Ku China, 100M Optical Broadband yakhala yotchuka, ndipo nthawi ya Gigabit yatsala pang'ono kutsegulidwa.Mu 2019, Ministry of Industry and Information Technology inayambitsa ntchito ya "Double G Double Lifting, Same Network Same Speed" pa intaneti, ndipo ikupitiriza kupititsa patsogolo kupititsa patsogolo mapulogalamu a Gigabit okhazikika. megabytes" mpaka "gigabit".Ukadaulo wa 10G GPON umanena zaukadaulo monga XG-PON, XG-PON & GPON Combo, XGS-PON, XGS-PON & GPON Combo.Chisinthiko ku 10G GPON chiyenera kuganizira zokhudzana ndi ma ONU osiyanasiyana.
Pofuna kuthetsa vuto lomwe XG-PON siligwirizana ndi GPON ONU, ZTE ndiye woyamba kupereka ukadaulo wa Combo PON kuti azindikire XG-PON & GPON Combo. zolandilidwa ndi ogwiritsa ntchito chifukwa chogwirizana bwino komanso zosavuta.Yakhala njira yothetsera 10G GPON yomanga ndipo imapezeka pamalonda pamlingo waukulu.
Tsopano teknoloji ya XGS-PON yakhala yokhwima, ndipo XGS-PON ikhoza kupereka 10G ya kumtunda ndi kumtunda kwa symmetric bandwidth, koma XGS-PON OLT ikhoza kugwirizana ndi XGS-PON ndi XG-PON mitundu iwiri ya ONU, pamene chiwerengero chachikulu cha GPON ndi ONU amatumizidwa mu maukonde alipo, ndi ngakhale kwa maukonde alipo GPON ndi ONU ayenera kuthetsedwa pamene maukonde evolved kuti XGS-PON.Kuti athetse vutoli, ZTE akufuna atatu mlingo Combo luso, ndicho XGS-PON. ndi GPON kukhazikitsa Combo, yomwe imathandizira kukweza bwino kwa GPON kupita ku XGS-PON.
Mfundo yaukadaulo ya Combo PON yamitundu itatu
XGS-PON&GPON's Combo PON solution ndi njira yopangira ma multiplexer yomwe imathandizira XGS-PON/XG-PON/GPON njira zitatu zokhalira limodzi. njira yabwino kwambiri yosinthira GPON kukhala XGS-PON.
Combo PON yamitundu itatu imagwiritsa ntchito mfundo zamatali osiyanasiyana onyamula ma XGS-PON ndi GPON matekinoloje, ndikuphatikiza mafunde awiri mu gawo limodzi la kuwala kuti azindikire kutumiza kodziyimira pawokha ndikulandila kwa GPON ndi XGS-PON ma siginecha owoneka. PON Optical module ili ndi chophatikizira chophatikizidwa chomwe chingaphatikize mafunde anayi okwera ndi pansi omwe amafunikira kuti agawanike XGS-PON ndi GPON.XGS-PON ndi XG-PON amagwiritsa ntchito kutalika kwake komweko, komwe kumakhala kutalika kwa 1270 nm ndi kutsika kwamtsinje. kutalika kwa 1577 nm.GPON kumagwiritsa ntchito 1310nm kumtunda kwamtunda ndi 1490nm kutsika kwamtunda kwamtunda, ndipo mawonekedwe atatu a Combo PON optical module amazindikira kutumiza ndi kukonzanso kwa fiber imodzi-wavelength (onani Chithunzi 1).
Combo PON yamitundu itatu imapereka kuthekera kwa ma terminals a GPON ogwirizana.Chifukwa chaukadaulo wa WDM, bandwidth yoperekedwa ndi doko la PON ndi kuchuluka kwa bandwidth ya njira za XGS-PON ndi GPON. GPON terminal, downlink bandwidth yoperekedwa ndi doko lililonse la PON ndi 12.5 Gbps (10 Gbps + 2.5 Gbps), ndipo bandwidth ya uplink ndi 11.25 Gbps (10 Gbps + 1.25 Gbps).
Yankho la ZTE lamitundu itatu ya Combo PON
ZTE's Combo PON board yamitundu itatu itenga 8/16-port XGS-PON&GPON dual-channel hardware design.Doko limodzi la Combo PON likufanana ndi ma PON MAC awiri (GPON MAC ndi XGS-PON MAC) ndi njira ziwiri zakuthupi (WDM1r ikuphatikizidwa mu module ya kuwala).Mu njira yochepetsera, mafunde awiri apansi amasinthidwa ndi PON MAC yosiyana, yotumizidwa ku module ya kuwala kwa multiplexing, ndiyeno imatumizidwa ku ONU zosiyanasiyana.XGS-PON ONU imalandira chizindikiro cha XGS-PON, ndipo XG-PON ONU imalandira XG.- Chizindikiro cha PON, GPON ONU imalandira chizindikiro cha GPON. Pamalo okwera pamwamba, GPON ndi XGS-PON amagwiritsa ntchito mafunde osiyanasiyana, zosefera poyamba mu gawo la kuwala, ndiyeno zimapanga njira zosiyanasiyana za MAC. XGS-PON ndi XG-PON zimagwiritsa ntchito kutalika kwake komweko. ndipo muyenera kupanga DBA ndandanda pa njira yomweyo.
Nambala ya doko la Combo PON khadi ndi madoko 8 kapena 16.Maonekedwe ndi mawonekedwe a thupi ndi amodzi-modzi.Izi zimathandizira kasamalidwe ka tsiku ndi tsiku ndi kukonza kwa chipangizocho komanso kasamalidwe kazinthu. Mukakonza data yoyang'anira maukonde, muyenera kuwonjezera mtundu watsopano wa bolodi, ndikuwerengera ma GPON, XG-PON, ndi XGS-PON ONU kuti muzindikire Mtundu wa ONU ndikusintha kanjira.Popeza kuti doko la Combo PON lothamanga katatu limafanana ndi njira ziwiri zakuthupi, njira zowongolera zowongolera ndi izi: Doko la Combo PON limaphatikizapo njira ziwiri zakuthupi: GPON ndi XGS-PON.Ziwerengero za kagwiridwe ka ntchito ndi kasamalidwe ka alamu ziyenera kuwonjezedwa kutengera MIB yoyambirira (Management Information Base).
Poyambira kupeza chidziwitso modziyimira pawokha pamayendedwe a GPON ndi XG (S) -PON, ndikofunikira kupeza chidziwitso cha njira ziwiri zakuthupi panthawi imodzi.
Ma MIB okhudzana ndi machitidwe ena a ntchito ndi kasamalidwe ka ntchito ndi kukonza sikusintha.Amasinthidwa kukhala doko la Combo PON, ndipo Combo PON imangosinthira kunjira.
Kutsogola pakupanga kwa 10G PON
Combo PON yothamanga katatu imatha kupeza XGS-PON, XG-PON ndi GPON mitundu itatu ya ONU pakufunika, yomwe imatha kukwaniritsa zosowa za ogwiritsa ntchito osiyanasiyana: XGS-PON itha kugwiritsidwa ntchito kwa ogwiritsa ntchito aboma ndi mabizinesi, ndi XG. -PON itha kugwiritsidwa ntchito kwa ogwiritsa ntchito Home Gigabit, GPON imagwiritsidwa ntchito pakupeza olembetsa 100M wamba.
Poyerekeza ndi chiwembu chakunja chochulukitsa, zabwino za Combo PON yamitundu itatu ndizodziwikiratu:
Palibe chifukwa chosinthira ODN, ntchitoyi ndi yosavuta.Pamene multiplexer kunja ntchito ntchito, m`pofunika kuonjezera chipangizo multiplexer, ndipo m`pofunika kusintha maukonde ODN pa mlingo waukulu, zimene n`zovuta kukhazikitsa mu uinjiniya, chomwe ndi chimodzi mwa zifukwa zazikulu chifukwa XG-PON ndi. zovuta kukwera.
Kutayika kwatsopano koyikirako sikunayambitsidwe, ndipo vuto la maginito amagetsi amathetsedwa kwathunthu.Kugwiritsiridwa ntchito kwa multiplexer kunja kudzawonjezera kutayika kowonjezera kwa 1 ~ 1.5db, zomwe mosakayikira zimakhala zoipitsitsa kwa bajeti zambiri za magetsi opangira magetsi omwe ali olimba kale, ndipo pulojekitiyi siingatheke. .Pamene mulingo wofanana wa optical module umakhazikitsidwa, Combo PON imayambitsidwa, ndipo malire a bajeti yamagetsi a ODN sasintha.
Sungani malo mu chipinda cha makina ndi kuphweka ntchito ndi kukonza.Magawo atatu othamanga a Combo PON optical module amagwirizanitsa ntchito monga XG (S) -PON, GPON, ndi WDM1r.Sichimawonjezera zida zowonjezera ndipo sichikhala ndi malo owonjezera a chipinda, kumathandizira kukonza ndi kuyang'anira.
OSS ndi yosavuta kuyika, njira yotsegulira sikusintha, ndipo mzere wapamwamba umadulidwa.Combo PON yothamanga katatu imagwiritsa ntchito WDM mode.XG(S)-PON tchanelo ndi GPON tchanelo zimangofanizidwa ndi mitundu yawo yotsiriza.XG (S) -PON ndi GPON zomwe zilipo kale zimagwirizanitsidwa ndi OSS, ndipo njira yotsegulira utumiki imakhala yosasinthika.Zosavuta kutsegula, polojekitiyi ndi yosavuta kudula.
Njira zitatu za Combo PON zalandira chidwi chochuluka kuchokera kwa ogwira ntchito ambiri monga Orange, Telefonica ndi China Mobile.Kutengera yankho la Combo PON ndi machitidwe akuluakulu ogulitsa malonda, ZTE adagwira nawo ntchito yoyesa katatu ya Combo PON ndi mchitidwe wamalonda wa ogwira ntchito ambiri, ndipo anapitiriza kutsogolera 10G GPON yomangamanga.
