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.

NeoPhotonics intros 53 GBaud Linear Optical Components

NeoPhotonics announced its 53 GBaud Linear Optical Component family, which includes  PAM4 capable optical components for 100G and 400G cloud data center and other client applications, including drivers and EML lasers in transmitters plus PIN photodetectors and TIAs in receivers.

The 53 GBaud Linear Optical Component family from NeoPhotonics includes:

  • 53 GBaud Open Drain Driver (ODD) for linear operation of EML lasers. With a typical 90mW of power consumption per channel and small size, this high speed driver is well suited for space and power efficiency in small form factor pluggable modules.
  • 53 GBaud MZM drivers for Silicon Photonics modulators. This quad driver has a high 3.5Vppd output per channel and a typical 2.2W low power consumption for all four channels designed for small form factor pluggable modules.
  • 53 GBaud CWDM4 EML, which includes the option for integration with NeoPhotonics’ open drain driver. Over the operating temperature range from 20 to 70C, this EML is a preferred transmitter solution for PAM4 for intra-datacenter applications.
  • 53 GBaud PIN photodetectors. The side illumination structure of the PIN PD enables a simple coplanar assembly with mux/demux chip and TIA well suited for compact modules.
  • 53 GBaud Transimpedance Amplifier (TIA). With low noise and a typical power consumption of 60mA over a 3.3V rail, this TIA is well suited for receiver signal amplification for up to 10km transmission. 

“Our complete 53 GBaud Linear Optical Component family, with a typical bandwidth of 35 GHz for all these optical components, provides all needed optical components for single lambda 100Gbps transmitters and receivers, scalable to 400 Gbps transceivers with CWDM4 wavelengths.” said Tim Jenks, Chairman and CEO of NeoPhotonics.  “NeoPhotonics is pleased to now also support the cloud data centers and the industry with a solid and growing portfolio of cost effective optical components based on NeoPhotonics’ high speed platforms of GaAs driver, InP EML/PIN PD, and SiGe TIA,” continued Mr. Jenks.
