Yuav kho qhov muag fiber ntau hloov network cable?Optical fiber yog ib hom iav fiber ntau, uas xa cov teeb liab kho qhov muag thiab tsis tuaj yeem txuas ncaj qha rau lub network cable.Nws yuav tsum tau siv cov cuab yeej hloov pauv photoelectric los hloov cov teeb liab kho qhov muag rau hauv cov teeb liab network.Cov khoom siv photoelectric hloov dua siab tshiab muaj xws li tsev neegoptical fiber cat khoom, optical fiber transceiver thiab Optical hloov.
1.Home fiber optic modem khoom
Fiber optic modemstseem hu ua fiber optic modems.Nws lub luag haujlwm tseem ceeb yog ua cov teeb liab hloov dua siab tshiab.Nws yog ib qho khoom siv relay siv rau kev sib txuas lus network "Fiber optic modem" feem ntau yog siv rau kev sib kis deb tshaj 20KM thiab ceev tshaj 2M.Cov khoom siv kho qhov muag xws li SDH / PDH yog xav tau nyob rau hauv nruab nrab.Nyob rau hauv cov ntaub ntawv ntawm kis tau tus mob, ib tug optical modem yog siv, uas yog tsuas yog ntsia rau ntawm ob qho tag nrho ntawm ib tug optical fiber thiab converts cov ntaub ntawv kis tau tus mob ntawm hluav taws xob teeb liab thiab optical signals.Thaum kho qhov muag broadband tau teeb tsa hauv tsev, optical modems yog siv los hloov cov teeb liab kom cov khoos phis tawj thiab lwm yam khoom siv tuaj yeem paub txog cov teeb liab no.Tam sim no optical modems txuas xov tooj, TVs, broadband, routers thiab wireless Internet nkag.
2.Optical fiber ntau transceiver
Optical fiber ntau transceiveryog ib yam ntawm cov khoom siv photoelectric hloov dua siab tshiab uas sib pauv cov kab hluav taws xob luv luv twisted-pair hluav taws xob thiab cov teeb liab nyob deb.Lub teeb liab kho qhov muag yog tawm tswv yim los ntawm qhov chaw nres nkoj kho qhov muag thiab cov teeb liab hluav taws xob yog qhov tso tawm los ntawm qhov chaw nres nkoj hluav taws xob (RJ45 crystal head interface).Cov txheej txheem yog hloov hluav taws xob teeb liab mus rau hauv cov teeb liab kho qhov muag thiab xa lawv los ntawm fibers optical.Ntawm qhov kawg, cov teeb liab kho qhov muag tau hloov mus rau hauv cov teeb liab hluav taws xob, thiab tom qab ntawd txuas nrog routers, keyboards thiab lwm yam khoom siv.
Raws li kev sib kis deb, lawv tuaj yeem muab faib ua ib hom thiab ntau hom transceivers.① Ib hom optical fiber ntau transceiver: qhov kis tau tus mob nyob nruab nrab ntawm 20 kilometers thiab 120 kilometers;②Multi-mode optical fiber transceiver: qhov kis tau tus mob nyob nruab nrab ntawm 2 mais thiab 5 mais.
Nyob rau hauv txoj kev sib kis, fiber ntau optic transceivers yuav tsum tau siv ua khub, haum rau kev ncua deb tshaj 100 meters, txhua qhov taw qhia lub teeb sawv cev rau lub ntsiab lus sib txawv, 1000-thaum nws nyob, nws sawv cev rau 1000M tus nqi, 100-thaum nws nyob, nws sawv cev. 100M tus nqi;FX- Thaum nws nyob rau, nws txhais tau hais tias lub pigtail txuas nrog, thiab thaum nws flashing, nws txhais tau hais tias cov ntaub ntawv raug xa mus; FX LINK / ACT - thaum nws nyob rau, nws txhais tau hais tias lub network cable txuas nrog, thiab thaum twg. nws yog flashing, nws txhais tau hais tias cov ntaub ntawv raug xa mus;thaum nws yog nyob rau, nws txhais tau hais tias lub hwj huam qaum txuas;TX LINK / ACT — -Thaum nws nyob rau, nws sawv cev rau tag nrho-duplex tus nqi, thiab thaum nws tawm, nws sawv cev rau ib nrab-duplex.
3.Photoelectric hloov
Optical hloovyog ib hom kev sib txuas lus network relay khoom.Qhov txawv ntawm nws thiab hloov pauv zoo tib yam yog tias nws siv fiber ntau optic cable raws li qhov nruab nrab kis tau tus mob.Nws siv fiber ntau channel nrog ntau dua kev sib kis tus nqi txuas nrog cov neeg rau zaub mov network lossis SAN network sab hauv kom tag nrho lub network muaj bandwidth loj heev, yog li tus nqi sib kis tau nrawm dua thiab muaj peev xwm tiv thaiv kev cuam tshuam muaj zog dua.
Muaj 2 optical 2 hluav taws xob, 4 optical 2 hluav taws xob, 8 optical 2 hluav taws xob thiab lwm yam photoelectric keyboards.4 optical 2 hluav taws xob txhais tau hais tias 4 optical fiber input ports thiab 2 RJ45 network chaw nres nkoj tso zis, uas tuaj yeem txhawb nqa 100M thiab Gigabit tes hauj lwm, tsim rau cov lag luam loj Ntau qhov sib kis ntawm fiber ntau optical.
