Fujitsu's TransLambda delivers 3X optical capacity in C-band

Fujitsu Network Communications unveiled TransLambda technology,  an ultra-high capacity, wavelength-division multiplexing (WDM) multiband transmission system (MTS) that substantially expands the transmission capacity of optical fiber networks without deploying new L- and S- band dedicated transceivers.

Fujitsu's TransLambda packs multiple transmission bands into a single fiber using all-optical wavelength conversion (AOWC). TransLambda enables up to three times the capacity for data center interconnect (DCI) and long-haul transport networks. Specifically, TransLambda fiber capacity multiplier technology offers ultra-high capacity — up to 76.8Tb/s of data using 192 channels at 400G speeds per 75GHz channel — in a plug-and-play blade using C-band transponders.

The company said this 3X boost is particularly crucial for those applications where C-band transmission is the only available option for the foreseeable future, such as optical links that use direct-attach or transponder-attach ZR/ZR+ pluggable coherent optics.

The Fujitsu TransLambda Test Kit, which is currently being used in customer lab trials, is offered in a single blade configuration that can be used with any legacy WDM network architecture including multi-vendor systems.

“TransLambda technology is just the latest in a line of innovations from Fujitsu to achieve the highest network speed and capacity as cost-efficiently as possible, helping our customers gain true competitive advantage in today’s demanding marketplace,” said Paul Havala, vice president of global planning at Fujitsu Network Communications. “Our TransLambda fiber multiplier approach is a much more cost-efficient way to achieve significant capacity increases without installing L-band equipment, addressing cost and operational overhead while seamlessly integrating into existing network architecture to fully leverage deployed fiber assets.”

Arista announces OSFP Optical Line System for 400G

Arista Networks announced an optical line system in an OSFP (Octal Small Form-factor Pluggable) module form factor. The OSFP-LS line system was purposely conceived and designed for the support of 400G ZR digital coherent optics.

The Arista OSFP-LS collapses legacy optical line systems into an OSFP module which can be plugged into any Arista OSFP port, supporting up to 8 DWDM wavelengths with a single fiber pair, and delivering up to 3.2Tbps of DCI traffic over 100km.

Arista describes its OSFP-LS as a highly compact, low power and cost-effective solution for increasing bandwidth between data centers without the need for external optical line systems. Features also include automatic setup with no operator configuration required.

“The OSFP-LS is far easier to deploy than conventional external line systems that require their own power feed and control management software while consuming valuable rack space. Interconnecting two data center sites with DWDM becomes as simple as connecting two switch ports,” said Hacene Chaouch, Distinguished Engineer, Arista Networks.

The OSFP-LS is in testing and qualification now with availability in 2H 2020.


Ciena and Arista conduct 400GE interoperability test

Ciena and Arista recently completed an interoperability test of their respective 400GE transport solution and high density native 400GE router.

The interoperability test leveraged Ciena’s Waveserver 5, powered by WaveLogic 5 Extreme (WL5e) coherent optics, and Arista’s 7280DR3 to show how high-bandwidth 100GE and 400GE client traffic can be maximized across any distance, supporting fiber capacities up to 38.4Tbps. The testing included successful transport of two 400GbE client signals from Arista’s 7280DR3 across a single WL5e 800G wavelength on Ciena’s Waveserver 5, demonstrating the most capacity achieved in the industry over a single set of electro-optics.

Ciena’s Waveserver 5 supports up to 12.8Tbps in a compact 2RU footprint and enables providers to maximize transport of high-bandwidth 100GE and 400GE client traffic across any distance using minimal hardware. Arista’s 7280DR3-24 router supports 9.6Tbps of throughput with 24x400GE ports in an ultra-compact 1RU footprint.

ONF’s Stratum Open Source Switch OS runs on TIP's Cassini

Stratum, the open-source switch operating system software developed by the ONF, is now available on Cassini packet optical transport hardware from TIP.

Cassini is a network switching platform with integrated optical transponders that is developed as a project by the Telecom Infra Project (TIP).

Stratum is a thin switch OS for data center white box switches supporting SDN interfaces, including P4, P4Runtime, gNMI and OpenConfig.



Stratum’s capabilities have now been extended to support configuration and management of optical parameters including wavelength, modulation and optical power. These new capabilities enable Stratum to be deployed on the white box Cassini platform. Stratum on Cassini now enables a completely open SDN-native solution for addressing Data Center Interconnect (DCI) use cases.

The ONF notes that its ODTN project has already demonstrated end-to-end orchestration of a network of Cassini-based systems in field trials. The demonstration leveraged the open source ONOS control plane from ONF and the open hardware from TIP; it also relied on proprietary embedded software running on the Cassini platform. It can serve both as a spine for “leaf-spine” type architectures within the datacenter, and as a packet optical transponder for the inter-datacenter connections. The four Cassini systems replace what would otherwise be 8 distinct devices: 4 spine switches and 4 packet optical transponder systems.  This converged design enables operators to deploy simpler solutions at a much lower cost, both in terms of Capex and Opex.




ONF's Stratum Project goes Open Source

The ONF's Stratum SDN project has been released as open source under the Apache 2.0 open source license.

Stratum is an open source, silicon-independent switch operating system for software-defined networks that runs on a variety of switching silicon and various whitebox switch platforms.

The ONF said the goal of Stratum is to avoid the vendor lock-in found with today’s data planes that feature proprietary silicon interfaces and closed software APIs that tend to lock operators into using a specific hardware technology. The strict contractual relationship of a P4-based interface between a Stratum switch and its controller ensure that the switch can be swapped with a spectrum of alternatives (even those with different switching silicon from a diversity of vendors) without need for controller modification or network retest and validation.  Never before has it been possible to grow and upgrade installations and adopt the latest advancements in switching silicon at the speed of cloud development.

Stratum also exposes a set of next-generation SDN interfaces including P4, P4Runtime, OpenConfig, gNMI and gNOI, enabling programmability of forwarding behaviors, zero-touch operations and full automated life-cycle management. This makes Stratum a key enabler for ONF’s next-generation SDN initiative.

“Bringing project Stratum to open source is an important milestone in furthering the ONF’s open networking movement,” said Guru Parulkar, Executive Director, ONF. “Stratum provides a consistent set of northbound Next-Gen SDN interfaces even as it runs on a wide selection of hardware platforms leveraging a variety of switching silicon. As such, Stratum is becoming the common substrate for ONF’s Next-Gen SDN stack, enabling rapid innovation, zero touch operations and a robust hardware ecosystem.”

  • ZTE’s market share increased two percentage points in 2019 due to a strong sales recovery from last year’s U.S. ban. This lifted ZTE’s share across all regions with the exception of North America where ZTE no longer has meaningful revenue.
  • Ciena’s market share increased one percentage point in 2019 driven by the company’s rising sales in data center interconnect applications, driven by the success of its Disaggregated Transponder Unit or stackable systems sales.
