Siv 10G Infrastructure Rau 40G Ethernet Nrog 40G BiDi Optics

Siv 10G Infrastructure rau 40G Ethernet Nrog 40G BiDi Optics

Thaum lub sij hawm tsiv teb tsaws ntawm 10G txog 40G, yog ib qhov teeb meem mob taub hau ntau tshaj yog tias 10G cov cuab yeej sib txawv ntawm 40G. Piv txwv li, 40GASE-SR4 QSFP + transceiver yog cov tshuaj tua tau tshaj plaws rau 40G kis tau sai. Nws siv plaub txoj kab 10G kom txhawb 40G los ntawm 12-fiber ntau MTP / MPO interface, nrog rau plaub tau txais thiab plaub rau kev xa thiab cov fib fab so tsis siv. Txawm li cas los, nyob rau hauv kev sib txuas 10G, ib tug duplex fiber optic thaj cable yog txaus, nrog ib tug fiber ntau rau tau txais thiab lwm yam kev xa. Qhov sib txawv no yuav tsum muaj kev hloov ntawm cov vaj tse thaum kho kom zoo dua 10G network rau 40G network. Yog hais tias 40G QSFP + transceiver rau luv nrug tseem siv cov duplex kis tau tus mob, tej yam yuav yooj yim dua. Yog vim li cas peb thiaj li muaj 40GBASE-SR BiDi QSFP transceiver. Qhov no 40G BiDi optics targeting ntawm 40G Ethernet yuav tiav tag nrho cov kis tau thiab tau txais los ntawm lub duplex LC thaj cords.

Cov pub leejtwg ntawm no 40G BiDi transceiver rau luv nrug yog raws li lub wavelengths. Siv plaub txoj kab sib txawv, qhov 40G BiDi QSFP siv ob lub duplex 20G kis sib kis ntawm ob lub fibers. Hauv kev yooj yim, txhua tus fiber optic yuav tsum nqa ob 20G cov teeb meem ntau tshaj ob seem wavelengths (feem ntau yog 850nm thiab 900nm). Lub teeb liab raug xa mus rau lub hom phiaj ntawm 850 nm ntawm ib tus fiber ntau. Lub teeb liab ntawm lub hom phiaj ntaus kis tau los ntawm 850 nm ntawm lwm cov fiber ntau. Qhov no kuj ua haujlwm rau cov teeb meem ntawm 900 nm, raws li muaj nyob hauv daim duab nram qab no.

Qhov no yog vim li cas 40GBASE-SR BiDi QSFP transceivers tau txhawb 40G Ethernet los ntawm kev siv lub duplex LC thaj hlua. Sib piv nrog cov kev cai txuas 40G rau luv nrug, 40GBASE-SR BiDi QSFP transceivers yog ncaj. Hloov lub 10G optics los ntawm 40 G BiDi QSFP optics thiab tsis muaj lwm daim cassettes ntxiv, koj tuaj yeem muaj 40G Ethernet.

Lub hwj chim ntawm 40GBASE-SR BiDi QSFP yog qhov tsis tas rau kev yeem yooj yim dua 40G txoj kev tsiv teb tsaws chaw. 40G BiDi QSFP kuj tuaj yeem txo qhov nqi rau 40G cabling. Cov tsos 40G luv nrha kev txuas feem ntau ua ntej 12-fiber ntau MTP / MPO pob tw cab cab nrog OM3 / OM4 fibers, uas yog kim tshaj LC multimode thaj thaj. Hauv kev ntxiv, rau ze li ntawm 95% ntawm peb qhov chaw nruab nrab cov kev sib txuas yog tsis pub ntev tshaj 200 meters. Lub 40G BiDi optics tuaj yeem txhawb 40G Ethernet li 100 meters (OM3) thiab 150 mais (OM4). Qhov ntawd txhais tau hais tias 40GBASE-SR BiDi QSFP muaj peev xwm them rau ntau yam siv nyob rau hauv cov ntaub ntawv xov xwm. Nrog cov hlua LC siv, ntau qhov chaw tau txais kev cawmdim. Thiab cov ntaub ntawv chaw muaj peev xwm muaj cua txias.

Yog tias tsis hloov 10G cabling infrastructure, koj muaj peev xwm muaj 40G Ethernet los ntawm kev siv 40GBASE-SR BiDi QSFP transceivers thiab duplex LC thaj hlua. Lub rooj nram qab no muaj 40GBASE-SR BiDi QSFP cov khoom siv. Yuav kom ua tau raws li cov kev sib dhos siab nyob rau hauv cov chaw khaws ntaub ntawv, ib tug tshiab version ntawm LC thaj cords nrog thawb-pull tab.
