Polymer Optical fiber (POF) ndeyeOptical Fiber inoumbwa nepamusoro refractive index polymer zvinhu sefiber musimboti uye yakaderera refractive index polymer zvinhu sekupfeka. Kufanana neiyo quartz optical fiber, iyo plastiki optical fiber inoshandisawo iyo yakazara ratidziro musimboti wechiedza. Iyo optical faibha musimboti irenje dense yepakati uye iyo yekupfekedza ndeye yakareruka dense yepakati. Nenzira iyi, chero bedzi kona yechiedza inopinda yakakodzera, bhanhire rechiedza richaratidzwa nguva dzose mukati me optical fiber uye rinoendeswa kune rumwe rutivi.
Zvakanakira zvepurasitiki optical fiber
Optical fiber communication ine zvitatu zvakanakira pamusoro pemagetsi echinyakare (copper) cable communication: chekutanga, huru yekutaurirana kugona; Chechipiri, ine yakanaka anti electromagnetic kupindira uye kuvanzika kuita; Chechitatu, ine uremu hwakareba uye inogona kuchengetedza mhangura yakawanda. Semuenzaniso, kuisa tambo ye 1000 km kureba 8-core optical cable inogona kuchengetedza matani zana negumi emhangura uye matani mazana matatu nemakumi manomwe emutobvu pane kuisa 8-core tambo yehurefu hwakafanana. Naizvozvo, kana iyo optical fiber uye optical cable yabuda, yakagamuchirwa neindasitiri yekukurukurirana, iyo yakaunza shanduko mundima yekukurukurirana uye kutenderera kwekudyara uye kusimudzira kusimudzira. Kunyange zvazvo quartz (girazi) optical fiber ine zvakanakira zvataurwa pamusoro apa, ine kushaya simba kunouraya: kuderera kwesimba, kushomeka kwemaitiro ekudzivirira uye kushomeka kwemwaranzi.
Kuenzaniswa nequartz optical fiber, plastiki optical fiber chimwe chezvinhu zveindasitiri yeruzivo zvine kukosha kwekutsvagisa uye tarisiro yekushandisa mumunda wePolymer Science mumakore makumi maviri achangopfuura. Ine zvinotevera maitiro:
(1) Iyo dhayamita yakakura, kazhinji inosvika 0.5 ~ 1mm. Iyo hombe fiber musimboti inoita kuti kubatana kwayo kuve nyore uye nyore kurongedza, kuitira kuti yakachipa jekiseni rekuumba majoini anogona kushandiswa uye mari yekuisa yakaderera kwazvo;
( 2) Nhamba yenhamba (NA) yakakura, inenge 0.3 ~ 0.5, uye kushanda kwekubatanidza nechiedza uye chigadziro chekugamuchira chakakwirira;
( 3) Iyo yekushandisa modhi ine zvakanakira zvezvakachipa zvekushandisa, yakaderera mutengo wekugadzira uye yakafara kushandiswa.
