Infinera, Sumitomo achieve successful test of point-to-multipoint coherent pluggable transceiver

Infinera has partnered with Sumitomo Electric to test point-to-multipoint coherent pluggable transceiver technology in Japan. 

The testing showcased multiple optical transmission demonstrations and the role that XR optics technology can play in helping network operators in Japan keep pace with bandwidth growth. 

XR optics is Infinera’s coherent optical solution that was designed to help solve the challenges caused by the misalignment between network traffic patterns and the technology used to transport that traffic at the optical layer. The company says that the benefits include a reduction in total cost of ownership (up to and in some cases more than 70%), network simplification, and a higher level of network flexibility. As members of the industry’s Open XR Forum, Infinera and Sumitomo Electric are collaborating to accelerate adoption of intelligent coherent point-to-multipoint network architectures and drive standardisation of networking interfaces to ensure ease of multi-vendor interoperability and an open, multi-source solution ecosystem. 

The testing was conducted in Infinera’s Tokyo lab facilities and showcased, for Japan’s leading network operators, the XR optics point-to-multipoint integration over an existing PON network using Infinera ICE-X 100G and 400G coherent pluggable transceivers, hosted in the Sumitomo Electric FTU 9100 metro/access aggregation switch. It demonstrated that XR optics can increase capacity and reach by overlaying coherent wavelengths over existing single-fibre (bidirectional) PON networks. Demonstrations included: high-speed business services over existing single-fibre 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. 

Naosuke Akiyama, Japan Country Manager at Infinera says: “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. 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.”

Kazutaka Kawamoto, General Manager, Information Network R & D Center at Sumitomo Electric adds: “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. We look forward to this partnership leading to successes from the access to the core of the network for service providers.”
