A fiber jump line, also known as a fiber patch cable or fiber optic patch cord, is a flexible cable made of one or more optical fibers used to transmit digital signals over short distances. It is commonly used to connect two network devices such as switches, routers, or servers in a data center, LAN or WAN.
The structure of a fiber jump line consists of four main components: the connector, the fiber optic cable, the jacket, and the strain relief boot.
Connector:
The connector is the component at the end of the fiber jump line that attaches to the network device. It is made up of a ferrule, which is a ceramic or metal sleeve that holds the fiber, and a coupling mechanism that secures the connector to the network device. The most common types of connectors used in fiber jump lines include LC, SC, ST, and MPO/MTP.
Fiber optic cable:
The fiber optic cable is the core component of the fiber jump line. It consists of one or more optical fibers, which are made of glass or plastic and transmit digital signals using light. The optical fibers are protected by a coating of high-strength, lightweight material, such as Kevlar, which provides resistance to tension and flexure.
Jacket:
The jacket is a protective outer layer that covers the fiber optic cable. It is made of a durable material such as PVC or LSZH, which protects the cable from damage and wear caused by bending, twisting, and other forms of stress. The jacket also provides environmental protection, such as resistance to moisture, heat, and cold.
Strain relief boot:
The strain relief boot is an additional layer of protection that is often added to the connector end of the fiber jump line. It is made of a soft, flexible material such as rubber, which provides a cushioning effect and reduces the risk of damage to the connector due to bending, pulling, or other types of strain.
In summary, a fiber jump line is made up of a connector, fiber optic cable, jacket, and strain relief boot. These components work together to provide a reliable, high-speed connection between network devices, allowing for the transmission of digital signals over short distances. It is important to choose the right type of fiber jump line for your application to ensure reliable signal transmission and to maintain the integrity of your network.
