Txheej txheem cej luam ntawm Optical Switch:
Lub fiber optic switch yog lub cuab yeej xa xov hluav taws xob ceev ceev. Piv nrog rau cov switches ib txwm muaj, nws siv cov cables fiber optic ua cov khoom siv xa xov. Qhov zoo ntawm kev xa xov fiber ntau yog qhov ceev ceev thiab muaj peev xwm tiv thaiv kev cuam tshuam. Fibre Channel Switch (FC Switch, tseem hu ua "Fibre Channel Switch").
Lub qhov hloov fiber optic yog ib hom khoom siv tshiab, thiab muaj ntau qhov sib txawv ntawm cov qhov hloov Ethernet ib txwm siv (feem ntau yog pom hauv kev txhawb nqa ntawm daim ntawv cog lus). Huawei fiber optic Ethernet switches yog qhov kev tswj hwm siab hom ob txheej fiber optic Ethernet nkag mus. Tus neeg siv tuaj yeem xaiv qhov chaw nres nkoj tag nrho-optical lossis qhov chaw nres nkoj optical-electrical hybrid, thiab cov xov xwm fiber optical tuaj yeem yog ib hom fiber lossis ntau hom fiber. Lub qhov hloov tuaj yeem txhawb nqa kev tswj hwm network chaw taws teeb thiab kev tswj hwm hauv zos tib lub sijhawm kom paub txog kev saib xyuas qhov xwm txheej ua haujlwm ntawm chaw nres nkoj thiab qhov chaw teeb tsa.
Lub qhov chaw nres nkoj fiber ntau yog qhov tsim nyog rau cov xwm txheej uas qhov kev nkag mus ntawm qhov chaw ntaub ntawv tshaj qhov kev nkag mus ntawm kab Qeb 5, qhov xav tau kev cuam tshuam tiv thaiv hluav taws xob thiab qhov xav tau kev sib txuas lus zais cia, thiab lwm yam. Cov teb siv tau suav nrog: cov chaw nyob hauv tsev FTTH broadband access network; enterprise high-speed optical fiber LAN; high-reliability industrial distribution Control system (DCS); optical fiber digital video surveillance network; tsev kho mob high-speed optical fiber local area network; campus network.
Kev piav qhia txog kev hloov kho qhov muag:
Hom kev hloov pauv tsis thaiv khw-thiab-mus tom ntej, nrog 8.8Gbps hloov pauv peev xwm, txhua qhov chaw nres nkoj tuaj yeem ua haujlwm ntawm full-duplex ntawm qhov ceev tag nrho tib lub sijhawm
