Ka Pono o ka Plastic Optic Fiber

2022-04-15

Polymer Optical fiber (POF) he Optical Fiber i haku ʻia me ke kiʻekiʻe refractive index polymer material like fiber core and low refractive index polymer material like cladding. E like me ka quartz optical fiber, hoʻohana ka plastic optical fiber i ke kumu hoʻohālike holoʻokoʻa o ka mālamalama. ʻO ke kumu o ka fiber optical he mea māmā māmā a ʻo ka pale ʻana he māmā māmā. Ma kēia ala, ʻoiai ka lōʻihi o ke komo ʻana o ke kukui i kūpono, e ʻike mau ʻia ke kukui o ke kukui i loko o ka fiber optical a hoʻouna ʻia i kekahi ʻaoʻao.

ʻO nā pono o ka fiber optical plastic

ʻEkolu mau mea maikaʻi ma mua o ke kelepona uila (keleawe) maʻamau: ʻo ka mua, ka hiki ke kamaʻilio nui; ʻO ka lua, loaʻa iā ia ka hana anti electromagnetic maikaʻi a me ka hana huna; ʻO ke kolu, he māmā ke kaumaha a hiki ke mālama i ka nui o ke keleawe. No ka laʻana, ʻo ka waiho ʻana i 1000 km lōʻihi 8-core optical cable hiki ke mālama i 1100 tons keleawe a me 3700 tons of lead ma mua o ka waiho ʻana i kahi kaula 8-core o ka lōʻihi like. No laila, i ka manawa i puka mai ai ka fiber optical a me ke kaula optical, ua hoʻokipa ʻia e ka ʻoihana kamaʻilio, i lawe mai i kahi kipi i ke kahua kamaʻilio a me kahi pōʻai o ka hoʻopukapuka kālā a me ka ulu ʻana. ʻOiai ua loaʻa i ka quartz (aniani) nā mea maikaʻi i ʻōlelo ʻia ma luna nei, he nāwaliwali kona: haʻahaʻa ikaika, haʻahaʻa haʻahaʻa haʻahaʻa a me ka pale ʻana i ka radiation.

Ke hoʻohālikelike ʻia me ka quartz optical fiber, plastic optical fiber kekahi o nā mea no ka ʻoihana ʻike me ka manaʻo noiʻi noiʻi koʻikoʻi a me nā manaʻo noiʻi ma ke kahua o Polymer Science i nā makahiki 20 i hala iho nei. Loaʻa iā ia nā hiʻohiʻona penei:

(1) Nui ke anawaena, maʻamau a hiki i 0.5 ~ 1mm. ʻO ke kumu fiber nui e maʻalahi kona pilina a maʻalahi hoʻi e align, no laila hiki ke hoʻohana ʻia nā mea hoʻopili hoʻoheheʻe ʻia a haʻahaʻa loa ke kumukūʻai hoʻokomo;

(2) He nui ka puka helu (NA), ma kahi o 0.3 ~ 0.5, a he kiʻekiʻe ka maikaʻi o ka hoʻohui ʻana me ke kumu kukui a me ka mea hoʻokipa;

(3) Loaʻa i ke kumu hoʻohālike nā pono o nā mea liʻiliʻi, nā kumu kūʻai haʻahaʻa haʻahaʻa a me ka noi ākea.
