1.1 Imikorere yibanze
Uwitekafibre optiquetransceiver ikubiyemo module eshatu zingenzi zikora: ifoto yamashanyarazi itanga imashini ihindura chip, ibimenyetso byerekana ibimenyetso bya optique (optique ya transceiver ihuriweho na module) hamwe namashanyarazi yerekana amashanyarazi (RJ45). Niba ifite ibikoresho byo gucunga imiyoboro, ikubiyemo kandi imiyoboro yo gucunga amakuru yo gutunganya amakuru.
fibre optique transceiver ni Ethernet yohereza itangazamakuru ryoguhinduranya ihanahana intera ngufi-ihindagurika-ibyuma byamashanyarazi nibimenyetso bya optique. Yitwa kandi guhinduranya amashanyarazi (Fibre Converter) ahantu henshi. Igicuruzwa gikoreshwa mubisanzwe urusobe rwibidukikije aho umugozi wa Ethernet udashobora gupfukirana nafibre optiqueigomba gukoreshwa mu kwagura intera ikwirakwizwa, kandi mubisanzwe ishyirwa muburyo bwo kugera kumurongo wa Broadband metropolitan rezo y'urusobe; icyarimwe, bifasha guhuza ibirometero byanyuma byafibre optiqueumurongo ujya mu mujyi wa interineti na neti yo hanze nayo yagize uruhare runini.
Mu mishinga minini minini, fibre optique ikoreshwa nkuburyo bwo kohereza kugirango hashyizweho umuyoboro wumugongo mugihe cyo kubaka urusobe, mugihe uburyo bwo kohereza LAN imbere muri rusange ari insinga z'umuringa. Nigute ushobora kumenya isano iri hagati ya LAN nafibre optiqueumuyoboro wumugongo? Ibi bisaba guhinduka hagati yibyambu bitandukanye, imirongo itandukanye, hamwe na fibre optique kandi byemeza ubuziranenge bwihuza. Kugaragara kwa optique ya fibre optique ihindura ibimenyetso byamashanyarazi na optique yibyerekezo byombi bigahuzagurika, bigatuma ihererekanyabubasha ryimibare yamakuru hagati yimiyoboro yombi, kandi mugihe kimwe, ryagura intera yohereza imiyoboro kuva kuri metero 100 y'insinga z'umuringa kugera kuri kilometero zirenga 100 (Fibre imwe-fibre).
1.2 Ibintu byingenzi biranga fibre optique
1. Byuzuye neza kuri protocole y'urusobe.
2. Tanga ultra-low latence data yohereza.
3. Shigikira ultra-rugari yubushyuhe bwo gukora.
4. Koresha chip yihariye ya ASIC kugirango umenye amakuru umurongo-wihuta wohereza. Programmable ASIC yibanda kumikorere myinshi kuri chip imwe, kandi ifite ibyiza byo gushushanya byoroshye, kwizerwa cyane, no gukoresha ingufu nke, zishobora gutuma ibikoresho bibona imikorere ihanitse kandi igiciro gito.
5. Ibikoresho byo gucunga imiyoboro irashobora gutanga imiyoboro yo gusuzuma, kuzamura, raporo y'imiterere, raporo y'ibihe bidasanzwe n'imikorere yo kugenzura, kandi irashobora gutanga ibikorwa byuzuye hamwe na logi yo gutabaza.
6. Ibikoresho byo mu bwoko bwa Rack birashobora gutanga imikorere ishyushye kugirango ibungabunge byoroshye no kuzamura bidasubirwaho.
7. Shigikira intera yuzuye (0 ～ 120km).
8. Ibikoresho byinshi bifata igishushanyo mbonera cy’amashanyarazi 1 + 1, gishyigikira ingufu za ultra-rugari zitanga amashanyarazi, kandi zikamenya kurinda amashanyarazi no guhinduranya byikora.
1.3Itondekanya rya fibre optique
Hariho ubwoko bwinshi bwa fibre optique, kandi ubwoko bwabo burahinduka ukurikije uburyo butandukanye.
Ukurikije imiterere ya fibre, irashobora kugabanywamo uburyo bwinshi bwa fibre transceiver hamwe na fibre transibre imwe. Bitewe na fibre optique ikoreshwa, intera yoherejwe ya transceiver iratandukanye. Intera rusange yohereza imiyoboro myinshi yuburyo buri hagati ya kilometero 2 na kilometero 5, mugihe ubwikorezi bwimikorere imwe ishobora kuva kuri kilometero 20 kugeza kuri kilometero 120;
Ukurikije fibre optique isabwa, irashobora kugabanywamo fibre optique ya fibre optique: amakuru yoherejwe kandi yakiriwe yoherezwa kuri fibre imwe optique; dual-fibre optique fibre transceiver: amakuru yakiriwe kandi yoherejwe yoherejwe kuri fibre optique.
Ukurikije urwego rwakazi / igipimo, irashobora kugabanywa muri 10M imwe, 100M fibre optique, 10 / 100M adaptive fibre optique hamwe na 1000M fibre optique. Ukurikije imiterere, irashobora kugabanywa muri desktop (kwihagararaho wenyine) fibre optique ya transiteri hamwe na rack-mount fibre optique. Ibiro bya optique fibre transceiver ikwiranye numukoresha umwe, nko guhura na uplink ya switch imwe muri koridor. Rack-mount (modular) fibre optique transceiver irakwiriye kwegeranya abakoresha benshi. Kurugero, icyumba cya mudasobwa nkuru yumuryango kigomba guhura na uplink ya switch yose mubaturage.
zcc ukurikije imiyoborere y'urusobe, irashobora kugabanywa muburyo bwo gucunga imiyoboro ya optique fibre transceiver hamwe nubwoko butari imiyoboro ya optique fibre transceiver.
Ukurikije ubwoko bwubuyobozi, burashobora kugabanywa mubuyobozi butari umuyoboro wa Ethernet fibre optique ya transiteri: gucomeka no gukina, shiraho uburyo bwakazi bwicyambu cyamashanyarazi ukoresheje ibyuma byifashishwa. Ubwoko bwo gucunga imiyoboro ya Ethernet fibre optique transceiver: shyigikira imiyoboro yabatwara
Ukurikije ubwoko bw'amashanyarazi, burashobora kugabanywamo amashanyarazi yubatswe ya fibre optique: iyubakwa ry'amashanyarazi ni ibikoresho byo mu rwego rwo gutwara; amashanyarazi yo hanze ya fibre optique: ibikoresho byo guhindura amashanyarazi bikoreshwa cyane mubikoresho bya gisivili. Ibyiza byambere nuko ishobora gushyigikira amashanyarazi yagutse cyane, ikamenya neza imbaraga za voltage, kuyungurura no gukingira ibikoresho, no kugabanya ingingo zananiranye zatewe no guhuza imashini; ibyiza bya nyuma nuko ibikoresho ari bito mubunini kandi bihendutse.
Igabanijwe nuburyo bwakazi, uburyo bwuzuye bwa duplex (duplex yuzuye) bivuze ko mugihe kohereza no kwakira amakuru bigabanijwe kumirongo ibiri itandukanye, impande zombi mumatumanaho zishobora kohereza no kwakira icyarimwe. Ubu bwoko bwo kohereza Ubwoko bwuzuye-duplex, kandi uburyo bwuzuye-duplex ntibukeneye guhindura icyerekezo, kubwibyo rero nta gutinda kwigihe guterwa nigikorwa cyo guhinduranya;
Igice cya duplex bivuga ikoreshwa ryumurongo umwe wohereza no kwakira no kohereza. Nubwo amakuru ashobora koherezwa mubyerekezo bibiri, impande zombi mu itumanaho ntizishobora kohereza no kwakira amakuru icyarimwe. Ubu buryo bwo kohereza ni kimwe cya kabiri.
Iyo igice cya duplex cyakiriwe, transmitter hamwe niyakira kuri buri mpera ya sisitemu yitumanaho yimurirwa kumurongo witumanaho binyuze mukwakira / kohereza kugirango uhindure icyerekezo. Kubwibyo, gutinda kwigihe bizabaho.
