Kodi munayamba mwadandaulapo kuti, "Iyi ndi netiweki yoipa kwambiri," pamene intaneti yanu ikuchedwa? Lero, tikambirana za Passive Optical Network (PON). Si netiweki "yoyipa" yomwe mumaganizira, koma banja la ngwazi zapadziko lonse la netiweki: PON.
1. PON, "Ngwazi Yaikulu" ya Network World
PONimatanthauza netiweki ya fiber optic yomwe imagwiritsa ntchito topology ya point-to-multipoint ndi optical splitters kuti itumize deta kuchokera ku malo amodzi otumizira deta kupita ku ma endpoint angapo a ogwiritsa ntchito. Ili ndi optical line terminal (OLT), optical network unit (ONU), ndi optical distribution network (ODN). PON imagwiritsa ntchito netiweki yolowera ya optical yopanda ntchito ndipo ndi njira yolowera ya P2MP (Point to Multiple Point). Imapereka zabwino monga kusunga zinthu za fiber, osafuna mphamvu ya ODN, kuthandizira ogwiritsa ntchito kupeza, komanso kuthandizira mwayi wopeza ntchito zambiri. Ndi ukadaulo wa broadband fiber optic womwe ukulimbikitsidwa ndi ogwiritsa ntchito.
PON ili ngati "Ant-Man" wa dziko la maukonde: yaying'ono koma yamphamvu kwambiri. Imagwiritsa ntchito ulusi wa kuwala ngati njira yotumizira mauthenga ndipo imagawa zizindikiro za kuwala kuchokera ku ofesi yayikulu kupita ku malo ambiri ogwiritsira ntchito kudzera muzipangizo zopanda ntchito, zomwe zimathandiza kuti ntchito zolumikizirana ndi intaneti zikhale zothamanga kwambiri, zogwira mtima, komanso zotsika mtengo.
Tangoganizirani ngati dziko la maukonde likanakhala ndi ngwazi, PON ikanakhala Superman wosatchuka kwambiri. Sichifuna mphamvu ndipo imatha "kuuluka" padziko lonse la pa intaneti, zomwe zimapangitsa kuti mabanja ambiri azikumana ndi intaneti mwachangu.
2. Ubwino Waukulu wa PON
Chimodzi mwa "mphamvu zazikulu" za PON ndi kutumiza kwake mwachangu. Poyerekeza ndi maukonde achikhalidwe a waya wamkuwa, PON imagwiritsa ntchito ulusi wowala, zomwe zimapangitsa kuti kutumiza kukhale kothamanga kwambiri.
Tangoganizirani kutsitsa kanema kunyumba, ndipo nthawi yomweyo imawonekera pa chipangizo chanu ngati matsenga. Kuphatikiza apo, ulusi wa kuwala umalimbana ndi mphezi ndi kusokonezedwa ndi maginito, ndipo kukhazikika kwake sikungafanane.
3. GPON & EPON
Mamembala awiri odziwika bwino a banja la ukadaulo wa PON ndi GPON ndi EPON.
GPON: Mphamvu ya Banja la PON
GPON, yomwe ikuyimira Gigabit-Capable Passive Optical Network, ndiye malo amphamvu kwambiri m'banja la PON. Ndi liwiro la downlink la 2.5 Gbps ndi liwiro la uplink la 1.25 Gbps, imapereka ntchito za data, mawu, ndi makanema mwachangu kwambiri m'nyumba ndi m'mabizinesi. Tangoganizirani kutsitsa kanema kunyumba. GPON imakulolani kuti muzitha kutsitsa nthawi yomweyo. Kuphatikiza apo, mawonekedwe a GPON osagwirizana amatha kusinthidwa mosavuta pamsika wa data ya broadband.
EPON: Nyenyezi Yothamanga ya Banja la PON
EPON, mwachidule cha Ethernet Passive Optical Network, ndi nyenyezi ya liwiro la banja la PON. Ndi liwiro lofanana la 1.25 Gbps la pamwamba ndi pansi, limathandiza bwino ogwiritsa ntchito omwe akufuna kukweza deta yayikulu. Kufanana kwa EPON kumapangitsa kuti ikhale chisankho chabwino kwambiri kwa mabizinesi ndi opanga zinthu omwe akufuna kukweza zambiri.
GPON ndi EPON zonse ndi ukadaulo wa PON, wosiyana makamaka mu specifications zaukadaulo, kuchuluka kwa ma transmission, kapangidwe ka chimango, ndi njira zolumikizira. GPON ndi EPON iliyonse ili ndi ubwino wake, ndipo kusankha kumadalira zofunikira zinazake zogwiritsira ntchito, bajeti ya ndalama, ndi kukonzekera netiweki.
Ndi kupita patsogolo kwa ukadaulo, kusiyana pakati pa ziwirizi kukuchepa. Maukadaulo atsopano, monga XG-PON (10-Gigabit-Capable Passive Optical Network) ndiXGS-PON(10-Gigabit-Capable Symmetric Passive Optical Network), imapereka liwiro lapamwamba komanso magwiridwe antchito abwino.
Kugwiritsa Ntchito Ukadaulo wa PON
Ukadaulo wa PON uli ndi ntchito zosiyanasiyana:
Kufikira pa intaneti pa intaneti kunyumba: Kumapereka ntchito za intaneti yothamanga kwambiri kwa ogwiritsa ntchito kunyumba, kuthandizira kuwonera makanema apamwamba, masewera apa intaneti, ndi zina zambiri.
Ma network a mabizinesi: Amapereka mabizinesi ma network okhazikika, kuthandizira kutumiza deta yayikulu komanso ntchito zowerengera deta pa intaneti.
PON ndi "wogwira ntchito wanzeru." Chifukwa chakuti siigwira ntchito nthawi zonse, ndalama zokonzera zimachepetsedwa kwambiri. Ogwiritsa ntchito safunikanso kuyika ndi kusamalira zida zamagetsi za wogwiritsa ntchito aliyense, zomwe zimapulumutsa ndalama zambiri. Kuphatikiza apo, kukweza netiweki ya PON ndikosavuta kwambiri. Sikofunikira kufukula; kungokweza zida pamalo apakati kudzatsitsimutsa netiweki yonse.
Mizinda yanzeru: Pakumanga mizinda yanzeru, ukadaulo wa PON ukhoza kulumikiza masensa osiyanasiyana ndi zida zowunikira, zomwe zimathandiza mayendedwe anzeru, magetsi anzeru, ndi ukadaulo wina.
