Fiber Communication Features

Huge Communication Capacity

Theoretically, a single fiber can transmit 10 billion voice channels simultaneously.

Current experiments have successfully transmitted 500,000 voice channels at the same time, which is thousands of times higher than traditional coaxial cables and microwaves.

Long Relay Distance

Optical fiber has a very low attenuation coefficient.

With suitable optical transmission, receiving equipment, optical amplifiers, forward error correction, and RZ coding modulation technology, its relay distance can reach thousands of kilometers.

In contrast, traditional cables can only transmit up to 1.5km, and microwaves up to 50km, making optical fiber far superior.

Good Confidentiality

Optical fiber offers excellent confidentiality for secure communications.

Strong Adaptability

It is resistant to strong external electromagnetic interference and corrosion.

Small Size and Light Weight

Optical fibers are compact and lightweight, making them easy to handle and install.

Abundant Raw Materials and Low Prices

The primary material for optical fibers is high-purity silica glass (SiO2), which is abundant and inexpensive.

Fiber Optic Concept

Optical fiber is made of glass or plastic and functions as a light-conducting tool.

Mainly used for communications, silica-based optical fibers are predominant, composed of high-purity silica glass.

Fiber Construction

Optical fibers are cylindrical and consist of:

  • Core: The central part made of high-purity silica doped with a small amount of dopant.
  • Cladding: Surrounds the core and is also made of high-purity silica with minimal dopants.
  • Coating: The outermost layer, made of materials like acrylic, silicone rubber, and nylon.

How Fiber Optics Work

Optical fibers transmit signals using the principle of total reflection.

When light passes from a denser medium to a less dense medium, the refraction angle is greater than the incident angle, allowing the light to be totally reflected within the fiber.

Fiber Dispersion

Causes of Fiber Dispersion

Optical signals in fibers consist of various components that travel at different speeds, causing time delays and signal distortion, known as fiber dispersion. This can result in pulse broadening.

Effects of Fiber Dispersion

Fiber dispersion distorts and broadens transmitted signal pulses, causing intersymbol interference.

This requires increasing the inter-symbol interval, reducing the transmission rate, thus limiting the fiber system’s communication capacity and transmission distance.

Classification of Fiber Dispersion

Fiber dispersion can be classified into modal dispersion, material dispersion, waveguide dispersion, and polarization dispersion.

Fibconet PLC Splitter Features

  • Uniform Light Distribution: Optical signals are evenly distributed to multiple end users, with up to 64 channels.
  • Compact Structure: Small size, easily installable in various transfer boxes.
  • Cost Efficiency: More split channels enhance the cost advantage, making it ideal for passive optical networks.
