LightRiver, Infinera, complete multi-vendor interop demo
on Infinera’s ICE-X intelligent coherent pluggable technology and LightRiver’s netFLEX® Transport Domain Orchestration and Control Software combined with Infinera’s Intelligent Pluggables Manager (IPM) software, providing seamless multi-vendor network automation. The multi-vendor demonstration illustrates how LightRiver’s netFLEX® along with Infinera’s IPM can enable seamless
Infinera and LightRiver have announced the successful completion of a multi-vendor interoperability technology demonstration that leverages the latest generation of coherent pluggable solutions and validates how network orchestration can provide substantial improvements in network efficiency and enable new high-speed business services. The demonstration is based
FTTX PON solution. Infinera says the demonstration validates how network operators can leverage next-generation coherent pluggables to provide significant improvement in network efficiencies and expand network capacity by as much as 40 times, while also delivering new high- speed business services to currently underserved remote rural areas, including over single-fibre FTTX PON infrastructures.
network operation of multi-vendor networks leveraging the efficiencies of intelligent coherent pluggable solutions in conjunction with the latest generation of routers and FTTX PON solutions. The demonstration includes Infinera’s ICE-X line of intelligent coherent pluggables deployed in third-party host devices, including routers from Juniper Networks operating over a Smartoptics open ROADM system and the leading
Sumitomo cuts transmission loss in optical cables

wavelength of 1550 nm, this makes it the world’s lowest transmission loss for terrestrial cables. The cables have been selected for a wide-area DCI project connecting data centre clusters in Tokyo, Kanagawa, and Chiba, and the delivery has been completed. The outstanding low-loss performance of these cables enables to construct extremely low-loss transmission links including a 157 km-long section with the total loss of as low as 36 dB after deployment (including splice and connector losses). This will allow for high- capacity data transmission between data centres and reduce the number of optical repeaters, realising reliable transmission links with reduced overall system costs.
Sumitomo Electric Industries, Ltd, says it has improved the transmission loss of terrestrial optical fibre cables using PureAdvanceTM-110, a pure-silica-core, low- loss, large effective-area (Aeff) fibre. These cables have been selected for a data centre interconnect
Aqua Comms, Meta, Microsoft, and Vodafone have announced the completion of the Amitié subsea cable system, the first to directly connect Boston to Europe and Bordeaux to North America. The 6,783 km trans-Atlantic system, which was built by Alcatel Submarine Networks, has landings in Lynn, Massachusetts; Widemouth Bay, England; and Le Porge, France. With 16 fibre pairs and 400 Tbps, Aqua Comms says Amitié is the highest capacity transoceanic communications cable ever deployed. The system includes a
branching unit 860 km from France and 650 km from the UK. The device allows the owners to switch either individual optical wavelengths between different landings or the full fibre capacity via two different types of switching technologies. Amitié is now fully commissioned and tested and was handed over to Aqua Comms, Meta, Microsoft, and Vodafone in July 2023. The system was constructed under a Joint Build Agreement between the four partners, who worked together in close cooperation with the supplier and the landing providers.

completed. To achieve even lower transmission loss, Sumitomo Electric applied ultra-low-loss pure-silica-core fibre technologies. As a result, the transmission loss of optical fibre cables using PureAdvanceTM-110 has been improved from 0.17 dB/km to 0.16 dB/km or below. Sumitomo says that given a typical value at a
