GPON, aha zuru oke Gigabit-CapablePassive OpticalNetwork, bụ teknụzụ netwọọdụ ngwa anya na-agafe agafe nke mbụ FSAN nzukọ tụpụtara na 2002. Mgbe ọtụtụ afọ nke mmepe gasịrị, ITU-T kwadoro ya na 2003. Teknụzụ GPON bụ tumadi maka ahịa netwọkụ nweta, nke nwere ike. nye data dị elu na nnukwu ike, olu na ọrụ vidiyo maka ezinụlọ na ụlọ ọrụ.
Njirimara teknụzụ GPON bụ ndị a:
1. Ọsọ: ọnụego nnyefe mgbada bụ 2.488Gbps, ọnụego mbufe elu bụ 1.244Gbps.
2. Oke Shunt: 1: 16/32/64.
3. Ogologo nnyefe: Ogologo nnyefe kacha bụ 20km.
4. Usoro ntinye: Jiri GEM (GEM Encapsulation Method) usoro mkpuchi.
5. Usoro nchekwa: Nabata 1 + 1 ma ọ bụ 1: 1 nchebe na-agbanwe agbanwe.
XG-PON, aha zuru oke nke 10Gigabit-CapablePassive OpticalNetwork, bụ ọgbọ na-esote teknụzụ GPON, nke a makwaara dị ka netwọọdụ anya na-ahụ anya na-esote ọgbọ (NG-PON).E jiri ya tụnyere GPON, XG-PON nwere mmụba dị ukwuu na ọsọ ọsọ, nha shunt na ebe nnyefe.
Njirimara teknụzụ XG-PON bụ ndị a:
1. Ọsọ: Ọnụego nnyefe Downlink bụ 10.3125Gbps, ọnụego nnyefe uplink bụ 2.5Gbps (nwekwara ike ịkwalite njikọ elu na 10 GBPS).
2. Oke Shunt: 1: 32/64/128.
3. Ogologo nnyefe: Ogologo nnyefe kacha bụ 20km.
4. Usoro ngwugwu: Jiri usoro ngwugwu GEM/10GEM.
5.Protection usoro: Nabata 1 + 1 ma ọ bụ 1: 1 nchebe na-agbanwe agbanwe.
XGS-PON, nke a maara dị ka 10GigabitSymmetric Passive OpticalNetwork, bụ ụdị symmetric nke XG-PON, emebere iji nye ọrụ ịnweta brọdband yana ọnụego mgbago elu na mgbada ala.Tụnyere XG-PON, XGS-PON nwere nnukwu mmụba na ọsọ elu.
Njirimara teknụzụ XGS-PON bụ ndị a:
1. Ọsọ: Ọnụego nnyefe nke ala bụ 10.3125Gbps, ọnụego nnyefe elu bụ 10 GBPS.
2. Oke Shunt: 1: 32/64/128.
3. Ogologo nnyefe: Ogologo nnyefe kacha bụ 20km.
4. Usoro ngwugwu: Jiri usoro ngwugwu GEM/10GEM.
5. Usoro nchekwa: Nabata 1 + 1 ma ọ bụ 1: 1 nchebe na-agbanwe agbanwe.
Mkpebi: GPON, XG-PON na XGS-PON bụ teknụzụ netwọkụ anya na-agafe agafe atọ.Ha nwere ọdịiche doro anya na ọsọ ọsọ, nha shunt, nnyefe nnyefe, wdg, iji gboo mkpa nke ọnọdụ ngwa dị iche iche.
Kpọmkwem: GPON bụ tumadi maka ahịa netwọk ohere, na-enye nnukwu ọsọ, data ike, olu na vidiyo na ọrụ ndị ọzọ;XG-PON bụ ụdị GPON emelitere, yana oke ọsọ yana oke shunt na-agbanwe agbanwe.XGS-PON na-emesi akara ngosi nke elu na ọnụego mgbada ma dabara maka ngwa netwọkụ ọgbọ na ndị ọgbọ.Ịghọta isi ọdịiche dị n'etiti teknụzụ atọ a na-enyere anyị aka ịhọrọ ngwọta netwọk anya ziri ezi maka ọnọdụ dị iche iche.
