Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection. The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, ch...
Introduction In an era dominated by exponential data growth, optical switches have emerged as the backbone of modern communication systems, enabling lightning-fast data transfer across global networks. As 5G, AI, and IoT demand unprecedented bandwidth, the $3.2 billion optical switching market (2023) is poised to transform industries from telecommunications to quantum computing. This article explores the latest advancements, real-world applications, and emerging trends shaping optical switch technology in 2024. 1. How Optical Switches Work: Principles and Key Architectures Optical switches manipulate light signals without converting them to electrical form, minimizing latency and energy consumption. Modern designs leverage three core technologies: MEMS-Based Switches : Micro-electromechanical mirrors physically redirect light paths, offering low insertion loss (<1 dB) and scalability for data centers. Silicon Photonic Switches : Integrated waveguide circuits enable sub-...
