Arista's Jayshree Ullal, 2023 Network Identity Redefined for Zero Trust Enterprises


The perimeter of networks is changing and collapsing. In a zero trust network, no one and no thing is trusted from inside or outside of the enterprise network without verification or network access control (NAC). However, for years, organizations have been saddled with bolt-on NAC  technologies that deliver cost complexity while failing to be effective. Instead, security-conscious organizations are shifting to a “microperimeter” enterprise that embeds security into the network infrastructure as the proactive way to defend today’s wider attack surface.

Coherent Awarded Phase 2 of IARPA Resilience Program for High-energy Rechargeable Lithium-Sulfur Batteries 


The goal of RESILIENCE is to increase energy densities by up to 2x and calendar life by up to 10x beyond the performance of commercial solutions. The technology has a broad range of rapidly growing applications, including the electrification of vehicles and the transportation infrastructure, clean and renewable power storage for energy utilities and microgrids, portable consumer electronics, wearable devices for health monitoring and public safety, and harvested energy storage for the commercial and industrial internet of things. In Phase 1 of the program, Coherent demonstrated exceptional performance with coin cell batteries. In Phase 2, the objective is to scale up the technology to large-format cells with energy densities of up to 450 Wh/kg. (Continued)...

ETSC Bridge Health Monitoring Using Distributed Fiber Optic Sensing

Real Time Reconstruction of the 3D strain field of the bridge

Due to the frequent occurrence of bridge accidents in recent years, bridge safety monitoring has attracted increasing attention. Usually there are dozens of types and thousands of sensors distributed on a bridge, which are used to monitor the strain, inclination, displacement, deflection, acceleration, temperature and humidity of the bridge. Compared with traditional monitoring methods, distributed optical fiber sensing technology can obtain thousands of sensing points on a single optical fiber for simultaneous measurement and accurately locate the fault location. (Continued)...

Hirose Electric Partners with TraceParts


The partnership includes data on over 10,000 CAD models including board-to-board connectors and FPC connectors of Hirose products. This enables designers to easily search for their desired product on TraceParts and, once registered to the platform, instantly download the data they need, free of charge. The digital models are available in over 70 CAD formats including STEP, Parasolid, SolidWorks, AutoCAD, Inventor, Fusion 360, Creo, and more. This collaboration helps streamline and reduce design time, allowing engineers to focus on innovation and development. (Continued)...

Hisense Broadband Launches 800G Linear Drive Optical cable for AI/ML Applications 


The industry has been looking for a low-power, low-cost, low-latency linear drive solutions to address the power and latency challenges posed by DSP/CDR platform. Hisense Broadband named this new product as Optical Direct Attach Cable (oDACTM) as it can be considered as a counterpart of Direct Attach Cable in optical domain with an extended transmission reach. Hisense's linear drive oDAC eliminates the CDR/DSP to reduce power consumptions, and improves the system linearity by delicate signal integrity design. By leveraging the increasingly powerful equalization and compensation capabilities of the latest switch, 5e-7 pre-FEC BER floor was achieved over 50-meter OM4 multimode fiber with ~10dB channel loss, and no uncorrectable post FEC error happened in the system traffic test. The power consumption is as low as 4 watts per 800G OSFP end. (Continued)...


Overall datacom speed requirements have become high enough to benefit from the technology’s strengths. Silicon photonics allows for much higher photonic complexity than discrete designs, delivering improved performance, better power efficiency, and better cost at scale. This is more important today than ever, because of the increasing data-transfer and power-consumption requirements driving companies toward innovative ways to compute, store, and move data faster. (Continued)...
