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 […]
Photoelectric Composite Cable PoF (Power on Fiber) is a type of composite cable that integrates optical fibers and power-transmitting copper wires, capable of simultaneously providing data transmission and remote power supply for devices. In scenarios where it is not easy to obtain power at the AP end, the photoelectric composite cable can be used to […]
As data centers face growing demands for bandwidth and port density, traditional cabling solutions are encountering dual challenges of space and efficiency. If you are planning or upgrading your data center infrastructure, ultra-small form factor, high-density fiber optic connectivity solutions will become a top priority. This article introduces the MMC connector series products, including MMC […]
In the field of optical communications, dBm, mW, and dB are three commonly used units. Understanding the relationship between them can help engineers make more precise judgments when designing and optimizing optical communication systems. This article briefly introduces the definitions and interrelationships of these three. Relationship between dBm and mW dBm (decibel-milliwatt) and mW (milliwatt) […]
