Introduction: Ua māhele ʻia ʻo ONU (Optical Network Unit) i loko o ka ʻenehana optical optical a me ka passive optical network unit, ʻo ONU ka mea hoʻohana i ka mea hoʻohana ma ka pūnaewele optical, kau ʻia ma ka hopena mea hoʻohana, hoʻohana ʻia me OLT e hoʻokō i ka Ethernet Layer 2, Layer 3 hana. , e hoʻolako i nā mea hoʻohana i nā lawelawe leo, ʻikepili a me multimedia.

Ke kukui uila: ʻOmaomao Paʻa: ʻAʻole mana;ʻŌmaʻomaʻo On: Power on
Māmā PON: ʻOmaomao ma: lōʻihi ma ka hōʻike ʻana ua hala ka papa i ka hoʻāʻo ponoʻī a ke hana maʻamau nā mea hana
LOS Māmā: Paʻa: Maʻamau
Hoʻoponopono i ka hewa o ka mea hoʻohana:
ʻO ka hapa nui o nā hewa he mau hewa laina fiber optical a me nā hewa lako ONU.ʻO ka mua, e nānā inā he maʻamau ka hōʻailona panel.I ka hihia o ka laina laina fiber optical, e ʻike i ke kūlana o ke kukui PON: inā he ʻōmaʻomaʻo ke kukui PON, hōʻike ia he mea maʻamau ka laina fiber optical, a inā pio ke kukui PON, hōʻike ia ua hemo ka laina fiber optical.
E ho'āʻo i ka laina fiber optical me ka mīkini mana mana.ʻO ka laulā kūpono o ka mana optical: 1490nm range: - 8dB i - 28dB.Inā ʻoi aku ia ma mua o ka laulā, pili ia i ka maikaʻi o ka hana maʻamau o ONU a pili ka ʻike pūnaewele o ka mea hoʻohana.E nānā i ka laina fiber optical pae kiʻekiʻe a e hoʻāʻo i ka pulupulu huelo o ka mea hoʻokaʻawale e pili ana i ka uwea ʻōpika o ka mea hoʻohana hewa ma ka pahu uwea opi.
ʻO ka attenuation o ka 2-way optical splitter ʻo -3db
ʻO ka attenuation o ka 4-way optical splitter ʻo -6db
ʻO ka attenuation o ka 8-way optical splitter ʻo -9db
ʻO ka attenuation o ka 16-way optical splitter he -12db
ʻO ka attenuation o ka 32-way optical splitter he -15db
ʻO ka attenuation o ka 64-way optical splitter ʻo -18db
1. Inā kūpono ka mana optical o ka puaʻa splitter, e ʻoluʻolu e hoʻololi i ka fiber core ma waena o ka pahu hoʻoili kelepona optical a me ka hale.ʻO ka maʻamau, waiho mākou ma kahi o ʻelua mau kiko fiber i loko o ka hale, a laila hoʻāʻo i ka hopena ma hope o ke pani ʻana.Inā ʻo ia ka huelo mai ka splitter a ʻaʻole kūpono kona mana optical o ka fiber, e ʻoluʻolu e hoʻololi i ka puaʻa ʻokoʻa, a hoʻohana i kahi mika mana optical e hoʻāʻo ai i kahi mea kūpono e hoʻopili i ka pigtail hale.
2. Inā hewa ka laina fiber optical: e wehe mua i ka puaʻa ma ka ONU e ho'āʻo ai i ka mana optical, ināʻaʻohe kukui a iʻole ka mana kūponoʻole, eʻoluʻolu e hele i ka flange o ka pahu hoʻoili kelepona optical e huli i kahi o nā 1-32 pigtails o ka optical splitter e pili ana i ka ONU Inā kūponoʻole ka puaʻa, hiki iāʻoe ke pani i kekahi o nā 1-32 idle pigtails.E hoʻomanaʻo: ʻaʻole hiki ke huki ʻia ka fiber nui o ka splitter optical, e hoʻopilikia i nā ONU āpau.

Kukui mana: Hoʻa mau ke kukui ʻōmaʻomaʻo: Hoʻa ka mana;Paʻa ke kukui ʻōmaʻomaʻo: pio ka mana
LOS Light: OFF: ʻO ka mana optical i loaʻa o ke awa PON he mea maʻamau;ʻAʻa mau ke kukui ʻōmaʻomaʻo: Ua ʻike ʻia ka mea hana a hoʻopaʻa inoa ʻia;ʻO ke kukui ʻōmaʻomaʻo: ʻAʻohe ʻikepili o ka hāmeʻa;Blink: ʻAʻohe kukui o ke awa PON a i ʻole ka mana o ka optical ma mua o ka ʻike ʻike.
ʻO LAN1, LAN2, LAN3 a me LAN4 he 4RJ45 Port
ʻO FXS1 ka Port Leo
Paʻa pilikia: ʻO ka mea mua, e nānā inā holo maʻamau ka mea ONU (inā maʻamau ke kukui hōʻailona ma ka papa hana), a laila e nānā i nā kumu ʻē aʻe ma hope o ka holo maʻamau o ka hāmeʻa.Ua like ke kaʻina hana me ka mea i luna.
No ka ʻoi aku ka naʻauao ONU / pahu ONU / kamaʻilio ONU / optical fiber ONU, hiki iā ʻoe ke hoʻopili pololei iā HDV Phoelectron Technology LTD no nā kikoʻī hou aku.Loaʻa i kā mākou hui nā huahana kamaʻilio o OLT, Media Converter, Switch a me SFP.Welina mai e kūkākūkā.
Mai kāu kamaʻilio akamai ONU&SFP mea hana.
