purchase of vrouters, vswitches, and other network devices is also very important.Internet cafes have diversified network application types and have high requirements on network bandwidth, transmission quality, and network performance. network applications must integrate advanced, multi-service, scalability, and stability, it not only meets customers' needs for simultaneous transmission of voice, video, and data over a broadband network, but also supports a variety of new business data processi

The optical fiber access technology is worth learning a lot. Here we mainly introduce the features of China's FTTH target market, this section describes the high investment in FTTH Network Construction from a development perspective, and avoids blindly requiring full-service access. So far, fiber-to-household fiber-to-home-FTTH has been widely used in Japan and t

When you need to connect a newly purchased Soundbar or AV receiver to a device in your home, you are bound to have two main audio lines connected: HDMI and fiber. Perhaps for most users, HDMI is actually the simplest choice, but if you understand the characteristics of the fiber audio cable, it might not be easy to choose the HDMI way to connect. In general, both HDMI and

Principle and sensing process of Distributed Optical Fiber Temperature Measuring System The Distributed Optical Fiber Temperature measuring system can be divided into three types based on the backward scattering principle: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering D

The cabling system is widely used in multi-mode Z optical fiber due to a small number of trunk lines connected to the floor. in the horizontal direction, there is no suitable medium that can provide sufficient bandwidth, it also has the advantages of easy installation, low cost, and strong anti-interference ability. The new plastic optical fiber (POF) as the transmission media of the all optical

"Netizen asks a question": have been not clear exactly what difference does photoelectric converter, fiber transceiver, light cat, light module have? "Answer": Optical module is inserted in the router or switch, can not be used independently, belong to other devices part. and netizens mentioned (photoelectric converter, optical transceiver, light cat, optical module) A few things are basically one thing, and the name is not standardized, more ambigu

1 Introduction Nowadays, delay lines have been widely used in signal processing, radar, electronic countermeasure, and other fields. For example, the Unit delay device required for signal processing is a kind of memory, and the dynamic target display (MIT) there must be a delay line-another kind of memory. In electronic confrontation, the signal must be stored for a certain period of time before processing. For example, the receiver's radar signal must be delayed for a certain period of time be

Optical Fiber Network Fault Test Equipment Analysis In recent years, as people have higher and higher requirements on the rate of broadband, because the performance of optical fiber is better than that of copper cable, it has been widely used in the backbone construction of broadband projects. At the same time, due to the increasing coverage of optical fibers, fiber
