ʻO XG-PON a me XGS-PON nā mea ʻelua i ka moʻo GPON, a mai ka palapala alanui ʻenehana, ʻo XGS-PON ka hoʻomohala ʻenehana o XG-PON.
ʻO XG-PON a me XGS-PON ʻelua 10G PON, ʻo nā ʻokoʻa nui: ʻo XG-PON ka asymmetric PON, a ʻo ka piʻi / lalo o ka port PON he 2.5G / 10G;XGS-PON mea symmetrical PON, a me ka up/downstream rate o ka PON awa he 10G/10G.

ʻO nā ʻenehana PON nui i kēia manawa ʻo GPON a me XG-PON, ʻo GPON a me XG-PON nā PON asymmetric.No ka mea he asymmetric maʻamau ka ʻikepili i luna / lalo o nā mea hoʻohana, e lawe ana i kekahi kūlanakauhale pae ma ke ʻano he laʻana, ʻo ka uplink traffic o OLT he 22% wale nō o ka downlink ma ka awelika, no laila ua kūlike nā ʻano loea o ka asymmetric PON i nā pono o nā mea hoʻohana.ʻOi aku ka mea nui, ʻoi aku ka haʻahaʻa o ka uplink rate o asymmetric PON, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka hoʻouna ʻana i nā ʻāpana e like me nā lasers i ka ONU, a ʻoi aku ka haʻahaʻa o ke kumukūʻai o nā lako.
ʻO ka noho pū ʻana o XGS-PON me XG-PON a me GPON, ʻo XGS-PON kahi ʻenehana loea o GPON a me XG-PON, e kākoʻo ana i ke komo ʻana o GPON, XG-PON a me XGS-PON.
ʻenehana XGSPON
Hoʻohana ka downlink o XGS-PON i ke ʻano hoʻolaha, a hoʻohana ka uplink i ke ʻano TDMA.
Ma muli o ka like o ka hawewe downlink a me ka downlink rate o XGS-PON a me XG-PON, ʻaʻole ʻokoʻa ka downlink o XGS-PON ma waena o XGS-PON ONU a me XG-PON ONU, hoʻolaha ka mea hoʻokaʻawale i ka hōʻailona optical downstream i kēlā me kēia XG (S) -PON (XG-PON a me XGS-PON) ONU ma ka loulou ODN like, a koho kēlā me kēia ONU e loaʻa i kāna hōʻailona ponoʻī a hoʻolei i nā hōʻailona ʻē aʻe.
ʻO ka upstream o ka XGS-PON e hoʻouna i nāʻikepili e like me ka manawa manawa, aʻo ka ONU e hoʻouna i nāʻikepili i loko o ka manawa manawa i laikiniʻia e OLT.Hoʻokumu ʻia ka OLT i nā koi kaʻa o nā ONU like ʻole a me ke ʻano o ONU.Hoʻokaʻawale ikaika i nā kau manawa.ʻO 2.5Gbps ka nui o ka lawe ʻana i ka ʻikepili i ka manawa i hoʻokaʻawale ʻia i ka XG-PON ONU, a me 10Gbps i ka manawa manawa i hoʻokaʻawale ʻia i ka XGS-PON ONU.
No ka mea ʻokoʻa ka lōʻihi o luna/lalo mai GPON, hoʻohana ʻo XGS-PON i ka papahana Combo e kaʻana like i ka ODN me GPON.
XGS-PON's Combo optical module hoʻohui GPON optical module, XGS-PON optical module a me WDM combiner.
Ma ke ala o ka uplink, ma hope o ke komo ʻana o ka hōʻailona optical i ke awa XGS-PON Combo, WDM kānana i ka hōʻailona GPON a me ka hōʻailona XGS-PON e like me ka lōʻihi o ka nalu, a laila hoʻouna i ka hōʻailona i nā ala like ʻole.
Ma ke ala i lalo, ua hoʻonui ʻia ka hōʻailona mai ka GPON & XGS-PON channel ma o WDM, a ʻo ka hōʻailona hui ʻia i lalo i ka ONU ma o ka ODN, a no ka ʻokoʻa ʻana o nā nalu, koho nā ʻano ONU i ko lākou mau nalu i makemake ʻia ma o loko. nā kānana e loaʻa nā hōʻailona.
No ka mea, kākoʻo maoli ʻo XGS-PON i ka noho pū ʻana me XG-PON, ʻo ka Combo solution o XGS-PON ke kākoʻo i ka hui ʻana o GPON, XG-PON a me XGS-PON, a ua kapa ʻia ʻo Combo optical module o XGS-PON he ʻekolu-mode. Combo optical module (ʻoiai ka Combo optical module o XG-PON i kapa ʻia he ʻelua-mode Combo optical module no ka mea e kākoʻo ana i ka hui ʻana o GPON a me XG-PON).
No ka mālama ʻana iā ʻoe ma mua o nā mea ʻē aʻe, manaʻo mākou e hoʻohana i kā mākou XGXPON OLT LM808XGS, ʻike hou aku e ʻoluʻolu e nānā i kā mākou pūnaewele:www.limeetech.com
