Mundima yemazuva ano yeNetiweki yekukurukurirana, PassiveOptical Network (PON) tekinoroji zvishoma nezvishoma yakatora chinzvimbo chakakosha munharembozha yekutaurirana ine zvakanakira kumhanya, kureba uye pasina ruzha.Pakati pavo, GPON, XG-PON uye XGS-PON ndiwo anonyanya kunetseka passive optical network tekinoroji.Vane maitiro avo uye anoshandiswa zvakanyanya muzviitiko zvakasiyana.Ichi chinyorwa chinoongorora misiyano yakakosha pakati peaya matatu matekinoroji zvakadzama kubatsira vaverengi kunzwisisa zviri nani maitiro avo uye mamiriro ekushandisa.
GPON, zita rakazara Gigabit-CapablePassive OpticalNetwork, is a passive optical network tekinoroji yakatanga kukurudzirwa nesangano reFSAN muna 2002. Mushure memakore akati wandei ebudiriro, ITU-T yakaimisa zviri pamutemo muna 2003. Tekinoroji yeGPON inonyanya kushandiswa kwemusika wekuwana network, unogona inopa yakakwirira-kumhanya uye yakakura-inogonesa data, izwi uye vhidhiyo masevhisi emhuri nemabhizinesi.
GPON tekinoroji maficha ndeaya anotevera:
1. Kukurumidza: kuderera kwekufambisa kwepamusoro ndeye 2.488Gbps, kukwira kwepamusoro kwekutengesa chiyero ndeye 1.244Gbps.
2. Shunt ratio: 1:16/32/64.
3. Kuendesa kure: kureba kwekufambisa kureba ndeye 20km.
4. Encapsulation format: Shandisa GEM (GEM Encapsulation Method) encapsulation format.
5. Nzira yekudzivirira: Adopt 1 + 1 kana 1: 1 passive protection switching mechanism.
XG-PON, zita rakazara re10Gigabit-CapablePassive OpticalNetwork, ndiyo inotevera chizvarwa cheGPON tekinoroji, inozivikanwawo sechizvarwa chinotevera passive optical network (NG-PON).Kuenzaniswa neGPON, XG-PON ine kuvandudzwa kwakakura mukumhanya, shunt ratio uye kureba kwekutapurirana.
XG-PON tekinoroji maficha ndeaya anotevera:
1. Speed: Downlink transmission rate ndeye 10.3125Gbps, uplink transmission rate ndeye 2.5Gbps (uplink inogonawo kukwidziridzwa kusvika ku10 GBPS).
2. Shunt ratio: 1:32/64/128.
3. Kuendesa kure: kureba kwekufambisa kureba ndeye 20km.
4. Package format: Shandisa GEM/10GEM purogiramu yepakiti.
5.Protection mechanism: Adopt 1 + 1 kana 1: 1 passive protection switching mechanism.
XGS-PON, inozivikanwa se10GigabitSymmetric Passive OpticalNetwork, ishanduro inoenzanirana yeXG-PON, yakagadzirirwa kupa masevhisi ekupinda mubroadband ane symmetric kumusoro nekudzika kwemitengo.Kuenzaniswa neXG-PON, XGS-PON ine kuwedzera kukuru kwekumhanya kwekukwira.
XGS-PON tekinoroji maficha ndeaya anotevera:
1. Kukurumidza: Kuyerera kwepasi kwepasi ndeye 10.3125Gbps, iyo yepamusoro-soro yekufambisa chiyero ndeye 10 GBPS.
2. Shunt ratio: 1:32/64/128.
3. Kuendesa kure: kureba kwekufambisa kureba ndeye 20km.
4. Package format: Shandisa GEM/10GEM purogiramu yepakiti.
5. Nzira yekudzivirira: Adopt 1 + 1 kana 1: 1 passive protection switching mechanism.
Mhedziso: GPON, XG-PON uye XGS-PON ndiwo matatu akakosha passive optical network tekinoroji.Ivo vane misiyano iri pachena mukumhanya, shunt reshiyo, kureba kwekufambisa, nezvimwe, kusangana nezvinodiwa zveakasiyana mashandisirwo mamiriro.
Kunyanya: GPON inonyanya kumusika wekuwana network, inopa kukurumidza-kumhanya, data yakakura, izwi uye vhidhiyo uye mamwe masevhisi;XG-PON ivhezheni yakakwidziridzwa yeGPON, ine kumhanya kwepamusoro uye yakanyanya kuchinjika shunt ratio.XGS-PON inosimbisa symmetry yekukwira nekudzika kwemazinga uye inokodzera peer-to-peer network application.Kunzwisisa misiyano yakakosha pakati peaya matatu matekinoroji kunotibatsira kusarudza iyo chaiyo optical network mhinduro yemamiriro akasiyana.
