| Критерии технического обслуживания волоконно-оптических кабелей для испытания волокна в рабочем режиме в сетях доступа |
В эпоху широкого использования технологии FTTx (оптоволокно до точки Х) следует обеспечивать эффективное и рациональное техническое обслуживание оптических кабельных сетей. Для построения высоконадежной оптической кабельной сети, способной передавать сигналы WDM (уплотнение по длинам волн) с большой спектральной полосой пропускания, необходимо установить критерии технического обслуживания для проведения эксплуатационных испытаний оптоволоконных линий, не создавая при этом помех сигналам оптической связи в сети доступа. Данная Рекомендация рассматривает важные соображения, касающиеся требований к полосе частот технического обслуживания и к фильтрации диагностических сигналов для технического обслуживания при проведении эксплуатационных испытаний оптоволоконных линий, без причинения помех сигналам оптической связи в сетях доступа. |
