Combo PON Kev daws
Nyob rau hauv xyoo tas los, kev nkag mus cuag broadband cov kev pab tau zoo lawm. Ntawm ib sab tes, qhov kev txhim kho sai ntawm cov kev pabcuam muaj txiaj ntsig xws li 4K TV, 3D games, HD video thiab live-action INTERACTIONS; ntawm qhov tod tes, kev sib tw ua lag luam nruj thiab cov kev cai thoob ntiaj teb kev tsav tsheb, cov neeg siv dav dav ceev kom nkag mus rau kev tsim kho thiab kev xaib kev siv broadband. Lub tshuab hluav taws xob hauv GPON tam sim no maj mam ua tsis tau raws li qhov xav tau ntawm cov kab xev txuas ntxiv ntawm cov kev siv bandwidth. Cov neeg teb xov tooj yuav tsum xav txog cov thev naus laus zis tshiab los muab cov kab ke siab dua, cov kev pabcuam zoo dua, txhim kho cov neeg siv khoom, thiab tsim cov txiaj ntsig tshiab. Thaum GPON hloov kho rau 10G GPON, cov neeg ua haujlwm yuav tsum xav txog ntau yam kev xav tau, suav nrog kev siv rov qab ntawm cov khoom siv uas twb muaj lawm, kev xa tawm sai, thiab teeb meem txuas ntxiv mus thiab rov qab. Lub 10G GPON thev naus laus zis uas tam sim no loj thiab siv kev lag luam tuaj yeem ua tau raws li qhov kev thov no thiab daws qhov kev tsis sib haum ntawm kev txhim kho kev lag luam thiab bandwidth tsis txaus.
GPON hloov kho dua rau 10G GPON muaj ob qho kev daws teeb meem sab nraud Combo PON thiab ib qho kho qhov muag. Sab nrauv multiplexer tov yuav tsum ntxiv OLT thav duab, khib, 10G PON kab daim npav, sab nraud multiplexer, fiber ntau jumper thiab ODF thav duab thiab lwm yam khoom siv txhawb nqa. Cov nqi siv rau kev tsim kho yog qhov siab, qhov chaw ntawm chav khoom siv yog qhov loj, thiab kev tsim kho thiab kev txuas ntawm xaim yog qhov nyuaj heev. Kev tswj hwm thiab txij nkawm nyuaj. Ib qho ntxiv, qhov kho qhov muag hluav taws xob tsis zoo los ntawm sab nraud multiplexer kuj tseem cuam tshuam rau lub hwj chim kho qhov muag ntawm ONU ntawm lub network uas twb muaj lawm, thiab muaj kev pheej hmoo rau cuam tshuam rau cov neeg siv' s kev pabcuam. Ntawm qhov tod tes, kev daws teeb meem Combo PON nrog qhov khoos phis tawm tau muab tso ua ke, thiab GPON thiab 10G GPON optical wavelengths yog dual-channel ua ke hauv ib qho kho qhov muag thiab tso tawm los ntawm tib qhov chaw nres nkoj kho qhov muag. Thaum 10G GPON hloov kho dua tshiab ua, tsuas yog hloov Combo PON kab npav daim npav yog hloov. GPON kab daim npav ntawm daim tseem OLT, daim fiber ntau ntawm daim npav GPON thawj daim npav txiav rau Combo PON kab npav daim npav kom ua tiav qhov kev nyob ua ke ntawm GPON thiab 10G GPON. Txoj kev daws teeb meem rov qab siv ODN thiab cov cuab yeej khoom qub, thiab tsis tas yuav ntxiv cov khoom sib txuas thiab cov khoom siv sab nraud multiplex sab nraud. Piv nrog rau cov kev daws teeb meem sab nrauv, qhov chaw ntawm chav siv khoom me me, qhov kev sib txuas ua ke hauv network yog yooj yim, kev saib xyuas yog yooj yim, thiab cov kev pabcuam tau qhib sai. Nws tsis cuam tshuam rau lub lag luam network uas twb muaj lawm thiab kev nqis peev tag nrho yog qhov me me.
Combo, raws li nws lub npe qhia, yog kev sib txuas ntawm CPON PON, kev sib txuas ntawm GPON thiab 10G GPON, uas siv ob lub thev naus laus zis los siv cov khoom sib txawv wavelengths los sib txuas ob lub yoj yob hauv ib qho kho qhov muag kom tau txais kev ywj pheej ntawm GPON thiab 10G GPON optical teeb liab Cov. Thiab tau txais kev ua tiav, ua tiav nrog cov kev pabcuam GPON network uas twb muaj lawm, thiab muab cov kev pabcuam ua tau zoo ntawm kev thov, rov qab siv cov khoom siv hauv network thiab ODN, zam kev hloov cov khoom siv hauv network thiab qhov chaw ntxiv nyob hauv chav tsev cov khoom siv, thiab hloov cov neeg siv ONUs raws li xav tau rau kev pabcuam cov khoom hloov khoom dua tshiab. Lub davhlau ya nyob twg siv ceev ceev thiab kev txhim kho ntawm cov kev pab cuam-bandwidth.
Lub Combo PON kab daim npav txhawb nqa kab npav daim npav ntawm Combo PON optical module. Koj tuaj yeem hloov daim npav kab ntawm daim ntawv tso tawm GPON OLT nrog Combo PON kab daim npav los txhawm rau txhim kho 10G GPON thiab sai siv cov kev ua haujlwm siab ntawm 10G PON. Combo PON networking architecture yog qhia nyob hauv daim duab 1.
Kev sib xyaw Combo PON tsuas yog yuav tsum tau hloov daim npav npav thiaj li ua tiav qhov kev txhim kho ntawm cov kev pabcuam high-bandwidth. Piv nrog hom nce qib ntawm cov kev daws teeb meem sab nraud multiplexer, nws muaj qhov zoo li nram no:
● Txuag qhov chaw hauv chav khoom siv thiab ua haujlwm yooj yim thiab kho
Kev daws Combo PON tsis tas yuav yuav cov khoom siv sab nraud thiab cov pob ntsig txog. Nyob rau hauv rooj plaub ntawm GPON hloov kho tag nrho, qhov chaw ntawm lub tshuab chav tuaj yeem txuag tau ntau. Piv txwv li, thaum lub khib nyob hauv chav tshuab ua tiav muaj ob lub thawv GPON OLT, yog tias koj xav tau nce mus rau 10G GPON, Combo PON daws tuaj yeem txuag ntau dua 60% ntawm qhov chaw ntawm cov khoom siv hauv chav. Tib lub sijhawm, tsis muaj cov cuab yeej tshiab cuam tshuam nrog cov cuab yeej siv, zam qhov teeb meem ntawm kev ua haujlwm ntau ntxiv thiab kev tswj xyuas, thiab txuag CAPEX thiab OPEX rau cov neeg siv khoom siv dav dav.
● Txo kev nqis peev thaum pib thiab cov nyiaj tau nqes peev
Tus nqi ntawm tam sim no 10G GPON ONU davhlau ya nyob twg yog siab tshaj tus nqi ntawm GPON ONU. Combo PON kev faib tawm kev daws teeb meem tuaj yeem siv los txhim kho ONU ntawm tus neeg siv' s lub tsev raws li xav tau raws li bandwidth txhim kho qhov ua tau ntawm cov neeg siv hauv tsev. Kev xa tawm, zam kev nqis peev siab ntawm lub davhlau ya nyob twg coj ncaj qha los ntawm 10G PON kev txhim kho, thiab sai sai ua tiav qhov nyiaj tshuav ntawm kev nqis peev thiab peev nyiaj
Tsis muaj dab tsi cuam tshuam rau kev pab cuam GPON network uas twb muaj lawm, txhim kho lub network kom zoo
Hauv kev muab cov phiaj xwm loj ntawm GPON cov kev pabcuam hauv lub network uas twb muaj lawm, kev saib xyuas lub zog ntawm qee lub cheeb tsam thiab qee cov neeg siv yuav nruj. Yog tias tus txheej txheem multiplexer sab nraud raug saws, tsawg kawg 1.5dB ntawm cov ntxig nkag yuav tau qhia, thiab muaj kev pheej hmoo tias GPON ONU uas twb muaj lawm yuav tsis ua haujlwm ib txwm muaj. , uas nyob rau hauv lem cuam tshuam rau lub lag luam network uas twb muaj lawm. Kev daws Combo PON yog siv los them rau kev kho qhov muag hluav taws xob poob ntawm qhov sib txuas ntawm cov nthwv dej tom qab lub nthwv dej sab hauv los tsim nyob rau hauv qhov khoos phis tawm kho qhov muag, kom thiaj li paub tseeb tias cov zis ntawm GPON thiab 10G GPON kho qhov muag siv nyiaj tseem tsis hloov pauv. cuam tshuam.
● Txo txo tus nqi ntawm lub chaw haujlwm nruab nrab
Lub Combo PON hloov kho qhov kev daws teeb meem tuaj yeem txo cov nqi xa mus ntawm lub hauv paus chaw ua haujlwm. Txog rau Combo PON thiab sab nraud kev daws teeb meem sab nrauv, peb sib piv cov nqi xa mus rau ntawm lub hauv paus chaw ua haujlwm thiab cov nqi ntawm cov cuab yeej siv rau lub sijhawm 5 xyoo lub neej. Kev daws Combo PON ntau dua li sab nraud ntawm sab nraud multiplexer. Qhov kev zov me nyuam tuaj yeem txuag tau 24% ntawm tus nqi.
Hauv txoj kev xaus, cov neeg ua haujlwm tuaj yeem siv Combo PON kev daws teeb meem kom sai thiab ua tau zoo xa cov kev pabcuam siab, txhim kho cov neeg siv khoom dhau los, txhim kho kev lag luam kev sib tw, thiab tsim kom muaj nuj nqis ntxiv, yog li ua tiav kev txhawb nqa kev lag luam cov txiaj ntsig.
