Iyo yakakosha chimiro che optical fiber kazhinji inoumbwa nekunze sheath, cladding, musimboti, uye mwenje sosi. Single-modhi faibha uye akawanda-modhi faibha ine misiyano inotevera:
Musiyano wemuvara weSheath: Mumashandisirwo anoshanda, iyo yekunze sheath ruvara rwefiber inogona kushandiswa kukurumidza kusiyanisa pakati pe-single-mode fiber uye yakawanda-modhi fiber. Zvinoenderana netsanangudzo yeTIA-598C yakajairwa, single-mode fiber OS1 uye OS2 vanotora yero rekunze bhachi, multi-modhi faibha OM1 uye OM2 vanotora orenji bhachi rekunze, uye OM3 neOM4 vanotora aqua bhuruu rekunze bhachi (mukushandiswa kusiri kwechiuto) .
Core dhayamita musiyano: Multi-mode fiber uye single-mode fiber ine musiyano wakakura mupakati dhayamita, iyo dhayamita yepakati ye-multi-mode fiber inowanzo 50 kana 62.5µm, uye dhayamita yepakati ye single-mode fiber i9µm. Tichitarisa mutsauko uyu, single-mode fiber inogona chete kutumira masaini masaini ane wavelength ye1310nm kana 1550nm pane yakamanikana yepakati dhayamita, asi mukana weiyo diki core ndeyekuti iyo optical chiratidzo inopararira ichitevedza mutsara wakatwasuka mune imwe-modhi. fiber, isina refraction, kupararira kudiki, uye yakakwirira bandwidth; Iyo yakawanda-modhi faibha musimboti wakafara, uye inokwanisa kuendesa akasiyana modhi pane yakapihwa yekushanda wavelength, asi panguva imwe chete, nekuti kune akawanda semazana emamodhi anotapurirwa mu-multi-mode fiber, kuparadzira nguva dzose uye. chiyero cheboka reimwe modhi yakasiyana, kuitira kuti bhendi upamhi hwefiber hutete, kupararira kwakakura, uye kurasikirwa kukuru.
Iyo yakajairwa cladding dhayamita yeakawanda optical fibers i125um, uye yakajairwa yekunze yekudzivirira layer dhayamita ndeye 245um, iyo isingasiyanise single-multi-mode.
Musiyano wemwenje sosi: mwenje sosi inowanzove nemhando mbiri dzelaser mwenje sosi uye LED mwenje sosi. Single-mode fiber inoshandisa laser light source, multi-mode fiber inoshandisa LED mwenje sosi.
Izvo zviri pamusoro apa kuenzanisa kwechimiro chekutanga che single-mode fiber uye multi-mode fiber yakaunzwa neShenzhen HDV.Phoelectron Technology LTD., kuburikidza nehuwandu hwemapoinzi matatu kuti utsanangure, uchitarisira kubatsira avo vanoshaya. Shenzhen HDV Phoelectron Technology LTD inonyanya kuve yakavakirwa pane zvigadzirwa zvekutaurirana zvekugadzirwa kwevagadziri, iko ikozvino kugadzirwa kwemidziyo inovhara:ONUseries, optical module series,OLTseries, transceiver series. Inogona kupa masevhisi akajairwa kune akasiyana mamiriro ezvido zvetiweki, unogamuchirwa kuti uuye kuzobvunza.
