The XPO optical transceiver, with a single-module bandwidth of 12.8 Tbps, increases the front-panel density of switches to 4 times that of OSFP solutions. While high-density switch ports boost computing power, they also introduce new challenges for fiber optic cabling. This article briefly introduces the MPO pre-terminated trunk cables that support XPO optical modules. What […]
In modern data centers—especially in AI and 400G/800G environments—fiber cabling is no longer just about connectivity. Choosing the wrong MTP®/MPO cable can lead to link failures, wasted fibers, and costly rework. This guide focuses specifically on MTP®/MPO-12 cables, explaining their matching logic with various transceivers and providing clear selection recommendations. 1. Core Matching Rule The relationship between […]
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 […]
