Kuv puas tuaj yeem rov siv kuv qhov OM4 cabling uas twb muaj lawm rau kev hloov kho 100G?
Feem ntau, yog - muab qhov txuas txuas thiab cov peev nyiaj poob yog nyob rau hauv cov lus qhia rau 100G optic koj xaiv. Yog tias koj cov OM4 txuas tau pib ua rau 10G lossis 40G, lawv tuaj yeem ua tau raws li qhov yuav tsum tau ua rau 100GBASE-SR4 (txog 100 m) lossis 100G BiDi (txog 100 m ntawm OM4). Ntsuam xyuas cov kev sib txuas nrog lub ntsuas hluav taws xob kho qhov muag kom paub tseeb tias qhov poob qis ua ntej xa 100G optics.
Dab tsi yog qhov txawv ntawm 100G thaj cable thiab 100G AOC?
Patch cable yog passive fiber jumper siv nruab nrab ntawm lub pluggable transceiver thiab ib thaj vaj huam sib luag (los yog lwm lub transceiver). IbAOC (Active Optical Cable)muaj transceivers txuas mus tas li ntawm ob qhov kawg - koj ntsaws nws ncaj qha rau hauv ob qhov chaw hloov pauv. AOCs yooj yim dua rau luv luv txuas txuas; thaj cables nrog pluggable transceivers muab kev yooj yim dua rau kev tswj hwm infrastructure.
Thaum twg kuv yuav tsum xaiv ib qho - hom hla multimode rau 100G?
Xav txog ib qho - hom thaum twg qhov txuas siab tshaj 150 m, hla lub tsev ciam teb, xav tau kev tawm sab nraud, lossis xav tau kev txhawb nqa yav tom ntej mus rau 400G lossis dhau ntawd yam tsis tau hloov fiber ntau. Tib -hom OS2 fiber ntau tus nqi ntau dua ib lub 'meter' dua li multimode, tab sis tag nrho cov nqi ntawm cov tswv cuab feem ntau sib tw thaum koj ua rau lub neej siv tau ntev dua thiab kev sib tw ceev dua.
Puas yog polarity tseem ceeb rau 100G MPO kev sib txuas?
Yog, thiab nws tseem ceeb tshaj li ntau tus installers paub. Nyob rau tib lub sijhawm - optics txuas siv MPO, txhua txoj hlua fiber ntau nqa ib txoj kab tshwj xeeb 25G. Yog tias qhov polarity tsis ncaj ncees lawm - lub ntsiab lus xa cov fibers tsis ua raws li qhov sib txuas tau txais fibers ntawm qhov kawg - qhov txuas yuav ua tsis tau lossis ua yuam kev. Tus qauv TIA-568 txhais tau peb txoj kev polarity (Hom A, Hom B, Hom C), thiab koj cov hlua khi, lub cev cables, thiab MPO adapters yuav tsum ua raws li tib txoj kev tsis tu ncua.
Kuv yuav ua li cas thiaj paub tseeb tias kuv qhov txuas 100G yuav ua haujlwm ua ntej yuav nyob?
Yam tsawg kawg nkaus, ua qhov kev ntsuam xyuas qhov poob nrog lub ntsuas qhov ntsuas qhov muag ntawm qhov kev ua haujlwm wavelength. Sib piv cov kev ntsuas poob rau lub transceiver qhov teev cov neeg txais kev xav tau thiab cov peev nyiaj poob. Rau kev sib txuas tseem ceeb, ntxiv ib qho OTDR kab los kuaj xyuas cov xwm txheej npaj txhij txog ntawm txoj kev. Thiab ib txwm tshuaj xyuas txhua qhov txuas kawg ntawm lub ntsej muag nrog lub tshuab ntsuas fiber ntau - ib kauj ruam no tiv thaiv feem ntau ntawm 100G xa tawm teeb meem.

Xaiv txoj cai 100G fiber optic cable tsis yog hais txog kev nrhiav cov nplooj ntawv khoom nrog "100G" hauv lub npe thiab ntxiv rau koj lub laub. Txoj kev daws teeb meem yog los ntawm kev sib piv cov transceiver interface, qib fiber ntau, hom connector, txuas qhov deb, thiab cov kev xav tau hloov kho yav tom ntej rau hauv cov qauv tsim.
Rau feem ntau luv luv - ncav cuag cov ntaub ntawv chaw txuas, OM4 multimode nrog duplex LC lossis MPO connectors tseem yog qhov ua tau zoo. OM5 ntxiv tus nqi tiag tiag nkaus xwb hauv BiDi lossis SWDM cov xwm txheej uas koj xav tau ncav cuag tshaj 100 m ntawm multimode. Rau ib yam dab tsi ntev dua, lossis qhov twg koj xav tau qhov kev hloov pauv siab tshaj plaws yav tom ntej, OS2 ib leeg - hom ua ke nrog qhov tsim nyog 100G optic - seb DR, FR, LR4, lossis ZR - yog qhov kev nqis peev uas muaj zog dua.
Koj cov kauj ruam tom ntej zoo tshaj plaws: tshawb xyuas cov qauv transceiver tshwj xeeb hauv koj qhov hloov lossis NIC, ntsuas qhov tseeb ntawm txoj kab kev deb, paub meej tias hom connector, thiab tom qab ntawd xaiv qhov sib txuam fiber ntau. Cov khoom siv ntawd- thawj txoj hauv kev ua rau muaj txiaj ntsig zoo dua li kev yuav khoom los ntawm lo lus tseem ceeb ib leeg. Yog tias koj xav tau kev pab cuam fiber ntau optic thaj qaum los yog cov khoom txuas rau koj qhov kev xa tawm 100G, pab pawg txhawb nqa tuaj yeem tshuaj xyuas koj qhov txuas tsim thiab pom zoo ua ke kom raug.
