Tsananguro yemifananidzo
Mufananidzo 1 iratidziro yenzira yekuti onu ienderane nekuenzana kwe10g/10g uye kusaenzana kwe10g/1g muchimiro chechinhu chitsva ichi.
Nzira dzakadzama
Chigadzirwa ichi chichatsanangurwa zvakadzama pazasi pamwe chete nemifananidzo nemaitiro azvo.
Iyo onu iri muchimiro chechinhu ichi chitsva inochinjika ku 10g/10g symmetry uye 10g/1g asymmetry, uye inoshandiswa muchimiro che 10gepon.
Pahwaro uhwu, sezvakaratidzwa paMufananidzo 1, onu iri muchimiro chechinhu ichi chitsva inochinjika ku 10g/10g symmetry uye 10g/1g asymmetry, kusanganisira matanho anotevera:
s1: Kana onu yatanga, tora mhando ye optical module ye onu. Kana optical module iri symmetrical optical module, zvinoreva kuti current onu ine kugona kushanda mune symmetrical mode uye asymmetrical mode. Panguva ino, enda ku s2. Kana optical module iri . Asymmetric optical module zvinoreva kuti current onu ine kugona kushanda mu asymmetric mode chete. Panguva ino, onu inogona kungochinjika kune 10g/10g symmetric mode, saka inoguma zvakananga kuderedza mari yekushanda uye kuvandudza kushanda zvakanaka.
s2: Kana onu ikachinja kubva pakusava nechiedza kuenda pakuva nechiedza, torazve rudzi rwe optical module ye onu. Kana optical module iri symmetrical optical module, enda ku s3 (chikonzero chakafanana ne s1). Kana optical module iri asymmetrical optical module, wobva waipedzisa zvakananga (chikonzero chakafanana ne s1).
Nheyo ye s2 ndeiyi: chikonzero nei onu ichichinja kubva pamamiriro ekusava nechiedza kuenda pamamiriro ekuva nechiedza ndechekuti: optical module iri mu onu inotsiviwa, saka mhando ye optical module inofanira kuwanikwa zvakare kuti ive nechokwadi chekuti onu inogoneka kuzivikanwa nemazvo. Pamusoro pezvo, nekuti pane nzvimbo apo onu inobatidzwa kana yakabatana ne optical fiber, onu yagara ichigamuchira downlink light inotumirwa ne olt, uye ingasakwanise kuona chiitiko chinoshanduka kubva pamamiriro ekusava nechiedza kuenda kumamiriro ekuva nechiedza. Naizvozvo, kuitira kuti s2 ive nechokwadi chekuti inogona. Zvinotariswa kuti onu inoshanduka kubva pamamiriro ekusava nechiedza kuenda kumamiriro ekuva nechiedza. Zvakakosha kudzima basa rekugamuchira chiedza re optical module panguva yekutanga onu mu s1, uye wobva wabatidza basa rekugamuchira chiedza re optical module mushure mekunge onu yatanga. Gadzira chiitiko icho onu inoshanduka kubva pamamiriro erima kuenda kumamiriro ekuva nechiedza.
Maitiro ekuwana mhando ye onu optical module mu s2 ndeekuti: verenga zvakare rejista ye optical module kuburikidza ne i2c (bhazi re serial rakareruka, rine waya mbiri-mbiri rakagadzirwa nekambani ye philips) kuti uwane ruzivo rwemhando ye optical module (hunhu hwemugadziri uye hunhu hwemuenzaniso). Wana mhando ye optical module inoenderana zvichienderana neruzivo rwemhando. Maitiro chaiwo ndeekuti: gadzirira database ye optical module munharaunda. Optical module database inosanganisira ruzivo rwemhando ye optical module uye rudzi rwakakodzera. Rudzi rwakakodzera runoshandiswa serudzi rwe optical module.
s3: Sarudza maitiro ekushanda aripo iye zvino e onu. Kana maitiro ekushanda e onu ari symmetric mode, zvakakosha kuona kana onu inofanira kushandurwa kuita asymmetric mode zvichienderana ne OLT, kureva kuti, enda ku s4; kana maitiro ekushanda e onu ari asymmetric mode, saka unofanirwa kuona kana onu ichizochinja kuita symmetric mode zvichienderana ne olt, kureva kuenda ku s5.
s4: Sarudza kana nhamba yenguva iyo olt inotumira ruzivo rwewindo muchimiro cheasymmetric iri pamusoro pemuganho wakatarwa (kutonga kwakawanda kunokonzerwa nekufunga kwesimba, ka5 muchimiro ichi), uye kana zvakadaro, zvinoratidza kuti olt ine uplink 1g chete. Kugona, kureva kuti, OLT iri muchimiro cheasymmetric, panguva ino, chinja maitiro ekushanda eONU kubva muchimiro chesymmetric kuenda kuchimiro cheasymmetric, uye kuguma; zvikasadaro, zvinoratidza kuti OLT ine kugona kweuplink 10g chete (ndiko kuti, ONU yaburitsa ruzivo rwewindow rwechimiro chesymmetric), Kureva kuti, olt inotsigira maitiro esymmetric. Panguva ino, maitiro ekushanda eonu anochengetwa, uye kuguma kwapera.
s5: Sarudza kana huwandu hweruzivo rwewindows rwunotumirwa neolt ku symmetric mode hwasvika pamuganho wakatarwa (kashanu mu embodiment iyi). Kana zvakadaro, zvinoratidza kuti olt ine kugona kwekuwedzera 10g, uye inochinja kubva ku asymmetric mode kuenda ku symmetric mode. Panguva ino, chinja working mode ye onu kubva ku asymmetric mode kuenda ku symmetric mode, uye end; zvikasadaro, zvinoratidza kuti OLT ine kugona kwekuwedzera 1G chete, kureva kuti, OLT iri mu asymmetric mode, uye panguva ino, chengetedza working mode ye onu, uye end.
Ruzivo rwewindow rweasymmetric mode mu s4 uye ruzivo rwewindow rwesymmetric mode mu s5 zvinowanikwa mu mpcpgate frame yakapihwa neOLT. Ruzivo rwewindow rweasymmetric mode i uplink 1g window information, uye ruzivo rwewindow rwesymmetric mode i uplink 10g window information.
Tichitaura nezve s1 kusvika s2, zvinogona kuonekwa kuti kuratidzwa kwechigadzirwa ichi kunowana mhando ye onu kutanga, uye tichitarisa s3 kusvika s5, zvinogona kuonekwa kuti kuratidzwa kwechigadzirwa ichi kunogona kuona mashandiro eOLT, uye kugadzirisa mashandiro eONU zvichienderana nemaitiro ekushanda eOLT, kuitira kuti OLT neONU zvigone kugadziriswa zvakakwana, uye kusawirirana pakati pemamiriro ekupedzisira emunharaunda uye maitiro ekupedzisira ekure muhunyanzvi hwekare hakuzoitiki.
Iyo onu iri muchimiro chechinhu chitsva ichi inochinjika kune 10g/10g symmetrical systems uye 10g/1g asymmetrical systems, uye inoratidzwa nekuti: sisitimu iyi inosanganisira onu detection module, symmetrical mode switching module, uye asymmetrical mode switching module yakarongwa pa onu.
Module yekuona onu inoshandiswa ku: kudzima basa rekugamuchira chiedza che optical module panguva yekutanga kwe onu, uye kuwana mhando ye optical module ye onu. Kana optical module iri asymmetric optical module, rega kushanda; kana optical module iri symmetrical optical module, kana onu ikachinja kubva ku non-light state kuenda ku light state, mhando ye optical module ye onu inotorwazve:
Kana optical module iri symmetrical optical module, tsvaga rudzi rwe optical module ye onu. Kana optical module iri symmetrical optical module, sarudza current working mode ye onu. Kana working mode ye onu iri symmetrical mode, tumira symmetrical mode switching ku symmetrical mode switching module Signal; kana working mode ye onu iri asymmetric mode, tumira asymmetric mode switching signal ku asymmetric mode switching module, uye vhura light receiving function ye optical module mushure mekunge onu yatanga;
Kana module ye optical iri module ye optical isina kuenzana, rega kushanda.
Module yekuchinja symmetric mode inoshandiswa: mushure mekugamuchira chiratidzo chekuchinja symmetric mode, kutonga kana huwandu hweruzivo rwewindow rwakapihwa ne olt mu asymmetric mode hunosvika pamuganho wakatarwa kana kwete, uye kana zvakadaro, chinja working mode ye onu kubva mu symmetric mode kuenda ku asymmetric mode; Zvikasadaro chengetedza working mode ye onu;
Module yekuchinja maitiro asymmetric inoshandiswa: mushure mekugamuchira chiratidzo chekuchinja maitiro asymmetric, tonga kana huwandu hweruzivo rwewindo rwunotumirwa ne olt ku symmetric mode huri pamusoro pemuganho wakataurwa, uye kana zvakadaro, chinja maitiro ekushanda e onu kubva ku asymmetric mode kuenda ku symmetric mode ; Zvikasadaro chengetedza onu ichishanda.
Ruzivo rwewindow rweasymmetric mode musymmetric mode switching module uye ruzivo rwewindow rwesymmetric mode muasymmetric mode switching module zvinowanikwa mu mpcpgate frame inotumirwa neOLT; ruzivo rwewindow rweasymmetric mode ndirwo ruzivo rweuplink 1g window, Ruzivo rwewindow rwesymmetric mode muasymmetric mode switching module ndirwo ruzivo rweuplink 10g window.
Zvinofanira kucherechedzwa kuti kana sisitimu yakapihwa nekugadzirwa kwechigadzirwa ichi ichiita kutaurirana pakati pemamodule, kupatsanurwa kwemamodule anoshanda ataurwa pamusoro apa kunoshandiswa semuenzaniso wekuratidza. Mukushandisa kwechokwadi, kugoverwa kwebasa kwataurwa pamusoro apa kunogona kupedzwa nemamodule akasiyana anoshanda zvichienderana nezvinodiwa. Kureva kuti, chimiro chemukati chesisitimu chakakamurwa kuita mamodule akasiyana anoshanda kuti apedzise mabasa ese kana chikamu chemabasa atsanangurwa pamusoro apa.
Uyezve, chigadzirwa ichi hachingogumiri pamhando dzataurwa pamusoro apa. Kune avo vane hunyanzvi hwemazuva ese muunyanzvi, pasina kusiya musimboti wechigadzirwa ichi, zvimwe zvigadziriso zvinogona kuitwawo, uye izvi zvigadziriso zvinoonekwawo sechigadzirwa ichi. mukati mekudzivirira. Zviri mukati zvisina kutsanangurwa zvakadzama mutsanangudzo iyi ndezvehunyanzvi hwekare hunozivikanwa neavo vane hunyanzvi muunyanzvi.
