国产软光缆生产线,做1~12芯软光缆,紧包加芳纶填充,最近生产单模缆时数据总是时好时坏(多模一切正常,偶尔会有问题),芯数越大越严重.1550平均衰减2点几,3点几,有的有台阶.(紧包下来数据都是0.6以下的).一直找不到原因.最先考虑是芳纶用量过少,紧包和护套有粘结,增加芳纶用量,紧包线过滑石粉,把本来拆下没用的SZ绞又重新装上,都没有效果. 后来又考虑放线张力,芳纶张力,主机温度,包括冷却水温等因素,一一都调整过.也无改善. 而且1KM有台阶总是集中在700~800M之间. 有的数据不好,倒盘之后会变好一点.以上问题困扰多时,求高手指点.....

简单点就是单模软光缆4芯以上1550过不了，紧包线弯曲粘线

1將填充當作其中1c以起過sz絞入2捲取張力降低軸桶徑變大

8B1和12B1没填充啊

排线情况如何，放线张力注意，管内空间是否太小了，模具选配等

我感觉还主要是考虑磨具的原因。。。。还有就是芳纶纱不要太紧 。。可以试着做松点试试

我们也出现这个问题，特别是8-12芯，不知道楼主的滑石粉装置是怎么样的，我们的感觉不是很理想，另外想问下楼至12芯你们外径做多大？
