Sab hauv ntawm lub cable yog tooj liab tub ntxhais hlau;sab hauv ntawm optical cable yog iav fiber.Lub cable feem ntau yog ib txoj hlua zoo li txoj hlua uas tsim los ntawm kev sib tw ob peb lossis ob peb pawg ntawm cov xov hlau (txhua pawg tsawg kawg yog ob).Cov kab hluav taws xob kho qhov muag yog ib txoj kab kev sib txuas lus uas yog tsim los ntawm qee tus xov tooj ntawm cov khoom siv kho qhov muag hauv ib txoj hauv kev thiab tau them nrog lub plhaub, thiab qee qhov kuj tau them nrog lub tsho sab nrauv kom paub txog kev xa xov hluav taws xob.
Thaum lub xov tooj hloov cov teeb liab acoustic rau hauv lub teeb liab hluav taws xob thiab tom qab ntawd xa mus rau qhov hloov ntawm txoj kab, qhov hloov pauv xa cov teeb liab hluav taws xob ncaj qha mus rau lwm lub xov tooj ntawm kab lus teb.Cov kab sib kis thaum sib tham no yog ib kab.
Thaum lub xov tooj hloov cov teeb liab acoustic rau hauv lub teeb liab hluav taws xob thiab xa mus rau qhov hloov ntawm txoj kab, qhov hloov pauv hloov hluav taws xob teeb liab mus rau lub tshuab hloov hluav taws xob photoelectric (hloov cov teeb liab hluav taws xob rau hauv lub teeb pom kev kho qhov muag) thiab xa mus rau lwm lub tshuab hloov hluav taws xob photoelectric. ntawm kab (hloov cov teeb liab kho qhov muag).Lub teeb liab hloov mus rau hauv lub teeb liab hluav taws xob), thiab tom qab ntawd mus rau cov khoom siv hloov pauv, mus rau lwm lub xov tooj los teb.Cov kab ntawm ob lub photoelectric hloov dua siab tshiab yog ib qho kev kho qhov muag cable.
Lub cable feem ntau yog tooj liab tub ntxhais hlau.Cov tub ntxhais hlau diameters muab faib ua 0.32mm, 0.4mm thiab 0.5mm.Qhov loj ntawm txoj kab uas hla, qhov muaj zog ntawm kev sib txuas lus muaj peev xwm;thiab raws li tus naj npawb ntawm cov tub ntxhais xov hlau, muaj: 5 khub, 10 khub, 20 khub, 50 khub, 100 khub, 200 Yog, tos.Optical cables tsuas yog muab faib los ntawm cov xov tooj ntawm cov tub ntxhais, cov xov tooj ntawm cov tub ntxhais: 4, 6, 8, 12 khub thiab lwm yam.
Cable: Nws yog qhov loj me, qhov hnyav, thiab tsis muaj peev xwm sib txuas lus, yog li nws tsuas yog siv rau kev sib txuas lus luv luv xwb.Optical cable: Nws muaj qhov zoo ntawm qhov me me, qhov hnyav, tus nqi qis, muaj peev xwm sib txuas lus loj, thiab muaj peev xwm sib txuas lus zoo.Vim muaj ntau yam, nws tam sim no tsuas yog siv rau qhov ntev thiab taw tes rau-taw tes (ie, ob chav hloov pauv) kev sib txuas lus.
Qhov tseeb, qhov sib txawv ntawm cov cables thiab optical cables feem ntau tshwm sim hauv peb yam.
Ua ntej: Muaj qhov sib txawv ntawm cov khoom siv.Cables siv cov khoom siv hlau (feem ntau yog tooj liab, txhuas) ua cov khoom siv hluav taws xob;optical cables siv iav fibers ua conductors.
Thib ob: Muaj qhov sib txawv ntawm cov teeb liab kis tau tus mob.Lub cable xa hluav taws xob teeb liab.Optical cables xa cov teeb liab kho qhov muag.
Thib peb: Muaj qhov sib txawv ntawm qhov kev thov.Cov kab hluav taws xob tam sim no feem ntau yog siv rau kev xa xov hluav taws xob thiab cov ntaub ntawv xov tooj qis kawg (xws li xov tooj).Optical cables feem ntau yog siv rau kev xa cov ntaub ntawv.
Hauv kev siv tswv yim, nws tuaj yeem paub tias cov kab hluav taws xob kho qhov muag muaj peev xwm kis tau zoo dua li cov tooj liab cables.Lub relay seem muaj qhov ntev, me me, lub teeb yuag, thiab tsis muaj kev cuam tshuam electromagnetic.Tam sim no nws tau tsim cov kab ntev-ntev kab, intra-city relays, offshore thiab trans- caj qaum ntawm dej hiav txwv submarine kev sib txuas lus, nrog rau cov kab xaim xaim rau hauv cheeb tsam network, kev sib koom tes ntiag tug, thiab lwm yam, tau pib tsim rau hauv thaj chaw. ntawm cov neeg siv lub voj kev faib tawm hauv nroog, muab cov kab sib kis rau fiber ntau rau hauv tsev thiab broadband kev pabcuam digital network.
