“…Signal disturbance effects occurring in fiber optic cable are Hamming code, Reed-Solomon code, Bose-Chaudhuri-Hocquenghem code, etc. can be corrected using algorithms [32][33]. In DWDM systems, faults on channel cards with optical channel resources can be healed using a number of FEC algorithms, including carriers that can be corrected by FEC algorithms.…”

Bu çalışmada, telekomünikasyon alanında kullanılan DWDM sistemlerinde kalite metriklerinde en önemli parametrelerden biri olan FEC değerinin, DWDM sistemlerinde toplam 7 farklı metriğe karşı değişimi gözlemlenmiştir. Bu değişiklikler makine öğrenmesi algoritmaları ile analiz edilerek, canlı ağ değerlerine göre FEC parametresini etkileyen en önemli girdinin hangi parametre olduğu belirlenmiştir. Makine öğrenmesinde tahmin sonuçlarına göre en doğru FEC değerini veren algoritmayı belirlemek için vendordan bağımsız analizler yapılması hedeflenmiştir. Sonuç olarak; 3 farklı vendordan 945 canlı ağ değeri ile gerçekleştirilen bu analizde FEC değerini etkileyen en önemli parametrelerin kanal sayısı, fiber zayıflaması, fiber mesafesi olduğu belirlenmiş ve bu parametrenin en doğru şekilde tahmin edilmesi karar ağacı makine öğrenme algoritması ile sağlanmıştır.

“…Failure of the PON system must be mitigated due to the network's greater level of resiliency and reliability. Several architectures have been introduced to protect and restore the operation of WDM-PON [ 16 ]. C. Christodoulou et al presented tree-based topology for WDM–PON which suffers several disadvantages like TDM–PON.…”

“…To fulfill future demand, the different architecture of PON technologies has been carried out. Research and development in PON transceiver technologies, splitters, amplifiers, modulation, light amplification by stimulated emission of radiation (LASERS), OLTs, ONTs, optical fiber, EDFA and AWG are an essential part of the upcoming PON technology which must be considered for better throughput and long-distance communication [ 16 – 20 ]. Standardization of 10 gigabits per second (Gbps) TDM-PON architecture has been completed, and at 25 Gbps, TDM-PONs are near to standardization.…”

To fulfill the future demand for high data rate, novel research has been carried out which provides high-performance and secured communication from the optical line terminal (OLT) to the optical network unit (ONU). Results have been incorporated with simulations in optical simulation software called Opti-system. Gain and power estimation has been considered for long reach using wavelength division multiplexing passive optical network (WDM-PON). This method evolves with time and extends to mobile, local area, and metro area access networks. Finally, it has been predicted that the system data rate can reach (2.5 × 8) 20 gigabits per second (Gbps) up to a maximum of 80 km (km). The distance limit for larger data speeds (i.e., 5Gbps or 10 Gbps) was 80 km with a power of 30 dBm. A higher data rate of 40 Gbps per channel was achieved successfully at 30 km, i.e., a maximum data rate from 80 Gbps (10 × 8) to 320 Gbps (40 × 8) can be achieved with novel optimized WDM-PON architecture. Bit error rate (BER), quality (Q) factor, and eye height have limited within the acceptable range as per international telecommunication union (ITU) standards to achieve and fulfill the future demand of 5G (generation) or 6G-based applications at the last mile.

“…To satisfy the broadband capacity demand growth due to the wide applications of quantum networking, cloud computing, artificial intelligence (AI), internet traffic, data centers, big data, and 4K/8K video service, the access technology of fiber networks would be the best choice for data connection for the end-user [1][2][3]. Recently, optical access technologies include time-division-multiplexing (TDM) and wavelength-divisionmultiplexing passive optical networks (WDM-PONs) for high-speed and broad-capacity connection [4][5][6][7]. The TDM-PON is a point-to-multipoint (PtMP) and capacity-sharing access network.…”

In the paper, a dual-bidirectional ring-type wavelength-division-multiplexing (WDM) access network with downlink and uplink signal access simultaneously using a single fiber backbone in clockwise and counterclockwise directions, respectively. The proposed network architecture is simple and easy to implement via the designed remote node (RN) and optical line termination (OLT) modules, but it also can double the downlink traffic using the original WDM downlink wavelengths. The presented ring-type WDM network can also avoid the Rayleigh backscattering (RB) beat noise when the same wavelengths are applied as downlink and uplink channels concurrently. In the measurement, 50 km long-reach and 15 km short-reach fiber transmission lengths are achieved for the symmetrical 10 and 28 Gbit/s on-off keying (OOK) data access, respectively. In addition, based on the obtained power budgets of eight downlink WDM signals and network design at the forward error correction (FEC) threshold, 16 optical network units (ONUs) can be supported simultaneously.
