MTP-8 Kev Tiv Thaiv: Kev Txawj Ntse Yav Tom Ntej-Ntawv Qhia Hauv Cov Ntaub Ntawv Xov Xwm
Hauv feem ntau cov chaw zov me nyuam, MTP cable yog dav siv rau kev ceev ntom ntawv. MTP-12 txuas thiab MTP-24 connectivity yog ob hom kev sib txuas sib txuas, uas siv kev txuas raws li qhov sib tw ntawm 12 thiab 24, xws li 12-fiber ntau lub cev cab thiab 24-fiber ntau lub cev cab. Ntxiv rau MTP-12 thiab MTP-24, muaj lwm MTP kua-MTP-8. Hauv cov kua tshuaj MTP 8 los yog Base-8, 8-fibre cables, 24-fibre lossis 32-fibre cables yuav siv tau los xa cov ntaub ntawv. Hauv cov lus luv luv, MTP-8 cov kev siv siv kab kev txuas raws li ntawm increments ntawm tus xov tooj "yim". Tus ncej no yuav piav qhia cov txiaj ntsig ntawm MTP-8 tov thiab qhia nws daim ntawv thov hauv 10G / 40G cov chaw khaws ntaub ntawv.
Nrog MTP-12 thiab MTP-24 siv nyob rau hauv cov ntaub ntawv chaw rau lub xyoo, koj yuav nug seb yog vim li cas tseem muaj kev xav tau rau MTP-8? Nyob rau hauv fiber optic kev lag luam, optical transceiver roadmap hloov sai ntawm 10G-40G-100G thiab txawm mus txog 400G (saib cov duab hauv qab no). Nrog ceev ceev kis tawm mus rau hauv cov ntaub ntawv chaw racks thiab SANs, muaj kev xav tau rau ntau hom kev pabcuam. Rau 40G kev sib txuas thiab saum toj no, cov ntaub ntawv feem ntau yog nqa yim fibers, thiab txiav ntawm qhov kev hloov ntawm MTP-8 QSFP transceiver uas yog muab yim yim daim fibers.
Ntawm daim duab, peb tuaj yeem pom tias Ethernet kis tau li ntawm 40G txog 400G, txhua txoj kev ua rau 2-fiber thiab 8-fiber ntau tov. Rau 40G / 100G thiab yav tom ntej 400G daim ntaub ntawv, kev siv 12-fiber MTP daws yuav ua rau 33% ntawm qhov muag fibers tsis siv. Li no nws yuav tsum hais tias rau 400G daim ntawv thov, MTP-8 yuav tau txais thoob plaws kev lag luam kev txaus sab.
Flexibility thiab siv 100% fiber ntau yog qhov zoo tshaj plaws ntawm MTP 8. Ua kom raws li cov naj npawb "2", cov tshuaj MTP-8 tau yooj yim siv rau ob lub tshuab hluav taws xob transceiver, xws li MTP-12 daws tau. Thiab rau cov neeg uas tau npaj muaj 12-fibre lossis 24-fibre cables, yuav ua li cas kom 100% fiber ntau siv? MTP-8 tau. Koj tuaj yeem siv cov hlua hloov khoom siv los yog cov khoom siv rau kev hloov ob 12-fiber los yog ib lub cev 24-fiber ntau ntawm pob qaum cabling mus rau peb 8-fiber ntau MTP rau 40G / 100G cov khoom txuas. Tab sis, txoj hauv kev ua no, kev hloov ua ke yuav ua kom muaj qhov tso quav ntxiv rau hauv cov casses thiab hloov cords. Yog li deploying MTP-8 daws ncaj nraim yuav xyuas kom 100% fiber ntau siv tsis tau ntxiv cov nqi thiab insertion poob ntawm MTP-12 rau MTP-8 conversion devices. Nyob rau hauv ib lo lus, rau ntau yam hom 40G / 100G / 400G transceiver hom, MTP-8 tov muaj kev yooj yim tshaj plaws thiab siv cov fibers rau lub siab dawb paug.
Raws li tau hais los saum toj no, MTP-8 daws tau siv rau hauv cov ntawv thov sib txawv. Ntawm no kuv xav pom peb yam piv txwv.
Hauv 40G qhov chaw khaws ntaub ntawv, txoj kev nyuaj mus txuas ob qhov txuas 40G yog siv lub MTP pob tw tshuab. Raws li daim duab qhia, 40 G cov ntaub ntawv kis tau los ntawm kev siv ob hnub ntawm MTP lub cev pob hlau nrog 40G QSFP kev hloov xov mus rau ob txoj hlua 40G.
Rau 10G rau 40G tsiv teb tsaws, siv MTP breakout cable yog ib txoj kev yooj yim. Raws li pom hauv daim duab nram qab no, MTP rau LC breakout cable txuas ib tug 40G transceiver thiab plaub 10G transceivers. Yog li 40G cov ntaub ntawv yuav kis tau los ntawm 10G hloov mus rau 40 G mus los ntawm MTP rau LC breakout cable.
Dhau li ntawm siv MTP breakout cable mus cuag 10G rau 40G migration, koj tuaj yeem siv lub MTP LC thaj vaj huam sib luag kom tiav 40G cov ntaub ntawv xa tawm. Daim duab hauv qab no qhia tau tias txoj kev sib txuas. Lub 96 fibers MTP LC thaj ua haujlwm ua raws li tus nruab nrab ntawm 10G 40G kev twb kev txuas. Nws muaj kaum ob-8 fibre MTP adapters rau ntawm lub tsheb thiab kaum ob 8 fibers fiber ntau LC rau sab xub ntiag. MTP LC thaj chaw ua haujlwm txuas 40G QSFP cov chaw nres nkoj nrog MTP lub cev pob zeb txuas mus rau tom qab ntawm lub vaj huam sib luag thiab tom qab ntawd tawm li 48 x 10G nyob rau pem hauv ntej nrog LC thaj hlua.
Kev txhawb cov kev siv cov ntaub ntawv tam sim no thiab yav tom ntej 8, MTP-8 yog qhov tseem ceeb tshaj plaws thiab cov txheej txheem txuas rau yav tom ntej. Txhua tus neeg uas muaj kev npaj nyob ze-tern tsiv teb tsaws los mus txais yuav 40G los yog 100G hauv cov chaw khaws ntaub ntawv yuav pom txiaj ntsim zoo rau kev sib txuas lus MTP-8. Nyob rau txhua qhov, MTP-8 kev daws teeb meem tuaj yeem ua kom cov chaw zov me nyuam muaj peev xwm ua tau zoo tshaj plaws, cov ntaub ntawv pov thawj yav tom ntej, muaj kev yooj yim dua migration uas teev tawm mus rau 400G kis.
