Exceptional speed, resilience and low latency are critical for data center interconnect, with hollow core fiber (HCF) enabling significantly improved performance for these and other KPIs over traditional single-mode fiber (SMF). The technology’s trial and rollout is a priority deployment in sectors such as AI, quantum communications and cloud infrastructure. But testing HCF u...

As hyperscale facilities shift toward 1.6T Ethernet and prepare for 3.2T, the methodology for network testing must be upgraded. Validation of High-Speed Ethernet (HSE) and data center fabrics needs to take place across all layers, from OSI Layer 0 (the medium) to 7 (the application, including security). This means that we need to not only […]

NetSecOps is being embraced by a growing number of organizations, as economies of scale, cross-training opportunities, streamlined incident response, and improved visibility demonstrate the value of this model. At the same, the priorities and workflows of NetOps and SecOps must remain distinct to ensure both security and performance objectives are consistently met. Joining fo...

Advances are taking place across a wide range of technologies. At ECOC 2026, we saw leaps forward in high-speed Ethernet (HSE), co-packaged optics (CPO) and silicon photonics (SiPh), along with fiber density, multifiber technologies, and alternative designs such as hollow-core fiber (HCF), alongside advances in peripheral but critical systems like quantum security. This is dr...

Pluggable coherent optics have come a long way in a short time. Coherent transmission once lived on custom line cards, engineered end-to-end at high cost in a closed ecosystem. CFP-based 100G coherent pluggables changed that, and since then a healthy multi-vendor ecosystem of coherent DSP, photonics, and module vendors has grown around common MSA and […]
