in metro and data center interconnect (DCI) [1]. The exploitation of the entire low-loss spectrum of single-mode fibers (SMF) (from 1260 nm up to 1620 nm) was proposed to avoid the predictable capacity crunch and the eventual need for a new fibre infrastructure roll-out. First analytic result considering multi-band (MB) transmission (from O- to L-band) hint an achievable traffic load exceeding 200 Tb/s for a 500 km link in a single SMF [2].

In case of short-reach links (≤ 40 km), the total capacity is > 500 Tb/s/fiberwhich is an enormous increase with respect to current commercial C+L-band systems. Moreover, even for distances around 80 km, the total fiber capacity is still in the order of 400 Tb/s/fiber. C-band represents just a small part of the capacity available in the fiber. Exploiting the remaining low-loss bands increases the potentialities the already deployed optical fiber infrastructure. However, sophisticated techniques are needed to efficiently plan the line system.
