Optical fiber cables have several advantages

The conversion of conductors to fiber optics marks the transition period from a communication transmission system to a high-speed, long-distance, reliable, and high signal integrity system. Fiber optic technology broke new ground in communication speed and introduced the fastest digital data transport system.

The main advantages of fiber optics are that they help modern communication systems to minimize signal degradation and electromagnetic interference. Let's take a closer look at these fibers and what makes them so beneficial.

Fiber Optic Communication

In fiber optic communication, data is transmitted as a single wavelength light source. Electrical signals converted into this light source can travel long distances with more power and less distortion. Fiber optic data density is much higher than traditional conductor transmission and contains more data packets.

A fiber optic communication system converts incoming electrical signals into light at the transmitter end. Data can only be stored in a digital format with this type of system. Analog data signals are converted into digital signals using an encoder or converter circuit. The light source turns on and off quickly upon receiving the digital signal and carries the same data as the input electrical signals.

At the receiving end, light detectors are used to receive light signals from the optical fiber. Photodetectors and electronic amplifiers typically make up the receiver. Silicon and germanium diodes are typical photodetectors in fiber optic communications. The digital signals from the amplifiers are routed directly to the destination. If the target destination requires analog signals, decoders are used for conversion.

The benefits of fiber optic communication

Internet communication, cable television, and television broadcasting systems benefit from the use of fiber optic technologies in signal transmission. The benefits of fiber optic communications include:

  • High-speed data transmission
  • Data security
  • Data reliability

Fiber optic cables

The most important element of fiber optic communication is fiber optics. These are transparent glass fibers that propagate light waves between the transmitting and receiving ends. A fiber optic cable can be classified into three types:

  • Single-Mode Fiber Optic Cables - Single-mode fiber optic cables pass only one wavelength. Fiber optic cables of this type are used in applications requiring low attenuation and dispersion.
  • Multimode fiber optic cables - In multimode fiber optic cables, multiple lanes allow transmissions at multiple wavelengths. The core diameter of multimode optical fibers is larger than that of single-mode fiber optic cables. The two types of multimode fibers are step-index multimode fibers and gradient-index multimode fibers. Communication over short distances is typically conducted using multimode fiber optic cables.
  • Plastic Glass Fiber - Plastic Glass Fibers are massive size core pitch index fibers made of glass. These cables are suitable for coupling light from several sources and their connection requires less precision. Plastic glass fibers are long-lasting and are mainly used in short-distance and low-speed communication links.

The advantages of fiber optic cables

  • Fiber optic cables have higher bandwidth than cables with copper conductors. Single-mode fiber optic cables are the best, considering the bandwidth.
  • Data security is an inherent property of fiber optic cables.
  • The electromagnetic immunity of fiber optic cables is excellent. Transmission of signals by fiber optics is uninterrupted, and there is no crosstalk or degradation in performance. This advantage of fiber optic cables makes them suitable for electronic and industrial environments.
  • The high transmission capacity of fiber optic cables is equivalent to that of one hundred conductive transmission cables put together.
  • Fiber optic cables are more durable, cheaper, and lighter than traditional copper cables.

The many advantages of fiber optic cables make it the most widely used communication and signal transmission technology. Litech offers software to support the electronics/photonics design automation framework, which is useful for fiber optic applications.
