A paradigm shift in optical communication networks is proposed, with the introduction of a new ecosystem devices and components capability transforming current point-to-point (with their entailed, limiting, electrical aggregation) into flexible, scalable cost-effective point-to-multipoint networks. In architecture, which better aligns hub-and-spoke traffic patterns observed today's metro access network segments, interoperability across variety transceivers operating at different speeds...
The various topologies, traffic patterns and cost targets of optical networks have prevented the deployment end-to-end solutions across multi-domains, optimization network as a whole. consequent limitations in flexibility, scalability, adaptability will become increasingly important with new applications, such 5G/6G. Coherent transceivers based on digital subcarrier multiplexing (DSCM) are proposed to address these current constraints. In particular, DSCM allows (i) design high-capacity...
Acknowledging the predominantly hubbed traffic profile in metro, we apply digital subcarrier multiplexing techniques to 400Gb/s coherent pluggable optics, enabling a point-to-multipoint architecture which shows TCO savings of 76% over five-year period compared traditional based on ROADMs and point-to-point transponder.
Metro aggregation is one of the fastest growing segments in telecommunications terms data traffic. At intersection core and access, where coherent modules compete with direct detection technology, high capacity must be provided at low cost power, enhanced scalability flexibility. Real-life Telecom Italia Mobile metro networks are examined their design planning optimized. The analysis supported by techno-economics, which compares two solutions: traditional point-to-point (P2P) digital...
Point-to-multipoint (P2MP) optical coherent transceivers, which take advantage of digital subcarrier multiplexing, can greatly simplify design, planning and operations in next-generation high-capacity metro aggregation networks.In this paper, we investigate their utilization over two complex network scenarios: urban/industrial suburban/rural. We provide evidence that with P2MP technology, it is possible to achieve a 32% Capital Expenditure (CAPEX) savings compared the use traditional...
We propose combining point-to-multipoint coherent transceivers with a hybrid ROADM/filterless line system to enable flatter IP-architecture for cost-effectively scaling metro-core/access networks. Considering various traffic and link engineering scenarios, we show CAPEX savings exceeding 40%.
We report on the first real-time operation of coherent point-to-multipoint in high-speed fiber-optic communications. The broadcast and aggregation network consists a 400 Gb/s hub transceiver achieving post-FEC error-free communication with 4 × 100 leaf nodes, 5 – 50 km away.
We report a live-network demonstration of coherent point-to-multipoint technology for mobile fronthaul applications with total transmission capacity up to 100 Gbps per radio unit and 400 hub. show significant network simplification enabled by Nyquist subcarriers.
Coherent technology can be operated with independent digital subcarriers to realize point-to-point and point-to-multipoint optical networks. Enabled by configurable software management, it creates a simple, scalable, low-cost solution, compatible across network, vendors, generations.
We demonstrate real-time long-haul transmission with 400G digital subcarrier-multiplexed QSFP-DD coherent pluggable in a live production network, achieving record post-FEC-error-free reach of 1800-km 400G-16QAM, 80% longer than all previously publicly announced records.
