Pump RIN-induced impairments in unrepeatered transmission systems using distributed Raman amplifier

15 Tb/s Unrepeatered Transmission over 409.6 km using Distributed Raman Amplification and ROPA

15 Tb/s (150 x 120 Gb/s) unrepeatered transmission is achieved over 409.6 km (68.2 dB), corresponding to a record capacity-reach product of 6.14 Pb/s-km. We also demonstrate channel growth from 10 to 150 waves within 61 nm amplification bandwidth. OCIS codes: (060.0060) Fiber optics and optical communications, (060.1660) Coherent communications.

Low cost incoherent pump solution for Raman fiber amplifier

Characterisation of random DFB Raman laser amplifier for WDM transmission.

We perform a full numerical characterisation of half-open cavity random DFB Raman fibre laser amplifier schemes for WDM transmission in terms of signal power variation, noise and nonlinear impairments, showcasing the excellent potential of this scheme to provide amplification for DWDM transmission with very low gain variation.
