Jisc is deploying Ciena’s 6,500 packet-optical platform powered by WaveLogic Ai coherent optics to provide unprecedented high-capacity 400G wavelength connectivity for the Janet Network.
Verizon has completed a successful field trial delivering live 400Gb/s Ethernet traffic on a single wavelength between MPLS Core routers over its packet-optical network.
The trial demonstrated the interoperability between equipment from two different suppliers – Ciena and Juniper – alongside the capability to quadruple the typical capacity carried on one wavelength.
Ciena, Telstra and Ericsson have collaborated to achieve speeds over 61.5GHz spectrum on Telstra’s transmission network in Melbourne. The companies say that this demonstrates the highest spectral efficiency per fibre pair ever achieved in a live environment.

HANOVER, MD – Ciena (NYSE: CIEN) and its partner Kapsch CarrierCom have been selected by ONTRAS Gastransport GmbH to implement a highly-reliable packet network. The network upgrade will enable Germany’s second largest gas transmission operator to introduce new security features to its facilities, improve data processing and address current and forthcoming industry legislation.
Ciena is expanding its packet networking portfolio with three new edge access and aggregation products and more capacity for its 8700 Packetwave edge aggregation platform. These new capabilities address 10 and 100 Gigabit Ethernet service delivery and aggregation to support new web-scale applications, like IoT, next-generation mobile and business Ethernet.
Multinational service provider BT has deepened its relationship with optical transport supplier Ciena, by renewing a five-year contract to deploy the vendor’s 6500 converged packet optical platform.
Ciena has been a supplier to BT since 2005 when it became one of the preferred suppliers to the operator’s 21CN deployment, the mega-project to migrate BT’s entire customer base from the existing UK public-switched telephone network (PSTN) to an Internet Protocol (IP)-based network.
Helen Xenos explains how telcos can unlock the full potential of their existing fibre connections, allowing them to offer bursts of additional capacity without having to physically build out the network
Optical networking is becoming smarter. Guesstimates and offline calculations are on their way out; to be replaced by real-time computation and machine learning applied to ‘big data’ generated by the network itself, which can be used to optimise performance in ways that weren’t possible before.
Ciena has introduced Waveserver Ai, bringing even higher capacity to its family of platforms for data centre interconnect (DCI) applications.
The new packet-optical platform exploits the WaveLogic Ai chip that the company unveiled last autumn (see Ciena embeds network monitoring in next-generation coherent chipset).
