Briefly Describe The Types and Characteristics of Outdoor Fiber Optic Cable
Outdoor fiber optic cables are strands of glass or plastic that are used to transmit data over long distances. These cables are made up of extremely thin strands of glass or plastic, known as optical fibers, which are encased in the protective sheathing. The fibers are arranged in a bundle, called a cable core, which is then surrounded by additional layers of protective material to create the final cable.
Fiber optic cables are well-suited for outdoor use because they are immune to electromagnetic interference, making them ideal for transmitting data over long distances. They are also much thinner and lighter than traditional copper cables, making them easier to install and maintain. Additionally, fiber optic cables can transmit data at much higher speeds than copper cables, making them the preferred choice for many applications.
Advantages Of Outdoor Fiber Optic Cable
One of the main advantages of outdoor fiber optic cables is their ability to transmit data over long distances without the need for signal amplification. This is because the signals transmitted through fiber optic cables do not degrade over distance, unlike electrical signals transmitted through copper cables. This means that fiber optic cables can be used to connect two points that are far apart, without the need for intermediate signal boosters.
Another advantage of outdoor fiber optic cables is their resistance to interference from external sources. Because the signals transmitted through fiber optic cables are light-based, electromagnetic interference does not affect them. This makes them ideal for use in environments where there is a high level of electromagnetic interference, such as near power lines or electrical equipment.
One of the main challenges of using outdoor fiber optic cables is their vulnerability to damage from the environment. Because the fibers are made of glass or plastic, they can be easily damaged by moisture, temperature changes, or physical stress. This is why outdoor fiber optic cables are encased in the protective sheathing, which helps to protect the fibers from damage.
Types Of Outdoor Fiber Optic Cable
There are several different types of outdoor fiber optic cables, each designed for specific applications and environments. The most common type is called loose tube fiber optic cable, which is designed for use in aerial or underground installations. This type of cable consists of a central tube called the loose tube, which is filled with optical fibers. The loose tube is surrounded by a layer of water-blocking gel, which helps to protect the fibers from moisture. The cable is then surrounded by additional layers of protective material, such as aramid yarn, to provide additional strength and protection.
Another type of outdoor fiber optic cable is called tight buffer fiber optic cable. This type of cable is similar to loose tube fiber optic cable, but it has a layer of protective material, called a buffer coating, around each fiber. This provides additional protection for the fibers, making them more resistant to damage from bending or crushing. Tight buffer fiber optic cables are often used in applications where the cable will be subjected to frequent bending or crushing, such as in cable trays or conduits.
There are also several specialized types of outdoor fiber optic cables, such as armored fiber optic cable and breakout fiber optic cable. Armored fiber optic cable is encased in a protective metal sheath, which makes it extremely durable and resistant to damage. It is often used in applications where the cable is exposed to severe physical abuse, such as in underground installations or industrial environments. Breakout fiber optic cable is designed for use in applications where the fibers need to be accessed individually, such as in a patch panel. This type of cable has a central tube, similar to loose tube fiber optic cable, but the individual fibers are accessible at regular intervals along the length of the cable.
