OTN transport provides excellent performance in traditional transport use cases, but standard OTN has disadvantages that hamper its use in networks carrying 5G, IoT, and private line traffic.
Huawei’s OTN offering aims to future-proof OTN and promote its use in a wider set of use cases.
With operators facing limitations in flexibility, granularity, and traffic differentiation in their OTN networks, Huawei is introducing extensions to the technology – called Liquid OTN. It aims to improve OTN’s applicability to traffic types like 5G transport, IoT, private lines, and AR/VR, but also with a view toward making the networks more flexible and amenable to automation.

The Next Generation Optical Forum (NGOF) was founded in 2017, gathering predominantly China-based telcos, academic institutions, equipment vendors, and component/chip suppliers; in 2020, the association wants to accelerate its work on the requirements for future optical networks.
The current focus of the NGOF is high-quality private line technology and standards, the new generations of OTN, and 5G transport-related technologies.
Who Is the NGOF?
Founded in 2017, the NGOF has around 40 members, including network operators, system vendors, component and chip vendors, testing equipment vendors, and academic organizations. Most members are Chinese or China-based; however, some (especially on the vendor and component side) are based outside of China. Continue reading “NGOF: Taking Optical Networks to the Next Level”→
After forming its telco business to take a piece out of the NFV cake several years ago, VMware has continued to gain momentum with CSPs.
VMware is likely to expand its presence in telco networks as its core products develop to address key cloud-native transformation priorities.
At the onset of the NFV revolution, most industry players reached a consensus that the virtualized telco of the future will become a DevOps shop, running mainly on open source software components. However, even though it may work for the largest telcos, this blueprint is far from universal – as exemplified by the telco business momentum shown by one of the largest global ISVs, VMware. At the VMworld Europe event in Barcelona on November 3-7, VMworld executives put a special emphasis on their telco business, which nowadays encompasses three primary focus areas: building the telco cloud, optimizing the edge, and optimizing the radio. VMware now counts more than 100 telco cloud and service assurance clients in production serving over 800 million mobile subscribers. Telco – the only vertical business within VMware – figured prominently in the keynotes as well, with the launch of VMware’s ‘Project Maestro’ telco cloud orchestrator as one of the main points of CEO Pat Gelsinger’s presentation.

• Webscales, ICPs, and enterprises are using DCI solutions to provide high-quality, practically unlimited connectivity for their data centers, while controlling their costs through building up their own infrastructure.
• DCI vendors need to develop their solutions considering not only the connection capacity requirements, but also the increasing demands on O&M simplification, intelligence, and security.
DCI solutions have evolved, driven by the incessant growth of cloud, which will continue well into the future. According to GlobalData’s market sizing and forecast, the global cloud ecosystem expanded 24% in 2018 and reached US$ 290 billion; it will continue to grow with CAGR of 25.3% over the forecast period, reaching US$720 billion in 2022. The first use for DCI has been in providing point-to-point connectivity for large centralized data centers. But as data centers keep getting deployed throughout the network footprint – all the way to the network edge itself in edge computing installations – the demand for simple, high-performance optical solutions keep growing as well.

Support from AT&T, Verizon, and Rahi Systems is a big thumbs up for both Lumina in particular and hardware-agnostic SDN in general.
The fact that Lumina needs external funding to grow shows that growing organically in the SDN business is still difficult.
At its launch last year as Brocade’s networking business spinoff, Lumina Networks’ value proposition focused on building a service-oriented business, catering open-source, hardware-agnostic SDN solutions to telcos and enterprises. Last week’sannouncement of the company’s successful $10 million funding round (of which $8 million was from Verizon Ventures) validates this value proposition and underlines the confidence large telcos like AT&T and Verizon have in the company’s solutions and business model.

PCS Maximizes Fiber Utilization: The PSE-3 DSP relies on PCS modulation to increase available bandwidth per fiber close to its theoretical maximum.
PSE-3 Simplifies Network Operations: PCS enables the PSE-3 to tune its wavelength capacity from 100G to 600G, using a single modulation format, baud rate, and channel size.
Nokia’s new Photonic Service Engine 3 (PSE-3) is designed to improve optical performance, flexibility, and programmability across a wide range of wavelength capacities. To achieve this, the new DSP chipset utilizes probabilistic constellation shaping (PCS) – a modulation technique which improves optical reach performance by approximately 1 dB, or roughly 25% (compared to the most advanced optical systems today). This brings the optical system performance, according to Nokia, within a fraction of a dB of Shannon theoretical limits.
