Kho qhov muag lub suab cable

Rau hnub tim, ib tug kho qhov muag lub suab cable - ib qho ntawm feem niaj hnub thiab txhim khu kev qha txoj kev rau cov ntaub ntawv kis tau tus mob. Fiber optic cov ntaub ntawv kis tau tus mob yog tau siv lub teeb. Raws li sawv daws paub, lub teeb - ib yam ntawm cov ceev tshaj plaws nyob rau hauv lub ntiaj teb no ntawm tshwm sim, yog li ntawd nws yog tsim nyog los nkag siab txog dab tsi yog qhov no cable, yuav ua li cas nws ua hauj lwm thiab dab tsi yog yuav tsum tau.

Teeb yog ib tug electromagnetic yoj ntawm siab zaus. Yog hais tias nws kis tau los ntawm ib tug optical fiber, nws yuav ib txhij nqa ib tug heev loj npaum li cas ntawm cov ntaub ntawv. Yog li no txoj kev ntawm kis tau tus mob yog ruaj khov thiab muaj ib tug high kev tiv thaiv rau electromagnetic tawg. Thaum dua los ntawm tus kho qhov muag fiber teeb yoj decays - nws nyob ntawm lub transparency thiab lwm yam khoom muaj los ntawm ib tug optical fiber, nyob rau hauv particular, ib tug kho qhov muag lub suab cable.

Cia saib nyob rau hauv ntau yam ntawm cov piv txwv ntawm cov kho qhov muag cable DAXX R07. Nws tsim los ntawm lub khob fibers uas muaj ib theem siab ntawm transparency. Tsis tas li ntawd, nws muaj tsawg dispersion coefficient uas saib kuas ruaj khov ntaub ntawv kwj thiab cov kev kub ceev ntawm lub teeb. Vim hais tias ntawm cov khoom, R07 kho qhov muag lub suab cable interconnects nyob rau hauv lub tsev neeg yog xam tau tias yog ib tug ntawm qhov zoo tshaj plaws, ces nws yog zoo meej rau tsev ua yeeb yam high-end chav kawm ntawv.

Khob fiber ntawm lub cable yog 280 fine fibers. Thickness ntawm fibers 53 microns. Txhua fiber lacquered tshwj xeeb paab txheej uas muaj ib tug high refractive index - nws txhawb nqa lub tsim ntawm ib tug tus khiav ntawm lub teeb nrog tus nqi qis tshaj tau attenuation. Qhov no tsim muaj siab stability thaum Identify loj nyiaj ntawm cov ntaub ntawv, uas yog vim li cas rau lub suab Pib ntsais koj teeb, kho qhov muag cable R07 yog ib tug ntawm qhov zoo tshaj plaws.

Yuav kom tiv thaiv cov neeg kho tshuab kev puas tsuaj zoo strand fiber puv tshwj xeeb tsis, thiab ib tug muab ob npaug rau txheej ntawm polyvinylchloride siv rau ntau yooj ntawm tag nrho cov qauv. Los ntawm ntau dabtsi yog khoov cable tiv thaiv lub txheej nylon screen. Nws yog xim hlau connectors muab durability daim ntawv thov.

Ua ntej fais coaxial cable kho qhov muag lub suab cable muaj ob peb qhov tsav:

- Optics muaj lub peev xwm mus rau kis loj nyiaj ntawm cov ntaub ntawv;

- los ntawm txoj kev ntawm ib tug optical fiber yuav ua nruab nrab ntawm ob lub Cheebtsam ntawm lub rho tawm ntawm "lub ntiaj teb." Qhov no yog tshwj xeeb tshaj yog muaj tseeb thaum lub computer system unit txuas mus rau lub receiver.

High-zoo fiber optic cable yog kim heev. nws realization kuj yog kim (txog li $ 40-50). Yog hais tias cov khoom yog ib qhov nyuaj nyiaj txiag coj kom zoo dua ntawm "optics", li ntawd nws yog ntau heev es tsis txhob ntawm ib tug kho qhov muag cable, cov neeg siv xaiv ib tug cheaper coaxial cov cable.

Feem ntau, cov tub txawg yog nug seb koj xav mus yuav ib tug kim cable, vim hais tias feem ntau ntawm cov satellite receiver yog txawm peem rau nrog ib tug optical cov zis? Yog li ntawd, Nyob zoo cable yog tsis yog tshwj xeeb uas yuav tsum tau. Cov satellite TV suab zoo yog tsis heev (cov suab ntaub ntawv kwj muaj ib tug uas tsis muaj ntsis nqi), yog li ntawd ib tug optical suab cable, koj yuav tau yuav tus uas yooj yim rau cov hom phiaj, uas raug tus nqi txog 10-12 dollars.
