Innovating the Path to Terabit Speeds: IEEE, Senko, and US Conec Weigh In

To support emerging technologies and ever-increasing amounts of data, large hyperscale and cloud data centers like AWS, Google Cloud, Meta, Microsoft Azure, and Equinix have quickly migrated to 400 Gigabit speeds for switch-to-switch links and data center interconnects, as well as for switch-to-server breakout configurations. Now these big-name data centers are gearing up to deploy 800 Gig and looking ahead to 1.6 and 3.2 Terabit speeds, while 400 Gig starts making its way into large and even mid-sized hosted and enterprise data centers.

White Paper: Infrastructure Solutions for Edge Networks

Deploying and maintaining an edge data center requires specific focus on both communications infrastructure as well as the equipment that houses and protects that infrastructure. Add to the mix that the term “edge” can be defined in a number of ways, and meeting customer expectations requires significant planning and project management during an edge deployment. This On Topic Report, focused on Edge Networking, acknowledges the reality that edge can mean different things to different users. In that vein, it provides practical information about the edge’s place in the larger network landscape, and delivers useful information about deploying the right solution for users’ needs.

5 ways to reduce the carbon impact of smart building technologies

While smart building technologies are vital to improving building efficiency, the actual technology products deployed throughout a smart building are mostly made up of fossil fuel derivatives and mined from non-renewable resources—from the IoT devices to the networks that connect them. That inherently makes it unfeasible for most of these products to be considered low-carbon construction materials. Even so, there are ways to reduce their impact. CommScope’s Ronna Davis covers five options.

Quick disconnect couplings enable efficient data center liquid cooling

Danfoss Power Solutions’ new family of universal quick disconnect couplings for data center liquid cooling applications helps data center operators meet the thermal management challenges of more powerful chips, denser racks, and heavier workloads through reliable, leak-free, efficient operation.The UQD couplings are ideal for in-rack liquid cooling applications that use smaller hose lines offering a 25% higher flow rate than OCP community standards and  a low pressure drop which improves system efficiency and reduces in-rack power consumption, providing long-term cost savings.

US Conec barks back at Senko in VSFF connector patent scrap

US Conec filed a response to a Senko Advanced Components suit that alleges US Conec violated SENKO patents on very small form factor (VSFF) fiber-optic connectors denying the allegations and contains allegations that Senko violated US Conec patents. SENKO, in a written statement to Lightwave reaffirmed that it expects to triumph in court. Both companies make VSFF connectors and associated adapters – the CS, SN, and SN-MT connectors in SENKO’s case, and the MMC and MDC connectors in US Conec’s.

Return Loss: Causes and Testing Procedures

Return loss is the ratio of signal power injected from a source compared to the amount that is returned or reflected back toward the source. It is a critical performance parameter in both copper twisted pair and fiber optic cabling systems, because it can interfere with the transmitted signal and can contribute to an increase in the measured insertion loss (the amount of power that a that a signal loses as it travels along a cable link).
