Ethernet Thiab Fiber Optic Cabling
Txawm hais tias nyob hauv lub hnub nyoog ntawm WiFi thiab cov xov tooj ntawm tes ntawm tes ceev, peb tseem xav tau cov xaim hluav taws xob sib txuas ua ke kom peb lub khoos phis tawm ua ke. Ob qho tib si Ethernet cables thiab cov roj carbon fiber optic siv tau xa thiab xa cov naiskhu. Kev muab cov khoom lag luam nrawm, ruaj ntseg thiab txhim khu kev qha, cov kab no ua si sib txawv hauv kev xa cov kev lom zem thiab cov ntaub ntawv lag luam.
Ethernet Cable
Keeb kwm tau tsim los ntawm Xerox xyoo 1970, Ntu 5 thiab 6 cable, lossis Cat 7 cable txuas rau khoos phis tawj thiab tshuab kis las rau cov routers hauv peb tsev thiab chaw ua haujlwm. Pom tau hais tias lawv lub qhov rooj loj loj RJ45 yas sib txuas thiab zoo li cov xov tooj xov tooj ntawm tes, cov xov tooj no nqa tau cov ntaub ntawv ntsuas hauv ntau pua megabits hauv ib ob. Cov hluav taws xob ntau txoj kab hluav taws xob txuas kuj txuas cov routers rau cov qauv thiab khoom siv hloov, nyob ntawm lub network teeb tsa.
Ethernet cov ntaub ntawv tus nqi sib txawv nyob ntawm qhov siv cable. Qhov tshiab tshaj plaws Cat 7 cable, 10 Gigabit Ethernet, xa mus rau 10 Gbps. Qeb 7 thev naus laus zis txhim kho ob qho kev sib txuas sab hauv thiab sab nraud thaiv cov ntaub ntawv piv rau cov hlua qub CAT5 / CAT5e thiab CAT6 cov xaim hluav taws xob. CAT 7 cable txhawb nqa 10 Gigabit Ethernet network sib txuas, thiab CAT7 cov xaim hluav taws xob kuj tseem sib xws nrog cov qauv Ethernet adapters.Gigabit Ethernet xa mus txog 1 Gbps. Fast Ethernet, tseem yog qhov siv ntau tshaj cable siv hauv tsev thiab chaw ua haujlwm niaj hnub no, kis mus txog 100 Mbps (kwv yees li 0.1 Gbps).
Fiber ntau Optic Cable
Fiber optic cable thawj qhov thov kom muaj koob meej yog nws lub peev xwm los nqa cov ntaub ntawv ntau ntawm ntau cov chaw deb. Cov xov hluav taws xob fiber ntau yog nquag pom nyob ntawm cov chaw muab kev pab cuam hauv Internet qhov chaw nruab nrab rau cov chaw hauv ib cheeb tsam hauv ib puag ncig. Zoo kawg li, cov ntaub ntawv no yog nqa nrog iav los yog yas ua cov ntoo ua lub teeb. Nyob ntawm seb qhov kev pabcuam Is Taws Nem yog DSL lossis cable-raws, xov tooj xov tooj lossis coaxial cable ces ua rau txhua qhov chaw nyob. Cov kab rov tav fiber ntau cable tau ua rau cov neeg ua haujlwm muab cov kev kub ceev dua thiab cov ntaub ntawv nce ntxiv. Cov phiajcim ntawm cov hlua hluav taws xob fiber ntau tau rov ua dua lossis txhawb nqa kom them nyiaj rau cov teeb meem ploj mus deb.
Ntawm qhov nrug deb txog 1.86 mais, ib hom fiber ntau-optic cable tuaj yeem xa cov ntaub ntawv txog 10 Gbps, tab sis nws yog siv feem ntau rau cov yeeb yaj kiab. Nws yog siv feem ntau rau kev ua yeeb yaj kiab siab lossis los ua tus caj qaum kom txuas cov tes hauj lwm ntawm cov tuam tsev. Multimode fiber, uas yog siv rau lub suab, cov ntaub ntawv, thiab cov vis dis aus, muaj cov ntaub ntawv tus nqi nce mus txog 1 Gigabit ib pliag rau qhov kev ncua deb hauv qab 1.24 mais.
Multifiber Push-On ("MPO") cov ntsiab lus fiber ntau (xws li MPO rau LC cable) tau dhau los ua kev daws teeb meem rau cov kev ua tau zoo ntawm cov ntaub ntawv nruab nrab bandwidth. Vim tias lawv yog lub ntuj haum rau cov kab muag hluav taws xob txuas, cov kab hluav taws xob txuas no yog kev cog lus, ua ntej kaw, muaj peev xwm ua tau bandwidth txhua txoj hauv kev txog 100 Gbps, thiab txawm tias ntsaws thiab ua si los ntawm kev tsim.
Cov neeg ib txwm xav tias fiber ntau them rau cable yuav yeej tooj liab Ethernet cable txhais tes nqes. Txawm li cas los xij, cov tuam txhab cable tau txuas ntxiv hloov kho cov thev naus laus zis tom qab Ethernet, txhais tau tias nws tuaj yeem ua kom ceev nrawm zoo li qee cov kab ntsig fiber ntau hauv hnub no. Piv txwv li, Cat 7 cable yog ib txheej txheem tshiab txuas nrog cabling tshuab txuas mus txog 10 Gbps. Thaum Ethernet cable thiab fiber ntau them cable muaj qhov sib txawv kiag li, fiber ntau kho qhov muag cable siv tau hauv Ethernet tes hauj lwm. Ehernet cable nqe thiab fiber ntau them nqe cable kuj tsis zoo li qub, xaiv Ethernet cable lossis fiber ntau them cable koj yuav tsum coj nws mus rau hauv kev txiav txim siab.
