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.
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.
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.
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.
