Fiber jumper - kuj hu ua afiber optic thaj qaum- yog luv, connectorized fiber ntau cable siv los txuas cov khoom siv ports, thaj vaj huam sib luag, thiab faib thav duab. Txhim kho ib qho zoo li yooj yim: ntsaws ob qhov kawg hauv, txav mus. Tab sis tus neeg twg uas tau taug qab qhov kev sib txuas qias neeg los ntawm peb lub racks thaum 2 teev sawv ntxov paub qhov ua haujlwm tiag tiag tshwm sim ua ntej thiab tom qab lub ntsaws.
Xaiv hom kev sib txuas tsis raug, hla kev tshuaj xyuas, yuam kom nruj khoov tom qab lub qhov rooj txee, lossis tsis nco qab daim ntawv lo rau ob qho tag nrho - ib qho ntawm cov no ua rau tsib-feeb thaj rau ib teev- txoj haujlwm daws teeb meem ntev. Cov lus qhia no taug kev los ntawm cov txheej txheem tag nrho: xaiv txoj cai jumper, npaj thiab ntxuav lub ntsej muag kawg, routing thiab txuas lub cable, thiab txheeb xyuas qhov txuas tom qab.
Dab tsi yog Fiber Jumper?
Lub fiber jumper yog lub Hoobkas- txiav fiber ntau cable nrog cov txuas ntawm ob qho kawg. Nws muab qhov hloov tau yooj yim, tshem tau kev sib txuas ntawm cov khoom siv network, cov khoom siv chaw nres nkoj, thiab patching infrastructure xws liODFs thiab thaj vaj huam sib luag.
Common connector tsev neeg muaj xws liLC, SC, FC, thiabST. Patch cords tuaj nyob rau hauv ib qho -hom thiab multimode versions, thiab nyob rau hauvsimplex los yog duplexkev tsim kho nyob ntawm daim ntawv thov.
Fiber Jumper vs Patch Cord: Puas muaj qhov sib txawv?
Hauv kev xyaum, "fiber jumper" thiab "fiber optic thaj qaum" xa mus rau tib yam khoom. Ob qho tib si piav qhia txog cov kab txuas txuas siv rau kev hloov kho qhov muag patching. Cov ntsiab lus sib txawv raws cheeb tsam thiab cov neeg muag khoom nyiam, tab sis txoj haujlwm zoo ib yam. Ib yam khoom sib xws tab sis txawv yog qhovfiber pigtail, uas muaj ib tug connector ntawm tsuas yog ib kawg thiab feem ntau yog spliced rau lub cev cable es tsis siv rau tshem tawm kev sib txuas.
Yuav Ua Li Cas Xaiv Txoj Cai Fiber Jumper
Xaiv txoj cai jumper ua ntej koj qhib lub hnab tiv thaiv qhov kev ua yuam kev ntau tshaj plaws. Muaj plaub qhov kev txiav txim siab los ua: hom connector, fiber ntau, cable siv, thiab ntev.
Sib phim hom Connector rau qhov chaw nres nkoj
Xyuas lub cev interface ntawm ob qho kawg. Yog tias cov cuab yeej siv LC ports, siv ib qhoLC fiber ntau jumper. Yog tias sab vaj huam sib luag yog SC, siv ib qhoSC daim kab xev. Tsis txhob yuam tus connector rau hauv lub adapter tsis sib haum - nws yuav zaum ib nrab tab sis yuav ua rau poob thiab pheej hmoo ua rau lub ferrule los yog qhov chaw nres nkoj.
Hauv qhov chaw siab -cov ntaub ntawv ceev ceev, LC yog qhov tseem ceeb vim nws qhov me me. SC thiab FC tseem muaj nyob rau hauv cov khoom siv hauv xov tooj thiab cov cuab yeej cuab tam. Rau siab -fiber- suav kev sib txuas ntawm lub cev,MPO / MTP connectorsyog tus qauv zuj zus.
Kuj xyuam xim rau covconnector polish hom - PC, UPC, lossis APC. APC connector (lub cev sib tiv tauj, feem ntau nrog lub khau raj ntsuab ntsuab) yuav tsum sib koom nrog lwm tus APC txuas. Txuas APC rau UPC ua rau poob siab rov qab thiab tsis zoo lub teeb liab. Qhov no yog ib qho ntawm feem ntau saib tsis sib haum xeeb hauv kev teeb tsa.
Tib -Mode vs Multimode: Sib piv hom Fiber rau qhov txuas
Lub jumper hom fiber ntau yuav tsum phim cov kab ke uas nws txuas nrog. Atib - hom fiber ntaujumper ntawm qhov txuas multimode - lossis vice versa - ua rau muaj kev cuam tshuam loj heev thiab tsis muaj kev ntseeg siab. Cov tub ntxhais txoj kab uas hla tsis sib haum ib leeg tuaj yeem ua rau ntau dB poob ntawm txhua qhov kev sib txuas.
Kev kuaj pom sai sai pab: ib leeg- hom kab cords feem ntau siv cov tsho daj nrog xiav lossis ntsuab khau looj plab hlaub, thaum cov hlua multimode yog txiv kab ntxwv (OM1/OM2) lossis aqua (OM3/OM4). Txawm li cas los xij, ib txwm txheeb xyuas cov cim cable es tsis yog cia siab rau xim ib leeg, tshwj xeeb tshaj yog nrog cov tsis yog - cov neeg muag khoom tus qauv.
