Pali mitundu ingapo ya ulusi wa kuwala

Ulusi wa Optical ndi gawo lofunikira la njira zamakono zolumikizirana komanso kutumiza deta. Amagwiritsidwa ntchito potumiza ma siginecha owoneka pamtunda wautali ndikutaya pang'ono mphamvu yazizindikiro. Pali mitundu yambiri ya fiber optics, iliyonse ili ndi mawonekedwe akeake komanso ntchito zake.

1. Single-mode Optical fiber: Makulidwe apakati a single-mode Optical fiber ndi ochepa, nthawi zambiri amakhala pafupifupi 9 microns. Zapangidwa kuti zizinyamula njira imodzi ya kuwala, zomwe zimathandiza kuti bandwidth yapamwamba komanso kutumizira mtunda wautali. Ulusi wamtundu umodzi umagwiritsidwa ntchito kwambiri pamalumikizidwe akutali komanso ma data othamanga kwambiri.

2. Multimode kuwala CHIKWANGWANI: Pakatikati awiri a multimode kuwala CHIKWANGWANI ndi yaikulu, kawirikawiri kuzungulira 50 kapena 62.5 microns. Amatha kunyamula mitundu ingapo ya kuwala, kulola kutsika kwa bandwidth ndi mtunda waufupi wotumizira kuposa ulusi wamtundu umodzi. Multimode fiber imagwiritsidwa ntchito kwambiri pamapulogalamu apatali ngati ma network amderali (LANs) ndi ma data center.

3. Pulasitiki optical fiber (POF): POF imapangidwa ndi zipangizo zapulasitiki monga polymethylmethacrylate (PMMA). Ili ndi mainchesi okulirapo ndipo imatha kusinthasintha kuposa fiberglass, zomwe zimapangitsa kuti ikhale yosavuta kuyiyika ndikugwira. POF imagwiritsidwa ntchito kwambiri pamagetsi ogula, ntchito zamagalimoto ndi ma network akunyumba.

4. gradient index fiber: Refractive index of the graded index fiber core pang'onopang'ono imachepa kuchokera pakatikati mpaka kunja. Kapangidwe kameneka kamathandizira kuchepetsa kufalikira kwa ma modal poyerekeza ndi fiber multimode, kulola bandwidth yapamwamba komanso mtunda wautali wotumizira.

5. Polarization Kusunga Ulusi: Mtundu uwu wa ulusi umapangidwa kuti ukhalebe ndi polarization ya kuwala pamene ukuyenda mu ulusi. Nthawi zambiri amagwiritsidwa ntchito m'mapulogalamu omwe kusunga kuwala kwa polarization ndikofunikira, monga ma fiber optic sensors ndi interferometric systems.

Mtundu uliwonse wa ulusi uli ndi zabwino zake ndi zolephera zake, ndipo kusankha mtundu woyenera kumatengera zofunikira zomwe zimagwiritsidwa ntchito. Pamene luso lamakono likupitilila patsogolo, mitundu yatsopano ya ma optical fibers ikupangidwa kuti ikwaniritse kufunika kokulirapo kwa maukonde othamanga kwambiri, othamanga kwambiri. Kumvetsetsa mawonekedwe a mitundu yosiyanasiyana ya ulusi wa optical ndikofunikira kuti apange ndikukhazikitsa njira zolumikizirana zowoneka bwino komanso zodalirika.
