Shin kun taɓa yin kuka ga kanku, "Wannan mugunyar hanyar sadarwa ce," lokacin da haɗin intanet ɗin ku ya yi jinkiri? Yau, za mu yi magana ne game da Passive Optical Network (PON). Ba cibiyar sadarwar "mummuna" ba ce kuke tunani ba, amma dangin superhero na duniyar cibiyar sadarwa: PON.
1. PON, "Babban Jarumi" na Duniyar Sadarwa
PONyana nufin hanyar sadarwa ta fiber optic da ke amfani da ma'ana-zuwa-multipoint topology da masu rarrabawar gani don watsa bayanai daga wurin watsawa guda ɗaya zuwa wuraren ƙarshen masu amfani da yawa. Ya ƙunshi tashar tashar tashoshin gani (OLT), naúrar hanyar sadarwa ta gani (ONU), da cibiyar sadarwa ta rarrabawar gani (ODN). PON yana amfani da hanyar sadarwa ta hanyar samun dama ta gani gaba ɗaya kuma ita ce tsarin samun damar gani na gani P2MP (Point to Multiple Point). Yana ba da fa'idodi kamar adana albarkatun fiber, buƙatar rashin ƙarfi ga ODN, sauƙaƙe samun damar mai amfani, da tallafawa samun dama ga sabis da yawa. Fasaha ce ta hanyar sadarwa ta fiber optic access a halin yanzu da masu aiki ke tallata su.
PON yana kama da "Ant-Man" na duniyar sadarwar: ƙarami amma mai ban mamaki. Yana amfani da fiber na gani azaman matsakaicin watsawa kuma yana rarraba sigina na gani daga ofishin tsakiya zuwa maƙallan masu amfani da yawa ta hanyar na'urori masu wucewa, yana ba da damar sabis mai sauri, inganci, da ƙarancin farashi.
Ka yi tunanin idan duniyar hanyar sadarwar tana da babban jarumi, PON tabbas zai zama Superman da ba a bayyana ba. Ba ya buƙatar iko kuma yana iya "tashi" a cikin duniyar kan layi, yana kawo ƙwarewar Intanet mai sauri ga dubban gidaje.
2. Abubuwan Amfanin PON
Ɗayan "mafi ƙarfi" na PON shine watsa saurin haske. Idan aka kwatanta da hanyoyin sadarwar waya na jan ƙarfe na gargajiya, PON yana amfani da fiber na gani, yana haifar da saurin watsawa cikin sauri.
Ka yi tunanin zazzage fim ɗin a gida, kuma nan take ya bayyana akan na'urarka kamar sihiri. Bugu da ƙari, fiber na gani yana da juriya ga faɗakarwar walƙiya da tsangwama na lantarki, kuma kwanciyar hankalinsa ba ya misaltuwa.
3. GPON & EPON
Shahararrun mambobi biyu na dangin fasahar PON sune GPON da EPON.
GPON: Ikon Iyalin PON
GPON, Tsaya ga Gigabit-Capable Passive Optical Network, shine gidan wutar lantarki na dangin PON. Tare da saurin saukarwa har zuwa 2.5 Gbps da haɓakawa na 1.25 Gbps, yana ba da babban sauri, manyan bayanai, murya, da sabis na bidiyo zuwa gidaje da kasuwanci. Ka yi tunanin zazzage fim a gida. GPON yana ba ku damar dandana abubuwan zazzagewa nan take. Bugu da ƙari, halayen asymmetric na GPON sun fi dacewa da kasuwar sabis na bayanai na broadband.
EPON: Tauraron Saurin Iyalin PON
EPON, takaice don Ethernet Passive Optical Network, shine tauraron gudun dangin PON. Tare da madaidaicin 1.25 Gbps sama da saurin ƙasa, yana goyan bayan masu amfani da manyan buƙatun loda bayanai. Misalin EPON ya sanya ya zama kyakkyawan zaɓi don kasuwanci da masu ƙirƙirar abun ciki tare da manyan buƙatun loda.
GPON da EPON duka fasahar PON ne, sun bambanta da farko a cikin ƙayyadaddun fasaha, ƙimar watsawa, tsarin firam, da hanyoyin ɗaukar hoto. GPON da EPON kowanne yana da nasa fa'idodin, kuma zaɓin ya dogara da takamaiman buƙatun aikace-aikacen, kasafin kuɗi, da kuma tsarin hanyar sadarwa.
Tare da ci gaban fasaha, bambance-bambancen da ke tsakanin su biyu yana raguwa. Sabbin fasahohi, kamar XG-PON (10-Gigabit-Cable Passive Optical Network) daXGS-PON(10-Gigabit-Cable Symmetric Passive Optical Network), yana ba da saurin gudu da ingantaccen aiki.
Aikace-aikacen Fasaha na PON
Fasahar PON tana da aikace-aikace da yawa:
Samun hanyar sadarwa ta gida: Yana ba da sabis na intanit mai sauri ga masu amfani da gida, yana goyan bayan kwararar bidiyo mai girma, wasan kan layi, da ƙari.
Cibiyoyin kasuwanci: Samar da kasuwanci tare da tsayayyen haɗin yanar gizo, tallafawa manyan watsa bayanai da sabis na lissafin girgije.
PON "mai wayo ne mai wayo." Saboda yana da m, ana rage farashin kulawa sosai. Masu aiki ba sa buƙatar sakawa da kula da kayan wuta ga kowane mai amfani, adana kuɗi mai yawa. Bugu da ƙari, haɓaka hanyar sadarwar PON yana da matukar dacewa. Ba a buƙatar tonowa; kawai haɓaka kayan aiki a kumburin tsakiya zai wartsake duk hanyar sadarwa.
Garuruwan wayo: A cikin ginin birni mai wayo, fasahar PON na iya haɗa na'urori masu auna firikwensin daban-daban da kayan aikin sa ido, ba da damar sufuri mai hankali, haske mai wayo, da sauran fasahohi.
