ＳＣ/AＰＣ-SC/APCPre-Connectorized Optical Fiber Drop Cable tsim ua ntej
1. FTTH cable raug txiav rau hauv qhov ntev sib txawv raws li qhov yuav tsum tau ua rau thaj qaum, feem ntau ntawm 1m mus rau 300m, tab sis peb kuj tuaj yeem txiav raws li lwm cov kev cai.Qhov no yog thawj kauj ruam hauv kev ua cov hlua khi.
2. Muab cov khoom txuas txuas ua ntej, ua ntej strippe tawm optic fiber ntau.
3.Strip tawm cov fiber ntau optical thiab muab tso rau ntawm connector accessoires ib tug los ntawm ib tug.Qhov ntev ntawm qhov kho qhov muag fiber ntau yuav tsum tau muab tso tseg kom yooj yim rau kev ua haujlwm tom ntej.
4.hoting solidify: Txhawm rau kom ntseeg tau tias lub zog tensile ntawm qhov sib koom ua ke tuaj yeem ncav cuag 120N, peb yuav tsum kho qhov sib koom tes nrog cov kua nplaum tshwj xeeb.Ntawm no, lub sijhawm kho yog ib thiab ib nrab teev.Peb ncua lub sijhawm kho thiab ua kom lub zog tensile nrog qhov loj ntawm cov hlau qhov chaw.
5.Joint tsau: Cov txheej txheem no tseem ceeb heev, uas txiav txim siab qhov sib koom ua ke muaj zog.Peb tau lengthened qhov loj ntawm cov ntawv hlau thiab ua kom cov kua nplaum ntau ntxiv, kom cov sib koom ua ke ntau tensile.
6. Sib dhos connector
7.Grinding optic fiber kawg: SC / APC thiab SC / UPC Cov txheej txheem sib tsoo sib txawv.Txhua qhov kev sib txuas ntawm fiber ntau yuav tsum tau ua hauv av.Lub kaum sab xis ntawm kev sib tsoo nws txawv nrog lub connector.
8. Tshawb xyuas thiab kuaj.Txhua qhov txuas yuav tsum tau 100% kev soj ntsuam kawg thiab cov ntaub ntawv xeem
