IBM Implements 100G Optical Transceiver in Sub-100nm CMOS

IBM announced another significant advancement with is CMOS integrated nano-photonics technology. The company said its researchers for the first time have tested a fully integrated wavelength multiplexed silicon photonics chip, which will soon enable manufacturing of 100 Gbps optical transceivers. The design implements multiple optical components side-by-side with electrical circuits on a single silicon chip using sub-100nm CMOS technology.

“Making silicon photonics technology ready for widespread commercial use will help the semiconductor industry keep pace with ever-growing demands in computing power driven by Big Data and cloud services,” said Arvind Krishna, senior vice president and director of IBM Research. “Just as fiber optics revolutionized the telecommunications industry by speeding up the flow of data -- bringing enormous benefits to consumers -- we’re excited about the potential of replacing electric signals with pulses of light. This technology is designed to make future computing systems faster and more energy efficient, while enabling customers to capture insights from Big Data in real time.”

IBM's new 100G transceiver has a range of up to 2 kilometers and uses four laser at different wavelenghts, each operating as an independent 25 Gbps optical channel. Within a full transceiver design, these four channels can be wavelength multiplexed on-chip to provide 100 Gbps aggregate bandwidth over a duplex single-mode fiber, thus minimizing the cost of the installed fiber plant within the data center.

100G and Beyond - @Huawei Comments at #OFC2015

What changes will we see as network transport evolves to 100G and beyond? Peter Ashwood-Smith, Technical VP of Optical Product Line at Huawei, breaks it down into a discussion of the control layer and the physical interface.  He sees 100G as the "workhorse" of optical transport for the next 3-5 years. We'll see improvements in density and the adoption on pluggable formats in 100G interfaces. Another factor for 100G is silicon photonics.

OpenOptics MSA Consortium Releases WDM Spec for DCI

The OpenOptics MSA Consortium has published the first foundational Wavelength Division Multiplexing (WDM) specification for an interoperable 100G WDM standard for 2 kilometer reach, addressing data center interconnect (DCI) requirements.

RANOVUS said this new WDM specification brings together 1550nm WDM laser and silicon photonics for QSFP and optical engine based solutions, enabling lowest-cost, highest density, and highest bandwidth with single mode fiber pair connectivity, to enable data centers to use up to 32 or more channels per fiber strand.

“Our OpenOptics MSA collaboration with industry leaders has resulted in the definition of a foundational WDM specification for data center network connectivity, and having terabit scalability on a single mode fiber pair infrastructure,” said Saeid Aramideh, chief marketing and sales officer for RANOVUS.  “The availability of this specification is a major milestone for our industry which we believe will not only accelerate the adoption of silicon-photonics based WDM solutions for the data center market, but also allow for a scalable terabit infrastructure for next generation datacenter architectures.”
 
“Previously, there was no standard for anything beyond 100Gbs,” said Gilad Shainer, vice president of marketing at Mellanox Technologies. “Now, the industry will have an architecture standard that scales to a terabit and beyond on existing fiber, substantially reduces the cost of hyperscale data center networks.”

http://www.ranovus.com

Earlier this month, the OpenOptics Multi-Source Agreement group said it plans to contribute its developed wavelength specifications to the Open Compute Project (OCP). The new specification enables data to be streamed at terabits per second over a single fiber.

The founders and supporters for the OpenOptics MSA for Highly Scalable Interconnect Solutions include Mellanox Technologies, RANOVUS, Ciena, Oracle, Vertilas, and Ghiasi Quantum. The MSA combines 1550 nm WDM laser and silicon photonics for optical networking solutions enabling the lowest cost, highest density, and highest bandwidth single mode fiber (SMF) connectivity, significantly improving terabit-scale data center infrastructure ROI.

Canadian Researchers Develop Photon Pair Source

An international team of researchers led by professor Roberto Morandotti of INRS-EMT in Canada announced a new method to achieve a different type of photon pair source that fits into a computer chip. To generate the cross-polarized photons, Caspani and colleagues used two different laser beams at different wavelengths —one vertically polarized and another horizontally polarized.

The researchers said their innovation could form the core of the next-generation of quantum optical communication and computing technology.

The research will be presented at The Optical Society's (OSA) 98th Annual Meeting, Frontiers in Optics, being held Oct. 19-23 in Tucson, Arizona, USA.

“While several efforts have been devoted to develop on-chip sources of polarization-entangled photons, the process typically used to generate these photons only allows the generation of photons with the same polarization as the laser beam used to pump the device — either both horizontal or vertical — after which entanglement can be achieved by accurately mixing these states. Now, we have found a way to directly generate cross-polarized photon pairs,” says Lucia Caspani, a postdoctoral fellow at INRS-EMT and co-author of the Frontiers in Optics paper.

Compass-EOS Introduces SDN Forwarding Plane

Compass-EOS introduces its SDN Forwarding Plane, a new networking element that aims to replace expensive and complex routers used in service provider networks.

The Compass-EOS said key attributes of its SDN Forwarding Plane include:

  • A scalable, high-capacity, low-latency, programmable secure packet forwarding  platform
  • Support for SDN/NFV-based open-standard protocol
  • The Compass-EOS AnyFLOW Architecture, a unique, hybrid SDN architecture that combines network topology resolution and packet forwarding on multiple levels
  • Compass-EOS icPhotonics technology for scalability and low-latency

Compass-EOS has also joined the Open Daylight open-source SDN community and is planning to contribute code and expertise for WAN-centric SDN applications.

Compass-EOS also disclosed a new chip on its product roadmap that will enable its routers and SDN Forwarding Plane solution to grow from its current total capacity of 1.34 Terabits/sec to higher than 10 Terabits/sec.

“With the world’s first commercial technology combining high-capacity inter-chip optical interconnect and digital processing in the same silicon chip, Compass-EOS’ icPhotonics™ technology gives us the unique opportunity to completely transform the  information and communications technology industry as we know it, unleashing a new generation of devices and innovation that disrupts the current network equipment paradigm," said Matt Bross, Compass-EOS Chairman and CEO.

“This gives birth to a new network element – an SDN Forwarding Plane that takes its instructions from processes in the cloud and defines in detail what each flow in the plane is doing in a packet-by-packet basis,” Bross continued. “This type of technology capability simply doesn’t exist in legacy platforms. The SDN Forwarding Plane is more powerful yet less complex and power hungry. More importantly, it can also incrementally scale through the simple addition of more devices, just like servers are used to scale data centers today.”

Intel Unveils Knights Landing Processor and Omni Scale I/O Fabric

Intel announced microarchitecture and memory details of its next-generation Intel Xeon Phi processor (code-named Knights Landing) and an end-to-end interconnect fabric optimized for fast data transfers, both aimed at powering High-Performance Computing (HPC) systems.

Knights Landing, which is expected to debut in the second half of 2015, will include up to16GB high-bandwidth, on-package memory at launch – designed in partnership with Micron – to deliver five times better bandwidth compared to DDR4 memory, five times better energy efficiency and three times more density than current GDDR-based memory. Knights Landing will be available in a PCIe-based card option, or mounted directly on the motherboard socket to remove the bandwidth bottlenecks of data transfer over PCIe, common in GPU and accelerator solutions.

Powered by more than 60 HPC-enhanced Silvermont architecture-based cores, Knights Landing is expected to deliver more than 3 TFLOPS of double-precision performance and three times the single-threaded performance compared with the current generation.

Intel's new Omni Scale fabric, which is built upon a combination of enhanced acquired IP from Cray and QLogic along with tis own in-house innovations, addresses the I/O requirements of the HPC sector.  Intel Omni Scale Fabric is an end-to-end I/O solution encompassing adapters, edge switches, director switch systems, cables and management software. Intel intends to replace traditional electrical transceivers in the director switches with silicon photonics, enabling increased port density, simplified cabling and reduced costs. Intel Silicon Photonics-based cabling and transceiver solutions may also be used with Intel Omni Scale-based processors, adapter cards and edge switches.

Intel noted continued market gains in powering the HPC sector.  The company said its current generation of Xeon processors and Xeon Phi coprocessors powers the top-rated system in the world – the 35 PFLOPS "Milky Way 2" in China, and its designs account for 85 percent of all supercomputers on the 43rd edition of the TOP500 list.

Intel: From Silicon to Platforms

"If it computes, it does it best with Intel" -- this statement underscores Intel's mission, said company CEO Brian Krzanich, speaking at the Intel Investor's Day conference in Santa Clara, California. Intel is dedicated to "a new pragmatism" that will make the company much more market driven, said Krzanich, with a the goal of capturing significant inroads in the data center and mobile computing. Among the changes to the way the company does business is that decision to open its foundry to any company able to utilize its silicon and the decision to create platforms for the data center, not just server and switching silicon.

Some highlights taken from half-dozen executive presentations (now available on the company's website).

Data Center

  • Intel sees a 15% CAGR for data center products through 2016.
  • Intel's data center business spans Enterprise, Telco, HPC, Work stations and Cloud.  The company will move from delivering just silicon to complete solutions for each of these segments.
  • Intel believes the Telco market will transition to common server platforms for many workloads, including signal processing at the edge, control plane processing, application processing and data plane processing.  This is a major transition and will help offset Service Provider CAPEX/OPEX.
  • AT&T's Supplier Domain 2.0 program is an example of the move to open software and hardware solutions.
  • The move to SDN and NFV will also drive the move to Intel architectures. Over 15 major telcos worldwide are in the process of qualifying new systems based on Intel systems.
  • Proprietary network appliances are being virtualized and migrated on open servers based on Intel.
  • Intel currently estimates that it has about 5% of the overall network equipment compute market, compared with 94% of the enterprise server compute market.  The company believes the performance gains of its Xeon processors will enable it to challenge the ASIC-based systems currently used in many networking platforms.
  • Intel estimates that every 400 new Connected Devices sold leads to the sale of 1 new server. Every new 20 Digital Signs leads to 1 new server.
  • Internet of Things will drive faster change: a metro area smart traffic deployment will require 30K cameras, 10K gates, 2.5K servers, 650 network switches, 250 storage systems -- based on a real project in China.
  • 6 of 7 top data center customers bought “higher bin” CPUs vs. prior year.
  • Intel delivers unique server processors for eBay (liquid cooled), Facebook (cold storage server), and Nuance (optimized for voice processing)
  • Intel is delivering its new open rack-scale architecture to the Open Compute project and a similar "Scorpion" initiative in China.
  • In terms of connecting systems in a rack, copper will be challenged >25Gbps.
  • Current optical interconnect products are challenged >100m, >25Gbps.
  • Intel's Silicon Photonics has demonstrated 800m reach at 25Gbps.  This will enter production in Q1 2014.
  • Intel currently holds No.1 market share in enterprise SSDs.  Upcoming technologies will redefine the boundary between memory and storage.
Mobility and PC

  • About 1.5 billion smartphones and tablets will ship in 2014 (overall market).
  • Intel believes the PC market is stabilizing, although still declining at single digit rates.
  • In 2014 aims for 40 million tablets sold -- a 4X gain over expected 2013 Intel tablet shipments.
  • Intel seeks to change the "PC experience" by pushing 2-in-1 convertible and detachable PC/Tablet devices, with prices under $300.
  • Look for Intel-powered tablets on the market for under $100.
  • The first LTE chipset (XMM7160) is shipping and the LTE-Advanced chipset (XMM7260) will be out next year.
  • The forthcoming Broxton chip (next gen Atom) will offer a unique design that will allow it to be quickly adapted for specialized devices. Target date is mid-2015.
  • A new SoFIA chipset will provide integrated global LTE multi-comm connectivity with Intel Atom inside.  Initially it will be built in an external foundry for market pragmatics, but brought back inside with a move to 14nm.
  • Intel believes "perceptual computing" will be a big trend - using voice and motion sensors to make computing a 3D experience.
Manufacturing
  • Intel's 10nm process technology will be ready in 2015.
  • Opening the foundry means focusing on a much wider range of customers.
  • Initial foundry customers include achronix, Altera, Microsemi, Netronome and Tabula.

NTT Com Selects Compass-EOS' Silicon-Photonic Routers

NTT Communications has selected Compass-EOS' new r10004 core-grade modular routers for use in its high-capacity transpacific network. The Compass-EOS routers are the world’s first direct silicon-to-photonics-based routers.

“We chose Compass-EOS routers to be used at the termination points of our transpacific high-capacity network, providing a vital link between North America and APAC,” said Dorian Kim, Vice President of IP Engineering at NTT Communications. “The high bandwidth and low power consumption, together with the modularity of the Compass-EOS router family fit well with our future vision and plans.”

“We are thrilled to have NTT Communications among the first production users of our r10004 routers,” said Gadi Bahat, CEO of Compass-EOS. “We look forward to working with them on their implementation in building simple, innovative networks that deliver better services to their customers.”

http://compass-eos.com/

Last month, Compass-EOS unveiled its radical silicon-to-photonics router that essentially leverages an on-chip optical mesh and electronics to route high-densities of 100GbE and 10GbE.

The company's silicon-to-photonics implementation, which it calls icPhotonics, simplifies router design by bringing the entire backplane on-chip, thereby enabling petabit-class scalability, significantly smaller footprint and power consumption, and easier implementation of software-defined networking capabilities.  The on–chip optical integration ensures QoS routing at high utilization rates and congestion-free multicast packet handling. Compass-EOS said it is also able to ensure maximum router protection from DDoS attacks at maximum capacity.

The company's first product, r10004, is a carrier-grade, modular platform offering 800 Gbps Capacity in a 6U enclosure.  It offers 2 x 100G ports or 20 x 10G ports with full Layer 3 routing functionality for core, peering or aggregation deployments.

OneChip Photonics Intros 100G PIC in Indium Phosphide

OneChip Photonics introduced a Photonic Integrated Circuit (PIC)-based 100 Gbps device that monolithically integrates all of the optical functions required for an optical transceiver into a single Indium Phosphide (InP)-based chip. All of the active components (Distributed Feedback “DFB” laser, Electro-Absorption Modulator “EAM,” and Waveguide Photodetector “WPD”) and passive components (Wavelength Division Multiplexing “WDM” combiner, splitter and Spot-Size Converter “SSC”) of the chip are, uniquely, integrated in one epitaxial growth step – without re-growth or post-growth modification of the epitaxial material.

The company said its Multi-Guide Vertical Integration (MGVI)-based PICs will enable transceiver manufacturers to produce high-speed, low-power and small-size modules for Data Center Interconnect (DCI) applications.

The MGVI platform in Indium Phosphide is based on the same process that inherently produces the best and fastest Heterojunction Bipolar Transistors (HBTs) used in Radio Frequency Integrated Circuits (RFICs). As such, the company also will be able to integrate electronics, such as Transimpedance Amplifiers (TIAs) and modulator drivers, within a commercially available and volume-scalable process. The silicon photonics dream of leveraging high-volume electronic chip production, while combining photonics and electronics onto the same substrate, is ironically best realized in Indium Phosphide.
