Digital communication traditionally relies on binary codes, where copper wires transmit signals as electrical pulses: a pulse means “1” and no pulse means “0.”<\/p>\n

The growing demand for faster and more efficient data transmission in the modern world led to a breakthrough in 1965. Charles Kao and George Hockham discovered a better way to transmit signals using light through glass fiber.<\/p>\n

This glass structure, known as the optical core, is used to carry light pulses generated by lasers. The light reflects off the edges of the optical core as it travels.<\/p>\n

Therefore, the diameter of the core determines the distance the signal can travel.<\/p>\n

Fiber optic connections use light pulses instead of electrical pulses from copper wires; light on means “1,” light off means “0.” This type of connection has several advantages:<\/p>\n

    \n
  • Faster data transmission over longer distances<\/li>\n
  • Higher bandwidth capacity to carry more data simultaneously<\/li>\n
  • Immunity to electromagnetic interference, offering greater reliability<\/li>\n
  • Ease of installation and maintenance with lightweight cables<\/li>\n<\/ul>\n

    There are two main types of fiber optic connections:<\/p>\n

      \n
    1. Single-mode fiber (SMF)<\/strong>, designed for long-distance communication with a narrow optical core, uses a single light path or mode.<\/li>\n
    2. Multi-mode fiber (MMF)<\/strong>, with a wider optical core, is used for shorter distances and can carry multiple light modes simultaneously.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>

      One of the obstacles to this technology is the presence of dust or other particles in harsh outdoor environments, which can cause light loss, reduced bandwidth, and intermittent transmission.<\/p>\n

      Expanded beams solve this problem by using two lenses to avoid physical contact. The first lens at the fiber’s tip expands and collimates the light, making it parallel.<\/p>\n

      The second lens refocuses the light onto the receiving fiber, restoring the original beam size. This is ensured by lenses with a fixed or variable refractive index, which guarantees the light remains collimated.<\/p>\n

      The fact that the lenses do not make contact also helps maintain data transmission in case of exposure to dirt.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
