A: Txawm tias ib qho me me los yog khawb tuaj yeem ua rau poob thiab kev cuam tshuam thiab tig qhov txuas sib txuas. Kev tshuaj xyuas tiv thaiv IEC 61300-3-35 thiab ntxuav ua ntej txhua qhov kev sib txuas tiv thaiv kev ua txhaum uas kim kim dua tom qab.
Q: Dab tsi yog OTDR siv rau hauv OSP tes hauj lwm?
A: OTDR nrhiav qhov kev ncua deb mus rau ib qho kev tshwm sim thiab qhia txog kev poob, khoov cov xwm txheej, thiab fiber ntau so. Ib yam li qhov tseem ceeb, qhov kev lees paub dhau los ua lub hauv paus uas qhov kev ua txhaum yav tom ntej - nrhiav yog ntsuas tawm tsam.
Q: OSP tus nqi tu yuav txo tau li cas?
A: Los ntawm kev tau txais cov txheej txheem tsim nyog: kev sib khi kom raug, txhim kho txoj kev thiab khoov kev tswj xyuas, ua tiav cov ntaub ntawv xeem, cov ntawv ntshiab thiab daim ntawv qhia chaw nres nkoj, thiab kev tshuaj xyuas kev tiv thaiv uas ntes drift ua ntej nws yuav tawg.
Q: Cov ntaub ntawv dab tsi yuav tsum suav nrog hauv OSP xa?
A: Yam tsawg kawg nkaus: IL/RL cov txiaj ntsig, OTDR cov cim, qhov kawg - daim ntawv qhia txog kev tshuaj xyuas lub ntsej muag, daim ntawv qhia chaw nres nkoj, txoj kev ID, thiab kaw thiab daim ntawv lo duab. Cov ntaub ntawv no yog dab tsi ua rau kev kho tom ntej sai es tsis yog kev tshawb nrhiav.
Tsim OSP Kev Sib Txuas Uas Nyob Hauv Cov Nyiaj Txiag
Sab nraum zoov fiber ntau tsis feem ntau ua tsis tiav nyob rau hauv nruab nrab ntawm lub cable - nws tsis ua hauj lwm ntawm qhov chaw txuas, thiab nws ua tsis tau ua ntej raws li poob drift, paug, los yog lub foob tawg. Xaiv cov khoom tawv tawv, zoo- cov khoom kaw thiab ua ke nrog kev soj ntsuam nruj, kev sau npe, thiab cov ntaub ntawv lees paub yog qhov ua kom muaj kev sib txuas ruaj khov thiab ua rau cov tsheb thauj khoom tawm ntawm cov peev nyiaj tu.
Yog tias koj tab tom qhia txog kev kaw, lub thawv xa khoom, MSTs, xaim cable, lossis FTTA thiab cov rooj sib tham armored rau OSP tsim,hu rau pab neeg Glorykom phim cov khoom tsim nyog rau txhua qhov kev pheej hmoo hauv koj lub network.
