Outdoor optical cables, also known as outdoor fiber optic cables, are designed to withstand harsh weather conditions and other outdoor environmental factors. There are several different models of outdoor optical cables, each with its own unique characteristics and uses. In this article, we will discuss the most common models of outdoor optical cables.
Loose Tube Cable: The loose tube cable is the most common type of outdoor optical cable. It consists of several optical fibers that are contained in individual protective tubes, which are then gathered together into a single cable. The tubes are filled with a gel that provides additional protection against moisture and other environmental factors. Loose tube cables are designed for use in long-haul telecommunications networks, as well as for outdoor installations such as aerial, underground, and direct burial.
Ribbon Cable: The ribbon cable is a flat, ribbon-shaped cable that contains multiple optical fibers. The fibers are arranged in parallel rows and held in place by a matrix material. Ribbon cables are designed for use in high-density environments such as data centers, where space is limited and multiple fibers need to be bundled together.
Central Loose Tube Cable: The central loose tube cable is similar to the loose tube cable, but it has a central strength member that provides additional support and protection to the fibers. The fibers are contained in individual tubes, which are then gathered around the central strength member. Central loose tube cables are designed for use in long-haul telecommunications networks, as well as for outdoor installations such as aerial, underground, and direct burial.
Armored Cable: The armored cable is an outdoor optical cable that is reinforced with a layer of armor made from steel or other materials. The armor provides additional protection against crushing, impact, and other physical damage. Armored cables are commonly used in industrial environments, such as oil and gas fields, where the cables may be subjected to harsh conditions.
ADSS Cable: The all-dielectric self-supporting (ADSS) cable is an outdoor optical cable that is designed to be hung in the air, typically between utility poles. The cable is self-supporting, meaning that it does not require any additional support structures such as messenger wires. The cable is designed to withstand the stresses of wind and ice, and it is typically used in high-voltage power transmission applications.
Blown Fiber Cable: The blown fiber cable is an outdoor optical cable that consists of a microduct and a bundle of individual fibers. The fibers are blown through the microduct using compressed air, which allows for easy installation and the ability to add or remove fibers as needed. Blown fiber cables are commonly used in metropolitan area networks (MANs) and other urban installations, where the cables may need to be installed in tight spaces or through existing ducts.
Hybrid Cable: The hybrid cable is an outdoor optical cable that contains both optical fibers and copper conductors. The copper conductors are typically used for power transmission or for carrying signals such as Ethernet or telephone lines. Hybrid cables are commonly used in industrial and utility applications, where both fiber and copper infrastructure may be needed.
In conclusion, outdoor optical cables are essential for telecommunications networks, data centers, and other applications that require high-speed data transmission over long distances. There are several different models of outdoor optical cables, each with its own unique characteristics and uses. The selection of the appropriate cable model depends on the specific needs of the application, such as the distance of the transmission, the environmental conditions, and the required bandwidth. By understanding the different models of outdoor optical cables, network installers and engineers can make informed decisions and ensure that their networks are reliable and efficient.
