Ncaj Nris Kab Txuas Cab
Nyob rau hnub no qhov chaw khaws ntaub ntawv, ntau ntxiv rau cov khoom siv bandwidth los txhawb cov kev siv xov xwm puas-ua haujlwm uas yuav tsum tau muaj cov ntaub ntawv xa tawm ntau ntawm kev loj hlob. Tso cov kab txuas ncaj qha tau tsim los ua nqi-tsawg thiab tsis muaj hwj chim txaus siab rau txoj kev sib koom ua ke xws li kev sib koom ua ke. Tsab ntawv sau no sau txog nws cov lus qhia txog kev qhia ncaj nraim, xws li kev txhais, kev faib tawm thiab kev siv 40GbE nrog QSFP.
Muab cov hlua txuas ncaj qha (DAC), ib hom kev kho kom sib nkag hauv kev sib txuas lus, yog ib daim ntawv ntawm lub xov tooj cua ntawm "high-speed" nrog rau "kev hloov cov yeeb yaj kiab" rau ob qhov kawg siv los txuas mus rau cov chaw khiav tsheb lossis cov neeg siv khoom. DACs yog cov pheej yig dua li cov kev siv hluav taws xob txij thaum "cov nrais muag" rau ob hnub ntawm DACs tsis yog tiag tiag optics thiab lawv cov khoom tsis muaj qhov muag lasers. Hauv qhov chaw khaws thaj tsam network, data center, thiab high-performance computing connectivity, lawv yog cov xaiv zoo rau lawv cov uas tsis muaj nqi, tsis muaj zog, thiab ua yeeb yam siab.
Muaj cov qauv sib txawv thaum muaj kev cais ntawm DACs.
Raws li cov khoom siv cables siv, DACs poob rau ob hom: ncaj qha kom txuas cov tooj liab thiab cov nquag optical cables. Ua tib zoo saib ntawm daim duab hauv qab no kom paub txog cov ntaub ntawv uas pom tau hais txog lawv.
Ncaj Qha Txuas Caw Cov Teeb Meem-Lawv raug tsim los ntawm cov kev ua haujlwm losyog tsis sib xws. Ob leeg yog dav siv nyob rau hauv lub lag luam telecommunication. Piv txwv li, Cisco 40G QSFP + modules xa ob lub tshuab ua haujlwm tiv thaiv kab mob thiab tooj liab dhau passive. Zoo li QSFP-H40G-ACU10M, FOCC tau tshaj Cisco QSFP-H40G-ACU10M ua haujlwm dhau ntawm cov xaim tooj liab rau 40-gigabit txuas thiab ncav cuag lub luv nrug.
Active Optical Cables-AOC yog ib daim DAC. Nws siv hluav taws xob-rau-kho qhov muag ntawm lub hnub cable los txhim kho kev sib tw thiab kev ua kom zoo ntawm txoj kab kev lag luam thaum mating nrog hluav taws xob interface txheem. Sib piv nrog cov kab txuas txuas nrog tooj liab, nws qhov me me, kev tiv thaiv kab mob electromagnetic, kev sib tshuam txuas tsawg dua thiab ntev kis mus ua nws nrov ntawm cov neeg siv khoom. Cisco QSFP-H40G-AOC1M khiav hauj lwm ntawm cov khoom siv fais fab zoo rau kev ua haujlwm siab dua hauv 40GbE (Gigabit Ethernet).
Los ntawm Ethernet kev sib txuas tus nqi, 10G SFP + cables, 40G QSFP + cables, thiab 120G CXP cables muaj. Coj QSFP-H40G-CU1M piv txwv li, FOCC tshaj Cisco QSFP-H40G-CU1M sau txog kab ntsig txog tooj liab, thiab nws tuaj yeem txhawb tus nqi siab 40Gb / s rau luv nrug.
QSFP + DACs, raws li lub ntsiab lus tsawg kawg latency, yog dav siv hauv 40GbE. Lawv muaj 4 raws hauv ib lub interface, muab 3-4X ceev ntawm XFP, SFP +. Dhau li ntawm, kev siv QSFP + DACs modules yuav txuag tau nyiaj ntau ntau, vim tias lawv tawm cov kim optical lasers thiab qee cov khoom hluav taws xob. Kev ua nrov nrov nyob rau hauv luv luv kev kis kab, QSFP + DACs modules tuaj yeem tsim muaj kev kho kom zoo thiab kev yooj yim. QSFP + DACs yog ib qho qauv zoo nkauj rau 40GbE.
Tso ncaj qha cab cables, los ntawm aggregation, kuj muab kev qis dua qis dua rau kev ceev dua (100G) interconnects. FOCC muaj kev kawm siab thiab kev sib tham zoo DAC cov rooj sib tham. Dhau li 40G QSFP + cables khoom (QSFP-H40G-ACU10M, QSFP-H40G-CU1M, thiab QSFP-H40G-AOC1M) uas hais saum toj no, lwm yam 10G SFP + cables thiab 120G CXP cables khoom kuj muaj nyob hauv FOCC. Koj tuaj yeem mus saib FOCC kom paub ntau ntxiv txog DAC cov rooj sib tham.
