Inphi samples first 400ZR QSFP-DD transceiver

Inphi has begun sampling its COLORZ II 400ZR QSFP-DD pluggable coherent transceiver for cloud data center interconnects (DCIs) to major cloud operators and OEMs.

Inphi cites several industry firsts for its COLORZ II 400ZR QSFP-DD:

  • 400G single-chip, coherent Silicon Photonics Integrated Circuit (PIC) that includes all transmit and receive functions 
  • Innovative, low cost, passive alignment of fiber to the PIC that eliminates the complicated active alignment, using traditional optics
  • Low power, high performance, 7nm CMOS-based coherent DSP enabling 400ZR as well as extended reach 100/200/300/400G ZR+ modes
  • Integrated industry standard firmware management interface that enables full performance monitoring previously only available in DCI or transport systems directly from the optical module

 The 400ZR standard promises to lower the cost and power consumption of metro data center interconnect (DCI) by enabling switch and router companies to offer the same density for both coherent DWDM and client optics in the same chassis. This eliminates a layer of network connectivity that was previously required and supports high capacity DWDM connectivity directly from data center switches. 

Inphi said its COLORZ II represents a massive increase in switch rack capacity, while reducing the power consumption by as much as 80%. COLORZ II delivers up to 14.4T of capacity per rack unit (RU), compared to 2.4T or 3.6T per RU on competing solutions, representing a 4-6 x increase in throughput per chassis.

“Inphi continues to innovate as we provide an expanding suite of choices for cloud network operators and OEMs to gain the flexibility of high bandwidth DWDM connectivity in between data centers with the ability to rapidly scale their capacity,” said, Dr. Loi Nguyen, Sr VP, Optical Interconnect, Inphi. “By meeting the needs of cloud network companies that require extended link reaches, the 400ZR opens up new possibilities for DCIs to reduce total cost of ownership of cloud networks. As a fabless company we have proven our capability to quickly increase manufacturing and market share for our COLORZ 100G DWDM modules and are ready to meet our customers demand for COLORZ II.”

  • The interworking of the O-RAN open fronthaul interface was demonstrated on technology provided by FHK (Shenzen) and Viavi, which performs comprehensive tests based on the test specification by O-RAN with O-RU and UE emulator in a multiple-UE test environment.


The plugfest held in the NTT DOCOMO R&D Center presented multi-vendor interoperability between CU/O-DU and O-RU using the O-RAN Open Fronthaul interface and multi-vendor interoperability between eNB and gNB using the O-RAN X2 interface. The functionality has been successfully demonstrated by NTT DOCOMO, Fujitsu, NEC, and Nokia. NTT DOCOMO has already started 5G pre-commercial service with the presented products. An Open Test and Integration Center is planned to be established in Japan.

NORTH AMERICA

The plugfest and proof-of-concept conducted within an Open Test and Integration Center candidate in North America, 5G COSMOS, which consists of vendor and university labs in the NYC metro area, was hosted by AT&T and focused primarily on the validation of the O1 and A1 interfaces:

  • Physical Network Function (PNF) Plug and Play, a 3GPP-aligned O1 use case that provides a means for service providers to collaborate with equipment vendors to have PNFs discovered by Service Management Orchestration (SMO) via a PNF registration handler, was demonstrated by Nokia, CommScope and Ericsson. Remote SMO functions were also demonstrated with connections to labs in France and Germany.
  • Bulk Performance Management Data Collection was demonstrated by Ericsson and Nokia.
  • O1 interface functionality for Configuration, Performance, and Fault Management of multi-vendor equipment via a vendor-agnostic SMO was demonstrated by Altiostar, CommScope, and Samsung.
  • A1 interface functionality to optimize PCI/RSI for a large-scale RAN simulator using a closed loop automation framework was demonstrated by IBM, Tech Mahindra, Wipro and highstreet technologies.
  • Convergence of the Open Fronthaul Management Plane specification with O1 interface was demonstrated by Samsung.

“The O-RAN Alliance has been continuously expanding its influence in the industry since its inception. It is really amazing to see such a symbolic milestone achieved just 10 months since its release of the first specification in MWC Barcelona this year,” said Zhengmao Li, EVP of China Mobile. “The successful holding of the plugfest event globally with deep contribution from over 30 partners represents a consolidated step towards a full disaggregated O-RAN compliant 5G network.”

Dr. Hiroshi Nakamura, EVP and CTO, NTT DOCOMO commented, "We believe wide adoption of O-RAN compliant products will enable more agile, flexible and cost-effective network construction, and welcome the testing and integration efforts of O-RAN standards that are being carried out across the globe. NTT DOCOMO will continue to lead O-RAN Alliance activities and expand its 5G network, and will accelerate the co-creation of 5G services and markets with vertical industry partners."

Silicon-based optical parametric oscillator transforms wavelengths

Researchers from the National Institute of Standards and Technology (NIST), University of Maryland, and University of Colorado are developing a new optical parametric oscillator (OPO) light source that can produce output light at different wavelength than the input light. In addition to creating light at visible wavelengths, the OPO simultaneously generates near-infrared wavelengths that can be used for telecom applications.

The research is published in Optica, The Optical Society's (OSA) journal.

“Our power-efficient and flexible approach generates coherent laser light across a range of wavelengths wider than what is accessible from direct chip-integrated lasers,” said research team leader Kartik Srinivasan. “The on-chip creation of visible light can be used as part of highly functional compact devices such as chip-based atomic clocks or devices for portable biochemical analyses. Developing the OPO in a silicon photonics platform creates the potential for scalable manufacturing of these devices in commercial fabrication foundries, which could make this approach very cost-effective.”

“Nonlinear optical technologies are already used as integral components of lasers in the world’s best atomic clocks and many laboratory spectroscopy systems,” said Xiyuan Lu, first author of the paper and a NIST-University of Maryland postdoctoral scholar. “Being able to access different types of nonlinear optical functionality, including OPOs, within integrated photonics is important for transitioning technologies currently based in laboratories into platforms that are portable and can be deployed in the field.”

The Optical Society said the silicon-based device may enable variety of photonic applications across a range of wavelengths.

Some highlights:
The OPO based on a microring made from silicon nitride.
It is fed by approximately 1 milliwatt of infrared laser power — about the same amount of power found in a laser pointer.
As the light travels around the microring it increases in optical intensity until powerful enough to create a non-linear optical response in silicon nitride.
This enables frequency conversion, a nonlinear process that can be used to produce an output wavelength, or frequency, that is different from that of the light going into the system.
The device was used to convert 900-nanometer input light to 700-nanometer-wavelength (visible) and 1300-nanometer-wavelength (telecommunications) bands.
The OPO accomplished this using less than 2 percent of the pump laser power required by previously reported microresonator OPOs developed for generating widely separated output colors.

F5 to acquire Shape Security for $1 billion

F5 agreed to acquire Shape, a privately-held company supplying fraud and abuse prevention solutions, for approximately $1 billion in cash, subject to certain adjustments.

Shape provides protection from automated attacks, botnets, and targeted fraud. In particular, Shape defends against credential stuffing attacks, where cybercriminals use stolen passwords from third-party data breaches to take over other online accounts. Shape’s application protection platform evaluates the data flow from the user into the application and leverages highly sophisticated cloud-based analytics to discern good traffic from bad. With F5’s location in the data flow of traffic in over 80% of Fortune 500 application infrastructures, F5 provides the ideal insertion point for Shape’s security services. Together F5 and Shape will dramatically reduce the time and resources needed for organizations to deploy world-class online fraud and abuse protection.

F5 said the acquisition brings together its own expertise in protecting applications across multi-cloud environments with Shape’s fraud and abuse prevention capabilities to transform application security.

“We know from the companies we work with that applications are critical to running their business. To drive maximum business value and the best experiences for their customers, these apps need to perform flawlessly while protecting data security and user privacy. When a website or application experience is degraded by web fraud and abuse, the result is lost revenue, lost brand equity, and customers jumping ship to the competition,” said F5 President and CEO, François Locoh-Donou.

“With Shape, we will deliver end-to-end application protection, which means revenue generating, brand-anchoring applications are protected from the point at which they are created through to the point where consumers interact with them—from code to customer,” continued Locoh-Donou.

“Since Shape’s inception, we observed a consistent pattern in customer after customer: the use of F5 technology to deliver and enable their applications,” said Derek Smith, co-founder and CEO of Shape. “Now, we look forward to the opportunity to deeply integrate into F5’s platform for application delivery and security—F5 provides the optimum traffic flow insertion point for Shape’s industry-leading online fraud and abuse prevention solutions.”
