GLB3500M-4D Eha Satellites DWDM FTTH me GPON
Hōʻike huahana
ʻO GLB3500M-4D kahi modular DWDM broadband RF fiber link, e hoʻouna ana i ʻehā 950 ~ 2150MHz Satellite RF a me hoʻokahi 174 ~ 806MHz Terrestrial TV RF ma luna o hoʻokahi fiber SM i nā mea kākau inoa FTTH lehulehu. Hiki i nā RF satellite ʻehā ke VL/VH/HL/HH mai hoʻokahi Quattro LNB a i ʻole ʻehā 32UB mau mai nā LNB dCSS satellite ʻehā.
ʻEhā mau ukali he nui nā transponder ma kēlā me kēia ukali. ʻO kaʻoiaʻiʻo, he 20% wale nō nā mea o ka satellite i kaulana i ka 80% mea kākau. ʻO nā mea a pau mai nā satelite ʻehā ma luna o ke kaula coaxial a hiki i ke kaula fiber i kēlā me kēia home he pipiʻi. Koho ka ʻōnaehana GLB3500M-4D i nā transponder kaulana loa i nā mea kākau inoa a pau. Pono nā transponder 32 mai kēlā me kēia ukali e komo i nā mea i hōʻike nui ʻia o ka satellite. Me ka ʻenehana 4ch DWDM a me ka mana kiʻekiʻe 1550nm optical amplifier, hiki iā GLB3500-4D ke hoʻokomo i nā satelite 4 me ka nui o nā transponders 128 i kekahi ʻōnaehana GPON a i ʻole XGPON. Ma ke ʻano static LNB dCSS, hiki i nā mea lawe ukali ke ʻano maʻamau e nānā ana i nā mea āpau i koho ʻia.
ʻO ka loulou fiber GLB3500M-4D me ka GLB3500M-4TD DWDM mea hoʻolele uila a me GLB3500M-4RD4 FTTH mea hoʻokipa. ʻO ka mea hoʻokipa optical he 4 mau awa RF, e kākoʻo ana kēlā me kēia awa i ka nānā ʻana i ka 32UB e komo mai ana o nā satellite e hiki mai ana. Me ka DWDM lasers/photodiode a me ka leo haʻahaʻa RF loaʻa ka mana kaapuni, hoʻokahi GLB3500M-4TD hiki ke hāʻawi i ka RF kiʻekiʻe kiʻekiʻe i ka 32 GLB3500M-4RD4 optic loaʻa pololei a i ʻole mau tausani o nā mea hoʻokipa optic GLB3500M-4RD4 ma o ka mana kiʻekiʻe optical amplifier.
Nā hiʻohiʻona ʻē aʻe:
• Hale alumini paʻa me ka heatsink maikaʻi loa a me ka hoʻokaʻawale RF.
• Hoʻokahi Quattro LNB (a i ʻole ʻehā dCSS LNB) a me Terr TV ma luna o hoʻokahi hoʻouna fiber SM.
• Eha ukali RF bandwidth: 950MHz i 2150MHz.
• Hoʻohuli i ka 13V/18V DC i Quattro LNB a i ʻole dCSS LNB.
• 'O ka bandwidth TV Terrestrial: 174~806MHz.
• 1550nm C-band DWDM nalu nalu ma ka laulā o EDFA a i ʻole EYDFA.
• AGC ma ka mea hoʻolele a me ka mea hoʻokipa.
• Kiekie Linearity Photodiode.
• Hoʻokaʻawale RF maikaʻi loa.
• ka leo haʻahaʻa RF Gain Control circuit.
• 19" 1RU Hale koho.
