An optical fiber ndeye inochinjika, yakajeka faibha yakagadzirwa neextrud girazi kana epurasitiki, yakakora zvishoma kupfuura bvudzi remunhu.Optical fibers anoshandiswa kazhinji senzira yekufambisa mwenje pakati pemigumo miviri yefayibha uye kuwana kushandiswa kwakakura mufiber-optic communications, kwavanobvumidza kutapurirana madaro marefu uye pakakwirira bandwidths kupfuura waya waya.Optical fibers anowanzo sanganisira yakajeka musimboti wakakomberedzwa neyakajeka yekupfeka zvinhu ine yakaderera indekisi yerefraction.Chiedza chinochengetwa muhupamhi nechiitiko chekuratidzira kwemukati kwese kunoita kuti fiber iite senge waveguide.Kazhinji, kune marudzi maviri efiber optical: fiber inotsigira nzira dzakawanda dzekuparadzira kana nzira dzakachinjika dzinodaidzwa kuti multimode fibers (MMF), nepo idzo dzinotsigira imwe modhi dzinonzi single mode fibers (SMF).Single mode vs multimode fiber: chii chakasiyana pakati pavo?Kuverenga chinyorwa ichi kuchakubatsira kuwana mhinduro.
Single Mode vs Multimode Fiber: Chii chinonzi single mode optical fiber?
Mu fiber-optic communication, single mode optical fiber (SM) is an optical fiber yakagadzirirwa kutakura chiedza chete zvakananga pasi pasi fiber - the transverse mode.Kune imwechete mode optical fiber, zvisinei kuti inoshanda pa100 Mbit/s kana 1 Gbit/s date rates, kureba kwekufambisa kunogona kusvika kunosvika 5 km.Kazhinji, inoshandiswa pakufambisa kwemasaini kureba.
Single Mode vs Multimode Fiber: Chii chinonzi multimode optical fiber?
Multimode optical fiber (MM) imhando yeoptical fiber inonyanya kushandiswa kutaurirana pamusoro pezvinhambwe zvipfupi, senge mukati mechivako kana pakambasi.Mafambiro ekutakurisa uye nhambwe inosvika 100 Mbit/s yezvinhambwe zvinosvika 2 km (100BASE-FX), 1 Gbit/s kusvika 1000m, uye 10 Gbit/s kusvika 550 m.Kune marudzi maviri emultimode indexes: nhanho index uye graded index.
Ndeupi musiyano pakati pe single mode optical fiber uye multimode?
Attenuation: Iyo attenuation ye multimode fiber yakakwira kupfuura SM fiber nekuda kweiyo yakakura dhayamita yepakati.Iyo fiber core ye single mode tambo yakatetepa, saka mwenje unopfuura neaya mafiber optical tambo haaratidzike kakawanda, izvo zvinoita kuti kudzikama kuve kushoma.
| Single Mode Fiber | Multimode Fiber | ||
| Attenuation pa1310nm | 0.36dB/km | Attenuation pa850nm | 3.0dB/km |
| Attenuation pa1550nm | 0.22dB/km | Attenuation pa1300nm | 1.0dB/km |
Core dhayamita:Musiyano mukuru pakati pemultimode uye single mode fiber ndeyekuti yekutanga ine yakakura dhayamita yepakati, kazhinji ine dhayamita yepakati ye50 kana 62.5 µm uye dhayamita yekuvhara ye125 µm.Nepo imwe chete modhi faibha ine dhayamita yepakati pakati pe8 ne10 µm uye dhayamita yekuvhara ye125 µm.
Bandwidth
Sezvo multimode faibha ine hombe yepakati-saizi pane imwechete mode fiber, inotsigira anopfuura imwe nzira yekuparadzira.Kunze kwezvo, kufanana nemultimode fibers, single-mode fibers inoratidza modal dispersion inokonzerwa nemhando dzakawanda dzenzvimbo, asi modal dispersion ye single mode fiber ishoma pane multi-mode fiber.Nekuda kwezvikonzero izvi, single mode fibers inogona kuve yakakwira bandwidth kupfuura akawanda-modhi fibers.

Rudzi rwejaketi dzimwe nguva rinoshandiswa kusiyanisa tambo dzemultimode kubva kune imwechete mode.Iyo yakajairwa TIA-598C inokurudzira, kune zvisiri zvechiuto zvikumbiro, kushandiswa kwejaketi reyero kune imwechete mode fiber, uye orenji kana aqua kune multimode fiber, zvichienderana nerudzi.Vamwe vatengesi vanoshandisa violet kusiyanisa yakakwirira performance OM4 communications fiber kubva kune mamwe marudzi.
