我局引进日本NEC5500系列的光传输设备,包括140Mb/s光端机、140Mb/s数字复用器,以及2/8/34Mb/s数字复用器.这些设备已使用八年多,总的说比较稳定,故障率较低,但由于使用的年限较长,元器件不断老化,也随时会出现一些故障.那么如何及时、准确、迅速地排除随机出现的故障呢?本人根据实践体会,对上述设备运转中的主要故障和处理方法进行了规纳,将分三部分陆续进行介绍.本文先介绍第一部分:光端机的主要故障和处理方法.
Our bureau introduced the optical transmission equipment of Japan NEC5500 series, including 140Mb / s optical transceiver, 140Mb / s digital multiplexer and 2/8 / 34Mb / s digital multiplexer, which have been used for more than eight years. Stable, low failure rate, but due to the use of a longer period of time, the components continue to aging, but also at any time there will be some failure.So how timely, accurate and rapid rule out random failures? I practice based on the above equipment The main fault in operation and the way to deal with the regulation, will be introduced in three parts one after another.This paper first describes the first part: the main failure of Optical and processing methods.
