AON vs PON Networks: Zosankha za Fiber-to-the-Home FTTH Systems

Fiber to the Home (FTTH) ndi dongosolo lomwe limayika ma fiber optics kuchokera pakatikati molunjika m'nyumba monga nyumba ndi nyumba. Kutumiza kwa FTTH kwafika patali kwambiri ogwiritsa ntchito asanatenge ma fiber optics m'malo mwa mkuwa kuti apeze intaneti.

Pali njira ziwiri zoyambira kugwiritsa ntchito netiweki yothamanga kwambiri ya FTTH:ma network owoneka bwino(AON) ndi kungokhala cheteoptical network(PON).

Chifukwa chake ma AON ndi ma PON network: pali kusiyana kotani?

Kodi network ya AON ndi chiyani?

An AON ndi malo opangira maukonde omwe amalembetsa aliyense ali ndi mzere wake wa fiber optic womwe umathetsedwa pa optical concentrator. netiweki ya AON imaphatikizapo zida zosinthira zamagetsi zamagetsi monga ma routers kapena ma switching aggregators kuti azitha kuyang'anira kugawa kwazizindikiro ndi kusaina kolowera kwa makasitomala enaake.

Zosintha zimatsegulidwa ndi kuzimitsa m'njira zosiyanasiyana kuti ziwongolere zizindikiro zomwe zimalowa ndi zotuluka kumalo oyenerera.Kudalira kwa AON network pa teknoloji ya Ethernet kumapangitsa kuti kugwirizana pakati pa opereka chithandizo kukhale kosavuta. Olembetsa amatha kusankha zida zomwe zimapereka mitengo yoyenera ya data ndikukulitsa momwe zosowa zawo zikuchulukira popanda kukonzanso maukonde. Komabe, maukonde a AON amafunikira chosinthira chimodzi pa olembetsa.

Kodi network ya PON ndi chiyani?

Mosiyana ndi ma netiweki a AON, PON ndi makina opangira ma point-to-multipoint omwe amagwiritsa ntchito ma splitter kuti alekanitse ndikusonkhanitsa ma siginecha owoneka. Zigawo za fiber zimalola kuti PON network itumikire olembetsa angapo mu ulusi umodzi popanda kufunikira kuyika ulusi wosiyana pakati pa hub ndi wogwiritsa ntchito kumapeto.

Monga momwe dzinalo likusonyezera, maukonde a PON samaphatikizapo zida zosinthira zamagalimoto ndikugawana ma fiber pagawo la netiweki. Zida zogwira ntchito zimangofunika pa gwero ndi kulandira mapeto a chizindikiro.

Mu netiweki wamba ya PON, chogawa cha PLC ndiye chimayambira. Ma tap a fiber optic amaphatikiza ma siginecha angapo kuti atulutse kumodzi, kapena matepi a fiber optic amatenga cholumikizira chimodzi ndikuchigawa kuzinthu zingapo. Makapu awa a PON ali ndi njira ziwiri. Kunena zomveka, ma siginecha a fiber optic amatha kutumizidwa pansi kuchokera ku ofesi yapakati kuti akaulutse kwa onse olembetsa. Zizindikiro zochokera kwa olembetsa zitha kutumizidwa kumtunda ndikuphatikizidwa kukhala ulusi umodzi kuti mulankhule ndi ofesi yapakati.

AON vs PON Networks: Kusiyana ndi Zosankha

Ma network onse a PON ndi AON amapanga msana wa fiber optic wa FTTH, kulola anthu ndi mabizinesi kupeza intaneti. Musanasankhe PON kapena AON, ndikofunika kumvetsetsa kusiyana pakati pawo.

Kugawa kwa Signal

Pankhani ya AON ndi PON maukonde, kusiyana kwakukulu pakati pawo ndi momwe chizindikiro cha kuwala chimagawidwira kwa kasitomala aliyense mu dongosolo la FTTH. Mu dongosolo la AON, olembetsa adzipatulira mitolo ya fiber, yomwe imawathandiza kukhala ndi mwayi wofanana ndi bandwidth, osati kugawana nawo. Mu netiweki ya PON, olembetsa amagawana gawo la network fiber bundle mu PON. Zotsatira zake, anthu omwe amagwiritsa ntchito PON angapezenso kuti machitidwe awo akuchedwa chifukwa ogwiritsa ntchito onse amagawana bandwidth yomweyo. Ngati vuto limapezeka mkati mwa dongosolo la PON, zingakhale zovuta kupeza gwero la vutoli.

Mtengo

Mtengo waukulu kwambiri womwe umapitilira pa netiweki ndi mtengo wopangira zida zamagetsi ndi kukonza. PON imagwiritsa ntchito zida zomwe zimafunikira kusamalidwa pang'ono komanso zopanda magetsi kuposa netiweki ya AON, yomwe ndi netiweki yogwira. Chifukwa chake PON ndiyotsika mtengo kuposa AON.

Kutalikirana Kwakutali ndi Ntchito

AON imatha kuyenda mtunda wa makilomita 90, pomwe PON nthawi zambiri imakhala ndi mizere ya chingwe cha fiber optic mpaka ma kilomita 20. Izi zikutanthauza kuti ogwiritsa ntchito a PON akuyenera kukhala pafupi ndi chizindikirocho.

Kuphatikiza apo, ngati ikugwirizana ndi ntchito kapena ntchito inayake, palinso zinthu zina zingapo zomwe ziyenera kuganiziridwa. Mwachitsanzo, ngati ntchito za RF ndi makanema ziyenera kutumizidwa, ndiye kuti PON nthawi zambiri ndiyo yankho lokhalo. Komabe, ngati ntchito zonse zili pa Internet Protocol, ndiye kuti PON kapena AON zingakhale zoyenera. Ngati mtunda wautali ukukhudzidwa ndikupereka mphamvu ndi kuziziritsa kuzinthu zomwe zikugwira ntchito m'munda zitha kukhala zovuta, ndiye kuti PON ikhoza kukhala chisankho chabwino kwambiri. Kapena, ngati makasitomala omwe akufuna kukhala nawo ndi malonda kapena polojekitiyi ikuphatikizapo malo okhalamo ambiri, ndiye kuti intaneti ya AON ikhoza kukhala yoyenera.

AON vs. PON Networks: Ndi FTTH iti yomwe mumakonda?

Posankha pakati pa PON kapena AON, ndikofunikira kuganizira zomwe zidzaperekedwe pamanetiweki, ma topology onse pamanetiweki, ndi omwe makasitomala oyambira ndi ndani. Ogwiritsa ntchito ambiri agwiritsa ntchito kusakanikirana kwa maukonde onsewa munthawi zosiyanasiyana. Komabe, pamene kufunikira kwa kugwirizanirana kwa maukonde ndi scalability kukukulirakulirabe, ma network architecture akuloleza kuti ulusi uliwonse ugwiritsidwe ntchito mosinthana mu PON kapena AON applications kuti zikwaniritse zofunikira zamtsogolo.
