Copper vs Fiber They are two major types of cables used in networking‚ copper and fiber. Each cable are used in different application regarding to its usage. They also have different strengths cause of the material they are made of. Copper is the most common out of the two cables. Not as powerful as Fiber‚ but are ideal for buildings up to 100m. Fiber is mostly used for longer distances that copper can’t reach. For example‚ Fiber is ideal for high-rise buildings. Both cables do have their weakness

decades‚ through their JIT systems‚ world class manufacturers have dominated their competitors not only in the areas of price‚ quality‚ and manufacturing speed but also in new product development speed and quick commercialization of new technologies (Bebb‚ 1989; Dumaine‚ 1989a & b; Blackburn‚ 1991; Clark and Fujimoto‚ 1991; Ulrich and Eppinger‚ 2000). To understand the relationships between JIT manufacturing and simultaneous NPD process‚ let’s briefly review the principles of JIT systems. Just-in-Time

When trying to decide between copper and fiber cabling‚ there are several things to think about for which one best will fit your needs. A few things you will need to take into consideration when making your decision are what do you need your cable to be capable of‚ how far do you need your cable to run from point to point‚ what is your budget‚ and always think about the future with room to expand your business. Both copper and fiber cabling have pros and cons. Copper cabling has been around ever

Copper was the first metal that is used by humans as weapons and tools. It is shinny and has a reddish brown color. It’s application toward humans has really changed the way we live. Copper is an excellent conductor of electricity‚ which is often used as electrical wires or cables in generators‚ motors and electric products. In addition‚ it is also an outstanding conductor of heat‚ which is used in radiators and heating systems. Since it does not react with water and corrode easily‚ it is widely

chemical element copper‚ with Atomic Number 29‚ has been extensively used for thousands of years because of several primary properties that have dictated its use throughout history. Among them we can count durability‚ strength and‚ as a semi-noble metal‚ good resistance to corrosion. With a hardness of 3 on the Mohs scale‚ pure copper is relatively soft and malleable‚ which makes it an easy metal to work with. Analyses of artefacts from lithic civilizations have shown that native copper had not only

Graphene replaced with copper Graphene nanoribbons have a current-carrying capacity two orders of magnitude higher than copper Recent research into the properties of graphene nanoribbons provides two new reasons for using the material for interconnects in future computer chips. In widths as narrow as 16 nm‚ graphene has a current-carrying capacity approximately a thousand times greater than copper while providing improved thermal conductivity. The current-carrying and heat-transfer measurements
