| كبلات الألياف البصرية لأغراض التوصيلات الفرعية |
تصف التوصية ITU-T L.87 خصائص كبلات الألياف البصرية وبنيتها وطرائق اختبارها من أجل تطبيقات التفريع. وتستخدم كبلات تفريع الألياف البصرية لتوصيل العملاء بشبكات النفاذ البصرية. وقد تقع نقاط النفاذ داخل المباني أو خارجها حسب تشكيلة شبكة النفاذ. وعندما تكون نقاط النفاذ خارج المباني، فإن كبلات تفريع الألياف البصرية تكون عرضة للبيئة الداخلية والخارجية على السواء، ومن ثم ينبغي تصميم كبلات تفريع الألياف البصرية في هذه الحالة بحيث تلائم البيئتين. كما تشرح هذه التوصية الخصائص التي يحتاج إليها كبل من الألياف البصرية لكي يعمل بشكل جيد. وعلاوة على ذلك، يرد وصف لطريقة لتحديد ما إذا كان الكبل يتمتع بالخصائص اللازمة أم لا. وقد تختلف الشروط المطلوبة طبقاً لبيئة التركيب؛ ويجب الاتفاق على الشروط التفصيلية للاختبار بين المستعمل وجهة التصنيع أياً كانت البيئة التي سيُستخدم فيها الكبل (في حالة تطبيق إنشاءات صغيرة أثناء وبعد التركيب، على وجه الخصوص). |
