The difference between single-mode armored fiber and ordinary single-mode fiber

　　There are significant differences between single-mode armored fiber and ordinary single-mode fiber in several aspects. The following is a detailed analysis of the differences between the two:

　　First, structural differences

　　Single-mode armored fiber: A solid layer of metal or other materials (such as fiber yarn, glass yarn, polyethylene, etc.) is wrapped around the outside of the fiber. This layer of armor not only provides additional physical protection for the fiber, but also enhances the tensile, compressive, and impact resistance of the fiber. In addition, armored fibers may also contain structures such as sheaths, aramid, and light steel pipes to further protect the fiber.

　　Ordinary single-mode fiber: without such armor protection, its structure is relatively simple, mainly composed of optical fiber core, cladding, coating and other parts.

　　Second, performance characteristics

　　Single-mode armored fiber:

　　Due to the existence of the armored layer, the armored fiber has higher mechanical strength, wear resistance and scratch resistance, waterproof and moisture resistance, and anti-rodent and corrosion resistance. These characteristics make the armored fiber more durable and stable in harsh environments (such as outdoor, construction sites, roads, etc.).

　　Single-mode fiber transmits a single-mode optical signal, so it can ensure the stability and consistency of the signal. Compared with multi-mode fiber, single-mode armored fiber has a longer transmission distance and stronger anti-interference ability.

　　In the signal transmission process of single-mode armored fiber, due to its special structure, it can suppress noise interference well and ensure the quality of the transmission signal.

　　The loss of single-mode armored fiber is smaller than that of multi-mode armored fiber, which means that the signal strength and consistency can be better maintained during transmission.

　　Ordinary single-mode fiber:

　　Although it also has the basic properties of optical fiber, such as wide transmission bandwidth, large communication capacity, and low transmission loss, it is relatively weak in terms of mechanical strength, wear resistance, and scratch resistance, making it more suitable for use in relatively mild environments.

　　The central core is very thin (typically 9 or 10 micrometers in diameter), allowing only one mode of light to be transmitted. Therefore, the inter-mode dispersion is small, making it suitable for long-distance communication.

　　III. Application scenarios

　　Single-mode armored fiber:

　　Due to its excellent protective properties and durability, armored optical fibers are typically used in applications that require high durability and stability, such as long-distance communication, urban underground pipelines, railway signal transmission, and power system monitoring.

　　It is suitable for use outdoors or in harsh environments to provide additional mechanical protection and prevent damage to optical fibers due to environmental factors.

　　It is widely used in the field of data communication and can support high-speed data transmission and long-distance communication. It is widely used in satellite communication, Internet access and local area network.

　　It is used in medical equipment to transmit medical images and video signals with high definition pixels. In the medical field, the transmission speed, accuracy and reliability of optical fibers are very high, and single-mode armored fibers have these advantages.

　　Used in the field of oil exploration, it can support long-distance well monitoring and data transmission. It can help oil exploration companies better understand the internal conditions of oil wells and improve exploration efficiency and safety.

　　Ordinary single-mode fiber:

　　It is more suitable for offices, data centers, or other environments with relatively little physical interference. In these environments, ordinary fiber optics can meet basic communication needs at a relatively low cost.

　　IV. Cost considerations

　　Single-mode armored fiber: Due to its complex structure and additional protective layer, the manufacturing cost of armored fiber is usually higher than that of ordinary fiber.

　　Ordinary single-mode fiber: relatively low cost, suitable for use in scenarios that do not require additional protection or durability requirements.

　　In summary, there are obvious differences between single-mode armored fiber and ordinary single-mode fiber in terms of structure, performance, application scenarios and cost. When choosing fiber, it needs to be comprehensively considered according to specific application scenarios and needs.
