optical fiber

The characteristics of optical fiber are: 1. Long transmission distance, the optical fiber connection distance can reach 70 kilometers; 2. Fast transmission speed, optical fiber access can provide high-speed bandwidth such as 100Mbps, 200Mbps; 3. Low loss, optical fiber medium The manufacturing purity of optical fiber is extremely high, so the loss of optical fiber is extremely low, which can reduce the number of relay stations in communication lines and improve communication quality; 4. Strong anti-interference ability. Optical fiber is a non-metallic dielectric material. Using optical fiber as a conductive medium is not affected by Electromagnetic interference.

Optical fiber introduction

Optical fiber is The signal is transmitted in the form of light pulses, and glass or plexiglass is used as the network transmission medium. It consists of fiber core, cladding and protective sheath. Optical fibers can be divided into single-mode optical fibers and multi-mode optical fibers.

Single-mode optical fiber only provides one optical path and is complex to process, but it has greater communication capacity and longer transmission distance. Multimode fiber uses multiple optical paths to transmit the same signal and controls the transmission speed through the refraction of light.

Optical fibers are generally used for the transmission of communication networks. During the transmission process, different types of optical fibers are selected according to different environments and transmission requirements. The optical fibers used in computer networks include the following categories:

  • 8.3pm core/125pm shell, single-mode optical cable;

  • 62.5um core /125um shell, multi-mode optical cable;

  • 5OPm core/125pm shell, multi-mode optical cable;

  • loopm core/140pm shell, multi-mode fiber optic cable.

Characteristics of optical fiber:

1. Long transmission distance: the optical fiber connection distance can reach 70 kilometers;

2. Fast transmission speed: Optical fiber access can provide high-speed bandwidth such as 100Mbps and 200Mbps;

3. Low loss: The manufacturing purity of optical fiber media is extremely high, so the loss of optical fiber is extremely low, which can reduce the number of relay stations in communication lines. Quantity, improves the quality of communication;

4. Strong anti-interference ability: Optical fiber is a non-metallic dielectric material. It uses optical fiber as a conductive medium and is not subject to electromagnetic interference.

Summary

Optical fiber technology is a modern communication technology. Its advantages include long transmission distance, fast transmission speed, low loss, and strong anti-interference ability. First of all, the connection distance of optical fiber can reach 70 kilometers, and the technology has a wider coverage and can meet the communication needs of different regions. Secondly, optical fiber can provide high-speed bandwidth such as 100Mbps and 200Mbps, with fast transmission speed, which can meet the transmission needs of large amounts of data and improve data transmission efficiency. In addition, the manufacturing purity of the optical fiber medium is extremely high, so the loss of the optical fiber is extremely low, which can effectively reduce signal loss and bit error rate. Finally, optical fiber is a non-metallic dielectric material that is not subject to electromagnetic interference and can provide strong immunity to interference, making data transmission more reliable and stable. Therefore, optical fiber technology has been widely used in today's communications and has become one of the important forces promoting the development of modern communications technology.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
