Ib Daim Ntawv Ceev Qhia Rau Fiber Optic Fais Meter
Thaum koj nruab thiab tshem cov kab mob fiber ntau, koj yuav tsum sim lawv. Ib qho kev kuaj yuav tsum tau ua rau txhua lub fiber optic cable cog rau peb lub ntsiab qhov tseem ceeb: kev sib txuas, kev poob, thiab lub zog. Thiab lub tshuab fais fab fais fab yog ib feem ntawm cov cuab yeej lub hauv paus los ua qhov no. Muaj ntau hom kev siv fais fab, cov tshuab ib nrab xwb, thiab cov fais fab ntsuas qhov nruab nrab ntawm lub hom phiaj, xws li FTTx lossis LAN / WAN architectures. Nws yog txhua yam teeb meem ntawm kev xaiv txoj cai iav rau qhov kev xav tau.
Ntawm no yog ib daim ntawv qhia ceev txog fiber ntau optic meters thiab seb lawv ua haujlwm li cas.
Optical fais fab tuag feem ntau yog siv los ntsuas qhov pom lub hwj chim hauv dBm. Rau kev ntsuas dBm ntawm lub teeb kis mus rau lub teeb, kev kho kom zoo yog qhov tseem ceeb. Lub tshuab fais fab fiber optic tseem siv nrog lub teeb ci qhov muag rau kev ntsuas poob lossis sib txheeb ze zog hauv dB. Los xam lub hwj huam, optic fais fab tuag yog thawj zaug txuas ncaj qha mus rau qhov kev sib kis tau kho ntawm lub tshuab pigtail, thiab ntsuas lub zog. Tom qab ntawd cov kev ntsuas raug muab tshem tawm ntawm qhov kawg ntawm cov fibre cable.
Fiber optic hluav taws xob ntsuas ntsuas lub zog nruab nrab ntawm ib lub teeb nruam ntawm lub teeb nyob rau hauv ib lub tshuab fiber ntau qhov muag, kuaj lub teeb liab ntawm lub laser lossis lub teeb emitting diode (LED) qhov chaw. Lub teeb dispersion tuaj yeem tshwm sim nyob rau ntau lub ntsiab lus hauv lub network vim kev ua yuam kev lossis kev ua yuam kev; lub hwj chim ntsuas ntsuas cov qib high-powered beams ntawm ntev-nrug ib hom fibers thiab tsawg-zog multibeams ntawm luv-nruas multimode fibers.
Tej yam tseem ceeb tshwj xeeb rau fiber ntau fais fab metres muaj xws li wavelength ntau, optical power ntau, hwj huam daws teeb meem, thiab muaj hwj chim. Qee cov khoom siv khib nyiab lossis tuav tes. Lwm tus yog tsim los siv atop ib lub rooj zaum los yog desktop. Fais fab ntsuas uas txuas rau cov computers kuj muaj.
Lub fais fab fiber optic yog lub ntsuas me me tshwj xeeb uas ntsuas ntau npaum li cas lub teeb tuaj tawm ntawm qhov kawg ntawm fiber ntau optic cable. Lub hwj chim ntsuas yuav tsum ntsuas tau lub teeb ntawm lub qhov ntsuas ntawm qhov zoo thiab muaj zog txaus. Feem ntau cov kev siv fais fab siv hauv cov hauj lwm datacom yog tsim los ua haujlwm ntawm 850nm thiab 1300nn. Cov hwj huam ntau yog txaj muag, nyob rau hauv thaj tsam ntawm -15 mus rau-35dBm rau kev sib txuas hauv kev sib txuas, 0 rau-40dBm rau ib hom kev sib txuas. Fais fab ntsuas feem ntau tau yoog rau ntau hom kev sib txuas xws li SC, ST, FC, SMA, LC, MU, lwm yam.
Feem ntau, cov tshuab fiber ntau yog kuaj nrog LEDs ntawm ob qho tib si 850nm thiab 1300nm thiab ib hom fiber ntau yog kuaj nrog lasers ntawm 1310nm thiab 1550nm. Qhov kev kuaj seb qhov twg yuav yog ib qho LED rau ntau hom fiber ntau tshwj tsis yog siv fiber ntau rau Gigabit Ethernet lossis lwm lub network uas siv cov chaw laser. LEDs yuav raug siv los kuaj tib hom fibers tsawg dua 5000 mais ntev, thaum lub laser yuav tsum tau siv rau ntev tib hom fibers.
Feem ntau cov fib ntiv taw fib fab feem ntau yog ntsuas hauv cov kab tawm ncaj qha xws li nationalwatts lossis microwatts. Lawv kuj tseem yuav muab cov kev ntsuas hauv cov decibels uas hais txog ib lub teb chaws los yog microwat ntawm qhov muag fais fab. Feem ntau, fiber optic fais fab tuag muaj xws li ib tug tshem tawm adapter rau kev sib txuas rau lwm yam khoom siv. Los ntawm ntsuas nruab nrab lub sij hawm es tsis txhob ncov hwj chim, lub hwj chim ntsuas tau nyob twj ywm rau lub voj voog ua haujlwm ntawm cov teeb meem digital pulse.
Siv cov fais fab fiber optic thiab lwm yam khoom siv fiber ntau optic cuab tam kom paub tseeb tias koj qhov system fiber optic yuav ua hauj lwm ntseeg nkaws.
