IC693MDL741IC693MDL741一、 OTDR測試
1.測試方式:利用OTDR進(jìn)行光纖線路的測試,一般有三種方式,自動方式,手動方式,實(shí)時方式。當(dāng)需要概覽整條線路的狀況時,采用自動方式,它只需要設(shè)置折射率、波長最基本的參數(shù),其它由儀表在測試中自動設(shè)定,按下自動測試(測試)鍵,整條曲線和事件表都會被顯示,測試時間短,速度快,操作簡單,宜在查找故障的段落和部位時使用。手動方式需要對幾個主要的參數(shù)全部進(jìn)行設(shè)置,主要用于對測試曲線上的事件進(jìn)行詳細(xì)分析,一般通過變換、移動游標(biāo),放大曲線的某一段落等功能對事件進(jìn)行準(zhǔn)確定位,提高測試的分辨率,增加測試的精度,在光纖線路的實(shí)際測試中常被采用。實(shí)時方式是對曲線不斷的掃描刷新,由于曲線在不斷的跳動和變化,所以較少使用。
