OSFP MSA completes specification for 800G modules

The Octal Small Form Factor Pluggable (OSFP) Multi Source Agreement (MSA) group has published its OSFP 4.0 Specification for 800G OSFP modules. 

While the OSFP module was designed from the beginning to support 800G performance, the OSFP 4.0 specification adds support for dual 400G and octal 100G breakout modules with dual LC, dual Mini-LC, dual MPO and octal SN/MDC fiber connector options.

“At 800G, the number of use cases involving aggregation or breakouts are increasing,” said Andreas Bechtolsheim, OSFP MSA Chair. “Being able to use existing standard fiber connectors for these breakout ports is a key issue since it avoids the optical performance impact and cost of fiber adaptor cables, splitter cables or patch panels.”

“Cloud operators have deployed tens of millions of LC and MPO fiber connectors with existing optics transceivers,” said Sameh Boujelbene, Senior Director at Dell’Oro Group. “A smooth transition from single port to dual port 400G optics in the 800G form factor requires backward compatibility with this large installed base of fiber connectors.”

“The ability to do rolling networking upgrades in existing cloud data centers is essential since cloud data centers are always on,” said Alan Weckel, Founding Technology Analyst at the 650 Group. “As the Cloud grows in size, the majority of equipment installed goes into existing facilities, a very different dynamic compared to previous upgrade cycles. Being able to install new network switches without replacing millions of installed fiber connectors is one of the most important issues customers are facing as they transition to 800G optics form factor modules.”

“The OSFP 4.0 specification offers customers compatibility with existing fiber connectors and a broad choice of potential optical breakout options, which will likely become even more important with the upcoming early adoption of 800GbE data center switching starting next year,” said Seamus Crehan, President of Crehan Research.

With the 800G OSFP module specification completed, the OSFP MSA has sponsored a working group that is defining 200G/Lane electrical specifications to support 1600G OSFP modules. When this activity is completed, this development will be merged into a future OSFP 5.0 Specification.

“We have received strong interest from OSFP MSA members to start the 200G/Lane Electrical Signaling Group,” said Brian Kirk, Director of Engineering, Amphenol Corp. “Based on the work done so far, we are confident that the OSFP module will be able to support 200G electrical signaling speed per lane in a backward compatible fashion.”

“1600G-OSFP enables next-generation switch designs with up to 57.6T bandwidth per rack unit,” said Nathan Tracy, Technologist at TE Connectivity. “It is remarkable that the OSFP can support this level of bandwidth density in a pluggable form factor.”

Vodafone tests multi-vendor RAN intelligent controller

Vodafone, in conjunction with Cohere Technologies, VMware, Capgemini Engineering, Intel and Telecom Infra Project (TIP), demonstrated an Open Radio Access Network (RAN) platform capable of increasing the capacity of a 5G cell site by two-fold using a programmable, Artificial Intelligence (AI)-based RAN Intelligent Controller (RIC).

Specifically, he companies showed the first demonstration of 5G Multi-User MIMO (MU-MIMO) – providing more capacity at a single cell site – running on a RIC located at a multi-vendor Open RAN test site.  MU-MIMO apportions ample bandwidth to individual users connected to the same mobile site and is considered the pivotal technique to boost cell capacity in future 5G networks. It is a major development in supporting the insatiable demand for faster and more responsive digital connections to deliver high definition graphics, virtual reality, cloud and IT applications.

Based on the performance of Cohere’s Spectrum Multiplier MU-MIMO scheduler in the trial, when the technique is commercially deployed in a low-band (e.g. 700MHz) network, users will benefit from up to 2x the capacity achieved using traditional MIMO. This software can be extended to Massive MIMO in mid-band (e.g. 3.5GHz) networks in order to push capacity gains towards 4-5x.

Corning intros bendable SMF-28 optical fiber

Corning introduced its SMF-28 Contour optical fiber featuring enhanced bend resilience, network compatibility, and industry-leading low loss characteristics.


  • Superior bendability designed to reduce the impact of errors during installation and optimize reach in densely cabled environments where 5G networks are being deployed. SMF-28 Contour fiber is an ITU-T G.657.A2 fiber that has 10 times the macrobend resilience of G.652.D fibers and seven times the macrobend resilience of G.657.A1 fibers. The associated increase in microbend resilience enables dense, high-fiber-count cables needed to meet the demands of future high-capacity networks.
  • Exceptional compatibility with legacy networks while providing superior bend protection, which can mean up to 50% faster installation by minimizing corrective splice-loss work. Other G.657.A2 fibers also provide bend protection but with a compromised, lower mode field diameter. SMF-28 Contour fiber does not compromise, providing both G.657.A2 bend protection and a matched 9.2-micron mode field diameter in the same product.
  • Wide spectrum and industry-leading low-loss transmission across all the wavelengths that constitute the communication systems of today and tomorrow. First, SMF-28 Contour fiber’s industry-leading low attenuation delivers 10% longer reach in all networks and up to 20% wider access-network coverage. Second, SMF-28 Contour fiber’s bend loss protection enables up to twice the network reach in new long-wavelength FTTH systems. Together, these features enable larger FTTH subscriber areas and greater revenue potential.

SMF-28 Contour fiber is available in a standard 242-micron configuration and a smaller 190-micron configuration. 

Corning says smaller-diameter designs are increasingly important because while bandwidth demands have grown, the space available for network infrastructure has not. The 190-micron version of SMF-28 Contour fiber enables smaller cables with higher fiber counts – maximizing use of existing infrastructure

“Corning’s revolutionary SMF-28 Contour optical fiber is the latest example of our ability to solve tough industry challenges,” said Dr. Bernhard Deutsch, vice president and general manager, Corning Optical Fiber and Cable. “Operators today are looking to deploy future-ready networks as efficiently as possible, often in densely cabled environments, and we’ve designed this new product to answer those needs. Fifty years after Corning scientists invented the first low-loss optical fiber, we’re proud to help drive a new era of industry growth and network transformation.”

Smartoptics Group AS completes IPO

 Smartoptics Group AS completed an initial public offering of its shares on Euronext Growth in Oslo, Norway.  The public listing follows a successful private placement raising gross NOK 100 million in new equity.

“The IPO is a milestone in Smartoptics’ history. We have over the last year experienced tremendous traction in the market, as we have developed technology and services that are perceived as more innovative and flexible than those of our competitors. As a listed company, we now have added fuel to power our ambitions of reaching USD 100 million in revenue and 15-20 percent EBITDA margin by 2025-2026,” said CEO Magnus Grenfeldt.

In 2020, Smartoptics had a revenue of USD 34.8 million and an EBITDA margin of 6 percent. The start of 2021 has been strong, with first quarter revenues growing 52 percent to reach USD 10 million and an EBITDA margin of 13.8 percent.

“We have positioned ourselves perfectly in this market. We have become a preferred vendor for many small and medium-sized operators and enterprises. Our technology, size and business culture make it possible for us to maneuver faster than the giants of the industry, and most of the other medium-sized players have been acquired. Hence, we face limited competition in our segment,” said Grenfeldt.

The Smartoptics shares were sold at NOK 10.38 per share in the private placement, equivalent to a post-money capitalization of approximately NOK 1 billion. The transaction included a secondary share sale of NOK 150 million. Among the investors are Danske Invest, Ã…landsbanken and Varner Invest.
