1. Itandukaniro riri hagati yuburyo bumwe nuburyo bwinshi bwa fibre optique
Diameter yibanze ya fibre ya multimode ni 50 ~ 62.5 mm, diameter yo hanze yambarwa ni 125 mm, naho diameter yibanze ya fibre imwe imwe ni 8.3 mm, naho diameter yo hanze yambarwa ni 125μm.Uburebure bwumurongo wa fibre optique ni 0,85 mm kuri metero ngufi, 1,31 mm na 1.55 mm kuri metero ndende.Gutakaza fibre muri rusange bigabanuka hamwe nuburebure bwumuraba, igihombo cya 0,85 mm ni 2.5dB / km, igihombo cya 1.31 mm ni 0.35dB / km, naho 1.55μm ni 0,20dB / km, nicyo gihombo gito cya fibre, uburebure bwa 1.65 Igihombo kiri hejuru ya μm gikunda kwiyongera.Bitewe n'ingaruka zo kwinjiza OHˉ, hari impinga zo gutakaza ziri hagati ya 0.90 ~ 1.30 mm na 1.34 ~ 1.52 mm, kandi iyi ntera yombi ntabwo ikoreshwa neza.Kuva mu myaka ya za 1980, fibre imwe yuburyo bumwe yakunze gukoreshwa, kandi uburebure bwumurambararo wa 1,31 mm bwakoreshejwe mbere.
Fibre fibre
Fibre ya Multimode: Hagati yikirahure hagati ni ndende (50 cyangwa 62.5 mm), ishobora kohereza urumuri muburyo bwinshi.Ariko ikwirakwizwa rya intermodal nini nini, igabanya inshuro zo kohereza ibimenyetso bya digitale, kandi bizaba bikomeye hamwe no kwiyongera kwintera.Kurugero: 600MB / KM fibre ifite umurongo wa 300MB gusa kuri 2KM.Kubwibyo, intera ya fibre fibre yoherejwe ni ngufi, mubisanzwe kilometero nkeya.
uburyo bumwe bwa fibre
Fibre imwe-imwe (Fibre Mode imwe): Intangiriro yikirahure hagati ni ntoya cyane (diameter yibanze ni 9 cyangwa 10 mm), kandi uburyo bumwe bwumucyo bushobora kwanduzwa.Kubwibyo, itandukanyirizo ryayo intermodal ni nto cyane, ikwiranye nogutumanaho kure, ariko hariho no gutatanya ibintu hamwe no gukwirakwiza umurongo wa waveguide, bityo fibre imwe-imwe ifite ibisabwa byinshi mubugari bwikigereranyo no guhagarara kwumucyo, ni ukuvuga , ubugari bwikigereranyo bugomba kuba bugufi kandi buhamye.Ba mwiza.Nyuma, byagaragaye ko ku burebure bwa 1.31 mm, gutatanya ibintu hamwe no gukwirakwiza umurongo wa fibre imwe ya fibre imwe ni nziza kandi mbi, kandi ubunini ni bumwe.Ibi bivuze ko ku burebure bwa 1,31 mm, ikwirakwizwa rusange rya fibre imwe-imwe ni zeru.Uhereye kubihombo biranga fibre, 1.31μm ni idirishya rike-rya idirishya rya fibre.Muri ubu buryo, akarere ka 1.31μm gafite uburebure bwahindutse idirishya ryiza ryo gukora itumanaho rya fibre optique, kandi ni naryo tsinda rikuru rya sisitemu yo gutumanaho ya fibre optique.Ibipimo nyamukuru bya fibre isanzwe ya 1.31μm igenwa nubumwe mpuzamahanga bwitumanaho ITU-T mubyifuzo bya G652, iyi fibre nayo yitwa fibre G652.
Ese tekinoroji yuburyo bumwe nuburyo bwinshi ikorerwa icyarimwe?Nibyo koko ibyo byateye imbere kandi byinshi-byateye imbere cyane?Mubisanzwe, uburyo-bwinshi bukoreshwa mu ntera ngufi, kandi uburyo bumwe gusa bukoreshwa mu ntera ya kure, kubera ko ihererekanyabubasha no kwakira fibre-moderi nyinshi Igikoresho gihendutse cyane kuruta uburyo bumwe.
Fibre imwe-imwe ikoreshwa mugukwirakwiza intera ndende, na fibre-moderi nyinshi ikoreshwa mugukwirakwiza amakuru murugo.Gusa uburyo bumwe bushobora gukoreshwa intera ndende, ariko uburyo bwinshi ntabwo bukoreshwa muburyo bwo kohereza amakuru murugo.
Niba fibre optique ikoreshwa muri seriveri nibikoresho byo kubika nuburyo bumwe cyangwa uburyo bwinshi Benshi muribo bakoresha uburyo bwinshi, kuko ndimo gukora gusa fibre optique kandi ntabwo bisobanutse neza kuri iki kibazo.
Ese fibre optique igomba gukoreshwa kubiri, kandi hari ibikoresho nkibikoresho bimwe nkibikoresho bya fibre bihinduranya?
Ese fibre optique igomba gukoreshwa kubiri?Nibyo, mugice cya kabiri cyikibazo, urashaka kohereza no kwakira urumuri kuri fibre optique?Ibi birashoboka.Ubushinwa Telecom ya 1600G umugongo optique fibre fibre nkiyi.
Itandukaniro ryibanze cyane hagati yuburyo bumwe bwa fibre optique hamwe nuburyo bwinshi bwa fibre optique ni intera yoherejwe.Uburyo bwinshi bwa optique fibre transceiver ni imiyoboro myinshi kandi yerekana ibyapa byinshi muburyo bwo gukora, kubwibyo rero intera yerekana ibimenyetso ni ngufi, ariko biroroshye, kandi ntabwo ari ngombwa gukoresha ubwubatsi bwa intranet yaho .Fibre imwe ni ihererekanyabubasha rimwe, bityo rero irakwiriye kohererezanya imirongo miremire kandi igizwe no kubaka umuyoboro wambukiranya umujyi.
2. Nigute ushobora gutandukanya uburyo bumwe nuburyo bwinshi bwa fibre optique
Rimwe na rimwe, dukeneye kwemeza ubwoko bwa fibre optique transceiver, none nigute dushobora kumenya niba fibre optique transceiver ari uburyo bumwe cyangwa uburyo bwinshi?
1. Tandukanya n'umutwe wumuhondo, fungura fibre optique transceiver yumutwe wumukungugu wumutwe, hanyuma urebe ibara ryibice bigize interineti mumutwe wumutwe.Uruhande rwimbere rwimikorere imwe ya TX na RX rwometseho ceramique yera, naho intera yuburyo bwinshi ni umukara.
2. Tandukanya icyitegererezo: muri rusange reba niba hari S na M mubyitegererezo, S bisobanura uburyo bumwe, M bisobanura uburyo bwinshi.
3. Niba yarashizweho kandi ikoreshwa, urashobora kubona ibara rya fibre jumper, orange nuburyo bwinshi, umuhondo nuburyo bumwe
