为什么光信号是红灯
光纤猫信号灯闪红灯,表示此时不能上网,因为光纤猫接收不到信号。
可能由以下几种情况导致:
室内尾纤连接光猫接头松脱,把接头插好即可恢复。
光猫本身故障,收光器部分损坏也会造成这种现象。
室内部分光纤弯折过大。光纤弯折过度会影响光信号在光纤内光的全反射传输,只要把光纤顺直即可。
室外部分光纤有折断或机房设备光端口故障,需要联系工作人员进行报障处理。
光信号闪红灯是什么原因?
光信号闪红灯就是光信号中断了,原因及解决 *** 如下:
一、室内尾纤连接光猫接头松脱或者接触不良,这种情况需要将接口拨下清理下然后重新插回试试。
二、室内部分光纤弯折过大。光纤弯折过度会影响光信号在光纤内光的全反射传输,只要把光纤顺直即可。
三、光猫光接口有问题,这种情况属于光猫硬件问题,只有将光猫送修至 *** 或者更换一个新的光猫。
四、宽带欠费,现在宽带业务基本都是后付费模式,运营商会因 *** 欠费过久而关闭宽带服务,这种情况只需缴清欠费即可。
不同的光纤接入技术有不同的适用场合:
有源光接入技术适用带宽需求大、对通信保密性高的企事业单位的接入。它也可以用在接入网的馈线段和配线段,并与基于无线或铜线传输的其他接入技术混合使用。
ATM-PON既可以用来解决企事业用户的接入,也可以解决住宅用户的接入。有的运营商利用“ATM-PON+xDSL”混合接入方案,解决住宅用户或企事业用户的宽带接入。
光信号闪红灯是怎么回事
光信号亮红灯说明光猫光口收无光告警,有以下几种情况:
1、光猫光接口有问题,需要更换光猫。(这种情况比较少见)。
2、室内尾纤连接光猫接头松脱。把接头插好即可恢复。
3、室内部分光纤弯折过大。光纤弯折过度会影响光信号在光纤内光的全反射传输,只要把光纤顺直即可。
4、室外部分光纤有折断或运营商机房设备光端口故障,需要找运营商处理。

宽带上光信号亮红灯是怎么回事
光信号灯闪烁主要有以下几个方面:
1、机房光口发光较低或不发光,造成用户端光猫工作不正常,此时光信号灯收不到光缆上发来的光信号或收光信号功率过低,会造成光猫跟机房握手不正常,此时光信号灯会闪亮或者红灯告警。
2、光缆故障(包括分光器坏),也会造成光猫处收不到光或收光过低,此时光信号灯也会闪亮或者红灯告警。
3、光猫本身故障,收光器部分损坏也会造成这种现象。
以上三种状况不管哪种出现,用户基本都无法自行排除故障,只能打 *** 报障通过运营商的维修人员来处理。
