Puas yog tooj liab cable yeej pheej yig dua fiber ntau dua cable?

Kev siv nyiaj yog ib txwm yog ib qho tseem ceeb tshaj plaws thaum txhim kho cables. Qhov kev pom zoo dav dav yog tias tooj liab cable yog pheej yig thiab fiber ntau cable yog kim. Tseeb nws yog qhov tseeb hauv ob peb xyoo dhau los. Raws li cov tes hauj lwm loj tuaj, yog tooj liab Ces me nyuam pheej yig dua fiber ntau cov cables?

Dab tsi yog qhov sib txawv:

Tooj liab thiab fiber ntau cov cables yog ntau hom cable. Tooj liab cables, tseem hu ua RJ45 Ethernet cables, nqa cov ntaub ntawv los ntawm cov hluav taws xob cuam tshuam thiab yog qhov zoo tagnrho rau cov cim qhia. Muaj ntau ntau hom xov tooj liab hlau, xws li Cat5E, Cat6, Cat6a, Cat7, uas tuaj yeem ua tiav kev sib txawv kis ceev. Cat5 Ethernet Cables muaj nrawm li 10 MBPS ntawm ntau yam ntawm 100 meters. Hauv kev ua lag luam niaj hnub no, txawm li cas los xij, tooj liab tau txav nrawm dua thiab nrawm dua. Xeev-ntawm-tus-kos duab Catha Ethernet Cables Tam sim no tuaj yeem ncav cuag ntau dua 20 metres, tab sis yuav tsum paub tias nws muaj qhov txwv tsis txaus.

Txawv los ntawm tooj liab cables, cov xaim hluav taws xob muaj hluav taws xob muaj hluav taws xob muaj roj Yog li no, cov xaim hluav taws xob muaj kuab muaj kuab txhua qhov tsis siv tshuaj thiab tsis muaj zog rau xov tooj cua tiv thaiv kev cuam tshuam. Nws yog ib txwm ruaj dua tooj liab thiab tuaj yeem tiv taus cov chaw hnyav thiab huab cua harsher. Raws li kev nrawm, fiber ntau yeej nrog kev nrawm thiab ntev dua kis tau deb. Piv txwv li, ib hom-hom fiber ntau os2 tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 200km. Cov lus hauv qab no muab kev sib piv ntshiab ntawm tooj liab thiab fiber ntau cov cables.

Cov neeg ib txwm ntseeg tus nqi ntawm twisted-paired tooj liab cable yog pheej yig tshaj li ntawm fiber ntau optic cagbles. Puas muaj tseeb? Peb yuav tham nws hauv ob yam tseem ceeb hauv qab no.

Tus nqi them nyiaj

Vim yog cov txuj ci sib txawv ntawm fiber ntau ntawm fiber ntau optic thiab tooj liab cable, lawv muaj cov nqi sib txawv. Qhov kev cuam tshuam hluav taws xob hluav taws xob (EMI) ntawm kev tiv thaiv fiber ntau tuaj yeem txuag tau cov neeg siv khoom muaj fiber ntau hauv cov khoom kom tsis txhob muaj emi. Tab sis tooj liab cables xav tau qee qhov kev tiv thaiv, ntxiv rau tus nqi ntawm kev teeb tsa.

Tsis tas li ntawd, nyob rau hauv ntau cov xwm txheej, cov neeg siv yuav tsum tau faib cov khoom lag luam rau tooj liab hlau tes hauj lwm, tab sis kho qhov muag kho qhov muag tsis xav tau vim qhov deb. Ib qho yuav tsum tsis quav ntsej txog cov nqi sib txuas lus, cua txias, cua, nce (uninterruptible zog mov) hauv tooj liab cabling. Tag nrho cov nqi teeb meem no yuav tawm ntawm tus nqi ntxiv ntawm cov khoom siv fiber ntau ntawm cov cuab yeej siv fiber ntau. Yog li ntawd, yog tias ib qho txiav txim siab los tsim cov ntaub ntawv tshiab, xaiv rau kev siv fiber ntau yog ib puag ncig tooj liab ntau dua li lub tooj liab network ib puag ncig.

Tus nqi txhawb

Fiber ntau cov kab ke siv tsis ua rau hluav taws kub vim lub teeb tsis ntes hluav taws. Qhov no txhais tau tias Fiber ntau cov kab ke tuaj yeem txuag cov nqi tiv thaiv hluav taws. Thiab cov ntaub qhwv hluav taws xob muaj hluav taws xob muaj hluav taws xob tsis yooj yim dua, cov neeg siv khoom tsis tas yuav txhawj txog kev hloov lawv ntau li ntau zaus. Yog li, tus nqi txhawb nqa ntawm fiber ntau dua qis dua li tus tooj liab.

Ntawm qhov tod tes, qhov nce ntxiv rau fiber ntau cov qoob loo tau ua rau poob qis hauv cov nqi. Piv txwv li, ntawm FS.com, tus nqi 3-ko taw cable raug nqi $ 2.2, thiab ib qho 3-ko taw LC-TC-LC UPC DELLEX ib-nkaus-hom fiber ntau thaj kab qaum yog $ 3. Tus nqi sib txawv yog me me. Yog li ntawd, thaum tus nqi tooj liab cable yog piv nrog ntawm fiber ntau optic cable, tus nqi ntawm tooj liab cable tsis kim dua li ntawm fiber ntau optic cable.

Hauv kev xaus, tooj liab cable tsis yog ib qho kev xaiv pheej yig tshaj thaum piv rau tus nqi ntawm fiber ntau optic cable. Thaum tsim lub network tshiab, ib qho yuav tsum tsis txhob saib xyuas cov kev teeb tsa thiab cov nqi txhawb nqa ntawm cov kev daws teeb meem sib txawv no. Nws yog cov paub qab hau kom xaiv ib qho raws li qhov chaw teeb tsa teeb tsa tiag tiag.
