产品概述
JC3303 光话机/光源一体机主机是聚测公司研制的新一代智能光仪表,广泛应用于数字数据网,电信网和有线电视等光纤线路工程的施工、检测、维护及光纤衰减测量,可实现单纤双向全双工通信,通话品质高,不会因为距离远近而有所不同使用,无需用户设定,当讲话双方接线相连,话路随即自动建立,并有大屏幕及LED指示,使用户非常容易使用。该新型仪表外观流畅,手感好,贴心的人性化设计,操作简单方便,满足用户的需求。
产品特色:
1.具有单纤全双工通信模式,数字和模拟混合调制
本光话机是利用空闲光纤作话音通信的光电话机,使用数字和模拟混合调制,使语音通话非常清晰流畅。
2.大动态范围:45dB
3.长距离通话:120km
4.自动建立连接功能
当光话机接入光纤链路中,自动检测及建立一个通话
5.具有频率光调制光源功能。
光源可以发出连续光及270Hz、330Hz、1KHz、2KHz的调制频率光(TONE),频率光一般用于光纤的识别。
