Cisco completes Luxtera acquisition

Cisco completed its previously announced acquisition of privately-held Luxtera.

Cisco said it plans to incorporate Luxtera’s technology across its intent-based networking portfolio, spanning enterprise, data center and service provider markets.


Cisco to acquire Luxtera for silicon photonics -- $660M

Cisco agreed to acquire privately-held Luxtera, a developer of silicon photonic technologies, for $660 million in cash and assumed equity awards.

Luxtera, which is based in Carlsbad, California, focuses on silicon photonics process and packaging technologies for building integrated optics capabilities for webscale and enterprise data centers, service provider market segments, and other customers.

Luxtera leverages a hybrid integration approach wherein the photonics die forms the base of the transceiver chipset, while the light source and electronics die are attached on top. The company says its ability to integrate all optical components into a single silicon chip enables it to manufacture at wafer scale.

Cisco said the integration of Luxtera will broaden its portfolio of 100GbE and 400GbE optics. Cisco plans to incorporate Luxtera's technology across its intent-based networking portfolio, spanning enterprise, data center and service provider markets.

"With Cisco's 2018 Visual Networking Index projecting that global Internet traffic will increase threefold over the next five years, our customers are facing an exponential demand for Internet bandwidth," said David Goeckeler, executive vice president and general manager, Networking and Security Business at Cisco. "Optics is a fundamental technology to enable this future. Coupled with our silicon and optics innovation, Luxtera will allow our customers to build the biggest, fastest and most efficient networks in the world."

Cignal AI: Record cloud and colo optical hardware spending

Sales of optical equipment to the cloud and colo market, which includes Google, Microsoft, and Amazon, reached record levels during 2Q18 and were nearly a quarter of all North American operator purchases during 2Q18, according to the most recent Optical Customer Markets Report issued by networking component and equipment market research firm Cignal AI.

“While cloud and colo spending is still not near traditional telco demand for optical transport equipment, the balance is shifting. This is particularly true in North America, where cloud and colo operators now provide both technical and financial leadership to the supply chain,” said Andrew Schmitt, Directing Analyst at Cignal AI.

Some highlights:

  • Incumbent spending accounts for the largest share of all optical spending in the market. In fact, incumbent spending in China is as much as all spending by other incumbent operators worldwide, combined. Outlays by EMEA incumbents increased again in the most recent quarter.
  • Cable MSO spending in North America continues to be very strong and grew both quarter-over-quarter and year-over-year.
  • Ciena led other vendors in direct sales to the cloud/colo market led by strength from the WaveServer platform. Also, newly-combined Infinera and Coriant became the second largest supplier of optical equipment to these customers. Huawei also continues to grow its market share as a result of growing demand from Baidu, Alibaba, and Tencent.

Fujitsu demos 600G single wavelength optical transmission

Fujitsu Network Communications announced the first demonstration of flexible 600 Gbps single wavelength optical transmission using its 1FINITY T600 Transport platform. Software-provisioned data rates up to 600 Gbps per wavelength were achieved by a combination of high-performance components and electronics on the T600, maximizing spectral efficiency and reach for optimized network performance.

Specifically, Fujitsu publicly demonstrated error-free 600 Gbps transmission using 64QAM modulation at 69 Gbaud and 75GHz grid spacing in a point-to-point configuration. Service turn-up and onsite reprovisioning of signal rates and modulation formats were achieved among 300 Gbps, 400 Gbps and 600 Gbps. Fujitsu’s FSS2 system software provided OpenConfig over gRPC Network Management Interface (gNMI) for system configuration, streaming telemetry for network monitoring, and enhanced diagnostics. The demonstration showcased a 600G 64QAM live constellation shown on a Fujitsu-built vector signal analyzer.

The 1FINITY T600 is powered by third-generation digital signal processor (DSP) technology developed by NTT Electronics (NEL) in partnership with Fujitsu. The plaform delivers sophisticated and flexible modulation schemes and variable forward error correction (FEC). The advanced modulation flexibility provides optimum reach, capacity and power consumption, thereby enabling network operators to reduce cost per bit per kilometer for data center interconnect (DCI), metro, long-haul and submarine applications.

“At OFC 2018, Fujitsu was the first optical vendor to exhibit 500G per lambda,” said Rod Naphan, Deputy Head of the Network Products Business Unit at Fujitsu. “This week’s public demonstration of 600G further validates our leadership in next-generation coherent technology and positions us to bring the 1FINITY T600 to market in 1Q19.”

The Fujitsu 600 Gbps single wavelength optical transmission demonstration occurred during the NANOG 74 conference in Vancouver, British Columbia, on October 1-3, 2018.

NTT demos 118 Tbit/s transmission on multi-core fibre

NTT, together with six partners, KDDI Research, Sumitomo Electric Industries, Fujikura, Furukawa Electric, NEC and Chiba Institute of Technology (CIT), announced a demonstration of what is claimed as the highest transmission capacity of 118.5 Tbit/s using a multi-core fibre with four optical paths within the same diameter as currently used fibre.

NTT noted that a conventional glass diameter of 125 µm in accordance with the international standard enables the use of existing fibre fabrication and optical connector technologies. The demonstration is designed to validate the concept of multi-core fibre-based long-haul and high capacity transmission system comprising multiple vendor technologies and advance the application of multi-core fibre technology.

In the new fibre, 4-5 cores can be arranged within a 125 µm diameter while maintaining the same transmission quality as current optical fibre, with a 316 km multi-core transmission line realised with a 0.21 dB/km average loss, concatenating standard diameter multi-core fibre with 4 cores fabricated by multiple vendors.

As part of the new design, Sumitomo Electric, Fujikura and Furukawa each fabricated a multi-core fibre with 4 cores and more than 100 km length. All multi-core fibres can be used in the 1260 to 1625 nm wavelength region and provide similar transmission properties to current SMF with mode filed diameter at 1550 nm of 9-10 µm).

The fabricated multi-core fibres were divided into a 20-40 km sections and three transmission spans with a length of 104-107 km were re-constructed by splicing the multi-core fibres provided by different vendors. A satisfactory low loss comparable to conventional SMF was achieved, with average loss of four cores in each span 0.22 dB/km or less, including splicing losses.

In addition, three multi-core optical amplifiers fabricated by NEC, KDDI Research, NTT and Furukawa were inserted at each end of three spans to compensate the signal attenuation. Cladding pumping type multi-core optical amplifiers designed to reduce power consumption were used, enabling a 16% improvement in power usage.

To confirm the performance of the constructed multi-core transmission line to beyond 100 Tbit/s transmission, 16QAM-based 116-wavelength signals were prepared and the output signal quality over 316 km transmission was examined.

Additionally, Fan-In/Fan-Out devices developed by NTT and Furukawa were used to input/output signals to and from each core of the multi-core fibre. Pluggable optical connectors with existing MU-type or SC-type interfaces from CIT and NTT were used to connect the input/output end of the multi-core transmission lines and Fan-In/Fan-Out devices.

The work was partially based on work commissioned by the National Institute of Information and Communications Technology (NICT), and the companies stated that they aim to introduce the standard diameter multi-core fibre by the early 2020s. The achievement was reported in early August as a post deadline paper at the Opto Electronics and Communications Conference (OECC 2017) in Singapore.

Kaiam expands UK manufacturing capacity via acquisition of facilities from CP

Kaiam, a privately-held developer of hybrid photonic integrated circuit (PIC) technology, announced the completion of its acquisition of the manufacturing facilities of Compound Photonics (CP) in Newton Aycliffe, Durham in the UK as part of a transaction that also includes investment by CP into Kaiam to further develop the facility.

The Newton Aycliffe facility will enable Kaiam to significantly increase its manufacturing capacity for silica-on-silicon planar lightwave circuits (PLCs) and 40 and 100 Gbit/s transceivers, and adds both electronic and optoelectronic compound semiconductor devices to the product line. The acquisition also includes tooling and an experienced team that complements and expands Kaiam's existing Livingston, Scotland factory.

Kaiam noted that the new facility will enable it to produce InP photonic integrated circuits (PICs) that will form the basis for advanced transceivers in the future. The transaction continues Kaiam's strategy of achieving vertical integration, building on its acquisition of Gemfire's PLC fab in 2013.

The Newton Aycliffe facility encompasses 300,000 sq feet and includes a fully operational wafer fab with 100,000 sq feet. of cleanroom space for processing, packaging, and testing of III-V devices. The factory is currently shipping GaAs devices and circuits, with the capability to produce InP optoelectronics. Kaiam noted that the facility was originally built as a silicon fab for DRAMs before being converted to III-V materials and currently has 3 and 6 inch lines.
Kaiam announced in March that it planned to acquire the manufacturing facilities of Compound Photonics (CP) in Newton Aycliffe. Kaiam acquired Gemfire, its strategic PLC supplier, in 2013 and currently operates an 8 inch silica-on-silicon line for the fabrication of integrated optical components in Gemfire's Livingston facility in Scotland. It also operates 40 and 100 Gbit/s optical packaging lines at the facility, and noted at the time that these were nearing capacity.

Compound Photonics (CP) is a privately held photonics company with a focus on liquid crystal on silicon display devices and laser technologies for a range of applications in the projection and near to eye display markets.


Commenting on the acquisition, Bardia Pezeshki, Kaiam CEO, said, "… future transceivers that run at higher speed and use complex modulation formats will require integrated photonic elements that are highly differentiated and will not be readily available in the market… this new facility will give Kaiam this essential PIC capability, positioning it to meet customers' needs for improving speed, cost, power, density and manufacturing scale".

LightCounting reports record optical networking market in '16

Market research firm LightCounting finds in its latest Optical Communications Market Forecast report that while demand for optical networking equipment, modules and components attained record levels in 2016, the market was weak in the first quarter of 2017.

LightCounting reports that Huawei led the market in terms of growth in 2016, but significantly reduced purchases of optics in the first quarter of 2017 and forecasts that this weakness is likely to continue in the current quarter. However, the research firm believes that this a temporary slowdown in the optical market.

Looking at data for overall capex of the Top 15 service providers globally, LightCounting notes a sharp decline in Asia in 2016 due to lower spending by the big three Chinese operators, while spending in the U.S. and Europe remained stable versus 2015. Even so, 2016 was a record year for optical communications equipment revenue, which typically accounts for around 10% of service provider capex.

China

China Mobile was the largest consumer of optics in 2016 and added 30 million FTTH subscribers and deployed more than 50,000 ports of 100 Gbit/s DWDM optics into its core network. In addition, upgrades of China Mobile's metro and metro access networks drove demand for 10 Gbit/s optical components and modules. LightCounting notes that while some upgrade projects were completed in 2016, many are ongoing.

The research firm also cites a presentation by China Mobile at OFC 2017, in which the operator said that traffic growth rates in its network rose from 46% in 2013-14 to 88% in 2015-16, compared with a growth global rate of around 30%. Therefore, China Mobile, along with China Telecom and China Unicom, are expected to continue their high levels of spending to address above average traffic growth. LightCounting states that the capex-to-revenue ratio for Chinese service providers is around 25%, compared to 15% for all other operators.

LightCounting estimates that deployments of 100 Gbit/s DWDM ports in China in 2016 translate to a 70% increase in network bandwidth, and predicts that Chinese service providers will increase bandwidth in DWDM networks by a further 40% in 2017. However, it believes that deployments will increase in 2018 to keep pace with traffic growth.

Cloud DCI

Regarding DWDM deployments in the cloud/data centre interconnect (DCI) and enterprise segments, LightCounting observes that while this is a relatively small market in terms of total bandwidth, it is growing much faster that the service provider segment. As a result, bandwidth demand from cloud companies connecting data centres is expected to be very high in 2017.

LightCounting notes that Amazon and Facebook report that traffic inside their data centres is increasing by 100% annually. While growth in traffic between data centres is expected to be slower, based on the rate of construction of new data centres the research firm predicts 100% bandwidth growth for DCI traffic 2017. This increase in DWDM bandwidth demand for cloud DCI is expected to compensate for lower demand in China.

Lightwave Logic Demos Modulation with P2IC enabling 25G

Colorado-based Lightwave Logic, a company developing photonic devices and non-linear optical polymer materials for optical data communications and telecommunications applications, announced it has achieved bandwidth suitable for 25 Gbit/s data rates in an all-organic polymer ridge waveguide intensity modulator prototype.

The company noted that the 25 Gbit/s capability demonstration marks a significant improvement over its initial 10 Gbit/s device modulator that it reported last December.

Lightwave Logic explained that a modulator converts electronic information into light pulses that can traverse optical cables used in data centres, for data communications and high performance computing applications. To achieve a 100 Gbit/s data rate, modulators are typically configured in groups of four, each supporting 25 Gbit/s data rate.

Lightwave Logic's polymer photonics integrated circuit (P2IC) is similar to an electronic integrated circuit, but incorporates two or more optical functions on a single substrate platform. P2IC devices are expected to allow increased component density, with numerous photonic functions enabled using electro-optic polymer materials. This can provide scalable photonic devices offering lower cost together with higher performance.

In December 2016, Lightwave Logic announced it had achieved high-speed modulation utilising its first all-organic polymer ridge waveguide intensity modulator prototype. The company stated that the prototype could enable bandwidth sufficient to support data rates of around 10 Gbit/s, and that it anticipated increasing this performance to 25 Gbit/s.

Recently, Lightwave Logic announced that Dr. Michael Lebby, who established Intel's photonics division, would assume the role of CEO, effective May 1, 2017, succeeding Tom Zelibor who will remain as board chairman. It also recently elected Dr. Fred Leonberger, formerly with JDS Uniphase, to its board.


Commenting on the announcement, Lightwave Logic CEO Tom Zelibor said, "Enabled by the P2IC polymer system, this prototype device is suitable for data rates at 25 Gbit/s, and I believe it can be scaled to operate up to 50 Gbit/s… which would be the key to… addressing the next large market, 400 Gbit/s nodes".

Nokia announced it has been selected to deploy a 100 Gbit/s network in the Chogoku area of Japan for Energia Communications (EneCom), the main utility and telecommunications company in the area.

With the deployment of an advanced optical transport system integrated with 100/200 Gbit/s coherent technology, the Nokia solution is designed to transform EneCom's transport network and enable more flexible and reliable services. The network is being deployed in the Chugoku area on Japan's main island, Honshu, encompassing the major cities of Okayama and Hiroshima.

Under the agreement, Nokia will deploy its 1830 Photonic Service Switch (PSS) to provide integrated, ultra-wideband wavelength routing and switching to optimise EneCom's networks to support fluctuating traffic demand. The solution is based on Nokia's advanced super coherent digital signal processor, the Photonic Service Engine 2 (PSE-2), and also features GMPLS and CDC-F ROADM functionality.

The upgrade is designed to enable EneCom to meet increasing traffic demands, as well as offer protection during natural disasters. The network features real-time optical fibre supervision, which provides monitoring and allows fibre breaks to be located, for improved operations and maintenance efficiency and increased reliability.

Previously, in early 2016 Nokia and EneCom announced the commercial deployment of G.fast technology in Japan to allow the ICT service provider to utilise existing copper networks to deliver up to 1 Gbit/s broadband access to residential subscribers. It was noted the deployment followed a G.fast technology trial conducted in 2015. EneCom was to initially deploy G.fast in the Chugokua region of Japan starting June 2016.


EneCom specifically selected Nokia's 7367 Intelligent Service Access Manager (ISAM) SX-16 to enable G.fast connectivity for multiple, and the 7368 ISAM CPE F-010G-P for home devices. It was also to install the 5520 Access Management System. EneCom had also previously announced trials of Nokia's TWDM-PON technology.
