光纖以光脈衝形式傳輸信號,材質以玻璃或有機玻璃為主,由纖維芯、包層和保護套組成,因此不受外界電磁信號干擾,信號的衰減的速度慢,傳輸距離也比網線要遠得多,特別適用電磁環境惡劣地方。

根據光信號發生的方式不同,光纖可分為單模光纖和多模光纖。

單模光纖傳遞數據質量高,傳輸距離長,常用於連結辦公樓之間或地理分散更廣的網絡;而多模光纖則用於同一辦公樓或距離相對較近的區域。

——————

The optical fiber transmits signals in the form of light pulses. The material is mainly glass or plexiglass. It is composed of a fiber core, a cladding, and a protective sleeve. Therefore, it is not affected by external electromagnetic signals. The signal decays slowly and the transmission distance is longer than the network cable. Much farther, especially suitable for harsh electromagnetic environment.

Optical fibers can be divided into single-mode fibers and multi-mode fibers according to the way in which optical signals occur.

Single-mode optical fiber has high data transmission quality and long transmission distance. It is often used to connect office buildings or geographically dispersed networks. Multi-mode optical fiber is used in the same office building or relatively close area.
