I-Polymer Optical fiber (POF) iyi-Optical Fiber eyakhiwe ngezinto ezisezingeni eliphezulu ze-polymer ezinenkomba njenge-fiber core kanye ne-low refractive index polymer material njenge-cladding. Njenge-quartz optical fiber, i-plastic optical fiber nayo isebenzisa isimiso esiphelele sokubonisa ukukhanya. I-optical fibre core iwumphakathi ominyene okhanyayo futhi ukuvala kuyindawo ecinene ekhanyayo. Ngale ndlela, inqobo nje uma i-engeli yokungena yokukhanya ifanelekile, i-beam yokukhanya izobonakala ngokuqhubekayo ngaphakathi kwe-fiber optical futhi idluliselwe komunye umkhawulo.
Izinzuzo ze-plastic optical fiber
Ukuxhumana kwe-fiber optical kunezinzuzo ezintathu ngaphezu kokuxhumana kwezintambo zikagesi (zethusi) zendabuko: okokuqala, umthamo omkhulu wokuxhumana; Okwesibili, inokuphazamiseka okuhle kwe-anti electromagnetic nokusebenza okuyimfihlo; Okwesithathu, inesisindo esincane futhi ingonga ithusi eliningi. Isibonelo, ukubeka ikhebula le-8-core optical engu-1000 km ubude kungakonga amathani angu-1100 ethusi namathani angu-3700 omthofu kunokubeka intambo engu-8-core yobude obufanayo. Ngakho-ke, lapho i-fiber optical kanye nentambo ye-optical iphuma, yamukelwa imboni yezokuxhumana, eyaletha uguquko emkhakheni wezokuxhumana kanye nomjikelezo wokutshalwa kwezimali kanye nokuthuthukiswa kokuthuthukiswa. Nakuba i-quartz (ingilazi) i-fiber optical inezinzuzo ezibalwe ngenhla, inobuthakathaka obubulalayo: amandla aphansi, ukumelana nokuguquguquka okubuthakathaka kanye nokungazweli kahle kwemisebe.
Uma kuqhathaniswa ne-quartz optical fiber, i-plastic optical fiber ingenye yezinto ezisetshenziswa embonini yolwazi ezinokubaluleka kocwaningo lwethiyori kanye namathemba okusebenza emkhakheni wePolymer Science eminyakeni engama-20 yakamuva. Inezici ezilandelayo:
(1) Ububanzi bukhulu, ngokuvamile bufika ku-0.5 ~ 1mm. I-fiber core enkulu yenza ukuxhumana kwayo kube lula futhi kulula ukuvumelanisa, ukuze izixhumi zokubumba umjovo ezishibhile zingasetshenziswa futhi izindleko zokufaka ziphansi kakhulu;
( 2) Indawo yokuvula izinombolo (NA) inkulu, cishe ngo-0.3 ~ 0.5, futhi ukusebenza kahle kokuhlanganisa nomthombo wokukhanya nedivayisi yokwamukela kuphezulu;
( 3) Imodeli yensiza inezinzuzo zezinto ezishibhile, izindleko zokukhiqiza eziphansi kanye nokusetshenziswa okubanzi.
