Worldwide fiber-optic cable shortage looms over 5G, data center infrastructure rollouts

The fiber crunch is here, according to new research from market intelligence analyst Cru Group. A worldwide shortage of fiber-optic cable has driven up product pricing and lengthened lead times on supply, casting a shadow over ambitious industry plans for advanced telecommunications infrastructure rollouts. Governments around the world have set ambitious targets for the rollout of superfast broadband and 5G infrastructure, both of which of course require vast quantities of fiber-optic cable to be laid underground. At the same time, Amazon, Google, Microsoft and Facebook owner Meta are in the process of expanding their data center footprints around the world to meet soaring demand, including globe-spanning deployments of subsea fiber-optic cabling. Prices for fiber have now reached their highest level since July 2019. North America has been less severely impacted than Europe, China and India — but that may not be for long.

White Paper: Understanding the Differences Between OM4 and OM5 Multimode Fiber

Multimode fiber is a staple of fiber-optic cable infrastructure in data centers and campus networks. The ISO/IEC 11801 standard defines five classes of multimode fiber: OM1, OM2, OM3, OM4 and OM5. In this white paper, we will review the basics of multimode fiber and the evolution of the different fiber standards. We’ll discuss the differences between OM4 and OM5 and clear up the misconceptions, discussing when OM5 is an appropriate choice and when OM4 will work just fine.

TIA Issues Edge Data Center Addendum to ANSI/TIA-942-B Data Center Infrastructure Standard.

TIA has released the Edge Data Center Addendum to the ANSI/TIA-942-B data center infrastructure standard which defines requirements for newer “edge” or “micro” data centers, which often come in prefabricated enclosures that are significantly smaller than the more traditional sprawling warehouses. The TIA-942-B-1 addendum is a significant step for the globally deployed standard because, as 5G services expand, new applications are emerging and the exponential growth of connected IoT devices are requiring more of the “intelligence” to be closer to the application end user and their devices. The more local processing of data helps applications to meet their latency and performance requirements as well as reduce the volume of raw data uploaded into the cloud.

Senko acquires optics-component manufacturer CudoForm

Senko Advanced Components has acquired CudoForm, a company that designs and manufactures high-precision micro-optic components with applications in data communications, consumer photonics, and biosafety. CudoForm’s CEO says the combined organization will ‘provide novel solutions that meet the demanding requirements of this tight-spaced packaging and difficult-to-integrate photonics ecosystem.
