In 2025, substantial investments by hyperscalers in AI infrastructure propelled shipments of 800G PAM4 chipsets to nearly triple, with sales revenue more than doubling year-over-year. These investments continue to escalate in 2026, leading to revised upward forecasts for both 800G and 1.6T optical transceiver shipments. Industry projections now indicate that 800G shipments will more than […]
In the field of high-speed optical interconnect, CPO, NPO, LPO, and OCS represent different technologies or packaging forms. The following is a detailed introduction to each of them: CPO (Co-Packaged Optics): This is a new type of optoelectronic integration technology. By packaging the optical module and the switching chip closely together, it significantly reduces the […]
An Optical Loss Test Set (OLTS) is an instrument used to verify the performance and quality of fiber-optic networks across various applications and industries. It plays a fundamental role in field testing, often being employed more frequently than other tools such as the Optical Time Domain Reflectometer (OTDR). This preference stems from the fact that […]
What is Multimode Fiber (MMF)? Multimode fiber (MMF) has a core diameter of 50 µm or 62.5 µm, enabling it to support multiple propagation modes. These modes travel at different speeds and phases, which can lead to issues such as signal delay, spectral broadening, and dispersion over long-distance transmission. As a result, multimode fiber is […]
MPO (Multi-Fiber Push-On) technology has become a critical component in today’s high-density fiber optic networks. Among the various MPO products, MPO loopback modules play a vital role in testing and diagnostics, while MPO trunk and breakout cables enable efficient and scalable connectivity. MPO loopback modules are passive devices designed to facilitate testing of optical transceivers […]
Optical Time Domain Reflectometers (OTDRs) are essential instruments for evaluating the integrity and performance of fiber optic networks. They provide a detailed visual representation—known as a trace—of a cable’s condition, helping technicians verify installations, locate faults, and monitor changes over time. However, incorrect interpretation of OTDR results can lead to significant operational losses, including wasted […]
This article outlines the key characteristics and applications of multimode fiber grades, ranging from OM1 to OM5. From OM2 onward, the core size remains consistent at 50 µm. OM3 fiber supports 10 GbE transmission over distances of up to 300 meters. While it can also accommodate 40 and 100 GbE across 100 meters, its most […]
Although Cat 5e and Cat 6 cables share many characteristics, several important differences set them apart. To grasp these distinctions, it helps to first understand what the cables have in common as well as their individual features. Overview of Each Cable Type According to technical resources, the Cat 5e standard emerged in the late 1990s […]
After inserting an optical module, the switch interface indicator does not light up, and the link cannot communicate normally. In device interconnection, this often indicates that the interface failed to start up properly. If the status shows „DOWN (Transceiver Type Mismatch)“ when checked, it is usually not due to hardware damage but is more likely […]
On January 6, 2026, CES 2026, the world’s largest and most influential technology event, officially opened in Las Vegas. NVIDIA unveiled its next-generation artificial intelligence infrastructure platform—the Rubin platform. At the heart of this platform is the brand-new superchip, Vera Rubin, marking another significant leap for NVIDIA in the field of high-performance computing and once […]
