ITU-T L.71 (01/2008)

تصميم وبناء وتركيب الشبكات النحاسية من أجل النفاذ عريض النطاق بما في ذلك الشبكات النحاسية الموصولة بشبكات الألياف البصرية

تتناول التوصية ITU-T L.71 تصميم كبلات الشبكة وبناءها وتركيبها للحصول على النفاذ عريض النطاق. ولتصميم شبكة من الكبلات المعدنية من أجل النفاذ عريض النطاق، يمكن النظر أولاً في عدد الخطوط التي ستُقدم، ونوع نظام النفاذ الذي سيُركَّب، xDSL مثلاً، وتوفر الشبكات النحاسية. وتشمل هذه التوصية عملية تصميم وأمثلة عن البناء.
