Fibre optique ni fibre yoroheje, ibonerana ikozwe mubirahuri cyangwa plastiki bisohotse, binini cyane kuruta umusatsi wabantu.Fibre optique ikoreshwa cyane nkuburyo bwo kohereza urumuri hagati yimpande zombi za fibre ugasanga ikoreshwa cyane mumatumanaho ya fibre optique, aho yemerera kwanduza intera ndende no kumurongo mugari kuruta insinga z'insinga.Fibre optique isanzwe irimo intoki ibonerana izengurutswe nibikoresho byambaye neza hamwe nurwego rwo hasi rwo kugabanuka.Umucyo ubikwa muribanze na phenomenon yo kugaragariza imbere imbere itera fibre gukora nkumuhengeri.Muri rusange, hari ubwoko bubiri bwa fibre optique: fibre ishyigikira inzira nyinshi zo gukwirakwiza cyangwa uburyo bwo guhinduranya bwitwa fibre fibre (MMF), mugihe izishyigikira uburyo bumwe zitwa fibre imwe (SMF).Uburyo bumwe vs fibre fibre: ni irihe tandukaniro riri hagati yabo?Gusoma iyi nyandiko bizagufasha kubona igisubizo.
Uburyo bumwe vs Multimode Fibre: Nubuhe buryo bumwe bwa optique fibre?
Mu itumanaho rya fibre-optique, uburyo bumwe bwa optique fibre (SM) ni fibre optique yagenewe gutwara urumuri gusa munsi ya fibre - uburyo bwo guhinduranya.Kuburyo bumwe bwa optique fibre, ntakibazo ikora kuri 100 Mbit / s cyangwa 1 Gbit / s igipimo cyitariki, intera yoherejwe irashobora kugera byibuze kuri 5 km.Mubisanzwe, ikoreshwa mugukwirakwiza ibimenyetso birebire.
Mode imwe vs Multimode Fibre: Fibre optique ni iki?
Multimode optique fibre (MM) ni ubwoko bwa fibre optique ikoreshwa cyane mu itumanaho intera ngufi, nko mu nyubako cyangwa mu kigo.Umuvuduko usanzwe wihuta nintera ntarengwa ni 100 Mbit / s kubirometero bigera kuri 2 km (100BASE-FX), 1 Gbit / s kugeza kuri 1000m, na 10 Gbit / s kugeza kuri m 550.Hariho ubwoko bubiri bwibipimo byinshi: intambwe yintambwe hamwe nindangagaciro.
Ni irihe tandukaniro riri hagati yuburyo bumwe bwa fibre optique na multimode?
Kwitonda: Kwiyongera kwa fibre multimode irarenze fibre ya SM kubera diameter nini nini.Fibre yibanze ya kabili yuburyo bumwe iragufi cyane, urumuri rero runyura muriyi nsinga ya fibre optique ntirugaragarira inshuro nyinshi, bigatuma attenuation igera byibuze.
| Fibre imwe | Multimode Fibre | ||
| Attenuation kuri 1310nm | 0.36dB / km | Attenuation kuri 850nm | 3.0dB / km |
| Attenuation kuri 1550nm | 0.22dB / km | Attenuation kuri 1300nm | 1.0dB / km |
Diameter yibanze:Itandukaniro nyamukuru hagati ya multimode nuburyo bumwe bwa fibre ni uko iyambere ifite diameter nini nini cyane, mubisanzwe ifite diameter yibanze ya 50 cyangwa 62.5 µm na diameter yambarwa ya 125 µm.Mugihe bisanzwe fibre isanzwe ifite diameter yibanze hagati ya 8 na 10 µm na diameter yambarwa ya 125 µm.
Umuyoboro mugari
Kubera ko fibre fibre ifite intoki nini-nini kuruta fibre imwe, ishyigikira uburyo burenze bumwe bwo gukwirakwiza.Uretse ibyo, nka fibre fibre nyinshi, fibre imwe-imwe yerekana uburyo bwo gutandukanya ibintu biva muburyo butandukanye, ariko uburyo bwo gukwirakwiza fibre yuburyo bumwe ntiburi munsi yuburyo bwinshi.Kubera izo mpamvu, fibre yuburyo bumwe irashobora kugira umurongo mwinshi kuruta fibre-moderi nyinshi.
Ibara ry'ikoti
Ibara ry'ikoti rimwe na rimwe rikoreshwa mu gutandukanya insinga za multimode nuburyo bumwe.Ubusanzwe TIA-598C irasaba, kubisabwa bitari ibya gisirikare, gukoresha ikoti ry'umuhondo kuri fibre imwe imwe, na orange cyangwa aqua ya fibre fibre, bitewe n'ubwoko.Abacuruzi bamwe bakoresha violet kugirango batandukanye imikorere yo hejuru ya OM4 itumanaho nubundi bwoko.
