Tekinoloje ya PON nthawi zonse imakhala ndi kuthekera kodzikonzanso ndikusinthira kumisika yatsopano.Kuchokera pa liwiro la mbiri mpaka kuwirikiza kawiri ndi ma lambda angapo, PON yakhala "ngwazi" ya Broadband, zomwe zimathandizira kufalikira kwa ntchito zatsopano.Kupititsa patsogolo bizinesi ndizotheka.
Pamene intaneti ya 5G ikuyamba kupanga, nkhani ya PON ikutsegulanso tsamba latsopano.Nthawi ino, teknoloji ya PON ya m'badwo wotsatira ikugwiritsa ntchito paradigm yatsopano kuti ikwaniritse mphamvu zapamwamba. njira yotumizira yomwe imagwiritsidwa ntchito m'mbiri ya teknoloji ya PON, yomwe ikuyimira gawo lotsatira la kusintha kwa fiber, gawo latsopano mu nkhani ya PON.
Kutsika mtengo ndiye chinsinsi
Pali zinthu ziwiri zofunika kuti mupeze luso laukadaulo: kutsika mtengo komanso kufunikira kwa msika.Pakutumizidwa kwa netiweki yayikulu, choyambirira ndiye chinsinsi.Kugwiritsa ntchito zachilengedwe zotsimikiziridwa ndi matekinoloje apamwamba kwambiri atha kuthandizira kukwaniritsa zotsika mtengo pomwe kupititsa patsogolo kukwera mtengo kutengera kafukufuku ndi luso.
Choncho, kupambana kwa malonda a 25G PON kudzadalira mphamvu yake yopereka maulendo a 2.5 kuposa 10G PON pamtengo wotsika.Mwamwayi, 25G PON ili ndi njira yotsika mtengo kwambiri yopitira 10G PON chifukwa idzagwiritsa ntchito luso lapamwamba la 25G Optical lomwe limagwiritsidwa ntchito kulumikiza malo opangira deta.
Pamene kutumizidwa kwa deta kumawonjezeka, chiwerengero cha 25G optics chidzawonjezeka ndipo mtengo wa chipangizocho udzachepa.Zoonadi, sizingatheke kulumikiza mwachindunji zigawo za data center mu optical line termination (OLT) ndi optical network unit (ONU) transceivers, zomwe zidzafunika mafunde atsopano, mphamvu zotumizira kwambiri za transmitter, ndi kukhudzika kwakukulu kwa wolandira.
Komabe, izi sizosiyana ndi ma PON a m'badwo wam'mbuyomu omwe amagwiritsa ntchito zida zakutali ndi ma transceivers a metro.Kuphatikiza apo, 25G ndiukadaulo wosavuta wa TDM womwe sufuna ma lasers okwera mtengo.
Chotsani mawonekedwe ogwiritsira ntchito
Ponena za kufunikira kwa msika, chinthu chachiwiri chofunikira kuti 25G PON chipambane ndikuwonetsetsa kuti 25G ili ndi zochitika zomveka zogwiritsira ntchito, kuphatikizapo nyumba, malonda, ndi zina zotero.Msika wokhalamo ungapereke mwayi wophatikiza ntchito za Gigabit pa ma PON apamwamba kwambiri;mu gawo lazamalonda, 25G idzapereka 10G kapena mautumiki apamwamba kuti awonjezere ntchito ku malonda.
Kuphatikiza apo, ndi nthawi ya 5G, kutumizirana mtunda wautali kumafuna 25G.Ngakhale XGS-PON kapena 10G PTP ikhoza kuthetsa bwino mavuto apakati ndi obwerera kumbuyo, chifukwa cha kuwonjezeka kwa RF bandwidth ndi MIMO antenna wosanjikiza, 25G PON ikufunika pa nkhani ya kachulukidwe kakang'ono komanso kutulutsa kwa selo limodzi.Panthawi imodzimodziyo, 25G PON ikugwirizana ndi kusintha kwa mafoni a m'manja chifukwa mawonekedwe a 25G adzagwiritsidwa ntchito pamagulu onse apakati komanso ogawidwa.
Zomveka zina
Monga mwachizolowezi, makampaniwa akuphunzira njira zingapo zosinthira PON.Mwachitsanzo, 50G PON yaperekedwa, koma imabweretsa zovuta zachilengedwe zomwe sizingasinthe mpaka 2025, ndipo pakali pano palibe kuwoneka mu bizinesi ya 50G.
Chithunzi: Mibadwo ingapo yaukadaulo wa PON imadalira matekinoloje otsimikizika amagetsi ndi magetsi.
Njira inanso yomwe imaganiziridwa ndikugwirizanitsa 2x10G pamafunde awiri osasunthika.Yankho limagwiritsa ntchito GPON wavelength ndi XGS wavelength.Mwamwayi, njirayi imabweretsa ndalama zambiri (kawiri 10G optics), kuwonjezereka kwa zovuta, komanso kusowa kwa mphamvu yogwirizana ndi kutumizidwa kwa GPON zamakono, kotero palibe malonda a msika.
Vuto lofananalo litha kuchitika ndi njira yolumikizira ya 2xTWDM tunable wavelength.TWDM ndiyokwera kale kwambiri, ikufuna ma lasers awiri kuti agwirizane ndi kutalika kwa mafunde mu ONU, zomwe zimapangitsa kuti mtengo wa kutumiza kwakukulu ukhale wokwera kwambiri.
25G PON ndiyo njira yabwino kwambiri yosinthira netiweki ya fiber-optic kupita ku m'badwo wotsatira, njira yosavuta yomwe imagwiritsa ntchito utali wamtundu umodzi ndipo sichifuna laser yokonzedwa.
Imakhala limodzi ndi GPON ndi XGS-PON ndipo imapereka mitengo yotsika kwambiri ya 25Gb/s ndi 25Gb/s kapena 10Gb/s mitengo yokwera kumtunda.Zimakhazikitsidwanso paukadaulo waukadaulo wotsimikiziridwa komanso chilengedwe chosinthika chomwe chimathandizira ukadaulo uwu kubweretsedwa pamsika mwachangu.Ikhoza kukwaniritsa zosowa zapamwamba zokhalamo, zamalonda ndi zina panthawi yochepa, pamene zikulimbana ndi chiopsezo cha mpikisano wa 25G EPON ndi oyendetsa chingwe.
