“In markets around the world 5G is driving transport network upgrades that will mark a milestone in digital transformation. IP routing will have a key role to play due to its scalability, flexible resiliency and the operational simplicity of a single end-to-end control plane. Providing an alternative to traditional monolithic architectures, however, disaggregated routing enables network operators to gain the traditional benefits of IP routing while also benefiting from minimized vendor lock-in, competitive pricing, more choice, faster innovation and cost-effective scaling, all with the potential to significantly lower both CapEx and OpEx.”

“Infinera’s Bennett credits the group’s success to two factors. One is Infinera's use of integrated photonic circuits, with all six lasers on the same substrate, rather than on separate chips. That makes it easier to lock laser wavelengths together to enhance performance. Doing so can be difficult in setups where the temperature of each separate chip drifts independently. The other factor is Nyquist shaping the subcarrier bands to reduce the bandwidth needed to extract the clock for signal timing.”

"Infinera makes the 'equipment that puts the light into the optical fiber,' [Geoff] Bennett explains. To hit data transfer rates of 20 percent over the capacity of the fiber, Bennett says they did two things. First, they implemented 'multiple wavelengths on a single optical chip, so that we could squeeze the individual wavelengths closer together, and get more wavelengths on the fiber,' he explains. 'And the second part is, each wavelengths is transmitted as a set of subcarriers that also allows tighter spacing.' So, while the pipe remained the same, they increased how much data could be sent through it in a given amount of time."

"As part of an ongoing partnership, Infinera’s fourth-generation Infinite Capacity Engine 4 (ICE4) optical engine is being rolled out across [Telstra’s] subsea infrastructure, with the aim of increasing the capacity, agility and reliability of the network. The companies calculated that ICE4 will increase Telstra’s fibre capacity by 160 per cent, with a 140 per cent increase in port density. Power consumption, meanwhile, is decreased, allowing Telstra to continually improve network services."

"The upgrade, announced on Monday, uses technology from US firm Infinera to upgrade its huge network of submarine cables. The overhaul will increase the capacity of the lines by 160 per cent, while also decreasing power consumption. That means Telstra’s cables – which run from Australia to various locations in the Asia Pacific region as well as the US – will be able to carry half as much data again as they do now."
"The new technology deployment will position Telstra to offer 200-Gbps wavelength services over its submarine cable infrastructure and improve reliability and flexibility, the partners say."
"Infinera says its HDEA design delivers several benefits. Using the sides of the box means that the platform supports 80 SFP+ interfaces, twice the capacity of competing designs. In turn, using MPO connectors simplifies the fibre management, benefiting operational costs. Infinera also believes that the platform’s overall power consumption has a competitive edge. Baldry says Infinera incorporates only the features and hardware needed. 'We have deliberately not done a lot of stuff in Layer 2 to get better transport performance,' he says. The result is a more power-efficient and lower latency design."
"Advances in open optical transport system architectures are creating ultra-dense, ultra-efficient IXP applications, including innovative 1 rack unit (1RU) modular open transport platforms for cloud and data center networks that can be equipped as muxponder terminal systems and as open line system (OLS) optical layer platforms. Purpose-built for interconnectivity applications, these disaggregated platforms offer high density, flexibility, and low power consumption. Designed to meet the scalability requirements of network operators now and into the future, innovations in OLSs include a pay-as-you-grow disaggregated approach that enables the lowest startup costs, reduced equipment sparing costs, and cost-effective scalability."

"Andres Madero, Director: Service Provider, Architecture & Business, Development at Infinera Latam, believes that Brazil's National Internet of Things (IoT) plan will require a cloud scale approach towards preparing the traditional transport infrastructure. 'The increment on the amount of terminal units to be incorporated by IoT in any of the verticals will represent a significant increase in the amount of bandwidth required in the network,' he says. 'Critical mission applications driven by IoT automation will also require these networks to focus not only on the amount of bandwidth delivered but also the quality (data delay) of the traffic.'"
"Infinera expects to deliver industry-leading growth and operating margins once it exploits the benefits of vertical integration across an expanded portfolio of platforms, said Fallon."
