Kodi mudadzidandaulira nokha, "Iyi ndi netiweki yoyipa," intaneti yanu ikachedwa? Lero, tikambirana za Passive Optical Network (PON). Simaneti "oyipa" omwe mumawaganizira, koma banja lapamwamba lapaintaneti: PON.
1. PON, "Wopambana" wa Network World
PONimatanthawuza maukonde a fiber optic omwe amagwiritsa ntchito mfundo-to-multipoint topology ndi optical splitters kuti atumize deta kuchokera kumalo amodzi opatsirana kupita kumalo angapo ogwiritsira ntchito. Muli ndi optical line terminal (OLT), optical network unit (ONU), ndi optical distribution network (ODN). PON imagwiritsa ntchito netiweki yapang'onopang'ono yofikira ndipo ndi njira ya P2MP (Point to Multiple Point). Imapereka maubwino monga kusunga zida za fiber, kusafuna mphamvu ku ODN, kuwongolera mwayi wogwiritsa ntchito, komanso kuthandizira kupeza ntchito zambiri. Ndi ukadaulo wa Broadband Fiber Optic Access womwe ukulimbikitsidwa kwambiri ndi ogwiritsa ntchito.
PON ili ngati "Ant-Man" yapadziko lonse lapansi yapaintaneti: yaying'ono koma yamphamvu kwambiri. Imagwiritsa ntchito fiber optical ngati njira yotumizira ndikugawa ma siginecha owoneka kuchokera ku ofesi yapakati kupita kumalo angapo ogwiritsa ntchito kudzera pazida zopanda ntchito, zomwe zimathandizira kuthamanga kwambiri, kothandiza, komanso zotsika mtengo zofikira mabroadband.
Tangoganizani ngati dziko la intaneti likanakhala ndi ngwazi, PON ikanakhala Superman wosadziwika. Sichifuna mphamvu ndipo imatha "kuwuluka" pa intaneti, kubweretsa chidziwitso cha intaneti chofulumira ku mabanja masauzande ambiri.
2. Ubwino wa PON's Core
Imodzi mwa "mphamvu zazikulu" za PON ndikutumiza kwake mwachangu. Poyerekeza ndi ma netiweki amkuwa amkuwa, PON imagwiritsa ntchito ulusi wa kuwala, zomwe zimapangitsa kuti pakhale kuthamanga kwambiri.
Tangoganizani kutsitsa kanema kunyumba, ndipo nthawi yomweyo imawonekera pa chipangizo chanu ngati matsenga. Kuphatikiza apo, kuwala kwa fiber kumagwirizana ndi kugunda kwa mphezi ndi kusokonezedwa ndi ma elekitiroma, ndipo kukhazikika kwake sikungafanane.
3. GPON & EPON
Mamembala awiri odziwika bwino a banja laukadaulo la PON ndi GPON ndi EPON.
GPON: Mphamvu ya Banja la PON
GPON, kuyimira Gigabit-Capable Passive Optical Network, ndi mphamvu ya banja la PON. Ndi liwiro lotsika mpaka 2.5 Gbps ndi liwiro la uplink la 1.25 Gbps, limapereka chidziwitso chothamanga kwambiri, champhamvu kwambiri, mau, ndi makanema ku nyumba ndi mabizinesi. Tangoganizani kutsitsa kanema kunyumba. GPON imakulolani kuti muzitha kutsitsa pompopompo.Komanso, mawonekedwe a GPON asymmetric amatha kusinthana ndi msika wa data wa burodibandi.
EPON: Nyenyezi Yothamanga ya PON Family
EPON, mwachidule cha Ethernet Passive Optical Network, ndi nyenyezi yothamanga ya banja la PON. Ndi ma symmetrical 1.25 Gbps kumtunda ndi kumtunda kuthamanga, imathandizira bwino ogwiritsa ntchito omwe ali ndi zosowa zazikulu zokweza deta. EPON's symmetry imapangitsa kukhala chisankho choyenera kwa mabizinesi ndi opanga zomwe zili ndi zofunika zazikulu zokweza.
GPON ndi EPON onse ndi matekinoloje a PON, amasiyana makamaka muukadaulo, mitengo yotumizira, mawonekedwe azithunzi, ndi njira zolumikizira. GPON ndi EPON aliyense ali ndi ubwino wake, ndipo kusankha kumadalira zofunikira za ntchito, bajeti yamtengo wapatali, ndi kukonzekera maukonde.
Ndi kupita patsogolo kwaukadaulo, kusiyana pakati pa ziwirizi kukucheperachepera. Tekinoloje zatsopano, 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.
Mapulogalamu a PON Technology
Ukadaulo wa PON uli ndi ntchito zingapo:
Kufikira kunyumba kwa burodibandi: Amapereka mautumiki apaintaneti othamanga kwambiri kwa ogwiritsa ntchito kunyumba, kuthandizira kutsitsa kwamakanema omveka bwino, masewera a pa intaneti, ndi zina zambiri.
Maukonde abizinesi: Perekani mabizinesi okhala ndi ma netiweki okhazikika, othandizira kutumizirana ma data akulu akulu ndi ntchito zamakompyuta apamtambo.
PON ndi wochenjera "wopereka chikho." Chifukwa chakuchita, ndalama zosamalira zimachepetsedwa kwambiri. Ogwiritsa ntchito safunikiranso kukhazikitsa ndi kukonza zida zamagetsi kwa aliyense wogwiritsa ntchito, kupulumutsa ndalama zambiri. Kuphatikiza apo, kukweza kwa netiweki ya PON ndikosavuta kwambiri. Palibe kukumba kofunikira; kungokweza zida pakatikati pa node kumatsitsimutsa maukonde onse.
Mizinda ya Smart: Pomanga mzinda wanzeru, ukadaulo wa PON umatha kulumikiza masensa osiyanasiyana ndi zida zowunikira, kupangitsa mayendedwe anzeru, kuyatsa kwanzeru, ndi matekinoloje ena.
