Several types of fiber optic cables are commonly used today, each designed to meet specific networking requirements. Single-mode fiber optic cables are prevalent for long-distance transmissions. They have a smaller core size, allowing a single mode of light to travel, reducing signal attenuation and enabling higher bandwidth over extended distances. Multi-mode fiber optic cables, with a larger core size, are suitable for shorter distances and are often used in local area networks (LANs). They support multiple modes of light, offering cost-effective solutions for high-speed data transmission within confined spaces. Within these broad categories, various subtypes such as OM1, OM2, OM3, and OM4 exist, indicating different performance characteristics like bandwidth and modal dispersion. Additionally, armored fiber optic cables feature additional protection with metal armor, enhancing durability and resistance to environmental factors. Understanding the distinctions between these fiber optic cable types is essential for network professionals to choose the most suitable option based on the specific requirements of their infrastructure.
