Will quantum optic network come true soon?
Scientists have moved quantum optic networks a step closer to reality. The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more quickly and securely than an electrical network. A team of researchers at the U.S. Department of Energy’s (DOE) Argonne […]
انواع کابل فیبر نوري بر اساس ویژگی هاي محیطی Fiber Optic Cable
کابلهاي فیبر نوري بسته به محیطی که باید در آن نصب شوند در انواع کاملا متفاوتی تولید مـی شـوند. هـر چند که ماهیت تارهاي فیبر نوري درون آنها یا از نوع MMF یا SMF با پارامترهاي کمابیش مشابه اسـت. تمام انواع مختلف کابلهاي فیبر نوري را می توان در دو رده کلی زیر دسته بندي کرد: 1 […]
Fiber Considerations for 100 Gig – 2
Network Design and Layout As in previous Ethernet standards, 40 Gb/s and 100 Gb/s define several different Physical layer (PHY) implementations for transmitting information over various distances and media types. These media types include multimode and singlemode optical fiber cabling and some form of copper cabling. Additionally, various transceiver types are defined, distinguished by which […]
