1 Core Fiber Optic Cable Single Mode Fiber Drop Cable High Efficiency

Product Specification

• Core: The core is the central part of the fiber - optic cable. It is the light - carrying component and is usually made of high - purity silica glass. The diameter of the core can vary, but common diameters range from 8.3 to 100 micrometers. The refractive index of the core is higher than that of the surrounding material, which helps to keep the light signal within the core through a principle called total internal reflection.
• Cladding: Surrounding the core is the cladding. It is also made of glass or plastic, with a lower refractive index than the core. The cladding's main function is to prevent the light from escaping out of the core and to protect the core from external factors such as scratches and moisture. The typical thickness of the cladding is around 125 micrometers in total diameter when combined with the core.
• Buffer Coating: Outside the cladding, there is a buffer coating. This layer provides mechanical protection to the fiber and can be made of acrylate or other polymers. It helps to absorb shocks and prevent the fiber from breaking during installation or use.
• Strength Members: In addition to the fiber - optic strands, cables often contain strength members. These can be made of materials like aramid yarns (such as Kevlar) or steel wires. The strength members provide tensile strength to the cable, allowing it to be pulled through conduits and ducts during installation without breaking the delicate optical fibers.
• Outer Jacket: The outermost layer is the outer jacket. It is usually made of a durable plastic material such as polyethylene or polyvinyl chloride (PVC). The outer jacket protects the cable from environmental factors such as sunlight, water, and abrasion. It also provides identification markings that can indicate the type of cable, its intended use, and other relevant information.

• High Bandwidth: Fiber - optic cables have an extremely high bandwidth, which means they can carry a large amount of data. They can support data rates of up to terabits per second (Tbps), making them ideal for applications such as high - speed internet access, long - distance telecommunication, and data center interconnections.
• Low Signal Loss: Compared to traditional copper cables, fiber - optic cables have much lower signal loss. The light signals can travel long distances (up to hundreds of kilometers) without significant degradation. Signal boosters, known as repeaters, can be used at intervals to further extend the transmission distance.
• Immunity to Electromagnetic Interference: Since fiber - optic cables transmit light signals rather than electrical signals, they are immune to electromagnetic interference (EMI). This makes them suitable for use in environments with high levels of electrical noise, such as near power lines, industrial machinery, or radio transmitters.
• Security: The light signals in fiber - optic cables are difficult to tap without detection. Any attempt to access the data being transmitted through the cable by physically splicing or tapping the fiber will cause a significant disruption to the light signal, which can be easily detected. This provides a high level of security for sensitive data transmission.

• Cost: The initial cost of installing fiber - optic cables is relatively high. The cables themselves are more expensive than copper cables, and the installation requires specialized equipment and trained technicians. Additionally, the cost of the transmitters and receivers used with fiber - optic systems can also be significant.
• Fragility: Optical fibers are relatively fragile and can be easily damaged during installation or maintenance. They require careful handling to avoid breaking or scratching the fiber, which could lead to signal loss or complete failure of the cable.
• Limited Bending Radius: Fiber - optic cables have a limited bending radius. If the cable is bent too sharply, the light signals may leak out of the core, resulting in signal loss. This requires careful routing of the cables to ensure that they are not bent beyond their specified tolerance.

• Telecommunications: Fiber - optic cables form the backbone of the global telecommunications network. They are used for long - distance telephone calls, internet access, and data transmission between different cities and countries. Mobile network operators also use fiber - optic cables to connect cell towers to the core network, improving the speed and reliability of mobile communications.
• Cable Television: Fiber - optic cables are increasingly being used in cable television systems to provide high - definition (HD) and ultra - high - definition (UHD) video content. They offer a higher bandwidth than traditional coaxial cables, allowing for more channels and better picture quality.
• Data Centers: In data centers, fiber - optic cables are used to connect servers, storage devices, and networking equipment. The high - speed and low - latency characteristics of fiber - optic communication are essential for efficient data processing and storage.
• Medical Imaging: Some medical imaging equipment, such as endoscopes and optical coherence tomography (OCT) devices, use fiber - optic cables to transmit light for internal imaging of the body. The small size and flexibility of the fibers allow for minimally invasive procedures.
