These features enable GFDM to be applied in long-haul coherent optical (CO) fiber transmission systems and to be combined with techniques such as polarization-division multiplexing (PDM) and wavelength-division multiplexing (WDM) to achieve Terabit-level transmission rate. However, the nonlinear effects introduced by long-haul optical fiber transmission evidently degrade the performance of WDM PDM CO-GFDM system. To the best of our knowledge, no existing researches have focused on nonlinear suppression for WDM PDM CO-GFDM system. Meanwhile, it is known that the sparse Volterra model based compensator can achieve similar bit error rate (BER) performance compared with traditional full Volterra compensator while maintaining lower complexity in nonlinear effect compensation. In this paper, we proposed 3rd-order sparse Volterra equalizer (SVE) for WDM PDM CO-GFDM system. We systematically introduced the principle of WDM PDM CO-GFDM system and deducted its nonlinear channel model based on 3rd-order Volterra series. Then we theoretically deduced the principle of sparse Volterra model, the structure of train sequence and the operation of estimating the coefficients of Volterra kernels using recursive least squares (RLS) algorithm. Simulation results demonstrate that, WDM PDM CO-GFDM system possess significantly lower BER compared with WDM PDM CO-OFDM system while achieve evidently higher net bit rate and net SE. Furthermore, for a 16-QAM modulated WDM PDM CO-GFDM simulation system with high data rate (eg. 1.6 Tbit/s sampling rate, 1.39 Tbit/s net bit rate and 138.74 bit/s/Hz net SE), the 3rd-order Volterra model based method improves the maximum transmission distance by approximately 33% compared to the 1st-order Volterra model for WDM PDM CO-GFDM system. Besides, while achieving similar BER performance, the computational complexity of the SVE is significantly decreased compared to the traditional Volterra compensator.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"93 ","pages":"Article 104214"},"PeriodicalIF":2.6,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we designed and numerically investigated for the first time two photonic crystal fiber (PCF) structures with CBrCl<sub>3</sub> as the core and fused silica as the cladding material for broadband SC generation. The propagation of the ultrashort pulse in the proposed fibers is modeled using the generalized nonlinear Schrodinger equation (GNLSE). The first fiber #F1 with a lattice constant (<em>Λ</em>) of 1.5 μm and filling factor (<em>f</em>) of 0.35, operates with a completely normal dispersion region. By pumping a pulse source with a wavelength of 1.56 μm, an input energy of 2.5 nJ, and a pulse duration of 90 fs in a 10 cm long fiber, an ultra-broadband, and highly coherent SC spectrum is produced, covering the wavelength range from 885.3 nm to 1953.8 nm (bandwidth of 1068.5 nm) with less than 10 dB spectral dynamic range. The second proposed fiber #F2 with a lattice constant of 2.0 μm and a filling factor of 0.3, exhibits an anomalous dispersion for wavelengths longer than 1350 nm. We obtained high coherence of the SC pulses in the range of anomalous dispersion over wavelengths from 912.2 nm to 3714.8 nm (bandwidth of 2802.6 nm) within a level of 45 dB.

OTN approach decouples customers from DWDM interfaces, ensuring that optical links work more efficiently. This concept is carried out at OTN switches, allowing traffic to be aggregated at intermediate nodes and directed to routes that are being underutilized. Planning OTN over optical networks is a complex problem involving a new equipment structure and logical architecture. This problem has arisen due to academia and industry’s interest in developing planning heuristics to reduce the cost of the network. This paper proposes an algorithm to perform OTN network planning to meet the services and their survivability requirements such as restoration and/or protection with the goal of reducing the network cost in terms of the number of OTN interfaces. We propose to use a multi-objective evolutionary algorithm to seek a solution that optimizes the project considering two conflicting decision variables: the number of used OTN interfaces and the average number of restored paths in case of double-link failures.

These advantages stem from their ability to flexibly and efficiently allocate resources, meeting modern communication networks’ dynamic and diverse demands. It is crucial to handle dynamic traffic loads and proactively manage the resources in an elastic optical network with a productive technique. Deep learning is an effective tool for complex data analysis and real-time decision-making. We address a model that integrates two deep neural networks: generative adversarial network (GAN) for data augmentation; and echo state network (ESN) for network’s requirement prediction. Furthermore, an optimization process is carried out for efficient spectrum allocation. The GAN provides a considerable and reliable quantity of data necessary to train the ESN model that could provide the desired output. The ESN model is further enhanced by optimizing the essential parameters, enabling it to learn diverse traffic patterns and anticipate unusual situations. By using a GAN-ESN approach, there is a substantial benefit in reducing latency, saving energy, and optimizing bandwidth allocation.
