Процедура очистки соединителей, кассет и кабельных сборок MPO
LC и SC и FC адаптеры Вставьте ватную палочку для очистки в открытый проходной адаптер. Вращайте ватную палочку по часовой стрелке, изменяя силу нажатия и совершая плавные движения вперед и назад, чтобы конец ватной палочки контактировал наконечником. Проверьте качество очистки с помощью микроскопа и при необходимости повторите шаги 1 и 2, пока загрязнения не будут удалены. После использования утилизируйте ватную палочку. Кассета/Адаптер […]
