Igipimo cya ieee802.3av gisobanura 10g / 1g (igipimo cyo kuzamuka 10g / kumanura igipimo cya 1g) uburyo bwa asimmetrike yuburyo bwimiterere (aha ni ukuvuga 10g / 1g uburyo butemewe) na 10g / 10g (igipimo cyo kuzamuka no kugabanuka byombi ni 10g) bihuje bibiri A urwego rwumubiri (aha ruvugwa nka 10g / 10g uburyo bwo guhuza):
Olt muburyo bwa 10g / 1g idahuje igitsina irashobora guhuzwa na onu muburyo bwa 1g / 1g hamwe na onu muburyo bwa 10g / 1g.OLT muburyo bwa 10g / 10g burashobora guhuza na onu muburyo bwa 1g / 1g, onu muburyo bwa 10g / 1g, na onu muburyo bwa 10g / 10g.
OLT muburyo bwa simmetrike na OLT muburyo bwa asimmetrike ni kimwe muburyo bwo kumanura inzira ya optique yinzira yumubiri, naho umuyoboro wa 10g ukoresha uburebure bwa 1577nm na 64b / 66b kodegisi;ntakibazo rero niba onu iri muburyo bwa simmetrike cyangwa muburyo bwa asimmetric, irashobora kwakira amakuru yamanutse kuva olt.Olt izajya itangaza buri gihe mpcpdsicoverygate (ingingo nyinshi zo kugenzura protocole, kugenzura ingingo nyinshi).Umwanya wo kuvumbura amakuru mumurongo ukoreshwa muburyo bwihariye kugirango umenyeshe ubushobozi bwa idirishya ryubushobozi (1g, 10g, 1g + 10g igipimo cyibiri), kandi onu irashobora kubona olt ikoresheje ubu buryo bwo gukora.
Onu muburyo bwa simmetrike nuburyo bwa asimmetricike burahuye rwose kuri mac layer (kugenzura itangazamakuru, kugenzura uburyo bwo kugenzura uburyo bwo hagati), kandi itandukaniro riri hagati yaryo ryibanze murwego rwa phy (layer physique, epfo ya osi), na kohereza ibipimo bya phy layer biterwa na Shyiramo optique module ya onu:
Iyo module idasanzwe ya optique yinjijwe muri onu (ni ukuvuga, onu ni onimmetric onu), kubera ko igipimo cyo kuzamuka cya module idasanzwe ya optique igera kuri 1g, phy layer ya onu irashobora gusa gushiraho igipimo cyo kohereza 1g gukora muburyo butemewe.Iyo moderi ya optique ya module yinjijwe muri onu, kuva igipimo cyo kuzamuka cya module ya optique igera kuri 10g, onu irashobora gushiraho igipimo cyo kohereza igipimo cya phy kuri 10g kugirango ikore muburyo bwa simmetrike, cyangwa igena igipimo cyo kohereza cya phy layer kugeza 1g kugirango ikore muburyo butemewe.
Ariko, onu na olt bihari bizagira inenge zikurikira mugihe urusobe ruzamuwe:
Mugihe cyo kuzamura urusobe, OLT irashobora guhinduka hagati yuburyo bwa simmetrike nuburyo butemewe, ariko ONU ntishobora guhinduka ukurikije ihinduka rya OLT.Kurugero, OLT ihinduranya muburyo bwa simmetrike ijya muburyo butemewe, ariko ONU iracyari muburyo bwo guhuza.Muri iki gihe, iherezo ryibanze (olt) nuburyo bwa kure (onu) uburyo ntibuhuye.Ibikoresho byo gutekinika:
Intego ku nenge ziriho mubuhanzi bwabanjirije iki, ikibazo cya tekiniki cyakemuwe nubuvumbuzi bwa none ni: uburyo bwo gukora onu guhuza n'imiterere ukurikije uburyo bwo guhindura olt mugihe olt ikora ihinduka ryuburyo bwa simmetrike / uburyo butemewe;ibyivumbuwe byubu byerekana neza guhuza olt hamwe na onu Guhuza n'imihindagurikire y'ikirere, ntihazabaho kudahuza hagati yimiterere yanyuma nuburyo bwa kure.
Kugirango ugere ku ntego yavuzwe haruguru, onu yatanzwe nubuvumbuzi bwa none ihuza na 10g / 10g hamwe na 10g / 1g asimmetrie, harimo intambwe zikurikira:
Intambwe a: Shaka ubwoko bwa optique module ya onu.Iyo optique module ari module ihuriweho, menya uburyo bukora bwa onu.Niba uburyo bwo gukora bwa onu ari uburyo bwo guhuza, jya kuri intambwe b;niba uburyo bwakazi bwa onu butemewe, jya kuri intambwe c;
Intambwe b: Menya niba umubare wamadirishya yamakuru yatanzwe na olt muburyo bwa asimmetrike ari hejuru yurugero rwateganijwe, niba aribyo, hindura uburyo bwakazi bwa onu kuva muburyo bwa simmetrike ujya muburyo butemewe, hanyuma urangire;bitabaye ibyo, komeza uburyo bwakazi bwa onu, hanyuma urangire;
Intambwe c: Menya niba umubare wamadirishya yamakuru yatanzwe na olt muburyo bwa simmetrike ari hejuru yurugero rwateganijwe, niba aribyo, hindura uburyo bwakazi bwa onu kuva muburyo butamenyerewe muburyo bwa simmetrike, hanyuma birangire;bitabaye ibyo, komeza uburyo bwakazi bwa onu, iherezo.
Ukurikije igisubizo cya tekiniki yavuzwe haruguru, inzira yo kubona ubwoko bwa optique module ya onu yasobanuwe mu ntambwe a ni: iyo onu itangiye, shaka ubwoko bwa optique module ya onu:
Niba optique module ari module idasanzwe, ihagarika inzira kandi irangire;
Niba optique module ari optique ya module ihuriweho, mugihe onu ihindutse kuva kumuri-itara kugeza kuri leta ibishinzwe, ongera ushake ubwoko bwa optique ya module ya onu, niba optique module ari module ihuriweho, komeza inzira ikurikira y'intambwe a;niba optique module idahwitse module, guhagarika inzira no kurangiza.
Onu itangwa nubuvumbuzi bwa none ihuza na sisitemu ya 10g / 10g hamwe na 10g / 1g sisitemu idasanzwe, harimo module yo gutahura onu, uburyo bwo guhinduranya uburyo bwa simmetrike, hamwe nuburyo bwo guhinduranya uburyo butemewe kuri onu;
Module ya onu ikoreshwa kuri: kubona ubwoko bwa optique module ya onu, mugihe module ya optique ari module ihuza optique, menyesha uburyo bukoreshwa bwa onu, niba uburyo bwakazi bwa onu aribwo buryo bwo guhuza, ohereza uburyo bwo guhuza ibimenyetso byerekana uburyo bwo guhinduranya uburyo;Niba uburyo bwakazi bwa onu nuburyo butamenyerewe, uburyo bwo guhinduranya uburyo bwoherejwe bwoherejwe muburyo butemewe bwo guhindura module;
Uburyo bwa simmetrike yo guhinduranya module ikoreshwa kuri: nyuma yo kwakira ibimenyetso byerekana uburyo bwo guhinduranya ibimenyetso, suzuma niba umubare wamakuru yidirishya yatanzwe na olt muburyo bwa asimmetrike agera kumurongo wateganijwe cyangwa utaribyo, kandi niba aribyo, hindura uburyo bwakazi bwa onu kuva muburyo bwa simmetrike kugeza muburyo butemewe;Ubundi komeza uburyo bwakazi bwa onu;
Uburyo bwa asimmetrike bwo guhindura module bukoreshwa kuri: nyuma yo kwakira ibimenyetso byerekana uburyo bwo guhinduranya ibimenyetso, suzuma niba umubare wamadirishya yamakuru yoherejwe na olt muburyo bwa simmetrike ari hejuru yurugero rwateganijwe, kandi niba aribyo, hindura uburyo bwakazi bwa onu kuva uburyo butamenyerewe kuburyo bwa simmetric;Bitabaye ibyo komeza onu uburyo bwo gukora.
Hashingiwe kuri gahunda ya tekinike yavuzwe haruguru, inzira yo kubona ubwoko bwa optique module ya onu muri module ya onu detection ni: iyo onu itangiye, shaka ubwoko bwa optique ya module ya onu:
Niba optique module ari module idasanzwe, reka guhagarika akazi;
Niba optique module ari module ihuza optique, mugihe onu ihindutse kuva kumuri-itara kugeza kuri leta ifitanye isano, ongera ushake ubwoko bwa optique module ya onu, niba module ya optique ari module ya optique, komeza inzira ikurikira ya module yo kumenya;niba optique module ari modulike idasanzwe, guhagarika akazi.
Ugereranije nubuhanzi bwambere, ibivumbuwe byubu bifite ibyiza bya:
.kuriyi shingiro, yerekeza ku ntambwe b na intambwe c yubuvumbuzi bwa none, birashobora kugaragara ko igihangano cyubu gishobora kumenya uburyo bwo gukora bwa olt, kandi ukurikije uburyo bwa olt, kugirango uhuze kugirango uhindure imikorere yakazi. ya onu, kugirango tumenye neza guhuza n'imihindagurikire hagati ya olt na onu, kandi ntihazabaho kudahuza hagati yuburyo bwanyuma bwaho nuburyo bwanyuma bwubuhanzi bwambere.
