The working characteristics of optical fiber cables are mainly reflected in the following aspects:
1. High-speed transmission capability
Fiber optic cables use optical signals for data transmission, and their transmission speed is much faster than that of traditional copper cables, close to the speed of light. This high-speed transmission capability makes fiber optic cables a key component in modern communications networks, especially the Internet and wide area networks.
2. Long-distance transmission capability
Fiber optic cables have very small signal attenuation and are able to maintain signal integrity over extremely long distances without the need for frequent use of signal amplifiers or Repeaters. This makes fiber optic cables play an important role in cross-city, cross-country and even trans-ocean communications.
3. Large-capacity transmission
Fiber optic cables are capable of transmitting multiple optical signals simultaneously, and each optical signal can carry a large amount of data. This large-capacity transmission capability meets the needs of modern communication networks for high bandwidth and low latency.
4. Strong anti-interference ability
Fiber optic cables are not affected by electromagnetic interference and can work normally in harsh electromagnetic environments. This characteristic makes fiber optic cable have a wide application prospect in military, aerospace and other fields.
5. Good confidentiality
The optical signal is difficult to be eavesdropped or tampered with when it is transmitted in the optical fiber, so the optical fiber cable has better confidentiality. This is especially important for communication situations that require a high degree of confidentiality.
6. Low loss
The loss of fiber optic cables is very low, especially the attenuation of single-mode fiber at specific wavelengths is very small. For example, a single-mode fiber using 9/125μm has only about 0.3dB/km of attenuation at a wavelength of 1550nm. This low loss characteristic makes fiber optic cables more advantageous for long distance transmission.
7. Wide frequency band
The frequency band width of fiber optic cables can reach more than several GHz, far exceeding that of traditional copper cables. This high frequency width characteristic enables the fiber optic cable to simultaneously transmit a variety of signals (such as voice, image, data, etc.), improving the overall efficiency of the communication system.
8. Material characteristics
Fiber optic cables are made of non-conductive materials such as glass or plastic, so they are lightning-resistant and corrosion-resistant. At the same time, the optical fiber cable is light in weight and small in size, which is easy to install and maintain.
9. Precise connection technology
The connection of optical fiber cable is a carefully operated work, requiring that the contact surface of the connection is smooth and smooth, and the contact center of the optical fiber at both ends is fully aligned. This precise connection technology ensures that the optical signal does not suffer significant attenuation and distortion during transmission.
10. Multiple types to suit different needs
Fiber optic cables are divided into single-mode fiber and multi-mode fiber and other types, each type has its own unique characteristics and application scenarios. For example, single-mode fiber is suitable for long-distance, high-bandwidth communication needs; Multimode fiber is suitable for short-distance, low-cost communication needs. This diverse selection of types enables fiber optic cables to meet the communication needs of different fields and scenarios.
In summary, optical fiber cable with its high-speed transmission capacity, long-distance transmission capacity, large capacity transmission, anti-interference ability, good confidentiality, low loss, wide frequency band and material characteristics and other advantages, in the modern communication network plays an increasingly important role.
