1. Chii chinonzi XGS-PON?
ZvoseXG-PONuye XGS-PON ndeyeGPONseries.Kubva pane tekinoroji nzira, XGS-PON ndiyo tekinoroji shanduko yeXG-PON.
Zvose XG-PON uye XGS-PON ndeye 10G PON, musiyano mukuru ndewe: XG-PON is asymmetric PON, iyo uplink / downlink rate yePON port ndeye 2.5G / 10G;XGS-PON iri symmetric PON, iyo uplink/downlink rate yePON port Muyero i10G/10G.
Iwo makuru ePON matekinoroji ari kushandiswa parizvino GPON neXG-PON, ose ari asymmetric PON.Sezvo data remushandisi rekumusoro/downlink richiwanzoita asymmetrical, kutora rimwe guta rekutanga semuenzaniso, avhareji yekukwira kumusoro kweOLT ingori 22% yetraffic yakadzika.Naizvozvo, iwo tekinoroji maitiro easymmetric PON ane hukama nezvinodiwa nevashandisi.match.Zvinotonyanya kukosha, iyo uplink rate yeasymmetric PON yakaderera, mutengo wekutumira zvinhu zvakaita se lasers muONU wakaderera, uye mutengo wemidziyo wakaderera.
Zvisinei, zvido zvevashandisi zvakasiyana.Nekusimuka kwekutepfenyura kwepamoyo uye vhidhiyo yekutarisa masevhisi, kune akawanda uye akawanda mamiriro apo vashandisi vanobhadhara zvakanyanya kune uplink bandwidth.Inbound mitsetse yakatsaurwa inoda kupa symmetrical uplink/downlink maseketi.Aya mabhizinesi anosimudzira kudiwa kweXGS-PON.
2. Kugarisana kweXGS-PON, XG-PON uye GPON
XGS-PON ndiyo shanduko yetekinoroji yeGPON neXG-PON, uye inotsigira kuwana kwakasanganiswa kwemhando nhatu dzeONU: GPON, XG-PON uye XGS-PON.
2.1 Kugarisana kweXGS-PON uye XG-PON
Kunge XG-PON, iyo downlink yeXGS-PON inotora nzira yekutepfenyura, uye iyo uplink inotora nzira yeTDMA.
Sezvo iyo yakadzika yavelength uye yakadzika chiyero cheXGS-PON neXG-PON zvakafanana, iyo yakadzika yeXGS-PON haisiyanise pakati peXGS-PON ONU neXG-PON ONU, uye iyo inoparadzanisa inoparadzira inotepfenyura chiratidzo chepasi kune iyo zvakafanana ODN link Kune yega yega XG (S) -PON (XG-PON uye XGS-PON) ONU, ONU yega yega inosarudza kugamuchira chiratidzo chayo uye inorasa mamwe masaini.
Iyo uplink yeXGS-PON inoita kutumira data zvinoenderana nenguva inotsvedza, uye ONU inotumira data munguva inotsvetwa inobvumidzwa neOLT.Iyo OLT inogovera zvine simba nguva yekumisikidza zvinoenderana nezvinodiwa zvetraffic zveONU dzakasiyana uye rudzi rweONU (ndiyo XG-PON here kana XGS-PON?).Munguva yakagoverwa kuXG-PON ONU, chiyero chekutumira data ndeye 2.5Gbps;munguva yakagoverwa kuXGS-PON ONU, chiyero chekufambisa data i10Gbps.
Zvinogona kuoneka kuti XGS-PON inotsigira musanganiswa kuwana nemhando mbiri dzeONU, XG-PON uye XGS-PON.
2.2 Kugarisana kweXGS-PON uyeGPON
Sezvo uplink/downlink wavelength yakasiyana neyeGPON, XGS-PON inoshandisa Combo solution kugovera ODN neGPON.Nokuda kweiyo nheyo yeCombo solution, tarisa kune chinyorwa "Kukurukurirana pamusoro peChigadziro cheKuvandudza XG-PON Resource Utilization yeCombo Subscriber Board".
Iyo Combo optical module yeXGS-PON inobatanidza GPON optical module, XGS-PON optical module uye WDM multiplexer.
Muchikamu chepamusoro, mushure mokunge chiratidzo chemaziso chinopinda muchiteshi che XGS-PON Combo, WDM inosvina chiratidzo cheGPON uye XGS-PON chiratidzo maererano newavelength, uye zvino inotumira chiratidzo kune zvakasiyana-siyana.
Munzira yekudzika pasi, zviratidzo kubva kuGPON channel uye XGS-PON chiteshi zvinowedzerwa kuburikidza neWDM, uye chiratidzo chakasanganiswa chinoderedzwa kusvika kuONU kuburikidza neODN.Sezvo mawavelengths akasiyana, mhando dzakasiyana dzeONU dzinosarudza mafungu anodiwa kuti agamuchire masaini kuburikidza nemafirita emukati.
Sezvo XGS-PON inotsigira kugarisana neXG-PON, iyo Combo mhinduro yeXGS-PON inotsigira kuwana kwakasanganiswa kweGPON, XG-PON uye XGS-PON matatu marudzi eONU.Iyo Combo optical module yeXGS-PON inonziwo matatu Mode Combo optical module (XG-PON's Combo optical module inonzi maviri-mode Combo optical module nekuti inotsigira kuwana kwakasanganiswa kweGPON uye XG-PON mhando mbiri dzeONU).
3. Mamiriro emusika
Yakakanganiswa nemutengo wemidziyo uye kukura kwemidziyo, mutengo wezvino weXGS-PON wakakwira zvakanyanya kupfuura weXG-PON.Pakati pavo, mutengo wechikwata cheOLT (kusanganisira Combo user board) inenge 20% yakakwirira, uye mutengo weyuniti yeONU inopfuura 50% yakakwirira.
Kunyangwe mitsara yakatsaurirwa mukati ichida kupa uplink/downlink symmetrical circuits, traffic chaiyo yeakawanda inbound yakatsaurirwa mitsetse ichiri kutungamirwa neanotevera maitiro.Kunyange zvazvo kune mamwe mamiriro ezvinhu apo vashandisi vanobhadhara zvakanyanya kune uplink bandwidth, pane inenge isina nyaya yemasevhisi asingakwanisi kuwanikwa kuburikidza neXG-PON asi inofanira kuwanikwa kuburikidza neXGS-PON.
