ITU-T L.155/L.83 (07/2010)

تقنية خفيفة الوطأة لحفر الخنادق لشبكات توصيل الألياف إلى أي مطراف (FTTx)

مع تصغير البنية التحتية للاتصالات، أي تصغير الأنفاق وتصغير الكبلات، أصبح بالإمكان استعمال تقنية حفر منخفضة الأثر للقيام بجميع خطوات إنشاء الشبكة في يوم واحد، بأسلوب أقل توسعاً من منظوري الوقت والمساحة وفي موقع بناء أصغر من تكنولوجيا الحفر السابقة. وتشرح التوصية ITU-T L.83 تقنية الحفر هذه التي تسمح بالتركيب السهل للكبلات البصرية تحت الأرض في خنادق ضيقة ولكبلات صغيرة في أنفاق أو أنفاق صغيرة أو دفنها مباشرة. ويسمح هذا النوع من الخنادق الصغيرة باستخدام آلات ذات أبعاد مخفضة في الطرق الضيقة، الموجودة في المدن عادة، وإنتاج كمية أقل من مخلفات الحفر ومن ثم ينبغي استعمالها في المناطق الحضرية. وتتسم هذه التقنية بصورة أساسية بإمكانية عمل آلة التفريغ وآلة الحفر في آن واحد، وهو ما يسمح بإمكانية الحفر والردم في موقع العمل في نفس اليوم.
