(1) Njira yachitukuko ya 10G PON Technology
EPON yolamulidwa ndi IEEE, ndi GPON yolamulidwa ndi ITU onse akusintha mpaka 10 GPON stage pakali pano ndipo kukonzekera kotsatira ndi 100G PON. Pali kusiyana kwina m'njira zachisinthiko, ndipo njira yofananira yachisinthiko ikuwonetsedwa pachithunzi chotsatirachi:
(2) Chisinthiko chaukadaulo wa EPON
10G EPON symmetric and asymmetric technical standards and products have been angwiro, Komanso, ili ndi ubwino wokhala ndi EPON terminal mu ODN network yomweyo popanda kuwonjezera multiplexer. Pambuyo pa zogula zapakati zaOLTmu 2016, ma module a OLT a 10G PON adachepetsedwa pamtengo.
. Poganizira za kusinthika kwamtsogolo kwa maukonde, ogwira ntchito anayamba kupanga 10G EPON pasadakhale kumapeto kwa m'deralo, ndipo adagwiritsabe ntchito EPON ONT mwa kasitomala kuti agwire ntchito yomanga FTTH. Pa nthawi yomweyi, chifukwa kusiyana kwa mtengo pakati pa symmetric optical module ndi asymmetric Optical module sikuli kwakukulu, ndipo kuganizira chiwerengero cha bandwidth cha 10G EPON kumtunda ndi kumtunda ndi 1: 10, pofuna kupewa kuwonjezereka kowonjezereka komwe kumayambitsidwa ndi zotsatira zotsatila. chitukuko cha ntchito za uplink, ogwiritsira ntchito amakonda kuyika 10G EPON symmetric mode muOLTmbali. Gawo lotsatira la EPON lisintha kupita kuukadaulo wa 100G PON.
(3) Chisinthiko chaukadaulo wa GPON
Pa mulingo wa 10G GPON, mulingo waukadaulo wa XG-PON wa asymmetric ndi zogulitsa zakhala zangwiro. The fixed wavelength symmetric 10G GPON standard XGS-PON inatulutsidwa mu February 2016. Chifukwa cha zipangizo zokhwima zomwe zimakhudzidwa ndi muyezo, zinthu zina za opanga zimakhala zokonzeka kugulitsa malonda. Muyezo wa NGPON2 (TWDMPON) wokhala ndi kutalika kosinthika wapangidwa kukhala wangwiro. Pakadali pano,OLTZogulitsa zakhala zikugulitsidwa ku Europe ndi America.Panthawi yomweyo, pali zinthu zofananira za MDU pamsika wodzipereka wamabizinesi. The optical module with adjustable wavelength of NGPON2 ndi okwera mtengo komanso zovuta kukwaniritsa.ITU itawonjezera symmetrical fixed wavelength 10G standard (XGS-PON), opanga ena amakhulupirira kuti NGPON2 ikhoza kudumpha ndikusintha mwachindunji ku 4 * 25G 100G PON yankho, ndipo ndizotheka kuphatikiza ndi muyezo wa 100G EPON.
M'kanthawi kochepa, mtengo wa ONT wa 10G PON sudzagwera pamtengo wamtengo wapatali wa EPON / GPON, choncho n'zosapeŵeka kukumana ndi kukhalapo kwa 10 GPON ndi EPON / GPON terminal. Chifukwa ma terminals a GPON ndi XGPON amakhala mu netiweki yomweyo ya ODN, ma module a WDM1r akuyenera kuwonjezeredwa, zomwe zimalepheretsa kutumizidwa kwa XG-PON mumaneti omwe alipo. Choncho, opanga opindulitsa ali ndi ndondomeko ya Combo PON ya encapsulate GPON ndi XGPON optical modules ndi WDM1r mu module imodzi ya kuwala. Komabe, gawo la Optical la Combo PON scheme limatha kuikidwa ndi XFP, ndipo gulu limodzi limatha kuzindikira madoko 8 a PON (zachilendo.SFP+ kulongedza, ndipo bolodi limodzi limatha kuzindikira madoko 16 a PON). Panthawiyi, chifukwa cha kuwonjezeka kwa kutayika kwa WDM1r, mphamvu zowala zowunikira ma modules optical ndi apamwamba. Pakadali pano, mphamvu yowala ya B +/N1 imatha kuzindikirika, ndipo gawo lamphamvu la C +/N2a silingaperekedwe kwakanthawi kochepa, komwe kumachepetsa kugwiritsa ntchito mawonekedwe akutali kwambiri.
Zomwe zili pamwambazi ndizofotokozera za EPON ndi kusintha kwa teknoloji. Zogulitsa pa netiweki za Shenzhen HDV photoelectron Technology Co., Ltd. zonse ndi zida zopangidwa mozungulira PON network, kuphatikizaONUmndandanda /OLTmndandanda / kuwala module mndandanda / transceiver mndandanda ndi zina zotero. Pofuna kupanga zida zabwino kwambiri zopezera maukonde, kampani yathu ili ndi gulu lofufuza ndi chitukuko la akatswiri, kuti apatse makasitomala chithandizo chamankhwala apamwamba kwambiri, olandilidwa kuti azifuna antchito kuti amvetsetse malonda athu.
