Infinera tests point-to-multipoint coherent pluggable with Sumitomo Electric

Infinera and Sumitomo Electric completed the first testing of point-to-multipoint coherent pluggable transceiver technology in Japan.

The XR optics point-to-multipoint integration testing , which was conducted in Infinera’s Tokyo lab facilities, was implemented over an existing PON network using Infinera ICE-X 100G and 400G coherent pluggables transceivers hosted in the Sumitomo Electric FTU 9100 metro/access aggregation switch. The test showcased how XR optics can increase capacity and reach by orders of magnitude by overlaying coherent wavelengths over existing single-fiber (bidirectional) PON networks.

The testing included demonstrations of the following: high-speed business services over existing single-fiber PON infrastructure, simplified network aggregation for emerging services and applications such as 5G and edge computing, and efficient point-to-multipoint metro traffic transmission over existing optical line systems. These demonstrations underscore the value XR optics bring to service providers to cost-efficiently increase capacity and expand service offerings. 

“This industry-first testing in Japan reinforces Infinera’s dedication to innovation and our commitment to solving our customers’ toughest challenges, especially as bandwidth growth at the network edge drives demand for new approaches to metro and access transport architectures,” said Naosuke Akiyama, Japan Country Manager, Infinera. “We are excited to partner with Sumitomo Electric to showcase a wide variety of cost- and power-efficient pluggable optical solutions with unique levels of intelligence, automation, and programmability.”

“We have taken a big step toward optical network innovation by collaborating with Infinera on its XR optics technology, which enables point-to-multipoint network topology,” said Kazutaka Kawamoto, General Manager, Information Network R & D Center, Sumitomo Electric.

Graphiant: 2023 State of Network Edge Survey

Enterprises have rapidly adopted "as-a-service" models for applications, storage and computing and are now poised to do the same for Network-as-a-Service (NaaS), according to a recent survey conducted by Eleven Research on behalf of Graphiant.

The survey, which collected 200 responses from large enterprises in North American, found that MPLS and SD-WAN are failing to meet the needs of emerging network edge use cases.

 "This happens every 10-11 years," says Khalid Raza, founder & CEO of Graphiant. "I saw this in 2000 while pioneering MPLS at Cisco. I saw it when I co-founded Viptela in 2012. And now It’s time again for a new approach to the network edge.”

 Respondents called out three critical uses cases:

  • Enterprise connectivity has changed in recent years, with a surge in remote workers, remote offices, and IoT.
  • Cloud connectivity is the second use case that stretches enterprise capabilities.
  • And trends such as digital transformation and the service economy are pushing enterprises to connect more often with customers and partners.

"These new use cases are tough for MPLS and SD-WAN," says Robert Spangler, Senior Network Engineer at Ballad Health. "MPLS is too slow to deploy and change and far too expensive. And SD-WAN can't handle that number of tunnels."

In March, Graphiant, a start-up based in San Jose, California, announced a $62 million Series B funding round for its network edge service that promises to shake up the established framework of VPNs, including MPLS and SDWAN.

Graphiant provides a next-gen network edge that combines the performance and security of MPLS with the agility of “as-a-Service” delivery. The company says it can deliver SLA-class performance at up to 70% less cost. 

Edgecore Networks refreshes Gigabit Ethernet Access Switch

Edgecore Networks introduced its newest generation L2+/Lite L3 Gigabit Ethernet Access Switch with 10G uplinks designed for ISPs and Multiple System Operator (MSOs) to provide home users Triple-play services and business users Virtual Private Network services with up to Gigabit bandwidth.

Nokia and Claro deploy private 4.9G in a maritime terminal in Colombia

Claro Colombia has deployed a private 4.9G wireless network and edge computing solution at Sociedad Portuaria Puerto Bahía in Cartagena, Colombia, using the Nokia Digital Automation Cloud (DAC), including the Nokia MX Industrial Edge.

The installation, which delivers high bandwidth and low latency, will reliably and securely connect hundreds of workers, sensors, equipment, vehicles and cargo.

Nokia DAC will be the key enabler of Puerto Bahía's digital transformation journey, which will begin with automation in the hydrocarbons terminal area. One of the more innovative use cases to be implemented is the tracking of up to 20,000 vehicles at peak capacity. Nokia DAC will also provide connectivity between TOS (Terminal Operation Systems) and personnel, and between cranes in docks and yards to optimize operations.
