SUNNYVALE, Calif. & LITTLE ROCK, Ark. – Infinera and Windstream, a leading provider of advanced network communications, today announced the completion of a live network trial that successfully achieved 800 gigabits per second (800G) single-wavelength transmission over 730 kilometers (km) across Windstream's long-haul network between San Diego and Phoenix. In addition to the industry-leading real-world performance at 800G, Windstream and Infinera set another industry record by looping back the signal to achieve a 700G transmission over 1,460 km. The trial was performed using Infinera's fifth-generation coherent optical technology, ICE6 (Infinite Capacity Engine), equipped in a Groove (GX) Series platform over industry-standard G.652-compliant SMF-28 fiber, with both signal rates achieving a performance level that met Windstream's production network deployment standards.
The results of the trial mark a major milestone in optical networking by demonstrating that ultra-high-speed optical transmissions, such as 700G and 800G, powered by Infinera's ICE6 optical engine and Windstream’s high-performance fiber network, can be deployed in real-world network applications over significant distances. This will enable emerging 400 Gigabit Ethernet (400 GbE) services to be supported over longer distances within the Windstream national network. High-performance, high-speed transmission will also enable network operators like Windstream to realize increased efficiency in cost per bit and power per bit, as well as increased capacity per fiber by as much as 70 percent compared to third-generation (400G) coherent technology and by as much as 35 percent compared to fourth-generation (600G) coherent technology.
The industry-leading 700G and 800G transmission performance was enabled by advances in Nyquist subcarriers, a pioneering innovation developed by Infinera's Optical Innovation Center (OIC). Unlike competing technologies, Nyquist subcarrier-based solutions enable superior performance by mapping the traffic into tightly packed, lower-baud-rate digital subcarriers within a single optical carrier. In addition to providing significant performance benefits on their own, subcarriers also amplify the benefits of other innovations from Infinera's OIC such as 64QAM long-codeword probabilistic constellation shaping and dynamic bandwidth allocation that now can be applied to each subcarrier independently.
Overall peak usage on US cable networks continues to flatten out and even decline slightly, but sustained higher levels of usage on the upstream path have persisted, according to the latest data from the NCTA.
Over the next two years, approximately 60% of service providers (both large and small) will adopt virtualization on a wide scale across their networks, according to the latest survey report from Ovum. Why are providers making these moves? Is there an easy way to start?
Learn how and why service providers are using virtualization to transform their networks. This webinar will look at how providers are leveraging virtualization to create more flexible and agile networks while also providing a better customer experience. Expert speakers from netElastic and Heavy Reading will address the industry drivers for network virtualization, the benefits that can be realized, the challenges to face and the results of virtualization being achieved by providers today.
Key topics will include:
Current network infrastructure and the move to virtualization
Benefits and challenges of network virtualization
How providers can get started
Service provider success stories: the decision to virtualize, the solution, and results
