Intera yoherejwe ya fibre yuburyo bumwe: 64-imiyoboro ya 40G ya Ethernet irashobora kuba ndende nkibirometero 2.840 kumurongo umwe.Ubwoko bumwe bwa fibre igizwe ahanini nibyingenzi, igipfundikizo hamwe nigitambaro cyo gutwikira. Intangiriro ikozwe mubintu bisobanutse cyane. Kwambika imyenda bifite indangantego yoroheje gato ugereranije nibyingenzi, bikavamo ingaruka nziza ya optique yemerera benshi y'umurima wa electromagnetique ugomba gufatirwa mu nsi. Igipfundikizo gikora mu kurinda Fibre irinda ubushuhe no gukanika imashini, mu gihe byongera ubworoherane bwa fibre.Hanze yo gutwikira, ikoti rya plastike ryongeweho.
Ni irihe tandukaniro riri hagati ya fibre yuburyo bumwe na fibre ya multimode?
Itandukaniro mubyerekana byangiritse: Fibre imwe-imwe ikoresha intambwe yerekana intambwe.Fibre ya Multimode irashobora gukoresha intambwe yerekana intambwe cyangwa ibipimo byerekana amanota.Niyo mpamvu, fibre ya quartz irashobora kandi gukoresha muri rusange fibre yintambwe yintambwe, fibre yerekana indangagaciro, hamwe nuburyo bumwe bwerekana intambwe.Ubwoko butatu.
Itandukaniro muburyo bwo kohereza: fibre yuburyo bumwe irashobora kohereza gusa uburyo bumwe kuburebure bwatanzwe bwo gukora, kandi fibre fibre irashobora kwanduza uburyo bwinshi. Ikwirakwizwa ryumuriro wa electromagnetique muri fibre optique ni iry'umuzenguruko wa dielectric.Iyo urumuri ruba. bigaragarira rwose muburyo bwimikorere, imiyoboro ya electromagnetique igarukira hagati, ibyo bita kuyobora umurongo cyangwa kuyobora.Kubisobanuro byatanzwe byerekanwe hamwe nuburebure bwumurongo, haribintu bitandukanye byabaye byujuje ibisabwa byo kugaragariza hamwe, byitwa uburyo butandukanye bwo kuyobora imiraba.Igabanijwemo fibre ya multimode na fibre imwe ya fibre muburyo bwo kohereza.
Itandukaniro mu ntera yoherejwe: intera yohereza no gukwirakwiza umurongo wa fibre imwe ya fibre biragaragara ko biterwa na fibre ya multimode.Niba intera yoherejwe irenze kilometero 5, ibimenyetso binini byerekana amakuru yoherejwe mugihe kirekire kugirango uhitemo fibre imwe-imwe. Niba intera yoherejwe ari kilometero nkeya gusa, uburyo bwinshi nuburyo bwiza kuko LED transmitter / yakira bisaba urumuri rwa laser kuruta uburyo bumwe.Nibihendutse cyane.
Itandukaniro ryuburebure bwikwirakwizwa rya fibre: fibre imwe-fibre ifite diameter ntoya kandi irashobora kwanduzwa gusa muburyo bumwe kumurongo wogukora, hamwe numuyoboro mwinshi hamwe nubushobozi bunini bwo kohereza.Fibre fibre ni fibre optique ishobora kwanduza icyarimwe muburyo bwinshi kumurongo wateganijwe.Multimode fibre ifite imikorere idahwitse kuruta fibre imwe.
