Qhov kev thov rau cov neeg siv xov tooj sib txuas hauv cov chaw zov me nyuam yog nyob rau qhov nce, tshwj xeeb nrog kev siv ntau dua ntawm 17,286 core lossis 34,566 core optic cables hauv cov chaw loj loj. Txuas cov fiber ntau rau cov servers thiab keyboards yog qhov tseem ceeb vim tias qhov chaw tso khoom yog txwv. Fiber faib ncej yog qhov tseem ceeb ntawm kev daws qhov kev sib tw no. Txhawm rau daws qhov teeb meem no, cov tuam ntxhab kev lag luam tau nce qhov chaw nres nkoj ntom ntom hauv qhov chaw faib khoom kom tau raws li qhov xav tau nce bandwidth.
Ib qho kev sib tw rau lub chaw nruab nrab cov ntaub ntawv yog ua kom siv qhov chaw muaj txiaj ntsig zoo. Txhua qhov khib feem ntau muaj 42 khib-hlwb (RU) lossis 48 khib-hlwb (RU), thiab lub hom phiaj tseem ceeb yog siv qhov chaw no rau xa cov chaw ntau li ntau tau. Qhov tseeb, qhov tsawg dua koj muaj rau lub Cheebtsam passive, ntau qhov chaw koj muaj rau cov khoom siv nquag. Cov ntaub ntawv chaw nruab nrab cov kws ua lag luam xav kom ua qhov siv ntau tshaj plaws ntawm cov chaw muaj txiaj ntsig cov chaw hauv chaw kom xa cov khoom siv sib txuas hauv network, thiab nce qhov chaw nres nkoj yog qhov kev daws teeb meem zoo.
Tib lub sijhawm, hais txog kev sib txuas ua ke, cov chaw siv cov ntaub ntawv nruab nrab siv cov kev siv sib txawv thiab cov cuam tshuam muaj fiber ntau. Qee tus siv cov kev sib txuas serial, thaum lwm tus siv cov kev sib txuas mus txuas ntxiv kom nce bandwidth. Qhov tsim nyog, passive infrastructure thiab kab rov tav cabling muab ntau li ntau tau thiab modularity li sai tau kom tsis txhob yuav ntau yam ntawm cov xov hlau kev daws teeb meem kom tau raws li cov kev xav tau sib txawv. Network txuas cov qauv tseem tab tom hloov zuj zus: simplex SC thiab duplex LC tau nrov hauv lub xyoo. Tus txheem compact serial connector hom yog noj nyob rau hauv qhov tseeb" txuas kev tsov kev rog" ;. Nyob rau xyoo kaum lub xyoo dhau los, kev sib txuas cov tshuab sib txuas tau ua tiav zoo.
Tab sis qhov ua tau zoo ntawm cov kab sib txuas ntawm lub network tau txhim kho, thiab txhua tus xav tau qhov siab tshaj plaws rau xaiv cov hom ntawm cov khoom siv sib txuas. Seb txhua qhov chaw nres nkoj duplex txuas nrog ob kab hluav taws xob, lossis txhua qhov chaw nres nkoj muaj ntau qhov sib txuas sib txuas ntawm cov khoom sib txuas hauv ib txhij. Nws tau muaj pov thawj tias txhua qhov chaw nres nkoj muaj 72 tus xov tooj hluav taws xob nrog MTP, thaum nws nquag muaj rau txhua qhov chaw nres nkoj MPO / MTP muaj 24 tus xov tooj tseem ceeb. Chaw nres nkoj nyiam tuaj yeem hloov tau los ntawm cov ntawv txuas mus rau qhov sib txuas txuas, thiab thaum kawg cov kab txuas sib txuas thev naus laus zis. Yog tsis muaj lub platform uas hloov tau, tus lej ntawm Macs uas yuav ntsib tom ntej yuav raug txwv thiab lub sijhawm ntawm kev nqis peev yuav raug txwv.
Lub tshuab txuas txuas yog qhov chaw sib txuas ua ke los ntawm kev xam cov khoom siv thiab lub xov tooj tseem ceeb. Thaum lub sijhawm pib xa tawm, tus neeg siv yuav tsum tau siv cov ntaub thaiv npog thaiv thiab lub tshuab rau cov chaw nres nkoj ntawm daim txiag tswj hwm. Cov neeg siv xav tau txoj kev tswj xyuas cable zoo (xeeb thaum lub sijhawm tsim platform thiab xa tawm ntawm lub sijhawm teeb tsa) thiab nkag mus rau cov chaw nres nkoj. Hauv qee qhov kev teeb tsa ntawm cov vaj huam sib luag, qhov yuav tsum tau nkag rau hauv pem hauv ntej thiab nram qab ntawm vaj huam sib luag tuaj yeem cuam tshuam qhov yooj.
Qee cov neeg muag khoom muag yias teeb nrog cov khoom hloov kho uas yuav muab ntau cov chaw nres nkoj rau ib lub vaj huam sib luag, tab sis lawv tsis quav ntsej ntawm kev tswj hwm cable thiab tsis muaj qhov hloov pauv lossis cov qauv. Cov ntoo uas tshem tau tau muab cov chaw nres nkoj zoo dua, tab sis feem ntau tsis tshua hloov thiab hloov tau.
Feem ntau ntawm cov kev daws teeb meem no pub tsawg modularity, yog li cov neeg siv yuav tsum paub txog cov chaw nres nkoj thaum mus yuav khoom siv panels. Tsis tas li, tsis muaj chaw ua vaj huam sib luag rau qhov chaw nres nkoj thaum lub chaw nres nkoj ntawm cov vaj huam sib luag ruaj ruaj yog qhov ntim ntawm qhov siab tshaj plaws. Nrog cov vaj huam sib luag ruaj khov, cov qauv siv vaj huam sib luag tej zaum yuav txawv ntawm qhov chaw ntawm 1RU vaj huam sib luag kom ua tiav qhov ntom ntom qhov siab tshaj plaws, xav tau 2RU, 3RU, lossis ntau qhov chaw khib kom ua tiav qhov chaw siab tshaj qhov chaw nres nkoj.
Cov tsoos modular txuas tsim txwv qee cov tuam ntxhab rau 72 chaw nres nkoj ib chav khib (RU). Qee tus neeg muag khoom muaj lub vev xaib tsis hloov uas tsis yog hloov tau. Lwm cov kev daws teeb meem faus chaw nres nkoj kom ua kom muaj kev cuam tshuam rau Automated Infrastructure Management (AIM) tov, kev lag luam thev naus laus zis uas tiv thaiv ntau tus neeg muag khoom los ntawm kev ua kom muaj fiber ntau. Tsis tas li ntawd, ntau tus neeg muag khoom tsis xav qhia cov platform tshiab uas tsis sib xws nrog cov platforms yav dhau los.
