Amashanyarazi ya fibre optique ni umuyoboro wa Ethernet wohereza itangazamakuru rihinduranya intera ngufi igoretse-ibyuma byamashanyarazi nibimenyetso bya optique.Yitwa kandi fibre ihindura ahantu henshi.Ibicuruzwa muri rusange bikoreshwa mubidukikije byukuri aho insinga za Ethernet zidashobora gutwikirwa kandi fibre optique igomba gukoreshwa kugirango yongere intera yoherejwe, kandi mubisanzwe ishyirwa mubikorwa byogukoresha umurongo mugari wa metropolitani.
Uruhare rwa fibre optique
Fibre optique ya transibiveri ikoreshwa mubisanzwe mubikorwa byurusobe aho insinga za Ethernet zidashobora gutwikirwa kandi fibre optique igomba gukoreshwa kugirango yongere intera yoherejwe.Muri icyo gihe, bagize kandi uruhare runini mu gufasha guhuza ibirometero byanyuma byumurongo wa fibre optique hamwe numuyoboro wa metropolitani hamwe numuyoboro wo hanze.Uruhare rwa.Imikorere ya fibre optique transceiver nuguhindura ibimenyetso byamashanyarazi dushaka kohereza mubimenyetso bya optique no kubyohereza hanze.Mugihe kimwe, irashobora guhindura ibimenyetso byakiriwe neza mubimenyetso byamashanyarazi hanyuma ikabishyira kumpera yo kwakira.
Ibyiciro byafibre optique
1.Uburyo bumwe bwa fibre optique transceiver: intera yoherejwe kuva kuri kilometero 20 kugeza kuri kilometero 120.
2.Multimode fibre optique transceiver: intera yohereza ibirometero 2 kugeza kuri kilometero 5.
Kurugero, imbaraga zo kohereza za 5km fibre optique transceiver muri rusange iri hagati ya -20 na -14db, naho ibyakirwa ni -30db, ukoresheje uburebure bwa 1310nm;mugihe imbaraga zo kohereza za 120km fibre optique transceiver iba hagati ya -5 na 0dB, hamwe no kwakira sensibilité Kuri -38dB, koresha uburebure bwa 1550nm.
Ibiranga fibre optique
Ububiko bwa fibre optique busanzwe bufite ibintu byingenzi bikurikira:
1. Tanga ultra-low latence data yohereza.
2. Byuzuye neza kuri protocole y'urusobe.
3. Koresha chip ya ASIC yihariye 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.
4. Ibikoresho byo mu bwoko bwa Rack birashobora gutanga imikorere ishyushye kugirango ibungabungwe byoroshye no kuzamura bidasubirwaho.
5. Ibikoresho byo gucunga imiyoboro irashobora gutanga imirimo nko gusuzuma imiyoboro, kuzamura, raporo y'imiterere, raporo y'ibihe bidasanzwe no kugenzura, kandi irashobora gutanga ibikorwa byuzuye hamwe na logi yo gutabaza.
6. Ibikoresho byinshi bifata igishushanyo mbonera cyamashanyarazi 1 + 1, gishyigikira ingufu zidasanzwe zitanga amashanyarazi, kandi zikamenya kurinda amashanyarazi no guhinduranya byikora.
7. Shigikira ultra-rugari yubushyuhe bwo gukora.
8. Shigikira intera yuzuye yoherejwe (kilometero 0 ~ 120).
Ibyiza bya fibre optique
Ku bijyanye na fibre optique, abantu akenshi ntibagereranywa bagereranya fibre optique hamwe na switch hamwe nibyambu bya optique.Ibikurikira bivuga cyane cyane ibyiza bya fibre optique ihinduranya ibyambu bya optique.
Mbere ya byose, igiciro cya fibre optique ihinduranya wongeyeho ibintu bisanzwe bihendutse cyane kuruta optique ya optique, cyane cyane optique imwe ya optique izabura icyambu kimwe cyangwa byinshi byamashanyarazi nyuma yo kongeramo modul optique, ishobora gutuma abashoramari murwego runini Kugabanya ishoramari ryimbere.
Icyakabiri, kubera ko ibyinshi mubikoresho bya optique byahinduwe bidafite ibipimo bihuriweho, iyo moderi ya optique imaze kwangirika, bigomba gusimbuzwa modules imwe kuva uwabikoze mbere, bizana ibibazo bikomeye kubitaho nyuma.Nyamara, ntakibazo kijyanye no guhuza no gutumanaho hagati yibikoresho byabakora uruganda rutandukanye rwa fibre optique, bityo rero iyo byangiritse, birashobora gusimburwa nibindi bicuruzwa byakozwe, byoroshye kubungabunga.
Mubyongeyeho, fibre optique transcevers ifite ibicuruzwa byuzuye kuruta ibyambu bya optique muburyo bwo kohereza.Nibyo, optique ya optique nayo ifite ibyiza mubice byinshi, nkubuyobozi bumwe hamwe nogutanga amashanyarazi hamwe.
