Muri rusange, hari ubwoko bubiri bwa fibre: izishyigikira inzira nyinshi zo gukwirakwiza cyangwa uburyo bwo guhinduranya bwitwa fibre-moderi fibre (MMF), naho izishyigikira uburyo bumwe zitwa fibre imwe (SMF). Ariko ni irihe tandukaniro riri hagati yabo? Gusoma iyi ngingo bizagufasha kubona igisubizo.
Incamake Yuburyo bumwe Vs Multimode Fibre Optic Cable
Ubwoko bumwe bwa fibre ituma ikwirakwizwa ryuburyo bumwe gusa icyarimwe, mugihe fibre optique ishobora gukwirakwiza uburyo bwinshi. Itandukaniro ryibanze hagati yabo riri muri fibre yibanze ya diameter, uburebure bwumucyo & isoko yumucyo, umurongo mugari, ibara ryamabara, intera, igiciro, nibindi.
Uburyo bumwe Vs Multimode Fibre, Itandukaniro Niki?
Igihe cyo kugereranya uburyo bumwe na multimodefibre optiquekandi wumve itandukaniro ryabo.
Diameter
Umugozi umwe wuburyo bumwe ufite ubunini buke, mubisanzwe 9μm, bigafasha kwiyegereza hasi, umurongo mwinshi, hamwe nintera ndende.
Ibinyuranye, fibre optique ya Multimode ifite ubunini bwibanze, mubisanzwe 62.5 mm cyangwa 50 mm, hamwe na OM1 kuri 62.5 mm na OM2 / OM3 / OM4 / OM5 kuri 5μm. Nubwo hari itandukaniro mubunini, ntabwo byoroshye kugaragara kuri eve yambaye ubusa kuko ari ntoya kuruta ubugari bwumusatsi wumuntu. Kugenzura kode yanditse kuri fibre optique irashobora gufasha kumenya ubwoko.
Hamwe nimyenda ikingira, uburyo bumwe hamwe na fibre fibre ifite diameter ya 125μm.
Umuhengeri & Umucyo Inkomoko
Multimode optique fibre, hamwe nubunini bwayo bwibanze, ikoresha urumuri ruhendutse rutanga urumuri rwa LEDs na VCSELs kuri 850nm na 1300nm yumurambararo. Ibinyuranyo, umugozi wuburyo bumwe hamwe nintoki zawo ntoya, ukoresha lazeri cyangwa diode ya laser kugirango ubyare urumuri rwinjijwe mumurongo, mubisanzwe muburebure bwa 1310nm na 1550nm.
Umuyoboro mugari
Ubu bwoko bubiri bwa fibre butandukanye mubushobozi bwumurongo. Ubwoko bumwe bwa fibre itanga umurongo utagira umupaka bitewe nubufasha bwawo butanga urumuri rumwe, bigatuma habaho kwiyegereza no gutatana. Nibihitamo guhitamo itumanaho ryihuta cyane kure.
Kurundi ruhande, fibre ya multimode irashobora kohereza uburyo bwinshi bwa optique, ariko ifite attenensiya nini kandi ikwirakwizwa ryinshi, bikagabanya umurongo wawo.
Ubwoko bumwe bwa fibre iruta fibre optique ya fibre mubushobozi bwumurongo.
Kwitonda
Fibre imwe-fibre ifite attenuation yo hasi, mugihe fibre fibre irashobora kwibasirwa cyane.
Intera
Uburyo bumwe bwa kabili yo hasi ya attenuation hamwe no gukwirakwiza uburyo butuma intera ndende ihererekanya kuruta multimode. Multimode irahendutse ariko igarukira kumurongo mugufi (urugero, 550m kuri 1Gbps), mugihe uburyo bumwe bukoreshwa mugukwirakwiza kure cyane.
Igiciro
Iyo urebye igiciro cyose, ibice bitatu bigira uruhare runini.
Igiciro cyo Kwinjiza
Igiciro cyo kwishyiriraho fibre-moderi imwe ikunze kugaragara ko iri hejuru ya kabili ya multimode kubera ibyiza byayo. Ariko, ikigaragara ni ikinyuranyo. dukesha gukora neza, kuzigama 20-30% ugereranije na fibre fibre. Kuri fibre nziza ya OM3 / OM4 / OM5, uburyo bumwe bushobora kuzigama kugera kuri 50% cyangwa birenga. Ariko, optique ya transceiver igiciro nayo igomba kwitabwaho.
Igiciro cyiza cya Transceiver
Amashanyarazi ya optique ni ikintu cyingenzi kigizwe na fibre cabling, ibara igice kinini, rimwe na rimwe igera kuri 70% yikiguzi cyose. Uburyo bumwe bwimikorere muri rusange bugura inshuro 1,2 kugeza kuri 6 kurenza imwe ya multimode. Ibi ni ukubera ko uburyo bumwe bukoresha imbaraga za laser diode (LD), zihenze cyane, mugihe ibikoresho byinshi bikoresha LED cyangwa VCSELS ihendutse.
Sisitemu yo kuzamura ibiciro
Hamwe niterambere ryihuse mubuhanga, sisitemu ya cabling akenshi isaba kuzamurwa no kwaguka. Ubwoko bumwe bwa fibre optique cabling itanga ubunini, guhinduka, no guhuza n'imiterere. Umugozi wa Multimode, bitewe numuyoboro mugari hamwe nubushobozi buke bwintera, birashobora guhatanira kuzuza ibyifuzo byigihe kizaza cyohereza intera ndende kandi nini cyane.
Kuzamura uburyo bumwe bwa fibre optique sisitemu iroroshye, irimo guhindura gusa switch na transcevers bitabaye ngombwa gushyira fibre nshya. Ibinyuranye, kuri kabili ya multimode, kuzamura kuva OM2 ukagera kuri OM3 hanyuma ukagera kuri OM4 kugirango byihute byihuta byatwara amafaranga menshi cyane, cyane cyane iyo uhinduye fibre yashyizwe munsi yubutaka.
Muncamake, multimode irahendutse kubirometero bigufi, mugihe uburyo bumwe nibyiza kubirometero bigera kure.
Ibara
Kode y'amabara yoroshya ubwoko bwa kabili. TlA-598C itanga inganda zerekana amabara kugirango tumenye byoroshye.
Multimode OM1 na OM2 mubisanzwe bafite ikoti rya orange.
OM3 mubusanzwe ifite ikoti ryamabara ya Aqua.
OM4 mubusanzwe ifite ikoti ryamabara ya Aqua cyangwa Violet.
OM5 yari ifite ibara ry'icyatsi kibisi.
Uburyo bumwe OS1 na OS2 mubisanzwe hamwe namakoti yumuhondo.
Gusaba
Umugozi wuburyo bumwe ukoreshwa cyane cyane murwego rurerure rwumugongo na sisitemu ya metero muri terefone, datacom, na CATV.
Kurundi ruhande, insinga ya multimode ikoreshwa cyane cyane mubikorwa bigufi bigereranywa nkibigo byamakuru, kubara ibicu, sisitemu yumutekano, hamwe na LANs (Local Area Networks).
Umwanzuro
Mu gusoza, uburyo bumwe bwa fibre cabling nibyiza kubwigihe kirekire cyohereza amakuru mumiyoboro yabatwara, MAN, na PONs. Multimode fibre cabling, kurundi ruhande, ikoreshwa cyane mubucuruzi, ibigo byamakuru, hamwe na LAN bitewe nigihe gito kigera. Icyangombwa nuguhitamo ubwoko bwa fibre ihuye neza nibisabwa nurusobe mugihe urebye igiciro cya fibre yose. Nkumushinga wurusobe, gufata iki cyemezo ningirakamaro mugushiraho imiyoboro ikora neza kandi yizewe.
