Fiber-optic multi-band transmission (MBT) aims at exploiting the low-loss spectral windows
of single-mode fibers (SMFs) for data transport, expanding by the available bandwidth of C …

Spatial-division multiplexing (SDM) and band-division multiplexing (BDM) have emerged as
solutions to expand the capacity of existing C-band wavelength-division multiplexing (WDM) …

Multi-band (MB) optical transmission promises to extend the lifetime of existing optical fibre
infrastructures, which usually transmit within the C-band only, with C+ L-band being also …

We compare the networking merit of two possible multiplexing techniques on top of
wavelength division multiplexing to enlarge transmission capacity: the band division …

The adoption of open optical networks (OONs) requires the development of open and

We investigate cost-efficient upgrade strategies for capacity enhancement in optical
backbone networks enabled by C+ L-band optical line systems. A multi-period strategy for …

Nowadays, the fiber spectrum is only partially exploited, ie, mainly in the C-band and more
recently in the C+ L-band, where the fiber attenuation profile experiences the minimum …
