As data centers scale to 800G and 1.6T for AI workloads, traditional pluggable optics face rising power and thermal challenges. This drives three new packaging and interconnect architectures. CPO (Co-Packaged Optics) – Moves optical engines close to the switch ASIC, drastically shortening electrical paths. This reduces or eliminates high-power DSP/retimer functions, delivering superior power efficiency and […]

Upgrading to a fiber‑based network seems straightforward until you consider the existing infrastructure. Many enterprise environments still rely on copper cabling and thousands of Ethernet‑connected devices that cannot be replaced overnight. As organisations seek to increase bandwidth and support future growth, Fiber to the Desk (FTTD) has emerged as a practical path forward. Why FTTD […]
When network issues arise in AI data centers, switches, transceivers, and software settings are often the first suspects. However, one tiny culprit is frequently overlooked: dirty fiber connectors. In 400G and 400G networks, even minuscule dust particles can degrade signals, increase error rates, and cause link failures. As AI clusters scale up, fiber cleaning has […]
With the continuous advancement of optical fiber sensing and transmission technology, we are increasingly facing extreme application scenarios: the blazing core of jet engines, cryogenic environments as low as -269°C, highly corrosive chemical storage tanks… In these environments, ordinary optical fibers are fragile. When the temperature exceeds the critical point of 400°C, conventional organic coatings—whether […]
Massive AI clusters are pushing traditional pluggable optics to their physical limits in power, cooling, and density. As traffic surges, the industry requires a solution that balances high-performance integration with the operational ease of standard modules. This article explores how XPO (eXtra-dense Pluggable Optics) bridges this gap, providing a transformative path for scaling AI infrastructure […]
Modern data center interconnects (DCI) often require high-capacity optical links over tens to hundreds of kilometers. Traditional IM-DD (Intensity Modulation with Direct Detection) modules—using NRZ or PAM4—are simple and cost-effective for short distances, but they face limitations in dispersion tolerance, noise resilience, and spectral efficiency over longer spans. Coherent optical modules overcome these limitations by […]
