Few-mode fibers (FMFs) constitute a class of optical fibers designed to propagate a limited, predefined number of light modes. Positioned between single-mode fibers (SMFs), which support only one mode, and multimode fibers (MMFs), which accommodate numerous modes, FMFs offer a balanced solution. Mode field diagram of FMFs Applications FMFs find utility across diverse sectors, notably in […]
The global cloud market is experiencing remarkable growth, with enterprise spending on cloud infrastructure services reaching nearly 20 billion from the same period in 2024, marking the third consecutive quarter of 24-25% year-over-year growth. The driving force behind this surge is Generative AI (GenAI), which has propelled cloud providers’ quarterly revenues up by 100 billion quarterly […]
In the era of explosive AI computing power and 5G-A, network traffic is surging, placing immense pressure on optical networks. Traditional non-coherent optical modules, with their low bandwidth and simple modulation methods, can no longer meet the demands of high-speed, long-distance, and high-density transmission. With the continuous maturation of key technologies such as digital signal […]
In early 2021, Broadcom’s CEO, Hock Tan, unveiled Co-Packaged Optics (CPO) at the J.P. Morgan Auto/Tech Forum, marking a paradigm shift in networking technology. Since then, CPO has swiftly transitioned from a conceptual vision to tangible demonstrations, exemplified by Broadcom’s recent showcase of a 6.4 Tbps optics integration at OFC 2025, tailored for custom AI […]
Point-to-point cabling solutions are typically used in rack-level interconnection scenarios. They are designed to meet the direct interconnection needs of devices within the same physical rack. However, this architecture has spatial limitations. When devices are dispersed across different functional areas of a data center or are geographically distant from each other, it is recommended to […]
In the construction of high-speed networks in data centers, high-density fiber optic cabling has become mainstream. How to achieve efficient and flexible connections within limited cabling space? The 16-fiber MPO/MTP to 2x 8-fiber MPO/MTP fiber optic patch cord, with its high-density advantage, has become an important tool for optimizing network architecture. What is an MPO Fiber Optic Patch […]
What are the application advantages of 800G optical module technology? As a disruptive force in data-center and high-performance-computing environments, 800 Gb/s optical-module technology is steering the industry toward higher bandwidth, lower cost, and reduced power consumption. The key benefits are: Dramatic increase in switching bandwidth: Compared with 400 Gb/s-port systems, 800G technology doubles the aggregate […]
A recent report by Counterpoint Research forecasts a remarkable surge in the market for Near-Packaged Optics (NPO) and Co-Packaged Optics (CPO) solutions, which are expected to be the primary drivers of in-package optical IO technology revenues over the next decade. According to the report, OBO (On-Board Optics), CPO, and NPO solutions are projected to achieve […]
With the widespread adoption of 100G PAM4 modulation technology, current 400G/800G optical modules extensively utilize the 4×100G PAM4 and 8×100G PAM4 architectures. Against this backdrop of technological evolution, traditional 4×25G NRZ schemes (e.g., 100G QSFP28 SR4) or 4×50G PAM4 schemes (e.g., 200G QSFP56 SR4) face three critical challenges: firstly, rate mechanism incompatibility causing link negotiation […]
The global data center industry is poised for sustained expansion driven by escalating investments in artificial intelligence (AI) infrastructure, with worldwide capital expenditures (CAPEX) projected to surpass ＄1 trillion by 2029, reflecting a compound annual growth rate (CAGR) of 21% over the forecast period. This growth trajectory is underpinned by the proliferation of accelerated servers […]
