We present DFabric, a 12-rack, 180-server DCN using multiwavelength switching and interconnection. DFabric implements real-time network traffic and per-link utilization monitoring, and full-stack optimization by jointly optimizing optical switching and network flow routing.
We report the first successful real-time superchannel trials up to 5.6Tb/s over 359km and 2Tb/s over a live 727km link using 64GBaud flexible-rate transponders, demonstrating long term error-free performance and fast capacity turn-up of ∼2Tb/min.
First time successful 107.5 Gb/s MultiCAP 850 nm OM4 MMF transmissions over 10 m with multi-mode VCSEL and up to 100 m with single-mode VCSEL are demonstrated, with BER below 7% overhead FEC limit measured for each case.
We present a monolithic silicon photonic integrated circuit coherent modulator and receiver that works from 1260 to 1630 nm. We demonstrate 200-Gb/s unamplified 16-QAM transmission and long-range optical coherence tomography.
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.
We demonstrate a method to utilize the fiber Rayleigh scatter signature measured with C-OFDR exceeding the laser coherence length. The method overcomes the laser phase noise limitation by analyzing the local scatter power spectrum.
We demonstrate next-generation network upgrade scenarios using flexi-format (PM-QPSK→PM-64QAM) and flexi-rate (100G→300G) transmission over field-deployed fiber (762km). The back-to-back penalties are limited to ∼2.6dB, whereas after transmission, available margin in excess of ∼7.6dB is reported.
We measure inter-modal Rayleigh backscattering in few-mode optical fibers and compare the experimental results with simulation results obtained from newly-developed analytical formulae. Excellent agreement between theory and experiment allows investigation of mode-coupling dynamics using OTDR.
We directly measure the optimum length and the mode-dependent gain of multi-core and few-mode optical amplifiers using a swept wavelength interferometer operated in reflection mode. The technique requires only one space multiplexer and eliminates cut-backs.
We demonstrate a multidimensional tuning method of the silica whispering-gallery resonators. This method fully takes advantage of the unique structure of the microcapillary resonator to separately and easily tune its extinction ratio and resonance wavelength.
We review our recent experimental research work on mode-crosstalk in a transmission line composed of few mode fibers. We discuss the mode crosstalk at a splice point and in a fiber.
We present a single transceiver based modal characterization method for estimating the channel impulse response of MDM systems. Good agreements are found between the measured and simulated DGDs of a RCF supporting 5 mode groups.

Mode coupling in a step-index 2-LP-mode fiber has been experimentally studied using advanced S2 analysis. A wire-mesh is used to locally induce micro-bending and it is demonstrated that coupling coefficients can be extracted.
We demonstrate the potential of single-carrier serial line-rate 400Gb/s PM-64QAM transmission over short reach optical links. Performance below pre-FEC BER threshold is achieved over 328km for 96×516Gb/s PM-64QAM, employing EDFA-Raman amplification and LA-PSCF.
This paper proposes a YANG model to describe a sliceable transponder with variable rate, code, modulation formats, and monitoring capabilities. The model is introduced into NETCONF, which is experimentally demonstrated in a testbed.
ABNO's OAM Handler is extended with big data analytics capabilities to anticipate traffic changes in volume and direction. Predicted traffic is used as input for VNT re-optimization. Experimental assessment is realized on UPC's SYNERGY testbed.
We proposed a novel virtualized PON OLT architecture to realize flexible and cost-efficient PON systems, and evaluate the techniques proposed to suppress collision between upstream signals caused by the software-derived processing time jitter on MPMC.
