Why E-Tube Cables Offer a Promising Alternative to Copper and Optical Interconnects

Image
E-Tube cables are  a promising alternative to copper and fiber-optic cables for hyperscale data centers  because they are: Energy efficient : E-Tube cables are about 50% more energy efficient than co-packaged optics and 75% more efficient than traditional re-timed optics.   Cost-effective : E-Tube cables can be produced at similar prices to copper cables.   Scalable : E-Tube cables can scale to multi-terabit network speeds without a change in channel loss.   Lightweight : E-Tube cables are 50% thinner than copper and are less bulky.   Easy to route : E-Tube cables have a greater bend radius, which improves routeability and reduces rack congestion.   Easy to service : E-Tube cables are easier to service in the field.   E-Tube cables use radio wave transmission over a dielectric waveguide made of plastic, such as low-density polyethylene (LDPE). They are designed to meet the performance needs of AI data centers, and are a good choice for in-rack and adjacent-rack deployments.   E-Tube te

Eventhough options are available - sub-sea cable alternative should not be at serious attention note : majority of the internet relies on the subsea cabling

Image
The Importance of Subsea Cable Networks The recent conflict in the Middle East has brought renewed attention to the critical role of subsea cable networks in global internet infrastructure. These cables, which carry approximately 95% of all international Internet traffic, are facing potential risks due to the volatility in the region. This situation has prompted enterprises and providers to consider alternative options, such as satellite and ground cable systems, which were previously deemed less favorable due to cost and performance factors. Driving Factors for Change Several key factors are contributing to this shift in perspective: Geographical Convergence: Many critical cables connecting Asia, Africa, the United States, Northern Europe, and South America converge at choke points near the Red Sea and Mediterranean Sea. Recent Cable Disruptions: While the cause of recent subsea cable cuts remains unconfirmed, these incidents have highlighted vulnerabilities in the system. Repair Chal

Fragile Connections: Why Subsea Cables are the Weak Link in Global Infrastructure

Image
Concern is rising over global risks to submarine communications cables. How justified are those fears? Subsea cables are the lifeblood of digital infrastructure, forming the unseen backbone that enables data centers to provide seamless connectivity across continents. Any disruption – whether from geopolitical conflict, accidents, or natural disasters – can send ripples through the data center ecosystem, affecting uptime, service delivery, and ultimately, the stability of global digital communications. In February 2024, the disruption of three submarine communications cables in the Red Sea highlighted the ongoing concerns over the vulnerability of the world’s fragile data networking connections. The anchor of a cargo ship that was attacked by Houthi militants was deemed to be the most likely cause of damage to the Seacom, TGN, AAE-1, and EIG cables, which play a vital role in connecting Europe and Asia’s infrastructure. Once cut, a submarine cable can take months to repair .
