MuPON (Passive Optical Network) network, kunyanya mukati mekuoma-kune-multipoint PON ODN (Optical Distribution Network) topology, kukurumidza kutarisa uye kuongororwa kwefiber kukanganisa kunopa matambudziko makuru. Kunyange zvazvo optical time domain reflectometers (OTDRs) ari maturusi anoshandiswa zvakanyanya, dzimwe nguva anoshaya kunzwisiswa kwakakwana kwekuona kuderedzwa kwechiratidzo muODN bazi fiber kana paONU fiber ends. Kuisa yakaderera-inodhura wavelength-selective fiber reflector padivi reONU itsika yakajairika inogonesa chaiyo yekupedzisira-kumagumo attenuation kuyerwa kwe optical links.
Iyo fiber reflector inoshanda nekushandisa optical fiber grating kuratidza iyo OTDR bvunzo kupuruzira kumashure neinosvika zana muzana kuratidza. Zvichakadaro, iyo yakajairwa yekushanda wavelength yeiyo passive optical network (PON) system inopfuura neinoratidzira ine kushoma attenuation nekuti haigutse iyo fiber grating's Bragg mamiriro. Basa rekutanga reiyi nzira ndeyekunyatso kuverenga kukosha kwekurasikirwa kwekudzoka kwega rega reONU bazi rekumisa chiitiko chekuratidzira nekuona kuvepo uye kusimba kweiyo inoratidzwa OTDR bvunzo chiratidzo. Izvi zvinogonesa kutsunga kwekuti chinongedzo chemaziso pakati peOLT neONU mativi chiri kushanda zvakajairika. Nekuda kweizvozvo, inowana chaiyo-nguva yekutarisa yekukanganisa mapoinzi uye nekukurumidza, kwakaringana diagnostics.
Nekuchinjika kuendesa zviratidziro kuti zvione zvikamu zvakasiyana zveODN, kukurumidza kuona, kugarisana, uye midzi yekuongorora kukanganisa kweODN inogona kuwanikwa, kuderedza nguva yekugadzirisa kukanganisa uku uchiwedzera kushanda zvakanaka kwekuyedza uye mhando yekugadzirisa mutsara. Mune yekutanga splitter mamiriro, mafiber reflectors akaiswa padivi reONU anoratidza nyaya kana bazi rinoratidzira richiratidza zvakanyanya kuwedzera kurasikirwa kwekudzoka zvichienzaniswa nekutanga kwayo ine hutano. Kana matavi ese efiber akashongedzerwa neanoratidza panguva imwe chete anoratidza akadudzwa kudzoka kurasikirwa, zvinoratidza kukanganisa muhunde huru.
Mune yechipiri splitter mamiriro, mutsauko mukurasikirwa kwekudzoka unogona zvakare kufananidzwa nekunongedza chaiko kana zvikanganiso zveattenuation zvichiitika muchikamu chefiber yekugovera kana yekudonha fiber segment. Zvingave zviri muzvikamu zvepuraimari kana zvechipiri zvakapatsanurwa, nekuda kwekudonha kusingayereki kwekutarisisa pamagumo eOTDR test curve, kukosha kwekurasikirwa kwekurebesa kwebazi rekubatanidza muODN network inogona kusayerwa chaizvo. Naizvozvo, shanduko muratidziro yekutarisisa mwero inofanira kuyerwa sehwaro hwekuyerwa kwekukanganisa uye kuongororwa.
Optical fiber reflectors inogonawo kuiswa panzvimbo dzinodiwa. Semuyenzaniso, kuisa FBG pamberi peFiber-to-the-Home (FTTH) kana Fiber-to-the-Building (FTTB) nzvimbo dzekupinda, wozoedza neOTDR, zvinobvumira kuenzaniswa kwedata rebvunzo richipesana nedata rekutanga kuona mukati / kunze kana kuvaka mukati / kunze fiber kukanganisa.
Fiber optic reflectors inogona kuiswa zviri nyore munhevedzano pamagumo emushandisi. Hupenyu hwavo hurefu, kuvimbika kwakagadzikana, hushoma tembiricha maitiro, uye nyore adapta yekubatanidza chimiro ndezvimwe zvezvikonzero ivo yakanakira Optical terminal sarudzo yeFTTx network link yekutarisa. Yiyuantong inopa FBG faibha optic zviratidziri mumhando dzakasiyana dzekurongedza, kusanganisira epurasitiki furemu maoko, simbi furemu maoko, uye pigtail mafomu ane SC kana LC majoini.
