4 Sats ma luna o GPON
ʻO Nilesat, Eutelsat 8W, Badr 4/5/6/7 & Es'hail 2, Hot Bird 13E nā satelite kaulana i ka waena hikina.Makemake nā kānaka e nānā iā lākou.He hana paʻakikī na ka ʻohana hoʻokahi e hoʻokomo i ʻehā mau kīʻaha ukali e lawelawe ana i hoʻokahi mea hoʻokipa ukali.He hana paʻakikī na ka poʻe kākau inoa e noho ana ma ka hale hoʻokahi e kaʻana like i nā kīʻaha satellite ʻehā ma luna o kahi pūʻulu o nā uwea coaxial.ʻO ka pūnaewele ka mea nui i koi ʻia ma kēia honua.Inā loaʻa iā GPON fiber i kēlā me kēia mea kākau inoa, ʻo Greatway Technology e maʻalahi kēia hana ma ke kumukūʻai kūpono.Hāʻawi kēia manaʻo i ka hoʻonā o 4 satellite i koho ʻia i ka FTA kaulana a i ʻole nā mea i hoʻopili ʻia FTTH ma kahi o 2800 GPON ONU mea kākau.
Hoʻoponopono ʻia nā Satellite Transponders e dCSS LNB ma ke ʻano static
Loaʻa i kēlā me kēia satellite ma kahi o 10~96 transponders.20% mea kaulana i ka 80% mea kākau.No ka mālama ʻana i kēlā me kēia kumukūʻai home FTTH, koho wale mākou i 32 transponders kaulana (32 User Bands) mai kēlā me kēia satellite i nā hale GPON āpau.No ka hana ʻana i kēia, pono mākou i 4pcs dCSS static LNB me ka 32UB i koho ʻia o kēlā me kēia satellite.(Manaʻo mākou e hoʻohana i ka Inverto dCSS LNB a me SatPal a i ʻole nā huahana like. Hiki i ke ala nui ke hāʻawi i ka dCSS LNB me ka hoʻopuka static 32UB paʻa inā ʻike mākou i kāu inoa satellite a me 32 transponders makemake ʻia ma Horizontal a Vertical paha).
Hoʻololi hōʻailona DTT
Hāʻawi ʻia ka DTT e kekahi mau mea hana ma ke kūlanakauhale a hiki i nā hale kiaʻi hoʻouna DTT ke kū ma nā wahi like ʻole o ke kūlanakauhale.He ikaika paha ka hōʻailona DTT e pili ana i ka hale kiaʻi DTT e hoʻokomo pololei i ka hoʻonohonoho TV.No ka pale ʻana i ka hoʻopili alapine like, pono ia e hoʻohuli i nā alapine DTT a pau ma mua o ka hoʻokomo ʻana o ka transmitter Terr TV.Ma kēia papahana, aia nā mea lawe RF Terrestrial 3: VHF7 a me UHF32, UHF36.Manaʻo mākou e hoʻohana i hoʻokahi GTC250 terrestrial TV frequency converter no ka loaʻa ʻana o nā alapine TV Terrestrial hou: VHF8, a me UHF33 a me UFH31 (Ma muli o nā hiʻohiʻona PAL-B/G a me DTT, paipai mākou iā VHF i VHF a me UHF i UHF hoʻololi. ).Loaʻa iā GTC250 ʻehā mau mea hoʻokomo VHF/UHF a hoʻokahi a hiki i ka 32ch DTT RF kiʻekiʻe loa.Hiki i ka 1pcs GTC250 ke hoʻopuka i ka 3ch DTT RF kiʻekiʻe maʻemaʻe (kēlā me kēia ma 85dBuV RF pae) i ka transmitter optical, kānana a pale ʻana i nā hōʻailona kelepona 4G a me 5G.
Mea hoʻolele ʻopika
1pcs GLB3500M-4TD DWDM optical transmitter loaʻa iā 4x32UB satellite inputs a me hoʻokahi DTC250 terrestrial RF hoʻokomo, hoʻololi iā lākou āpau ma luna o 1550nm DWDM SM fiber.
Pono e hoʻokomo i ka transmitter optical GLB3500M-4TD i loko.Pono ka uwea coaxial RG6 i kēlā me kēia dCSS LNB lōʻihi ma lalo o 50 mika.
Māhele Optical
No ka mea ua hui pū ʻia nā mea kākau inoa 2800 GPON e 1x16 splitter, aia ma kahi o 175 mau pūʻulu.
Loaʻa iā GLB3500M-4TD ma kahi o +9dBm ka mana puka, e ukali ʻia e 1pcs 1x4 PLC splitter mua.Ma waena o ka 4 splitter outputs, 3 splitter outputs e pili ana me 3pcs mana kiʻekiʻe GWA3500-34-64W.1 mea hoʻokaʻawale ma ke ʻano he awa kū.
Mea Hoʻonui Optical
Loaʻa i kēlā me kēia GWA3500-34-64W hoʻokahi hoʻokomo optical 1550nm, 64 OLT inputs, a me 64 com ports, kahi i loaʻa i kēlā me kēia port com >+12dBm@1550nm.Hoʻopili ʻia kēlā me kēia port port me 1x16 PON splitter, e hāʻawi ana i ka TV noho a me GPON Ethernet.
Pono e hoʻokomo ʻia GWA3500-34-64W mea hoʻonui optical ma kahi o GPON OLT a i ʻole kokoke i ka hub uwea fiber.3pcs GWA3500-34-64W optical amplifiers he 192 puka puka, ma waho aʻe o nā awa pili 175, nā awa i hoʻohana ʻole ʻia e like me nā awa kū.
Pono ka ʻōnaehana GPON mua e hoʻokomo i ka splitter 1x16.Ua helu mākou iā lākou ma ka BOM inā makemake ʻoe i ka splitter 1x16.
Optical Loaʻa a me GPON ONU
Ma kēlā me kēia GPON ONU, manaʻo mākou e hoʻohana i kahi mea hoʻopili SC / UPC a me 1 mika duplex SC / UPC i ka LC / UPC jumper, kahi e hoʻohuli ai ka fiber 1 i ka fiber SC / UPC e komo mai ana i LC / UPC i GLB3500M-4RH4-K optical LNB a me ka nā mea ʻē aʻe e hoʻohuli i ka loop out GPON hōʻailona i SC/UPC i ka GPON ONU.
Loaʻa iā GLB3500M-4RH4-K ʻehā mau awa RF, ʻo kēlā me kēia awa RF hāʻawi i nā ʻike satellite 4x32UB a me ka TV terrestrial.Inā ʻoi aku ka nui o nā decoders satellite ma mua o 4 ma kēlā me kēia wahi GPON ONU, hiki ke hoʻopili ʻia kēlā me kēia awa RF o GLB3500M-4RH4-K e hoʻokahi 4-ala a i ʻole 8-ʻaoʻao satellite splitter e kākoʻo i 16 a i ʻole 32 mau mea hoʻokipa ukali, kahi i loaʻa ai i ka satellite splitter. hoʻokahi awa RF hele DC wale nō.ʻO ka mea hoʻokipa ukali e pili ana me ke awa hele DC e koho i ka 1 o nā satelite ʻehā, nā mea hoʻokipa ukali e hoʻopili ana ma ke awa ʻole DC e nānā i nā mea i koho ʻia 32UB satellite.
Lawe Satellite
Hiki i ka mea hoʻokipa ukali maʻamau e kākoʻo ana i ka huli ʻana i nā ʻike satellite lehulehu ke nānā i nā mea āpau FTA a me nā mea i hoʻopili ʻia me ka kāleka CA.ʻAʻohe pono hana uncable ma ka mea lawe ukali.
ʻOlu pulu
Ma muli o ka EYDFA kiʻekiʻe kiʻekiʻe, hiki iā mākou ke hoʻohana i ka mea hoʻohui LC/UPC ma kahi o ka mea hoʻohui SC/UPC.Pono e loaʻa i kahi patchcord fiber lele e like me LC / UPC i SC / UPC a i ʻole LC / APC i SC / APC.
No ka ʻike piha, e ʻoluʻolu e nānā i ka faila pdf a i ʻole e kelepona iā Greatway Technology.
