MTP Txuas Kev Ua Zoo Tshaj Plaws: Tshaj Lij Zauv thiab Cheeb Tsam Qis
Nrog lub ntsaws ntsev uantej ua ntej & ua si cov kev pabcuam thiab yooj yim ntawm scalability ntawm 10-40-100G, MPO / MTP connectors yog ua qhov hloov ntawm kev sib txuas hloov. Nyob hauv tsab xov xwm dhau los "Introduction to MPO Connector", Kuv tau tham txog ob hom MPO connectors-12 fiber MPO connector thiab 24 fiber ntau MPO connector. Thiab ob hom MPO / MTP ob hom siv tau rau kev xa xov 100G. Li ntawd, ib tug neeg yuav nug "kev sib txuas ntawm kev sib txuas ntawm MTP, puas muaj qhov sib txawv ntawm ntau tus neeg suav thiab qis dua, los sis, uas ua tau zoo dua, kev ua qoob siab dua los sis qis dua? Cov ncej no tsuas qhia cov lus teb.
Feem ntau, qis tag nrho cov kev kho qhov muag poob zuj zus ntxiv rau lub network khiav lag luam, los yog hauv rooj plaub rau qee cov neeg siv, muaj kev xaiv ntau dua kev sib txuas rau thaj chaw ua haujlwm. Tom qab ntawd, qee qhov network designers hais tias muaj fiber ntau dua yuav ua rau kev nkag siab dua. Qhov tseeb, qhov pom ntawm no tsis yog. Rau ob qho tib si 12-fibre thiab 24-fiber MPO connector kev ua tau zoo, qhov kev lag luam ntaus nqi yog qhov siab tshaj 0.5 dB. Thaum siv hom kev txhuam kom zoo, 24-fiber MPO / MTP terminations yuav ua tau raws li tib theem qib ua tau li 12-fiber MTP assemblies. Txuas ntxiv, siv cov qis qis, ob qho tib si 12 fibre thiab 24 fiber ntau MPO connectors tuaj yeem nyob ntawm 0.35 dB siab tshaj.
Raws li koj paub, ob qho tib si MPO 24 fiber ntau cable thiab MPO 12 cable siv tau rau hauv 100G daim ntaub ntawv. MPO 12 cable yuav siv tau rau 4x25G daws, ntxiv 4 fibers tsis siv. Thaum siv MPO 24 fiber ntau cable, nws tuaj yeem raug hloov mus rau hauv peb daim 8-fibers 100G uas khiav dhau ib kab, nrog rau tag nrho 24 fibers siv los txhawb cov tsheb khiav. Cia peb qhia ib qho piv txwv rau qhov pov thawj uas zoo dua. Yog tias koj xav tau kev txhawb nqa kaum ob 100G raws nrog 4 x 25G txuj, siv 12 fiber ntau MPO cable, koj yuav tsum nruab 12 connectors, los yog 144 fibers tag nrho, nrog 33% ntawm lub fiber ntau. Siv MPO 24 fais fab cable txhawb tib lub sijhawm 12, tsuas yog 4 cables yuav tsum tau siv, siv 96 fibers tag nrho, ntawm 100% fiber ntau siv.
Los ntawm cov lus piav qhia saum toj no, peb tuaj yeem piav qhia tau tias MPO 24 fiber ntau cable tsis txhais cov ntsiab lus poob ntxiv thiab ua haujlwm nrog MPO 12 cable. Ntxiv mus, cov 24 fiber ntau MPO cable, thaum lub sijhawm uas siv rau kev siv tau 100GBASE-SR10 20-fiber ntau technology, tau tib lub sij hawm tsim kho cov peev txheej hauv kev lag luam thaum 4x25G kev pom zoo thiab qhov kawg siv. Kev xaiv MPO 12 cable tsuas ua tsis tiav qhov no vim nws tsav tsheb rov qab los ntawm peev thiab tom qab tsub kom tag nrho tus nqi ntawm cov tswv cuab. Thiab qhov no yog qhov tsis txaus siab kiag ntawm qhov kev tsim cov qauv ntawm ib qhov chaw nruab nrab ntawm cov ntaub ntawv.
