Lightmatter is developing a photonic processor

Lightmatter, a start-up based in Boston, will unveil plans for an artificial intelligence (AI) photonic processor.

Lightmatter said its general-purpose AI inference accelerator will use light to compute and transport data. The 3D-stacked chip package contains over a billion FinFET transistors, tens of thousands of photonic arithmetic units, and hundreds of record-setting data converters. Lightmatter’s photonic processor runs standard machine learning frameworks including PyTorch and TensorFlow, enabling state-of-the-art AI algorithms.

“The Department of Energy estimates that by 2030, computing and communications technology will consume more than 8 percent of the world’s power. Transistors, the workhorse of traditional processors, aren’t improving; they’re simply too hot. Building larger and larger datacenters is a dead end path along the road of computational progress,” said Nicholas Harris, PhD, founder and CEO at Lightmatter. “We need a new computing paradigm. Lightmatter’s optical processors are dramatically faster and more energy efficient than traditional processors. We’re simultaneously enabling the growth of computing and reducing its impact on our planet.”

On August 18th, Lightmatter’s VP of Engineering, Carl Ramey, will present their photonic processor architecture at HotChips32.

Continuous-Wave Wavelength Division Multiplexing MSA gets underway

A new Continuous-Wave Wavelength Division Multiplexing Multi-Source Agreement (CW-WDM MSA) consortium has been established to define and promote specifications for multi-wavelength advanced integrated optics.

The CW-WDM MSA said it will solely focus on specifying the laser source instead of the full communications link, and is not targeted at any specific application. Such an approach allows developers to fully optimize optics to their customers’ requirements without interoperability constraints while simultaneously creating a large business opportunity for laser source suppliers.

Currently, IEEE and MSA standards specify four WDM interfaces. Emerging advanced integrated optics applications, such as silicon photonics (SiPh) based high-density co-packaged optics, optical computing, and AI, are expected to move to 8, 16, and 32 wavelengths. Standardizing higher wavelength counts is a crucial part of an emerging ecosystem which is enabling a leap in efficiency, cost, and bandwidth scaling compared to current technology. Increasing the number of wavelengths, while staying in the O-band and aligning with ITU and IEEE standards, allows developers and suppliers to leverage their strategic investments in the current generation of optical products to accelerate time to market of next generation products.

Promoter Members of the CW-WDM MSA are Arista Networks, Ayar Labs, CST Global, imec, Intel, Lumentum, Luminous Computing, MACOM, Quintessent, Sumitomo Electric, and II-VI.

In addition, several Observer Members have signed on to be briefed on the development of the standard to enable early technology development based on the new specifications. Observer Members are AMF, Axalume, Broadcom, Coherent Solutions, Furukawa Electric, GlobalFoundries, Keysight Technologies, NeoPhotonics, NVIDIA, Samtec, Scintil Photonics, and Tektronix.

“Laser sources have been the critical building block of fiber optic communications, and standardizing their specifications has been key to the success of telecom and datacom optics,” said Chris Cole, Chair of the CW-WDM MSA. “ITU-T established complete baselines for DWDM and CWDM grids. The IEEE then specified subsets of these grids for high volume data center applications, starting with 40G and 100G Ethernet optics. The CW-WDM MSA will similarly leverage ITU-T and IEEE standards to specify 8, 16 and 32 wavelength grids in O-band for emerging advanced datacom and computing optics. With the definition of multiple grid sets, the MSA will enable developers to choose what is optimum for their application, while allowing laser suppliers to only have to invest in one technology platform.”

“We support and encourage consortiums like the CW-WDM MSA Group in order to accelerate important technical innovations,” said Christopher Berner, Head of Compute at OpenAI. “OpenAI must be on the cutting edge of AI capabilities and low latency, high bandwidth optical interconnect is a central piece of our compute strategy to achieve our mission of delivering artificial intelligence technology that benefits all of humanity.”

Fujitsu develops Multi-Domain Optical Network Services within ONAP

Fujitsu Network Communications announced the first implementation of Multi-Domain Optical Network Services (MDONS) within the Open Networking Automation Platform (ONAP) Frankfurt Release.

Fujitsu’s open-source contribution, which was developed in collaboration with The Linux Foundation, Orange and other global service providers, extends ONAP orchestration into the optical space, allowing network operators to design, orchestrate and automate Optical Transport Network services across service provider networks.

The MDONS blueprint leverages Open ROADM, ONF Transport API (TAPI), and MEF standards to enable multi-vendor and multiple domain operation. Open APIs to SDN Controllers deliver multi-vendor service activation and provisioning. The newly added ONAP optical services capabilities will allow for the development of enhanced service offerings and applications customized to the needs of service providers, further driving network automation at the optical layer.


“In the past, service providers relied on a complex negotiation of manual processes for even the most basic inter-connections between network domains,” said Rod Naphan, head of the technology business unit at Fujitsu Network Communications, Inc. “By leveraging ONAP and open APIs, our customers can now automatically orchestrate and provision optical services across multiple domains, resulting in faster service turn up and reduced operating expenses.”

“Network automation is a strong business requirement. We fundamentally believe open-source collaboration is the best way to respond to this complex prerequisite,” said Olivier Augizeau, network automation project manager at Orange. “The latest Frankfurt release of the ONAP platform paves the way to improve the footprint of optical connectivity services with cross carrier scenarios.”

“We are encouraged by the success of the ONAP members working together to advance the platform with new use cases, enhancements, commercial deployments and adoptions in the latest release, Frankfurt,” said Arpit Joshipura, general manager, networking, Edge & IoT, at The Linux Foundation. “As a valued LFN member vendor with extensive optical expertise, Fujitsu’s participation in initiating the MDONS blueprint is an important part of the overall team efforts to enhance the ONAP framework.”

The first implementation of MDONS is part of broader ONAP initiatives to advance automation in the 5G Era, enabling multi-layer operations and end-to-end lifecycle management across wireline and wireless networks. Fujitsu is committed to working with our open source partners in leading this shift towards open networking.

Australian researchers achieve 44.2 Tbps from a single light source.

Researchers from Monash, Swinburne and RMIT universities in Australia have tested a single light source delivering 44.2 Tbps. The research, which is published in the journal Nature Communications, tested a device that replaces 80 lasers with one single piece of equipment known as a micro-comb.

The ultra-high data transmission occurred over 75 km of standard optical fibre using the single integrated chip source over the C-band at 1550 nm with a spectral efficiency of 10.4 bits s−1 Hz−1. Micro-comb spacing of 48.9 GHz enabled the use of 64 QAM - quadrature amplitude modulated.

Professor Moss, Director of the Optical Sciences Centre at Swinburne, says: “In the 10 years since I co-invented micro-comb chips, they have become an enormously important field of research. “It is truly exciting to see their capability in ultra-high bandwidth fibre optic telecommunications coming to fruition. This work represents a world-record for bandwidth down a single optical fibre from a single chip source, and represents an enormous breakthrough for part of the network which does the heaviest lifting. Micro-combs offer enormous promise for us to meet the world’s insatiable demand for bandwidth.”

Nokia debuts WaveFabric Elements: photonic chips, devices, subsystems

Nokia unveiled its WaveFabric Elements portfolio of photonic chips, devices and subsystems, including its fifth generation coherent digital signal processor family, the Photonic Service Engine V (PSE-V).
The company said its WaveFabric Elements address the demanding power, performance, and cost-per-bit requirements of 400G networking across data center, metro, core and subsea applications.

Nokia’s WaveFabric Elements portfolio combines digital signal processing (DSP) and optics technologies focused on emerging end-to-end 400G applications. The new, fifth generation coherent DSP family consists of multiple designs optimized for different optical networking applications, form factors, and platforms. These include:

  • PSE-Vs (super coherent), which can run up to 90 Gbaud and employ the second generation of Nokia Bell Labs-pioneered probabilistic constellation shaping (PCS). PSE-Vs are capable of transporting up to 800G, while providing 60% greater reach, 40% lower power per bit, and 15% greater spectral efficiency than previous DSP generations. 
  • PSE-Vc (compact), which enables programmable capacity from 100G to 400G with metro to long haul capability. Its extremely low power enables integration into a variety of pluggable transceiver modules.

The new DSPs are complemented by the CSTAR portfolio of coherent optical modules from its recent acquisition of Elenion Technologies. CSTAR leverages state-of-the-art silicon photonics and packaging technology, and addresses applications, including intra-data center, metro DCI and long-reach optical transport. In addition to pairing them with the new PSE-V DSPs within Nokia platforms, the company will sell them independently to industry partners for integration into pluggable transceiver modules available to the broader market.

The CSTAR family of optical engines is currently shipping to customers. PSE-V-based platforms and pluggables will be available beginning in Q4 2020.

Sam Bucci, Head of Optical Networks at Nokia, said: "Networks are truly at an inflection point, and 400G will be a catalyst for a significant transformation. With our WaveFabric Elements portfolio, Nokia is committed to supplying the 400G optical ecosystem with components, subsystems and design services, as well as continuing to build the highest performing optical transport solutions for the 400G era and beyond."

NeoPhotonics intros 64 GBaud L-band coherent optical components

NeoPhotonics introduced an L-Band suite of coherent optical components, including its 64 GBaud L-Band High Bandwidth Coherent Driver Modulator (HB-CDM), 64 GBaud L-Band Intradyne Coherent Receiver (ICR) and ultra-narrow linewidth L-Band tunable laser Micro-ITLA. NeoPhotonics already supplies standard C-Band coherent components.

NeoPhotonics notes that the L-Band uses wavelengths centered around 1590 nm and is primarily used to complement the C-Band (1550 nm) to increase data capacity, especially in long-haul networks. By adding channels in the L-Band, operators can double the capacity of an optical fiber. NeoPhotonics 64 Gbaud coherent components and tunable lasers enable single channel 600G data transmission over short haul data center interconnect (DCI) links using 64 QAM. These components also support 400G over metro distances of 400-600 km using 64 GBaud and 16 QAM or 200G over long-haul distances of greater than 1000 km using 64 GBaud and QPSK.

The NeoPhotonics L-Band External Cavity (ECL) micro-ITLA incorporates the same laser architecture as its C-Band laser for a pure optical signal with an ultra-narrow linewidth and very low phase noise. In coherent systems, any error in the phase of the signal and reference lasers, due to the laser’s linewidth, can cause data errors, thereby making narrow linewidth critical in systems using higher order modulation.

The NeoPhotonics 64 Gbaud L-Band HB-CDM co-packages an Indium Phosphide based Mach-Zehnder (MZ) quadrature modulator chip with a linear, quad-channel, differential 64 GBaud driver. Both the C-Band and L-Band versions of the HB-CDM are designed to be compliant to the Optical Internetworking Forum (OIF) Implementation Agreement OIF-HB-CDM-01.0 “High Bandwidth Coherent Driver Modulator”.

NeoPhotonics 64 Gbaud L-Band Micro-ICR incorporates an integrated comixer chip and four balanced photodiodes with four differential linear amplifiers to provide four output channels at 64 GBaud. The form factor of the High Bandwidth Coherent Receiver is designed to be compliant with the OIF Implementation Agreement for Micro Integrated Intradyne Coherent Receivers; IA # OIF-DPC-MRX-02.0.

For applications that require more capacity than provided by the standard C-Band, but do not require the full L-Band, each of these components is available in a “C++” version, which supports tuning across the full “Super C-band” covering 6.0 THz of spectrum or up to 50 percent more than standard systems. These C++ components can support 80 channels at 75 GHz channel spacing, which effectively increases the capacity of an optical fiber by as much as 50 percent over standard C-Band only systems at comparable distances.

"We are pleased to add L-Band versions to our existing suite of coherent components, thus providing customers with a complete solution to their fiber capacity requirements, whether C-Band, C++ Band or L-Band," said Tim Jenks, Chairman and CEO of NeoPhotonics. "Our ultra-pure tunable laser design and our high performance coherent modulator and receiver designs are very flexible and excel in different spectral regimes to provide the highest speed over distance performance," concluded Mr. Jenks.

Nokia hits record single carrier bit rate of 1.52 Tbps over 80 km

Researchers at Nokia Bell Labs achieved a world record for the highest single carrier bit rate at 1.52 Terabits per second (Tbps) over 80 km of standard single mode fiber.

Marcus Weldon, Nokia CTO and President of Nokia Bell Labs, said: “It has been fifty years since the inventions of the low-loss fiber and the associated optics. From the original 45 Megabit-per-second systems to more than 1 Terabit-per-second systems of today – a more than 20,000-fold increase in 40 years – to create the fundamental underpinning of the internet and the digital societies as we know it. The role of Nokia Bell Labs has always been to push the envelope and redefine the limits of what’s possible. Our latest world records in optical research are yet another proof point that we are inventing even faster and more robust networks that will underpin the next industrial revolution.”

The Nokia Bell Labs optical research team, which was led by Fred Buchali, employed a new 128 Gigasample/second converter enabling the generation of signals at 128 Gbaud symbol rate and information rates of the individual symbols beyond 6.0 bits/symbol/polarization.  This accomplishment breaks the team’s own record of 1.3 Tbit/s set in September 2019 while supporting Nokia’s record-breaking field trial with Etisalat.

Several of these achievements were presented as part of Nokia Bell Labs’ post deadline research papers at the Optical Fiber Communications Conference & Exhibition (OFC) in San Diego.

Additionally, Nokia Bell Labs researcher Di Che was awarded the OFC Tingye Li Innovation Prize.

Recently, Di Che and team also set a new data-rate world record for directly modulated lasers (DML) by transmitting a 400 Gbps signal up to 15 km.

Nokia Bell Labs also highlighted the following significant achievements in optical communications:

The first field trial using spatial-division-multiplexed (SDM) cable over a 2,000km span of 4-core coupled-core fiber was achieved by researchers Roland Ryf and the SDM team. The experiments clearly show that coupled-core fibers are technically viable, offer high transmission performance, while maintaining an industry standard 125-um cladding diameter.
A research team led by Rene-Jean Essiambre, Roland Ryf and Murali Kodialam introduced a novel new set of modulation formats that provide improved linear and nonlinear transmission performance at submarine distances of 10,000 km. The proposed transmission formats are generated by a neuronal network and can significantly outperform traditional formats (QPSK) used in today’s submarine systems.
Researcher Junho Cho and team experimentally demonstrated capacity gains of 23% for submarine cable systems that operate under electrical supply power constraints. The capacity gains were achieved by optimizing the gain shaping filters using neural networks.
The researchers that achieved the world record and research results are part of Nokia Bell Labs’ Smart Optical Fabric & Devices Research Lab, which designs and builds the future of optical communications systems, pushing the state-of-the-art in physics, materials science, math, software and optics to create new networks that adapt to changing conditions and go far beyond today’s limitations.

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.”

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.
