Q: MTP / MPO cable yog dab tsi?
A: MTP thiab MPO yog ntau- fiber ntau connectors uas nqa 8, 12, 16, lossis 24 fibers hauv ib lub ferrule. Lawv yog qhov tseem ceeb rau kev sib txuas ntawm optics xws li 100G-SR4, 400G-DR4, thiab 400G-SR8, qhov twg ntau txoj kab khiav ib txhij ntawm transceivers. MTP yog hom tshwj xeeb ntawm MPO- ua raws li cov khoom sib txuas nrog cov tshuab ua kom nruj dua.
Q: Puas yog fiber ntau zoo dua tooj liab hauv cov ntaub ntawv chaw?
A: Fiber yeej rau ib qho kev sib txuas tshaj li ob peb meters ntawm 100G lossis siab dua, rau txhua qhov txuas uas yuav tsum ncav cuag tshaj ib lub khib ntawm kev kub ceev, thiab rau txhua txoj hauv kev uas EMI muaj kev txhawj xeeb. Copper tseem yeej luv luv hauv -rack server txuas (DAC), PoE- cov khoom siv hluav taws xob, thiab tawm- ntawm -band tswj.
Q: Yuav ua li cas koj kuaj fiber ntau optic cabling nyob rau hauv ib tug data center?
A: Peb txheej: kawg-kev tshuaj xyuas lub ntsej muag tiv thaiv IEC 61300-3-35 cov txheej txheem, kev ntsuas qhov poob ntawm txhua qhov channel, thiab OTDR kuaj ntawm lub cev ntev lossis qhov twg cov nyiaj poob qis nruj. Cov txiaj ntsig kev xeem dhau los ua ib feem ntawm cov ntaub ntawv xa mus thiab lub hauv paus rau kev daws teeb meem yav tom ntej.
Q: Kuv yuav tsum khaws cia ntau npaum li cas fiber ntau?
A: Khaws 30-50% spare strand suav rau ib txoj kev. Tus nqi marginal ntawm cov fibers ntxiv nyob rau hauv ib qho ua ntej - txiav lub cev yog me me. Tus nqi ntawm rub lub pob tw thib ob los ntawm ib nrab ntim tais ob xyoos tom qab tsis yog.

Fiber optic cabling yog lub hauv paus ntawm txhua qhov chaw cov ntaub ntawv tsim los kom kav ntev tshaj li ib tiam optics. Tau txais nws txoj cai yog tsawg dua ntawm cov cable nws tus kheej thiab ntau ntxiv txog kev txiav txim siab nyob ib puag ncig nws: kev nrawm nrawm, qib fiber ntau, cov kab txuas txuas, txoj kev polarity, txuas pob nyiaj siv, thiab lub peev xwm seem. Network architects uas kaw cov kev txiav txim siab nyob rau hauv kev sau ntawv ua ntej thawj lub cev raug txiav kom xaus nrog cable nroj tsuag uas nqus 100G rau 400G rau 800G migrations gracefully. Cov pab pawg uas ncua cov kev txiav txim siab no feem ntau rov tsim dua hauv tsib xyoos.
Xaiv rau qhov optics koj yuav tau khiav hauv peb lub xyoos, tsis yog cov uas koj tau khiav xyoo tas los. Document lub channel kawg kom kawg. Ntsuam xyuas txhua qhov txuas tawm tsam tus qauv luam tawm. Khaws lub peev xwm seem hauv txhua txoj hauv kev. Kev qhuab qhia raug nqi me ntsis ua ntej thiab them rov qab rau txhua qhov kev txav mus los, ntxiv, thiab hloov pauv rau lub neej ntawm qhov chaw.
