1) Lub ntsiab lus:
Nrog kev tshwm sim sai ntawm ntau lub lag luam, ntau thiab ntau kev lag luam paub tias nws yog qhov yuav tsum tau tawg los ntawm "bottleneck" ntawm bandwidth sai li sai tau, thiab cov fiber ntau optical yog nyob deb ntawm qhov zoo tshaj plaws kis nruab nrab. Optical fiber ntau muaj ob qhov zoo ntawm cov tooj liab hlau: kev sib kis ntev dua; Ntau cov ntaub ntawv raug xa mus rau ib lub sijhawm (txog 100tbps / s tam sim no).
Hoob no tsuas yog kawm txog keeb kwm yav dhau los, cov ntsiab lus tseem ceeb, cov yam ntxwv, kev siv cov xwm txheej ntawm GPON thev naus laus zis, hom kev tswj hwm ntawm GPON system thiab cov kev pabcuam faib hom ntawm lub davhlau ya nyob twg, nrog rau kev sib txuas lus thiab kev tiv thaiv kev sib txuas ntawm GPON.
2) Lub tswv yim
PON yog passive optical network nrog ib tug taw tes rau multipoint (p2mp) qauv;
GPON: Gigabit-muaj peev xwm passive optical network. Kev sib xyaw ntawm PON network: optical kab davhlau ya nyob twg (OLT)
Optical distribution network (ODN) yog tsim los ntawm optical splitter thiab optical fiber
Optical network unit/terminalonu/ont (optical network unit / kho qhov muag network davhlau ya nyob twg)
Cov txheej txheem kis tau tus mob yog raws li nram no:
OLTuplink txuas nrog Is Taws Nem, VoIP, IPTV, thiab downlink txuas nrog ODN;
ODN faib tag nrho cov ntaub ntawv rau txhua tusONUlos yog ont los ntawm optical faib;
ONUlos yog ont lim tawm cov ntaub ntawv lawv xav tau los ntawm tus lej cim hauv cov ntaub ntawv, thiab tom qab ntawd xa mus rau tus neeg siv.
Cov saum toj no yog GPON network architecture coj los ntawm Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. Cov khoom lag luam tsim los ntawm lub tuam txhab npog optical fiber modules, Ethernet modules, optical fiber ntau transceiver modules, optical fiber nkag modules, SSFP optical modules, thiabSFP optical fibers, thiab lwm yam. Cov khoom lag luam saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Ib pab neeg R & D muaj zog thiab muaj zog tuaj yeem pab cov neeg siv khoom nrog cov teeb meem kev lag luam, thiab pab pawg ua lag luam muaj kev xav thiab kev ua haujlwm tuaj yeem pab cov neeg siv khoom tau txais kev pabcuam zoo thaum lub sijhawm sib tham ua ntej thiab ua haujlwm tom qab tsim khoom. Zoo siab txais tos koj tiv tauj pebrau txhua yam kev nug.
