First, ADSS cable characteristics 1, ADSS cable hanging on the inside of the cable, can be set up without power;2, light weight, small cable, small load on the tower;3, large span, up to 1200 metres;4, the use of polyethylene sheath, with good resistance to electrical corrosion;5, non-metallic struc

Hollow splicing refers to a construction technique in which only the fibre core of the branch cable is spliced and the other fibres are straight through (not disconnected) in the branch splice of the cable when the number of fibre cores in the main route remains unchanged. As the cable hollowing onl

Increasing the number of optical fiber cores is the most efficient way to increase the transmission capacity of fiber optic cable lines. However, it will also bring a series of problems such as fiber diameter is too thick, fiber can not be identified, repair difficulties and so on. This article will

1, the difference between switches and routers?From the application:Switch and router in the use of the biggest difference is no more than the router can be achieved within the dial-up Internet, and then through the sharing of multiple computers at the same time to access the Internet, while the swi

Definition of Silicon Optical Module and General Optical ModuleOrdinary optical modules are usually coupled with high-speed circuit silicon chips, III-V semiconductor chips, optical components, and other devices.Its development path follows Moore's law, in essence, belongs to the "electrical interco

First, the material is differentAluminium clad steel is steel as the core material, outsourced with aluminium or aluminium alloy, belongs to a kind of outsourced aluminium products. Steel core aluminium stranded wire is made of multi-stranded aluminium and steel core stranded into an alloy cable.Sec

This is a technology that collects sunlight through outdoor lenses and then uses optical fibres to channel it into the room for lighting. It mainly consists of an outdoor light collection system, a light guide system and an indoor light projection system. Outdoor sunlight is collected by a light col

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
