We report for the first time an ultra-wideband coherent (UWB) WDM transmission over a 70
km standard single mode fibre (SSMF) solely using a multistage discrete Raman amplifier …

Capacity enhancement by utilising the unused spectral bands of the low-loss optical window
of standard single-mode fibre (SSMF) is a cost-effective solution for meeting the future …

Ultra-wideband transmission utilizesbandwidths beyond the standard C-band to enable
significant network capacity upgrades. Upgrading the standard C-band to a C+ L-band …

We report a first-time ultra-wideband transmission through 70-km long fiber enabled by
hybrid amplifier based on bismuth-doped fiber and discrete Raman amplification. The …

We experimentally investigated and demonstrated an ultralow noise hybrid amplifier that
