Kuti zvive nechokwadi chekuti mashandisirwo emasaini ekufambisa maoptical ari kure uye ari pasi pesimba, tambo yefiber optic inofanira kusangana nemamiriro ezvinhu chaiwo ekunze. Chero kukanganiswa kudiki kana kusvibiswa kwetambo dzeoptical kunogona kukonzera kudzikira kwemasaini eoptical uye kutokanganisa kutaurirana.
1. Kureba kwemutsetse wekufambisa tambo yefiber optic
Nekuda kwehunhu hwetambo dze optical uye kusaenzana kwekugadzirwa, masaini e optical anoparadzirwa maari anogara achipararira uye achinyudzwa. Kana fiber optic cable link yareba zvakanyanya, zvichaita kuti kudzikira kwese kwechiratidzo che optical che link yese kupfuure zvinodiwa pakuronga network. Kana kudzikira kwechiratidzo che optical kwakakura zvakanyanya, kunoderedza mhedzisiro yekutaurirana.
2. Kona yekukombama yekuisa tambo ye optical yakakura zvakanyanya
Kudzikira kwekukombama uye kudzikira kwekumanikidzwa kwetambo dzeoptical zvinonyanya kukonzerwa nekuchinjwa kwetambo dzeoptical, izvo zvinoita kuti isakwanise kugutsa kuratidzwa kwese panguva yekushandiswa kwe optical transmission. Tambo dzeoptical dzine mwero wakati wekukombama, asi kana tambo yeoptical yakakotama kune imwe kona, inokonzera shanduko munzira yekupararira kwechiratidzo cheoptical mutambo, zvichikonzera kudzikira kwekukombama. Izvi zvinoda kutarisisa zvakanyanya pakusiya maangle akakwana ekubatanidza waya panguva yekuvaka.
3. Tambo ye fiber optic inomanikidzwa kana kutyoka
Uku ndiko kukanganisa kunowanzoitika kana tambo dzemagetsi dzichikundikana kushanda. Nekuda kwemasimba ekunze kana njodzi dzechisikigo, tambo dzemagetsi dzinogona kusangana nekukombama kudiki kusina kurongeka kana kutotyoka. Kana tambo dzemagetsi dzikatyoka mukati mebhokisi re splice kana tambo dzemagetsi, hadzigone kuonekwa kubva kunze. Zvisinei, panosvika tambo dzemagetsi dzinotyoka, pachava nekuchinja kwe refractive index, uye kunyange kurasikirwa ne reflection, izvo zvinoderedza kunaka kwechiratidzo chinotumirwa chetambo. Panguva ino, shandisa OTDR optical cable tester kuti uone reflection peak uye uwane internal bending attenuation kana fracture point yetambo dzemagetsi.
4. Kukundikana kwekubatanidza majoini e fiber optic
Mukuita kwekuisa tambo dze optical, fiber fusion splicers dzinowanzo shandiswa kubatanidza zvikamu zviviri zve optical fibers kuita chimwe. Nekuda kwekubatanidzwa kwegirazi fiber muchikamu chikuru che optical cable, zvakakosha kushandisa fusion splicer nemazvo zvichienderana nerudzi rwe optical cable panguva yekuvaka fusion splicing process. Nekuda kwekushanda kusingatevedzere zvinodiwa pakuvaka uye shanduko munzvimbo yekuvaka, zviri nyore kuti optical fiber ive netsvina, zvichikonzera kusvibiswa kwakasanganiswa panguva yekubatanidzwa kwe fusion uye zvichikonzera kudzikira kwehunhu hwekutaurirana kwe link yese.
5. Dhayamita yewaya yepakati pefayibha inosiyana
Kuisa tambo dzefiber optic kunowanzo shandisa nzira dzakasiyana-siyana dzekubatanidza, dzakadai sekubatanidza maflange, izvo zvinowanzoshandiswa mukuisa network yemakombiyuta muzvivakwa. Kubatanidza kunoshanda kunowanzova nekurasikirwa kushoma, asi kana kumeso kwefiber ye optical kana flange kusina kuchena panguva yekubatanidza kunoshanda, dhayamita yefiber ye optical yakasiyana, uye joint isina kusimba, zvichawedzera zvakanyanya kurasikirwa kwejoint. Kuburikidza neOTDR kana dual end power testing, zvikanganiso zve core diameter zvinogona kuonekwa. Zvinofanira kucherechedzwa kuti single-mode fiber ne multi-mode fiber zvine nzira dzakasiyana dzekutumira, wavelengths, uye nzira dzeattenuation kunze kwedhayamita yefiber ye core, saka hazvigone kusanganiswa.
6. Kusvibiswa kwechinobatanidza chefiber optic
Kusvibiswa kwemajoini efiber yemuswe uye hunyoro hwefiber skipping ndizvo zvinonyanya kukonzera kutadza kushanda kwetambo dze optical. Kunyanya muma network emukati, kune ma short fiber akawanda uye akasiyana-siyana ma network switching devices, uye kuiswa nekubvisa fiber optic connectors, kutsiva flange, uye switching zvinoitika kakawanda. Munguva yekushanda, guruva rakawandisa, kurasikirwa nekuisa uye kubvisa, uye kubata minwe zvinogona kuita kuti fiber optic connector ive yakasviba zviri nyore, zvichikonzera kutadza kugadzirisa nzira ye optical kana kuderedza chiedza zvakanyanya. Alcohol swabs dzinofanira kushandiswa pakuchenesa.
7. Kusanyatso polishwa zvakanaka pajoini
Kusanyatso polishwa kwemajoini ndeimwe yezvikanganiso zvikuru mu fiber optic links. Hapana nzvimbo yakakwana ye fiber optic cross-section munzvimbo chaiyo, uye pane mamwe ma undulations kana slopes. Kana chiedza chiri mu optical cable link chikasangana ne cross-section yakadaro, nzvimbo isina kurongeka yejoini inokonzera kupararira kwe diffuse uye kuratidzwa kwechiedza, izvo zvinowedzera zvakanyanya attenuation yechiedza. Pa curve ye OTDR tester, attenuation zone yechikamu chisina kupolishwa zvakanaka yakakura kupfuura iyo ye foreground face yakajairika.
Zvikanganiso zvine chekuita nefiber optic ndizvo zvinonyanya kuoneka uye zvinowanzo itika panguva yekugadzirisa kana kugadzirisa. Saka, mudziyo unodiwa kuti utarise kana kubuda kwechiedza chefiber optic kwakajairika. Izvi zvinoda kushandiswa kwezvishandiso zvekuongorora fault yefiber optic, zvakaita se optical power metres nemared light pens. Optical power metres inoshandiswa kuyedza kurasikirwa kwefiber optic transmission uye zviri nyore kushandisa, zviri nyore, uye zviri nyore kushandisa, zvichiita kuti ive sarudzo yakanakisa yekugadzirisa faults yefiber optic. Red light pen inoshandiswa kuwana kuti fiber optic disc ipi iri pafiber optic. Izvi zvishandiso zviviri zvakakosha zvekugadzirisa faults dzefiber optic, asi ikozvino optical power meter nered light pen zvabatanidzwa kuita mudziyo mumwe chete, izvo zviri nyore.
