OIF launches 800G Coherent and Co-Packaging Framework projects

OIF launched two new projects – 800G Coherent and Co-Packaging Framework, availability of a new FlexE for 400ZR white paper, newly elected board members/positions and working group representatives.

800G Coherent

In scope for the 800G Coherent project is to define interoperable 800G coherent line specifications for campus and DCI applications. The resulting Implementation Agreement (IA) will:

  • Define single-lambda 800G coherent line interfaces for two applications
  • Amplified, single span, DWDM links up to 80-120km
  • Unamplified, fixed wavelength links of 2-10km
  • Support Ethernet client(s) (minimum 100GE) up to 800G aggregate bandwidth

“The next standardized coherent rate beyond 400ZR will be technically challenging with many factors to be considered,” said Tad Hofmeister, Technical Lead, Optical Networking Technologies at Google and OIF Vice President. “With the 800G Coherent IA, OIF is in a unique position to take a leadership role in defining interoperable 800G coherent line interfaces for various applications.”

Co-Packaging Framework IA

The Co-Packaging Framework IA, announced on November 10, 2020, will study the application spaces and relevant technology considerations for co-packaging of communication interfaces with one or more ASICs. A primary objective of this specification is to identify new opportunities for interoperability standards for possible future work at the OIF or other standards organizations. Upon completion, the work will be summarized in a Framework IA.

White Paper

A new OIF white paper addressing 400ZR applications requiring multiplexing of lower rate Ethernet signals (e.g. 100GE) and how to leverage FlexE for this service multiplexing is now available.

The OIF 400ZR IA includes mapping of 400G Ethernet signals as defined in IEEE 802.3, but not lower rate services such as 100G Ethernet. This white paper describes utilizing the OIF FlexE Implementation Agreement multiplexing of lower service rates, such as 100G and 200G Ethernet to a 400G frame that can be carried by 400ZR devices. Example profiles are provided to guide interoperability in common scenarios.

FCC's C-Band spectrum auction gets underway

 The FCC kicked off its auction of 280 megahertz of prime mid-band spectrum in the 3.7-3.98 GHz band—a portion of the C-band.  This is the FCC’s largest mid-band 5G spectrum auction to date.

“This is a big day for American consumers and U.S. leadership in 5G,” said FCC Chairman Ajit Pai.  “By freeing up this wide swath of critical mid-band spectrum, the FCC is paving the way for Americans to receive fast 5G wireless services.  Together with the recent success of our 3.5 GHz band auction, our work to auction the 2.5 GHz and 3.45 GHz bands in 2021, and the other ground-breaking spectrum auctions we’ve held since 2017, our 5G FAST Plan is in full swing.  American consumers and businesses will benefit from this FCC’s efforts for years to come.” 

Chairman Pai proposed and instituted a plan to repurpose the C-band quickly.  As a result, this mid-band spectrum will be available to deliver next-generation connectivity to American consumers and businesses years ahead of schedule.  The FCC successfully secured commitments from fixed satellite companies to move quickly out of the 3.7-3.98 GHz band and into the upper portion of the C-band, which will free up this crucial mid-band spectrum for 5G wireless services. 

The first round of the clock phase of the auction started on December 8th at 10 a.m. ET.  This auction will offer 5,684 new flexible-use overlay licenses based on Partial Economic Areas (PEAs) for spectrum in the 3.7–3.98 GHz band.  This spectrum holds the potential to be prime spectrum for 5G services given its combination of geographic coverage and capacity, and the FCC’s auction procedures will ensure the assignment to auction winners of contiguous spectrum blocks allowing wide channel bandwidths that support 5G deployment. 

Satellite operators currently using the C-Band have agreed to repack their operations out of the band’s lower 300 megahertz (3.7-4.0 GHz) into the upper 200 megahertz (4.0-4.2 GHz).  The first phase of this transition—the clearing of 120 megahertz of spectrum from 3.7-3.82 GHz in 46 of the nation’s top 50 PEAs—will conclude by December 5, 2021.  The second phase—clearing the lower 120 megahertz of spectrum in the remaining PEAs, plus an additional 180 megahertz from 3.82-4.0 GHz nationwide—will conclude by December 5, 2023.  

Optoscribe develops glass chip for low-loss coupling to silicon photonics

Optoscribe Ltd. introduced glass chip for low-loss coupling to silicon photonics (SiPh) grating couplers.

The new OptoCplrLT is designed to overcome fiber-to-SiPh photonic integrated circuit (PIC) coupling challenges to enable high volume automated assembly and help drive down costs. 

The device was created using Optoscribe’s proprietary high-speed laser writing technique. It features low-loss light turning curved mirrors, which are uniquely formed in the glass, to direct the light to or from SiPh grating couplers. This prevents the need for bend-tolerant fiber solutions, which are often expensive, challenging and have some significant limitations in size and profile.

To help address footprint challenges, OptoCplrLT has a low-profile interface of less than 1.5mm in height, which allows compact interface layouts that alleviate packaging constraints. It is also compatible with industry-standard materials and processes; for example, the glass chip has a coefficient of thermal expansion matched to the silicon chip, helping to maximise performance.

Russell Childs, CEO of Optoscribe, said: “With data center operators and transceiver manufacturers seeking innovative solutions to help address fiber-to-SiPh PIC coupling challenges, we are pleased to introduce OptoCplrLT™ to help meet market demands of performance, cost and volume, as well as helping to overcome such hurdles including SiPh transceiver packaging and integration.”


AWS previews Amazon HealthLake

AWS announced Amazon HealthLake, a HIPAA-eligible service for healthcare and life sciences organizations. 

Amazon HealthLake aggregates an organization’s complete data across various silos and disparate formats into a centralized AWS data lake and automatically normalizes this information using machine learning. The service identifies each piece of clinical information, tags, and indexes events in a timeline view with standardized labels so it can be easily searched, and structures all of the data into the Fast Healthcare Interoperability Resources (FHIR) industry standard format for a complete view of the health of individual patients and entire populations. 

“There has been an explosion of digitized health data in recent years with the advent of electronic medical records, but organizations are telling us that unlocking the value from this information using technology like machine learning is still challenging and riddled with barriers,” said Swami Sivasubramanian, Vice President of Amazon Machine Learning for AWS. “With Amazon HealthLake, healthcare organizations can reduce the time it takes to transform health data in the cloud from weeks to minutes so that it can be analyzed securely, even at petabyte scale. This completely reinvents what’s possible with healthcare and brings us that much closer to everyone’s goal of providing patients with more personalized and predictive treatment for individuals and across entire populations.”

The U.S. Senate 49-46 to confirm Nathan Simington to a seat on the Federal Communications Commission. He takes the seat previously occupied by Republican Mike O’Rielly. With Republican Ajit Pai leaving as well, the FCC will be split evenly between Democrats and Republicans, until President-elect Biden chooses a new chairman. 

Simington currently serves at the National Telecommunications and Information Administration as a Senior Advisor in the office of Assistant Secretary for Communications and Information.

Outgoing FCC Chairman Ajit Pai stated “I congratulate Nathan on his confirmation by the U.S. Senate and look forward to welcoming him to the Commission.  It has been the greatest honor of my professional life to serve at the FCC, and I am confident that Nathan too will enjoy the challenges and rewards of the job."  

Fireeye reports cyber attack by a nation state

FireEye confirmed that it was recently attacked by a highly sophisticated cyber threat actor in what it believes was as a state-sponsored attack. 

Kevin Mandia, FireEye's Chief Executive Officer,said the attackers tailored their world-class capabilities specifically to target certain Red Team assessment tools that the company uses to test its customers’ security. These tools mimic the behavior of many cyber threat actors and enable FireEye to provide essential diagnostic security services to our customers. None of the tools contain zero-day exploits. 

FireEye will now need to release the methods and means to detect the use of the stolen Red Team tools. This includes more than 300 countermeasures to minimize the potential impact of the theft of these tools. 

FireEye also said that, consistent with a nation-state cyber-espionage effort, the attacker primarily sought information related to certain government customers.
