Технология FDDI В качестве источника света допускается использование светодиодов (LED) или лазерных диодов с длиной волны 1.3 мкм. Кроме многомодового кабеля, допускается использование более качественного одномодового кабеля (Si gle Mode Fiber, SMF) и разъемов SMF-MIC для этого кабеля. В этом случае дальность физического соединения между соседними узлами может увеличиться до 40 км - 60 км, в зависимости от качества кабеля, разъемов и соединений. Требования, определенные в спецификации SMF-PMD, для мощности на выходе передатчика и входе приемника, те же, что и для одномодового кабеля. Функция определения сигнала уровня PMD Спецификация на Fiber PMD требует от этого уровня выполнения функции Sig al De ec по определению факта наличия оптических сигналов на входе физического соединения станции. Этот сигнал передается на уровень PHY, где используется функцией определения статуса линии Li e S a e De ec (рисунок 2.12). Уровень PMD генерирует для PHY признак присутствия оптического сигнала Sig al De ec , если мощность входного сигнала превышает -43.5 dBm, а снимает его при уменьшении этой мощности до -45 dBm и ниже. | |
