Qhov txawv ntawm Simplex thiab Duplex Fiber Optic Cables
Thaum sib tham txog fiber ntau optic thaj cable, cov khoom muaj feem xyuam thaum xub thawj tuaj rau peb lub hlwb mas feem ntau multimode thiab ib hom fiber ntau cable.Thaum kawg, tseem muaj ntau ntau hom. Tab sis raws li ib tug pib tshiab nyob rau hauv daim teb no tej zaum yuav xav li cas duplex thiab simplex fiber patch cables yog. Daim ntawv no yuav qhia koj txog cov cables. Ua ntej peb tuaj yeem tuaj yoojyim rau cov kabmob yooj yim thiab lub duplex fiber ntau lub cab, peb xub paub ob lo lus - simplex thiab ob lub tsev.
Yuav ua li cas Ua Simplex thiab Duplex Txhais?
Raws li ITU-T txhais, ib qho yooj yim Circuit Court yooj yim yog ib qho uas qhov kev taw qhia muaj peev xwm khiav hauv ib qho kev taw qhia ib zaug. Ib kawg yog lub transmitter, thaum lwm tus yog lub receiver thiab uas tsis yog thim rov qab.
Txawm li cas los, nyob rau lwm lub sijhawm, kev sib txuas lus tuaj yeem khiav hauv kev rov qab. Ntawd yog ib nrab-duplex. Ib nrab-duplex system txhais tau hais tias ib txoj kev sib txuas lus uas ua haujlwm nyob rau hauv ib qho kev taw qhia ib zaug thiab tej zaum yuav rov qab kho dua. Ib qho zoo sib xws rau ib nrab-duplex system yuav yog ob txoj kev nrog ib lub tsheb khiav ntawm txhua qhov kawg, txhawm rau kom txoj kev khiav ntawm cov tsheb khiav, cov tsheb khiav lag luam tsuas pub ib qho kev taw qhia ib zaug xwb. Tab sis yog tias ib tog neeg sib kis tau tib lub sij hawm, kev sib tsoo tshwm sim, ua rau cov lus tsis zoo.
"Duplex" los ntawm "duo" uas txhais tau hais tias "ob", thiab "plex" yog hais txog "weave" los yog "fold". Ib lub duplex system muaj ob txoj kev qhia meej meej rau txhua txoj kev uas muab cov ntaub ntawv hauv ib qho kev coj, uas yog A rau B tshaj ib txoj hau kev, B rau A dhau ntawm lwm qhov. Muab piv nrog ib nrab-duplex, ib qho tag nrho-duplex system, lossis qee zaus hu ua double-duplex tso cai rau kev sib txuas lus ntawm ob qho kev qhia thiab tso cai rau qhov no tshwm sim ib zaug. Ib yam li tus xov tooj ntawm tes, ob tog neeg tuaj yeem hais lus thiab tau hnov tib lub sijhawm.
Simplex Fiber Optic Cable:
Simplex Fiber Optic Cables yuav raug siv thaum lub teeb liab tsuas xav mus rau hauv ib qho kev coj. Lawv yog tsim los rau kev tshem tawm ntau qhov uas qhov sib npaug thiab kev tsis meej yog qhov tseem ceeb heev rau kev khiav ceev thiab ua haujlwm sai.
Simplex Fiber Optic Cable muaj ib tus fib kis, nruj-buffered (coated nrog 900 micron tsis nyob hauv thawj tsis txheej) nrog Cov Neeg Sivlar (aramid fiber) zog thiab cov neeg siv rau sab hauv tsev, thiab feem ntau yog siv cov kab nrob qaum thiab daim ntaub ntawv . Analog rau cov ntaub ntawv cov ntaub ntawv nyeem, cov kev sib tw hauv kev tsheb ciav hlau, thiab kev sib zog ceev thiab ciam teb sensors (rau kev siv cov kev ua si) yog txhua yam kev siv Simplex fiber optic cable. Daim foos ntawm cov nplaum no muaj peev xim yoo dua Duplex cables, vim tias cov khoom siv tsawg dua. Simplex Fiber Cable yog ib lub tshuab muaj fiber ntau nyob hauv ib hom, multimode, los yog polarization, thiab lawv muaj peev xwm ua tau raws li lub zog thiab kev tsim nyog rau hnub no lub fiber ntau interconnect ntawv. Peb kuj muab Khoom Noj Tsuag, Plenum rated sau thiab LSZH tsho.
Duplex Fiber Optic Cable:
Duplex Fiber Optic Cables muaj ob lub fibers txuas los ntawm kev sib ceg sib txuas ntawm ob lub tsho loj. Xijpeem ib hom los sis multimode, lawv siv rau hauv cov ntawv thov uas cov ntaub ntawv xav tau xa mus rau bi-directionally. Ib tug fiber ntau cov ntaub ntawv qhia ib qho kev taw qhia; lwm cov ntaub ntawv muaj fiber ntau hauv cov lus qhia. Cov chaw haujlwm loj, keyboards, cov chaw zov me nyuam, thiab kev sib tshua ntawm kev sib txuas lus tseem ceeb heev yuav tsum tau siv lub tshuab fiber ntau optic cable.
Duplex fibers hom:
Ib Nrab Duplex: Cov ntaub ntawv tsuas yog xa tawm hauv ib qho kev taw qhia ib zaug xwb.
Full-duplex: Cov ntaub ntawv yog xa mus rau ob qho kev qhia ib txhij.
Lwm yam kev sib txuas ntawm ob qho tib si: Ib qho kev sib txuas lus ntawm duplex yog ib qho taw rau-taw-taw uas muaj ob tog los yog cov cuab yeej uas sib txuas lus nrog ib leeg rau ob qho tib si, ib txhij. Tam sim no, Duplex systems ua hauj lwm hauv ntau tes hauj lwm sib txuas lus, los mus tso cai rau kev sib txuas lus "ob txoj kev" sib txuas nruab nrab ntawm ob tog neeg los yog muab txoj kev "rov qab" rau kev saib xyuas thiab kev hloov chaw rau khoom hauv thaj chaw.
Qee Cov Kev Qhia Kom Xaiv Simplex Thiab Duplex Fiber Cable
Thaum nriav cov khoom siv fiber ntau, nws yog qhov tseem ceeb kom nkag siab qhov sib txawv ntawm ntau yam ntawm cov tub ntxhais cov yam ntxwv uas muaj nyob rau hauv lub tshuab nws tus kheej. Txhua yam ntawm cov cwj pwm txawv no nyias muaj nyias qhov txawv txav ntawm koj lub peev xwm xa cov ntaub ntawv nti tawm, thiab cov yeeb yam sib txawv no kuj cuam tshuam rau qhov kev sib tw cabling. Koj yuav tsum nrhiav tus nqi hluav taws xob fiber optic cable yog tias koj yuav lub cable. Tam sim no, cia saib ntawm cov kab mob fiber ntau tshaj plaws.
Simplex Fiber Cable
Ib qho yooj yim fiber ntau cable muaj ib txoj kab ntawm cov iav ntawm cov yas fiber ntau, thiab yog siv rau cov ntawv thov uas tsuas yog siv cov ntaub ntawv xa tawm. Simplex fiber ntau yog siv ntau qhov sib txuas nkaus xwb thiab tau txais kab yog qhov nruab nrab ntawm cov khoom siv los yog thaum siv cov ntaub ntawv siv ntau lub vev xaij (siv ob txoj kev sib txuas lus dua ib leeg). Simplex fiber ntau muaj nyob rau hauv singlemode thiab multimode. Piv txwv, ib qho chaw tsheb loj thauj neeg uas xa tawm qhov nyhav ntawm lub tsheb mus rau ib qho chaw nres tsheb los yog ib tus neeg saib xyuas roj uas xa cov ntaub ntawv ntsig txog cov roj mus rau qhov chaw hauv nruab nrab.
Duplex Fiber Cable
Ib lub duplex fiber ntau cable muaj ob txoj hlua khoob ntawm iav los yog yas. Feem ntau pom muaj nyob hauv "zipcord" (ib sab ntawm ib sab) kev siv, cov kab no feem ntau siv rau kev sib txuas lus ntawm duplex nruab nrab ntawm cov chaw xa khoom sib txuas thiab tau txais kev pab. Duplex fiber ntau muaj nyob rau hauv singlemode thiab multimode. Siv ntau hom fiber ntau fiber ntau optic cable los yog ib hom duplex fiber ntau rau cov kev siv uas yuav tsum tau hloov mus rau ib qho kev hloov mus rau ob qho tib si. Workstations, fiber ntau keyboards thiab servers, cov qauv fais fab, thiab kho vaj tse zoo li yuav tsum tau duplex fiber ntau cable.
Cable Tsim Cov Qauv Rau Cov Pulling Zog, Kev Tiv Thaiv Dej, Fiber Code Kev Ntsuas
Pulling Zog: Ib txhia cable tsuas yog muab tso rau hauv lub phaj kab xov los yog cov kwj deg. Yog li rub lub zog tsis tseem ceeb heev. Tab sis lwm txoj kab yuav raug muab rub tawm los ntawm 2 km lossis ntau tshaj ntawm conduit. Txawm nrog ntau lub roj nplua nyeem, rub lub nro yuav siab. Feem ntau cov cab txais lawv lub zog los ntawm ib qho tshuaj fiber ntau, ib lub tshuab fais fab polymer uas muaj zog heev tiam sis tsis ncab - rub tawm rau nws yuav tsis ntxhov siab rau lwm yam khoom hauv kab. Tus simplest simplex cable tau rub lub zog ntawm 100-200 phaus, thaum sab nraud cog kab mob yuav muaj ib qho kev tshaj tawm ntawm 800 phaus.
Dej Kev Tiv Thaiv: Tawm sab nraud, txhua kab hlau yuav tsum raug tiv thaiv los ntawm dej los yog ya raws. Nws pib nrog ib lub tsho tiv taus lub tsho, feem ntau PE (polyethylene), thiab ib daim ntawv sau txog cov dej-thaiv cov khoom. Txoj hauv kev li ib txwm yog kom muaj kev nyab xeeb ntawm cov kab mob uas muaj dej thaiv cov hlaws. Nws zoo tab sis ntxhov siab - yuav tsum tau muaj cov kua nplaum (remover). Ib qho tshiab yog qhov thaiv dej thaiv kom tsis txhob siv cov txuj ci tseem ceeb - cov khoom tsim los nqus dej noo hauv cov ntaub qhwv caj dab. Tshawb xyuas nrog koj lub lag luam cable los saib seb lawv puas kam.
Cov Kev Ntsuas Hluav Taws Xob (Fire Code Ratings): Txhua qhov cable hauv tsev sab hauv yuav tsum tau ntsib hluav taws teeb. Nws txhais tau tias lub tsho tiv no yuav tsum tau siv rau kev tua hluav taws, feem ntau siv rau kev siv, riser (kab ntsig cable feeds ntau dua kab rov tav) thiab plenum (rau kev teeb tsa hauv cov cua tshuab. nyob hauv Teb Chaws Asmeskas, txhua qhov chaw cab yuav tsum nqa cov ntawv pov thawj thiab kev pom tsis tseeb rau NEC (National Electrical Code) nqe lus 770.
