Journal ArticleDOI
Influence of polarization state, baud rate and PMD on non-linear impairments in WDM systems with mixed PM (D)QPSK and OOK channels
TL;DR: It is found that the nonlinear impairments are highly dependent on relative SOP between the PM (D)QPSK and neighbouring OOK channels, and with increasing values of PMD this dependence decreases, and non-linear tolerance improves.
Proceedings ArticleDOI
Exploring Channel Probing to Determine Coherent Optical Transponder Configurations in a Long-Haul Network
Kaida Kaeval,Danish Rafique,Kamil Blawat,Klaus Grobe,Helmut Grießer,Jorg-Peter Elbers,Piotr Rydlichowski,Artur Binczewski,Marko Tikas +8 more
TL;DR: Channel probing is used to determine the best transponder configurations for spectral services in a long-haul production network and an estimation accuracy better than ±0,7dB in GSNR margin is obtained for light paths up to 5738km.
Proceedings ArticleDOI
Nonlinear performance of 200Gb/s, 400Gb/s and 1Tb/s PM-16QAM superchannels in dynamic WDM traffic scenario
TL;DR: Flex-grid network upgrade scenarios are evaluated and it is shown that optical channel power should be assigned with knowledge of existing neighboring traffic to achieve best performance in WDM transmission.
Proceedings ArticleDOI
Digital non-linear compensation for high-speed long-haul transmission
TL;DR: An overview of the most promising techniques to increase the non-linear tolerance of optical signals by means of digital signal processing is presented, show some examples of their application and outline the status of research on this important topic.
Proceedings ArticleDOI
All-optical OFDM and distributed Raman amplification: Challenges to enable high capacities and extend reach
Fatima C. Garcia Gunning,P. Frascella,Cleitus Antony,Simon J. Fabbri,Danish Rafique,Stylianos Sygletos,Paul Gunning,Dermot Reidy,William McAuliffe,Derek Cassidy,Andrew D. Ellis +10 more
TL;DR: It is argued that, in an energy constrained high-capacity transmission system, direct detected all-optical OFDM with `ideal' Raman amplification is an attractive candidate for metro area datacentre interconnects with ~100 km fibre spans, with an overall energy requirement at least three times lower than coherent detection techniques.
