Koja je razlika između optičkih kablova u zatvorenom i optičkih kablova na otvorenom

1. Prema različitim prirodnim okruženjima, optički kablovi se dijele na unutarnje i vanjske. Središte optičkog kabla je optičko vlakno, a centar optičkog vlakna je obično staklena jezgra. Jezgra je okružena staklenom ljuskom s nižim indeksom loma od jezgre, pa optički signal koji ulazi u jezgru reflektira interfejs obloge, omogućavajući svjetlosti da prolazi kroz jezgro. Budući da je samo optičko vlakno vrlo krhko i ne može se izravno primijeniti na ožičenje, snop optičkih vlakana obično se isporučuje sa vanjskim zaštitnim slojem i žicom sa srednjim zatezanjem. Ovo je takozvani optički kabel, which usually contains one or more optical fibers.

2. The characteristics of indoor optical cable: The tensile strength of indoor optical cable is small, the protective layer is poor, but it is relatively lighter and more economical. Indoor optical cable is mainly suitable for horizontal wiring subsystem and vertical backbone subsystem. Outdoor fiber optic cables have higher tensile strength, a thicker protective layer, i obično su oklopni. Outdoor optical cables are mostly used for subsystems of building complexes, and can be used for outdoor direct burial, pipeline, overhead, and underwater laying.

3. Features of outdoor optical cables: mainly composed of optical fiber (thin glass filaments such as hair), plastic protective sleeves and plastic sheaths. There are no metals such as gold, silver, copper and aluminum in the optical cable, and generally have no recycling value. Outdoor optical cables have higher tensile strength, a thicker protective layer, i obično su oklopni (to je, obloženi metalom). Vanjski optički kablovi uglavnom su pogodni za međusobno povezivanje zgrada i udaljenih mreža.

4. Outdoor optical cable is a communication line that realizes optical signal transmission. The cable core is composed of a certain number of optical fibers in a certain way, and is covered with a sheath, and some are also covered with an outer sheath. An indoor optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and are covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission.

5. Indoor optical cable: yellow single-mode optical cable, orange multi-mode optical cable, aqua-green 10G optical cable. Outdoor optical cable: Generally, it has a black outer sheath with a relatively hard texture. Also to consider the effects of ultraviolet radiation and corrosion resistance
