A complete, realistic integrated system is investigated, consisting of directly spliced 7-core MCF, cladding-pumped 7-core amplifiers, isolators, and couplers. The system is demonstrated in a 16QAM C-band WDM scenario over 720 km.
We demonstrate the first 1-Pb/s unidirectional inline-amplified transmission over 205.6-km of single-mode 32-core fiber within C-band only. 96-Gbaud LDPC-coded PDM-16QAM channels with FEC redundancy of 12.75% realize high-aggregate spectral efficiency of 217.6 b/s/Hz.
We demonstrate 32-core dense space-division multiplexed (DSDM) unidirectional transmission of PDM-16QAM 20-WDM signals over 1644.8 km employing a low-crosstalk single-mode heterogeneous 32-core fiber in a partial recirculating-loop system.
The operation of multi-domain and multi-vendor EONs can be achieved by interoperable Sliceable Bandwidth Variable Transponders, a GMPLS / BGP-LS-based control plane and a planning tool. This paper reports the first full demonstration and validation this end-to-end architecture.
The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable, for example the data rate or channel spacing, requires an evolution of the node architecture. To fully benefit from elasticity, the data plane should evolve...
This paper reports on the general architecture for a sliceable bandwidth variable transponder as discussed within the IDEALIST European project. Support for super-channels (optical connections with several adjacent sub-carriers) and slice-ability (super-channels generated together but independently routed in the network towards different destinations) is guaranteed. For illustrative purpose some driving...
This paper describes the general architecture for a sliceable bandwidth variable transponder as identified within the IDEALIST European project. The capability of generate super-channels (optical connections with several adjacent optical sub-carriers) and the slice-ability (super-channels generated together but independently routed in the network towards different destinations) are the key elements...
We optimize the FEC-OH of dual-carrier PM-16QAM 400Gb/s super-channel, considering the tradeoff between FEC net coding gain and performance penalties due to limited DAC/ADC bandwidth. At optimum FEC-OH (−29%), WDM transmission of 400Gb/s super-channel over 2150km LAPSCF is experimentally demonstrated.
We experimentally evaluate filtering penalties due to channel add/drop in optical nodes for 32GBd PM-8QAM and PM-16QAM signals, transmitted over 37.5GHz WDM grid. Optical spectral shaping is employed in each node to mitigate optical filtering penalties.
We experimentally demonstrate long-haul WDM transmission of 36GBaud four-subcarrier Terabit PM-16QAM super-channel. Digital pre-distortion enables ∼50% reach improvement for both LAPSCF and SSMF fiber-types, with maximum recorded reach of 2272km and 949km, respectively.
We review the latest developments and challenges in the field of digital signal processing for state of the art and future optical coherent communications for 400Gb/s and beyond.
107-Gb/s full-ETDM transmission is shown over a 160-km field installed fiber link. A high tolerance towards narrowband optical filtering is demonstrated using vestigial sideband modulation to minimize the spectral width.
A novel emulator model enables deterministic generation of first and second order PMD without higher orders. It was used to determine PMD tolerance of different modulation formats, revealing substantial differences in PCD and DEP tolerance.
When asked about his processes in designing a new airplane, Burt Rutan responded: "...there is always a performance requirement. So I start with the basic physics of an airplane that can get those requirements, and that pretty much sizes an airplane... Then I look at the functionality... And then I try a lot of different configurations to meet that, and then justify one at a time, throwing them...
We prove the capability of adaptive PMD compensation with integrated optical FIR-filters in lattice structure and an electrical spectrum monitoring based feedback signal in 40 Gb/s experiments. Moreover we present the combined PMD and GVD compensation.
