Taw qhia ntawm Loopback Cable
Loopback Cable yog dab tsi?
Thaum kuaj cov khoom siv kis kab mob, cov khoom siv fiber ntau optic loopback feem ntau siv los ua cov cuab yeej ntsuas. Nws yog hu ua kev khiav hluav taws xob, cov ntaub ntawv digital, lossis ntws cov khoom rov qab mus rau lawv qhov chaw tsis tas ua haujlwm lossis hloov kho. Fiber optic loopback yog dav siv rau ntau yam ntawv. Hauv kev sib txuas lus ntawm kev sib txuas lus, loopback yog qhov kho vajtse lossis software txoj kev los noj ib lub cim tau txais los yog cov ntaub ntawv rov qab mus rau tus neeg xa ntawv. Nws yog qhov tseem ceeb heev rau kev daws cov teeb meem kev sib raug lub cev.Qhov no yuav ua ib daim ntawv qhia txog kev xaiv ib txoj cai loopback rau ib qho kev hloov hauv cov qhab nia.
Hom Fiber Optic Loopback
Li ntawd, dab tsi yog qhov fiber ntau optic loopback? Ua ntej yuav txiav txim siab uas siv cov kab laug sab los siv, peb yuav tsum xub paub cov qauv thiab kev faib tawm ntawm fiber ntau loopback cable.Kuv tshawb nrhiav cov teeb meem ntawm qhov muag khoom, fiber optic loopback muab ib qho yooj yim txoj kev ntsuam xyuas qhov kev ua tau zoo ntawm cov khoom siv kho qhov muag. Feem ntau, fiber optic loopback cable thiab fiber optic loopback module yog ob qho tib si fiber optic loopbacks. Fiber optic loopback cable yog cov kab hluav taws fiber optic loopback nrog kab pom. Nws muaj nruab nrog ob lub fais fab fiber optic connectors rau txhua qhov kawg ntawm lub cable. Thaum twg cov hlua sib dhos ua ke, txoj hlua kab yuav zoo li lub voj. Raws li rau fiber ntau optic loopback module, qhov loj tshaj qhov txawv yog tias nws muaj ib qhov thaiv kom tiv thaiv kab hauv. Thiab qhov looped qhov chaw txo rau kev pab yooj yim dua thiab cov pob nyiaj txiag.Qhov kev sib txuas ntawm hom loopback, fiber ntau loopback cables yuav muab faib rau LC, SC, FC, ST, MTP / MPO, E2000, thiab lwm yam. optic transceiver modules, feem ntau yog siv LC, SC thiab MTP / MPO loopback cables.
Xam 1: LC & SC Loopback Cable
LC thiab SC loopbacks yog tsim los nrog simplex fiber ntau cable thiab cov connectors; nws tsis yog yooj yim to taub lawv configurations. Raws li rau MTP / MPO loopback, nws yog siv los soj ntsuam tib seem kev sib tw, xws li 40G thiab 100G transceivers. Lub teeb nws txawv txij li cov xoob suav tsis yog ib txwm zoo tib yam hauv cov ntawv sib txawv.
8 Fibers MTP / MPO Loopback Cable Configuration
Nyob rau hauv 8 daim foos MTP / MPO loopback, yim fibers yog mus raws ob sab ntawm lub connector, tawm hauv central plaub raws npliag. Thiab cov fibers txais yuav ib txoj kev ncaj ncaj ntawm 1-12, 2-11, 5-8, 6-7. Txoj kev sib dhos sib dhos rau sab nraud yog qhia txog hauv daim duab nram qab no.
Xam 2: 8 Fibers Loopback Polarity Channel Cov Ncauj Lus
12 Fibers MTP / MPO Loopback Cable Configuration
Tsuas yog qhov txawv ntawm 12-fiber MTP loopback thiab 8-loopback loopback yog tias hauv nruab nrab plaub tog tsis khoob. Nws cov ntawv sib dhos yog 1-12, 2-11, 3-10, 4-9, 5-8, 6-7.
Daim Duab 3: 12 Fibers Loopback Polarity Channel Cov Ncauj Lus
24 Fibers MTP / MPO Loopback Cable Configuration
Tus 24 fibers MTP loopback kuj tau txais hom 1 polarity. Nws cov qauv kawm ua ke yog qhia hauv qab no.

Yuav siv Loopback Cable li cas?
Cov voj voog loopback feem ntau siv nrog kev soj ntsuam software rau "loop" tsheb txoj cai rov qab rau hauv qhov chaw nres nkoj. Yog tias cov ntaub ntawv xa tawm rau hauv lub loopback plug yog zoo tib yam rau cov ntaub ntawv tau txais los ntawm lub loopback plug, koj tuaj yeem xav tias cov kev sib txuas lus yooj yim ntawm qhov chaw nres nkoj ua haujlwm zoo. Li ntawd, daim ntawv thov ntawm loopback cable yog Loopback Test.
Loopback Test
Fiber loopback cable feem ntau yog siv los xyuas seb puas yuav tau txais qhov kev hloov pauv ntawm lub transceiver raws li tau tsim. Raws li peb txhua tus paub, tus tau txais kev pabcuam tau muaj ob qhov chaw nres nkoj, lub chaw nres nkoj ntawm chaw nres nkoj thiab lub chaw nres nkoj. Tus qub yog xa tawm laser teeb liab thiab qhov tom kawg yog los txais cov teeb meem. Thaum ua qhov kev xeem loopback, fiber ntau loopback cable tuaj yeem ncaj qha mus txuas rau qhov tso tawm thiab qhov chaw nres nkoj ntawm transceiver module feem (qhov chaw nres nkoj ntawm qhov xaus ntawm kev txuas yuav tsum tau tshaj). Yog li, thaum txoj kev xeem, lub loopback cable ncaj qha cov teeb meem laser ntawm lub chaw nres nkoj xa rov qab mus rau lub chaw nres nkoj txais khoom. Tom qab ntawd peb tuaj yeem sib piv cov qauv sib kis nrog cov qauv tau txais kev txhim kho qhov teeb meem hauv lub network. Fiber optic loopback kev soj ntsuam yog qhov yooj yim tshaj plaws los xyuas kom meej tias cov transceiver ua haujlwm tsis muaj tseeb. Thaum xaiv ib lub voj voos uas tsim nyog rau qhov kev hloov tsheb, peb yuav tsum xav txog lub hom sib txuas, hom roj txhuam, thiab hom xov tooj cua.
Daim ntawv thov
Thaum nws los txog rau daim ntawv thov, kev siv fiber ntau optic loopback feem ntau ua haujlwm rau kev kuaj cov fiber ntau optic zog. Vim hais tias muaj kev sib tshuam tau muaj ob qhov chaw nres nkoj rau kev txais thiab xa cov teeb liab, nws yog qhov yuav tsum kuaj qhov chaw nres nkoj seb lawv puas tseem ua haujlwm. Li no, fiber optic loopback xeem yog txoj kev yooj yim tshaj plaws rau kev hloov kho hauv tsev. Cov txheej txheem xeem yog los ntawm txoj kev teeb lub laser ntawm lub chaw xa khoom xa rov qab mus rau lub chaw nres nkoj. Ces tus kab mob kis tau muab piv rau tus qauv tau txais kom paub tseeb tias lawv zoo tib yam thiab tsis muaj qhov yuam kev.
