exchange speed, reduce costs and improve reliability. In an ideal all-optical network, all functions of signal exchange, route selection, transmission and recovery are all in the form of light. At present, all optical network is not the whole network optical, but refers to the optical information flow in the transmis
FFMPEG (ii)-Universal multiplexer One: Technical points As mentioned in the previous article, the reuse structure of the MP4 type differs from other types, such as mp4,mov,flv, where the H264 data does not contain descriptive information such as SPS,PPS, to reduce overhead, The same is true for AAC data, which requires converting the previous 7-byte Adts header to a two-byte frame length. FFmpeg provides something called the filter filters to do this.

At present, Wavelength division multiplexing (WDM) system is developed, which is about 10. Recently, a kind of 1.2tb/s wavelength division switching system has been developed, it adopts the wavelength division multiplexing number of 128, the maximum terminal number is 2048, and the
1. Preface A cylindrical media waveguide consists of three parts: Core, package layer, and coating layer. Generally, the diameter of the core of a single-mode or multi-mode optical fiber is 5 ~ 15 μm and 40 ~ 100 μm, with a diameter of about 125 ~ 600 μm. The processed optical fiber end face is ideally a smooth plane. However, in reality, the processing of the optical
After reviewing the network development process, we will all feel that the network is evolving with each passing day, and network applications have been updated and upgraded almost every several years, the continuous development of network applications puts forward higher bandwidth and other related performance requirements to people. With the popularization and application of gigabit and 10-Gigabit networks, in our traditional cabling system, currently, copper cable systems can only be used for
Most of the integrated cable systems are installed using traditional optical fiber systems. In this case, appropriate Optical Fiber installation should be carried out using the discussed design methods. The system has proved to be feasible, reliable, stable, mature, and excellent through numerous successful cases. Recently, another installation technology called "air blow
After a long period of development, many users are familiar with the optical fiber connection technology in the optical fiber access network. Here I will share my personal understanding and discuss with you. The development of optical fiber connection technology (such as splicing technology to replace the crimping technology) makes the application of
The optical fiber access network has a lot to learn about. Here we mainly introduce the application specifications of optical fiber cabling in the optical fiber access network. As fiber access networks have been widely used in China only in recent years, telecom operators generally feel that they lack experience in building fiber access networks. The gradual impl
