PON tekinoroji yagara iine kugona kuzvivandudza pachayo uye kujairana nezvitsva zvemusika zvinodiwa. Kubva pakumhanya kwerekodhi kusvika kune mbiri chiyero chiyero uye akawanda lambdas, PON yagara iri "gamba" rebroadband, iyo inogonesa kupararira uye kushanda kwemasevhisi matsva. Kusimudzirwa kwebhizinesi kunogoneka.
Sezvo network ye5G inotanga kuvaka, nyaya yePON iri kuzarurawo peji itsva.Nguva ino, chizvarwa chinotevera chePON teknolojia iri kutora paradigm itsva kuti iwane simba repamusoro zvakanyanya. iyo nzira yekufambisa yakashandiswa munhoroondo yePON tekinoroji, inomiririra chikamu chinotevera chefiber evolution, chidimbu chitsva muPON nyaya.
Kubudirira kwemitengo ndiyo kiyi
Pane zvinhu zviviri zvinodiwa kuti uwane tekinoroji kubudirira: mutengo-kushanda uye kudiwa kwemusika. Munzvimbo huru yekuwana network deployment, yekutanga ndiyo kiyi. Kushandisa ecosystems uye yakakwira-capacity optical tekinoroji inogona kubatsira kuwana mutengo-inoshanda uku ichiwedzera kuvandudza mutengo-unoshanda zvichienderana nekutsvaga uye hunyanzvi.
Nokudaro, kubudirira kwekutengeserana kwe25G PON kuchaenderana nekukwanisa kwayo kupa 2.5 times more bandwidth kupfuura 10G PON pamutengo wakaderera. Sezvineiwo, 25G PON ine nzira inodhura kwazvo yekupfuura 10G PON nekuti ichakwirisa iyo yepamusoro-soro 25G optical tekinoroji inoshandiswa kubatanidza nzvimbo dzedata.
Sezvo data data deployments inowedzera, nhamba ye25G optics ichawedzera uye mutengo wemudziyo uchaderera. Ehe, hazvigoneke kubaya zvakananga izvi data center zvikamu mu optical line kugumiswa (OLT) uye optical network unit (ONU) ma transceivers, ayo anozoda mawavelength matsva, simba rekutumira repamusoro remudhishi, uye kunzwisiswa kwepamusoro kweanogamuchira.
Nekudaro, izvi hazvina kusiyana kubva kuchizvarwa chekare PONs vachishandisa zvikamu kubva kure-haul uye metro transceivers. Uye zvakare, 25G iri nyore TDM tekinoroji isingade inodhura tunable lasers.
Bvisa mamiriro ekushandisa
Nezve kudiwa kwemusika, chinhu chechipiri chinodiwa kuti 25G PON ibudirire ndeyekuona kuti 25G ine zviitiko zvekushandisa zvakajeka, kusanganisira zvekugara, zvekutengesa, nezvimwe zvakadaro. Musika wekugara unogona kupa mukana wekuunganidza maGigabit masevhisi pane yakakwirira-density PONs; munharaunda yekutengeserana, 25G ichapa 10G kana masevhisi epamusoro ekuwedzera masevhisi kumabhizinesi.
Mukuwedzera, nenguva ye5G, kuendesa kure kure kunoda 25G. Kunyange zvazvo XGS-PON kana 10G PTP inogona kunyatsogadzirisa matambudziko epakati uye backhaul, nekuda kwekuwedzera kweRF bandwidth uye MIMO antenna layer, 25G PON inodiwa munyaya yehupamhi hwepamusoro uye yakakwirira single cell throughput. Panguva imwecheteyo, 25G PON inoenderana nenharembozha shanduko nekuti iyo 25G yemuviri interface ichashandiswa kune ese ari pakati uye akagoverwa mayuniti.
Mamwe manzwi
Semazuva ese, indasitiri iri kudzidza dzakasiyana sarudzo dzePON shanduko. Semuenzaniso, 50G PON yakatsanangurwa, asi inopa dambudziko risati rasvika ecosystem risingazogadzirike kusvika 2025, uye parizvino hapana kuoneka mune 50G bhizinesi mamiriro.
Mufananidzo: Zvizvarwa zvinoverengeka zvePON tekinoroji inotsamira pane yakasimbiswa optical uye yemagetsi matekinoroji.
Imwe mhinduro inotariswa ndeyekuita 2x10G bonding pane maviri asina-tunable wavelengths. Mhinduro inoshandisa GPON wavelength uye XGS wavelength. Zvinosuruvarisa, nzira iyi inounza mari yakakwirira (kaviri 10G optics), yakawedzera kuoma, uye kushayikwa kwekukwanisa kugarisana nezvino GPON deployments, saka hapana misika inokwezva.
Dambudziko rakafanana rinogona kuitika neiyo 2xTWDM tunable wavelength bonding nzira. TWDM yatove kudhura zvakanyanya, inoda ma lasers maviri kuti abatanidze wavelengths muneONU, izvo zvinoita kuti mutengo wekutumirwa kukuru uwedzere.
25G PON ndiyo nzira yakanyatso shanda yeku shandurudza fiber-optic network kune chizvarwa chinotevera, nzira iri nyore inoshandisa imwechete wavelength uye haidi yakarongedzwa laser.
Inogara pamwe chete neGPON neXGS-PON uye inopa yakakwirira 25Gb/s kudzika kwemareti uye 25Gb/s kana 10Gb/s mitengo yakakwira. Iyo zvakare yakavakirwa payakasimbiswa optical tekinoroji uye inoshanduka ecosystem inogonesa iyi tekinoroji kuunzwa kumusika nekukurumidza. Inogona kusangana nepamusoro pekugara, zvekutengeserana uye zvimwe zvinodiwa munguva pfupi, apo ichitarisana nekutyisidzira kwemakwikwi e25G EPON uye cable operators.
