Shin ka taɓa yin gunaguni a kanka, "Wannan mummunan hanyar sadarwa ce," alhali haɗin intanet ɗinka yana da jinkiri? A yau, za mu yi magana game da Passive Optical Network (PON). Ba hanyar sadarwa ce "mara kyau" da kake tunani ba, amma dangin jarumai na duniyar hanyar sadarwa: PON.
1. PON, "Jarumi" na Duniyar Sadarwa

PON tana amfani da hanyar sadarwa ta gani gaba ɗaya kuma tsarin shiga haske ne na P2MP (Point to Multiple Point). Yana ba da fa'idodi kamar adana albarkatun fiber, ba tare da buƙatar wutar lantarki ga ODN ba, sauƙaƙe damar shiga mai amfani, da kuma tallafawa damar shiga ayyuka da yawa. Fasaha ce ta hanyar amfani da fiber optic mai yawa wacce masu aiki ke tallata ta a halin yanzu.

3. GPON & EPON
Manyan mambobi biyu da suka fi shahara a cikin dangin fasahar PON sune GPON da EPON.
GPON: Ikon Iyalin PON
GPON, wanda ke wakiltar Gigabit-Capable Passive Optical Network, shine babban ƙarfin gidan PON. Tare da saurin saukarwa har zuwa 2.5 Gbps da saurin saukarwa na 1.25 Gbps, yana ba da sabis na bayanai masu sauri, murya, da bidiyo ga gidaje da kasuwanci. Ka yi tunanin saukar da fim a gida. GPON yana ba ka damar samun saukarwa nan take. Bugu da ƙari, halayen da ba su dace da GPON sun fi dacewa da kasuwar sabis na bayanai na broadband.
EPON: Tauraron Gudu na Iyalin PON
EPON, a takaice ga Ethernet Passive Optical Network, shine tauraron sauri na dangin PON. Tare da saurin daidaitawa na 1.25 Gbps sama da ƙasa, yana tallafawa masu amfani da manyan buƙatun loda bayanai. Daidaiton EPON ya sa ya zama zaɓi mafi kyau ga kasuwanci da masu ƙirƙirar abun ciki waɗanda ke da manyan buƙatun lodawa.
GPON da EPON dukkansu fasahar PON ne, waɗanda suka bambanta musamman a cikin ƙayyadaddun fasaha, ƙimar watsawa, tsarin firam, da hanyoyin rufewa. GPON da EPON kowannensu yana da nasa fa'idodi, kuma zaɓin ya dogara ne akan takamaiman buƙatun aikace-aikace, kasafin kuɗi, da tsarin hanyar sadarwa.
Tare da ci gaban fasaha, bambance-bambancen da ke tsakanin su biyun suna raguwa. Sabbin fasahohi, kamar XG-PON (10-Gigabit-Capable Passive Optical Network) daXGS-PON(10-Gigabit-Capable Symmetric Passive Optical Network), yana ba da saurin gudu da ingantaccen aiki.
Aikace-aikacen Fasaha ta PON
Fasahar PON tana da nau'ikan aikace-aikace iri-iri:
Samun damar intanet ta gida: Yana ba da sabis na intanet mai sauri ga masu amfani da gida, yana tallafawa yawo bidiyo mai inganci, wasannin kan layi, da ƙari.
Cibiyoyin sadarwa na kasuwanci: Samar wa 'yan kasuwa hanyoyin sadarwa masu dorewa, tallafawa manyan ayyuka na watsa bayanai da kuma ayyukan kwamfuta na girgije.
PON ƙwararren mai "wayo ne mai wayo." Saboda yana aiki ba tare da wani amfani ba, farashin gyara yana raguwa sosai. Masu aiki ba sa buƙatar shigar da kayan aiki na wutar lantarki ga kowane mai amfani, wanda hakan ke adana kuɗi mai yawa. Bugu da ƙari, haɓaka hanyar sadarwar PON yana da matuƙar dacewa. Ba a buƙatar haƙa rami; kawai haɓaka kayan aiki a tsakiyar cibiyar zai wartsake dukkan hanyar sadarwar.
