In modern data centers, high-performance computing clusters, and cloud computing platforms, high-speed, low-latency, and stable interconnections are required between servers, switches, and storage devices. Among the many interconnection solutions, DAC (Direct Attach Copper) and AOC (Active Optical Cable) are two of the most widely used cable solutions. While they may appear similar, they each have […]
As data centers continuously evolve towards higher bandwidth and larger scale, 800G optical modules have become critical infrastructure supporting AI computing, high-performance computing, and cloud services. Their importance lies not only in the leap in transmission rates but also in the significant improvement in data exchange efficiency and density through technological integration, reducing per-bit power […]
With the continuous development of AI and big data technologies, the demand for 800G optical transceiver modules in data centers and communication networks is constantly increasing. Among them, the 800G OSFP SR8 utilizes an 8-channel full-duplex transceiver design, capable of meeting the requirements of short-reach data center and cloud computing networks, offering high cost-effectiveness and […]
A high Bit Error Rate (BER) in 800G optical modules is a multifaceted and complex issue that requires a systematic approach for step-by-step troubleshooting. It is recommended to follow an order from simple to complex to efficiently locate and resolve the problem. Check Optical Power and Module Status Use the command line interface (CLI) to […]
The Octal Small Form Factor Pluggable (OSFP) module, widely adopted for high-speed optical interconnects, is available in three primary structural forms that address different thermal and mechanical requirements: Closed Top, Finned Top, and Riding Heatsink (RHS). Finned Top Heatsink (Open Top Heatsink) In contrast, the finned top design exposes heatsink fins on the upper surface. […]
Q1: What are the speeds supported on an 800G optical module? 800G optical module can support a range of speeds, depending upon their type. They can support: A single port of800 Gbps Two ports of 400 Gbps Eight ports of 100 Gbps Q2: What is the channel distribution of the 800G optical module? The 800G […]
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 […]
