(1) 10G PON Technology nzira yekuvandudza
EPON inotongwa neIEEE, uye GPON inotungamirwa neITU zvese zviri kushanduka kusvika pagumi GPON nhanho parizvino uye kuronga kunotevera zvese 100G PON. Pane mimwe misiyano munzira dzakanangana dzekushanduka, uye nzira inoenderana yekushanduka inoratidzwa mumufananidzo unotevera:
(2) EPON tekinoroji shanduko
Iyo 10G EPON symmetric uye asymmetric technical zviyero uye zvigadzirwa zvakave zvakakwana, Pamusoro pezvo, ine mukana wekugara pamwe neEPON terminal mune imwecheteyo ODN network pasina kuwedzera multiplexer. Mushure mekutenga kwepakati kweOLTmuna 2016, OLT's 10G PON Optical modules dzakaderedzwa mumutengo.
. Tichifunga nezve shanduko yeramangwana retiweki, vashandisi vakatanga kugadzira 10G EPON pachine nguva pakupera kwenzvimbo, uye vachiri kushandisa EPON ONT mumutengi kuita FTTH kuvaka. Panguva imwecheteyo, nokuti mutsauko wemutengo pakati pe symmetric optical module uye asymmetric optical module haisi yakakura, uye tichifunga nezvehuwandu hwehuwandu hwehuwandu hwehuwandu hwe10G EPON kumusoro uye kuzasi kwemvura ndeye 1: 10, kuitira kuti udzivise kudiwa kwekusimudzira kunokonzerwa neanotevera. uplink sevhisi yekusimudzira, vashandisi vanonyanya kuda kuendesa 10G EPON symmetric mode muOLTside. Nhanho inotevera yeEPON ichashanduka yakananga ku100G PON tekinoroji.
(3) GPON tekinoroji shanduko
Kune iyo 10G GPON yakajairwa, iyo asymmetric XG-PON tekinoroji mwero uye zvigadzirwa zvave zvakakwana. The fixed wavelength symmetric 10G GPON standard XGS-PON yakabudiswa muna February 2016. Pamusana pezvigadzirwa zvakakura zvakabatanidzwa muhutano, zvimwe zvigadzirwa zvevagadziri zvakagadzirira kushandiswa kwekutengeserana. Iyo NGPON2 (TWDMPON) chiyero ine inochinjika wavelength yakave yakakwana. Parizvino,OLTzvigadzirwa zvave zvichitengeswa muEurope neAmerica. Panguva imwecheteyo, kune zvinoenderana neMDU zvigadzirwa zvebhizimusi rakatsaurirwa mutsara musika. Iyo optical module ine inogadziriswa wavelength yeNGPON2 inodhura uye yakaoma kuwana.Mushure mekunge ITU yawedzera symmetrical fixed wavelength 10G standard (XGS-PON), vamwe vanogadzira vanotenda kuti NGPON2 inogona kusvetuka uye yakananga kushanduka kune 4 * 25G 100G PON mhinduro, uye zvinokwanisika kubatanidza ne100G EPON chiyero.
Munguva pfupi, mutengo weONT we10G PON hauzowira kumutengo uripo weEPON / GPON, saka hazvidzivisiki kutarisana nemamiriro ezvinhu ekugara pamwe kwe10 GPON uye mushandisi rutivi rweEPON / GPON terminal. Nekuti GPON uye XGPON zviteshi zvinogara mune imwecheteyo ODN network, WDM1r modules inoda kuwedzerwa, iyo inomisa kutumirwa kweXG-PON mune yazvino network. Nokudaro, vagadziri vanobatsira vane Combo PON chirongwa che encapsulate GPON uye XGPON optical modules uye WDM1r mune imwe optical module. Nekudaro, iyo optical module yeCombo PON chirongwa inogona kungoiswa neXFP, uye iyo imwechete bhodhi inogona kungoona 8 PON ports (yakajairika.SFP+ kurongedza, uye bhodhi rimwe chete rinogona kuona gumi nematanhatu PON ports). Zvichakadaro, nekuda kwekuwedzera kweWDM1r kuisa kurasikirwa, simba rinopenya rinodiwa re optical modules rakakwirira. Parizvino, simba rinopenya reB +/N1 rinogona kuitika chete, uye iyo C +/N2a yakakwira simba module haigone kupihwa munguva pfupi, iyo inodzikamisa mashandisirwo emakure-akareba makuru e spectral ratio.
Izvo zviri pamusoro ndiyo tsananguro yeEPON uye tekinoroji shanduko. Zvigadzirwa zvetiweki zveShenzhen HDV photoelectron Technology Co., Ltd. zvese zvigadzirwa zvinogadzirwa zvakatenderedza PON network, kusanganisiraONUseries/OLTseries / optical module series / transceiver series uye zvichingodaro. Kuti tigadzire yakanakisa network michina, kambani yedu yakashongedzerwa neboka rehunyanzvi rekutsvagisa nekusimudzira, kupa vatengi vane emhando yepamusoro hunyanzvi hwekutsigira masevhisi, kugamuchirwa kukuda vashandi kuti vanzwisise zvigadzirwa zvedu.
