  1. Huge communication capacity
    Theoretically, a single fiber can transmit 10 billion voice channels at the same time. At present, the experiment of transmitting 500,000 voice channels at the same time has been successful, which is thousands or even hundreds of thousands times higher than traditional coaxial cables and microwaves.
  2. Long relay distance
    Optical fiber has a very low attenuation coefficient, and with appropriate optical transmission, optical receiving equipment, optical amplifier, forward error correction and RZ coding modulation technology, etc., can make its relay distance reach more than thousands of kilometers, while traditional cables can only Transmission 1.5km, microwave 50km, can’t compare with it at all.
  3. Good confidentiality
  4. Strong adaptability: it has the advantages of not being afraid of the interference of strong external electromagnetic fields, corrosion resistance, etc.
  5. Small size and light weight
  6. Abundant sources of raw materials and low prices. PLC fiber splitter PLC fiber splitter

Fiber optic concept
The full name of the optical fiber is called optical fiber, and the English name is OPTIC FIBER. It is a fiber made of glass or plastic that acts as a light-conducting tool. The main use of fiber optics is for communications. At present, the optical fibers used in communication are mainly silica-based optical fibers, and the main component is high-purity silica glass, namely silicon dioxide (SiO2).

Fiber Construction
The optical fiber is cylindrical and mainly consists of a core, a cladding, and a coating.
Core: Located in the center of the fiber, it is composed of high-purity silica, doped with a very small amount of dopant.
Cladding: Located around the core, it is also composed of high-purity silica with very small amounts of dopants.
Coating: The outermost layer of an optical fiber, consisting of acrylic, silicone rubber, and nylon.

How Fiber Optics Work
The principle of total reflection: if the light beam is directed from the optically denser medium to the optically sparser medium, the refraction angle is greater than the incident angle. Phenomenon. Optical fibers use this total reflection to transmit optical signals. PLC fiber splitter PLC fiber splitter

Fiber Dispersion
Causes of Fiber Dispersion
In an optical fiber, an optical signal is composed of many different components. Due to the different propagation velocities of each frequency component or each mode component of the signal, after a certain distance through the optical fiber, a time delay difference occurs between the different components, causing the transmission signal waveform. Distortion, pulse broadening, a phenomenon called fiber dispersion.
Effects of Fiber Dispersion
The existence of fiber dispersion distorts and broadens the transmitted signal pulse, resulting in intersymbol interference. In order to ensure the communication quality, the inter-symbol interval must be increased, that is, the transmission rate of the signal must be reduced, which limits the communication capacity and transmission distance of the optical fiber system.
Classification of Fiber Dispersion
According to the causes of dispersion, fiber dispersion can be divided into modal dispersion, material dispersion, waveguide dispersion and polarization dispersion. PLC fiber splitter PLC fiber splitter
