FAQs
1. What are the main differences between single-mode and multi-mode fiber optic cables?
Single-mode fibers support only one light path, resulting in higher bandwidth and longer transmission distances. Multi-mode fibers support multiple light paths, offering lower costs but limited bandwidth and distance.
2. What factors influence the attenuation of a fiber optic cable?
Attenuation is influenced by the cable’s material composition, wavelength of light used, and manufacturing imperfections. Bending and external factors can also contribute to signal loss.
3. How does dispersion affect the performance of fiber optic cables?
Dispersion causes light pulses to spread over time, limiting the data transmission rate and distance. Special fiber designs and signal processing techniques mitigate this effect.
4. What types of jacket materials are commonly used in fiber optic cables?
Common jacket materials include polyvinyl chloride (PVC), low-smoke zero-halogen (LSZH), and polyethylene (PE). Each material offers different levels of durability, fire resistance, and environmental protection.
5. What are some of the key applications for fiber optic cables in China?
Fiber optic cables are extensively used in telecommunications networks, broadband internet access, data centers, and industrial automation. The rapid expansion of 5G and other high-bandwidth technologies fuels the demand for these cables.
