1 IntroductionCommunication plastic optical fiber (hereinafter referred to as plastic optical fiber) development of the beginning of almost the same as the glass optical fiber, both from the 1960s. But from the 197x era, the development of glass optical fiber is like hanging, while the plastic optic

In order to break through the limitations of traditional solid-core quartz optical fibres, researchers have been persistent in their research and exploration. During the research process, Hollow Core Fibre (HCF), which has an air core, came into being. The structure of the hollow core fiber is relat

PDU is the closest Power distribution unit to the server in a data center and is an important part of power distribution at the end of a data center.According to different functions, we generally divide PDU into basic and intelligent type two categories, a qualified basic PDU can provide reliable an

Dome type optical cable splice closure is a device used for optical cable connection, it can protect the connection point of optical fibre and provide good protection and sealing performance. In this article, we will introduce the installation steps and usage of dome type optical cable splice box in

Earth wire, also known as lightning conductor, is used to lead the current into the earth wire; electrical leakage, the current into the earth through the earth wire. The symbol for earth wire is E (Earth) ; can be divided into power supply earth wire, circuit earth wire two. According to the curren
