Plaub Yuav Tsum Tau Txhawb Nqa Cov Kev Loj Hlob PLC
Qhov kev thov ntawm PLC tsis kho qhov muag twj yeem yog nce rau cov ntaub ntawv xa xov, yog li txhawb txoj kev loj hlob ntawm PLC technology, mas yog ntawm plaub qhov chaw yuav tsum tau teev muaj hauv qab no.
1. Lub Siab Los Ntawm Kev Sib Txuas Xov Tooj Network
Broadband subscribers yog nce nrog kev loj hlob tus nqi ntawm 20-30% toj ib xyoo, nruab nrab kev loj hlob ntawm ib tus neeg tauj ib xyoo txog 20-30%. Nws yog kwv yees hais tias nyob rau hauv 2014 qhov nruab nrab bandwidth yuav los ntawm qhov tam sim no 2M loj hlob mus rau ntau tshaj 20M, kev loj hlob nyob rau hauv lag luam volume ntws ntawm tsib xyoos txog 10 lub sij hawm.
Cov ntaub ntawv qhia tau hais tias, CTC qaum kev lag luam ntawm IP txhua xyoo kev loj hlob ntawm 40% -50% hauv tsib xyoos tom ntej no, tag nrho cov kev siv bandwidth ntawm kev lag luam kis kab mob yuav nce tawm ntawm 64Tbps mus txog 120-155Tbps, txawm tias 200Tbps. Kev sib txuas lus network ntawm kev tawm tsam tau kis mus rau txheej pob qaum ntawm kev saib txheej, thiab yuav npaj tawm ib qho kev kho dua tshiab ntawm kev sib koom ua lag luam.
Nrog kev nce siab ntawm kev sib koom tes network sib txuas lus, optical tes hauj lwm thiab kev thauj xa mus kom dav siv WDM DWDM. Tam sim no, South Korea tus coob mobile carrier SK Telecom siv DWDM khoom ntawm Nokia Siemens, siv hiT 7300 DWDM platform, ib txhij xa 80 channel wavelength, tib lub wavelength tuaj yeem thauj cov ntaub ntawv 100G, kom tag nrho cov muaj peev xwm ntawm fiber ntau optic mus txog 8 Tbps.
Nyob hauv keeb kwm ntawm txoj kev loj hlob ntawm kev loj hlob nyob rau hauv cov kev pabcuam tshiab rau cov kev pabcuam tshiab thiab NX 40Gb / s WDM network scale deployment, tshiab N x 100Gb / s WDM txhawb zog loj dua qub rau kev ua haujlwm ntawm cov khoom siv bandwidth yav tom ntej.
100G WDM kev ua lag luam yuav muaj kev ruaj ntseg ntxiv nyob rau tsib xyoos tom ntej no. Nyob rau lub Ib Hlis 2013 Dell'Oro kho qhov muag pom kev ua lag luam qhia, tsib xyoo tom ntej no, lub ntiaj teb WDM lag luam yuav loj hlob ntawm tus nqi txhua xyoo ntawm 10%, yuav mus txog $ 13 billion los ntawm 2017. Dell'Oro hais tias, 40G / 100G ua kev loj hlob rau yav tom ntej; thiab tau txais txiaj ntsig los ntawm kev loj hlob hauv 40G / 100G WDM qhov kev thov, hauv tsib xyoos tom qab cov lag luam fiber ntau qhov muag yuav tshwm sim zuj zus ntxiv. Raws li cov kev lag luam yog nce rau ntawm cov khoom siv network, 100G kev thov ua lag luam yuav muaj zog tshwj xeeb.
Kev nce nqi ntawm cov ntaub ntawv sib hloov yog loj heev ntawm kev txo hwj chim noj, kev sib txuas lus kev lag luam kev lag luam, kev lag luam kom muaj zog ntawm 100G, tag nrho nce cov xav tau ntawm PLC cov khoom tsis taus.
2. Txoj Kev Loj Hlob ntawm Cov Ntaub Ntawv Nrov Loj
Raws li Cisco tsab ntawv ceeb toom, tshaj 2011-2016 xyoos, lub ntiaj teb cov ntaub ntawv chaw tsheb khiav yuav nce plaub zaug, ntiaj teb huab ndlwg yuav nce rau lub sijhawm. Los ntawm 2016 yuav muaj 2/3 cov ntaub ntawv chaw tsheb khiav tawm ntawm cov kev pabcub huab. Huab computing yuav ua rau ob txoj kev khiav hauv cov ntaub ntawv chaw.
Piv rau qhov chaw zov me nyuam cov ntaub ntawv, ib lub hauv paus txheej xwm cov ntaub ntawv nquag ntawm huab xam data center yog li 4 zaug, 8 npaug los yog ntau dua 10 zaug raws li cov ntaub ntawv chaw zov me nyuam cov ntaub ntawv.
Yuav kom txo qeeb lag luam, txhawm rau kom muaj kev teb ceev ceev ntawm cov ntaub ntawv network, huab nruab data center tub ntxhais siv network 40G / 100G chaw nres nkoj.
3. Nkag mus rau Tsev Kawm Ntawv - Naiskhu txuas kev sib txuas ntawm PON Technology
Kev sib txuas ntawm tes hauj lwm sib koom tes yog kev sib txuas lus sib txuas lus, xov tooj cua thiab Internet network tsim ua ke, ua kom tiav network nrog kev koom tes, kev sib koom siv, muab cov neeg siv suab, cov ntaub ntawv thiab tso tawm TV thiab lwm yam kev pab. PON tshuab cov khoom siv yog siv rau FTTH thiab Triple tes hauj lwm convergence. Lub WDM-PON PON combines qhov zoo ntawm WDM technology thiab PON qauv, tab tom ua qhov kev kawm siab. Qhov nruab nrab no kuj tau siv cov khoom PLC splitter.
4. Lub Silicon Chip Fiber Interconnection
Microelectronics tab tom ntsib cov kev sib tw ntawm RC bottleneck thiab cov teeb meem cua sov. Nti thiab nti interconnect ceev ntawm 6-8Gbps, 32nm, 22nm, tooj liab thiab tooj liab interconnect ceev ntawm 15nm, 11nm, 7nm. Thaum nyob rau hauv 10nm tshwm sim quantum teebmeem, ntau tshaj 20Gbps xav tau fiber ntau interconnection. Piv txwv, Intel Si launched ib qhov kev sib txuas ntawm photonic nti, nti sib txuas siv WDM, vim qhov hluav taws xob interconnection yog kim, hluav taws xob interconnection maj evolved rau fiber ntau interconnection tau los ua ib qho kev tsis pom nriav.
Nyob rau hauv xaus, yuav tsum siv cov fiber ntau kis tau siv hluav taws xob kis mus rau lwm qhov chaw, thiab yog ib qho kev sib tshuam optical kis tau yooj yim, kev sib tsoo 100G WDM backbone network, 40G / 100G data centers, FTTH access networks, chip optical interconnect muaj txhawb qhov kev loj hlob ntawm PLC kho qhov muag pab kiag li lawm. Thiab lub nti yuav siv nyob rau hauv WDM thiab PLC splitter, kev ua daim tawv cheb ntau dua los mus saib nyiaj loj thiab kev siv zog, siv PLC hybrid kev koom ua ke, SOI silicon photonics, InP PIC kev koom ua ke thiab lwm yam technologies. Cov kev cai no yuav txhawb txhua txoj kev loj hlob thiab kev hloov ntawm PLC technology.
