Muchikamu cheNetwork yekutaurirana yanhasi, tekinoroji yePassiveOptical Network (PON) yave kutora nzvimbo yakakosha zvishoma nezvishoma munetwork huru yekutaurirana nemabhenefiti ayo ekumhanya kwakanyanya, kureba kure uye kusava neruzha. Pakati pawo, GPON, XG-PON neXGS-PON ndidzo tekinoroji dzinonyanya kutariswa dzepassive optical network. Dzine hunhu hwadzo uye dzinoshandiswa zvakanyanya mumamiriro akasiyana. Chinyorwa chino chinoongorora misiyano mikuru pakati pematekinoroji matatu aya zvakadzama kuti vaverengi vanzwisise zviri nani maficha awo uye mamiriro ekushandisa.
GPON, zita rakazara rekuti Gigabit-CapablePassive OpticalNetwork, itekinoroji ye network ye optical passive yakatangwa nesangano reFSAN muna 2002. Mushure memakore akati wandei ekugadzirwa, ITU-T yakaigadzirisa zviri pamutemo muna 2003. Tekinoroji yeGPON inonyanya kushandiswa pamusika we network ye access, iyo inogona kupa masevhisi e data, izwi nemavhidhiyo anokurumidza uye ane simba guru kumhuri nemabhizinesi.
Zvimiro zvetekinoroji yeGPON ndeizvi:
1. Kumhanya: mwero wekutumirwa kwedata pasi pemvura ndeye 2.488Gbps, mwero wekutumirwa kwedata kumusoro kwemvura ndeye 1.244Gbps.
2. Chiyero cheShunt: 1:16/32/64.
3. Kureba kwekutumira: kureba kwakanyanya kwekutumira i20km.
4. Maitiro ekuisa zvidimbu muzvikamu: Shandisa maitiro ekuisa zvidimbu muzvikamu zveGEM (GEM Encapsulation Method).
5. Nzira yekudzivirira: Shandisa nzira yekushandura yekudzivirira isina simba ye1+1 kana 1:1.
XG-PON, zita rakazara re10Gigabit-CapablePassive OpticalNetwork, ichizvarwa chinotevera chetekinoroji yeGPON, inozivikanwawo sechizvarwa chinotevera chenetwork yemagetsi isingashande (NG-PON). Kana ichienzaniswa neGPON, XG-PON ine shanduko huru mukumhanya, chiyero cheshunt uye daro rekutumira.
Zvimiro zvetekinoroji yeXG-PON ndeizvi:
1. Kumhanya: Mwero wekutumira data reDownlink i10.3125Gbps, mwero wekutumira data reuplink i2.5Gbps (uplink inogonawo kukwidziridzwa kusvika pa10 GBPS).
2. Chiyero cheShunt: 1:32/64/128.
3. Kureba kwekutumira: kureba kwakanyanya kwekutumira i20km.
4. Magadzirirwo epakeji: Shandisa magadzirirwo epakeji eGEM/10GEM.
5. Nzira yekudzivirira: Shandisa nzira yekushandura 1+1 kana 1:1 isina simba.
XGS-PON, inozivikanwa se10GigabitSymmetric Passive OpticalNetwork, ishanduro yeXG-PON yakafanana, yakagadzirirwa kupa masevhisi ekuwana broadband ane mwero wakaenzana wepamusoro nepasi. Kana ichienzaniswa neXG-PON, XGS-PON ine kuwedzera kukuru kwekumhanya kweuplink.
Zvinhu zvetekinoroji yeXGS-PON ndeizvi:
1. Kumhanya: Mwero wekutumirwa kwedata pasi pemvura ndeye 10.3125Gbps, mwero wekutumirwa kwedata repasi pemvura ndeye 10 GBPS.
2. Chiyero cheShunt: 1:32/64/128.
3. Kureba kwekutumira: kureba kwakanyanya kwekutumira i20km.
4. Magadzirirwo epakeji: Shandisa magadzirirwo epakeji eGEM/10GEM.
5. Nzira yekudzivirira: Shandisa nzira yekushandura yekudzivirira isina simba ye1+1 kana 1:1.
Mhedziso: GPON, XG-PON uye XGS-PON matekinoroji matatu akakosha e network ye optical passive. Ane musiyano uri pachena mukumhanya, shunt ratio, daro rekutumirwa, nezvimwewo, kuti agutse zvinodiwa nemamiriro akasiyana ekushandisa.
Zvikuru: GPON inonyanya kushandiswa pamusika we network yekupinda, ichipa data rinokurumidzira, rine simba guru, izwi nemavhidhiyo nemamwe masevhisi; XG-PON ishanduro yakagadziridzwa yeGPON, ine kumhanya kwakanyanya uye shunt ratio inochinjika. XGS-PON inosimbisa kuenzana kwemitengo yepamusoro neyepasi uye yakakodzera maapplication e network ye peer-to-peer. Kunzwisisa misiyano mikuru pakati pematekinoroji matatu aya kunotibatsira kusarudza mhinduro yakakodzera ye network ye optical yezviitiko zvakasiyana.
