1.Introduction to Triple play ONU
ʻO 1.1Triple pāʻani ONU kahi huahana mea kūʻai aku o ka ʻike loea passive i hoʻokumu ʻia e kā mākou hui no ka mākeke komo ākea e pili ana i ka ʻenehana GPON/EPON.Hiki i ka huahana ke hoʻokō i nā pono o ka FTTH / FTTR / FTTx fiber-to-the-home a me nā mea hoʻohana fiber-to-the-room, hāʻawi i nā mea hoʻohana i ke ala ākea kiʻekiʻe ma muli o GPON / EPON, a ʻike i ka ʻikepili i hoʻohui ʻia, wikiō a me ka leo. lawelawe.
1.2Ma muli o ka ʻenehana ITU-T G.984 / China Telecom CTC3.0, ka hanauna hou loa o ka broadband passive optical network integrated access standards, ʻo ka Triple play ONU he nui nā pono e like me ka bandwidth kiʻekiʻe, ka hana kiʻekiʻe, ka uhi nui, nā mea hoʻohana waiwai. , a me nā mea ʻē aʻe, a he ʻenehana kūpono no nā mea hoʻokele / hōkele / hale e ʻike i ka broadband a me ka hoʻololi piha ʻana o nā lawelawe ʻoihana ʻike.
Hāʻawi ʻo 1.3Triple play ONU i 1 gigabit a me 100 megabit adaptive port port, 1 leo leo, 1 CATV interface, a me 802.11 b/g/n maʻamau Wi-Fi.Ua ʻike ka hāmeʻa i ka pilina a me ka interoperability me ka GPON / EPON local terminal equipment (OLT) o nā mea hana kamaʻilio koʻikoʻi o ka ʻoihana (Huawei / ZTE / Fiberhome / HDV Fiber) e hana i kahi ʻōnaehana gigabit e hoʻokō i nā koi komo FTTH / FTTx o ka leo. a me nā lawelawe ʻikepili.I ka manawa like, hiki i kāna hana WIFI ke hāʻawi i nā mea hoʻohana i nā ʻano ʻano o nā kikowaena kelepona i loko ma o nā koi komo WIFI.
1.4Triple pāʻani ONU i hoʻohui ʻia i ka hana uea ʻole, piha i ka laina me ka 802.11 b/g/n maʻamau maʻamau protocol, ʻelua ʻaoʻao kiʻekiʻe kiʻekiʻe kiʻekiʻe omnidirectional antenna, hoʻokahi-frequency uea hoʻolele uila a hiki i ka 300Mbps, pālua kaʻina uila uila a hiki i 1200Mbps , me ke komo ikaika, ka uhi ākea a me nā hiʻohiʻona ʻē aʻe, e hāʻawi i nā mea hoʻohana me ka hōʻoia ʻana i ka hoʻouna ʻikepili ʻoi aku ka maikaʻi.

2.Hotel hoʻohui uea noi o Triple pāʻani ONU
ʻO ka ʻenehana hoʻokaʻawale ʻokoʻa WDM hawewe nalu o ka Triple play ONU he fiber hoʻokahi ʻekolu nalu: hoʻokahi fiber optical uniformly lawe i nā lawelawe IP a me nā lawelawe CATV, a hāʻawi i nā lawelawe loulou e like me nā lawelawe TV, nā lawelawe pūnaewele, nā lawelawe kelepona, a me nā lawelawe laka puka akamai no kēlā me kēia lumi.
Pono:
2.1 Hoʻokahi fiber optical e lawe i nā lawelawe a pau, ua maʻalahi ka wili, ua hoʻemi ʻia ke kumukūʻai wili, ua hoʻokaʻawale ʻia ka ʻikepili a me nā lawelawe CATV e nā hawewe like ʻole, hoʻohana ka lawelawe data i ka hawewe nalu 1310nm i luna, hoʻohana ka downlink i ka hawewe nalu 1490nm, a hoʻohana ka lawelawe CATV i 1550nm lōʻihi nalu.
2.2 Kākoʻo ʻekolu pāʻani ONU i ka pūnaewele maʻalahi GPON/EPON OLT, me ka hilinaʻi kiʻekiʻe, ke kumu kūʻai haʻahaʻa, ka hoʻolālā pūnaewele pālahalaha, ke komo like ʻana o nā hopena āpau, a me ka pūnaewele maʻalahi.ʻO ka mīkini spectroscopic passive, ʻaʻohe o ka mālama ʻana i ka mana, ʻaʻole maʻalahi e hoʻopilikia ʻia e ke kaiapuni o waho, haʻahaʻa haʻahaʻa haʻahaʻa.
