ʻO GLB3500M-3 Terr TV a me hoʻokahi LNB ākea ākea ma luna o ka fiber
Hōʻike huahana
ʻO GLB3500M-3 kahi modular CWDM broadband RF fiber link, e hoʻouna ana i ʻelua 290MHz ~ 2350MHz Satellite RF (kākoʻo iā UK 290MHz ~ 2340MHz a i ʻole ʻEulopa 300MHz ~ 2350MHz) a me hoʻokahi 45MHz ~ 806MHz Terrestrial TV RF ma luna o hoʻokahi SM fiber i nā mea kākau inoa lehulehu. Aia ka wideband RF ma 1530nm a i ʻole 1550nm, aia ka terrestrial TV RF ma 1570nm. Loaʻa ka fiber optic CWDM mux a i ʻole demux device ma ka mea hoʻouna optical a i ʻole e loaʻa i ka ʻike ʻana i hoʻokahi hoʻouna fiber.
Ua kaulana ʻo SMATV (Satellite Master Antenna TV) e hāʻawi i ka TV satelite a me ka TV terrestrial i nā mea kūʻai aku e noho ana ma nā hale a i ʻole ke kaiāulu. Hiki i ka SMATV kuʻuna ke puʻunaue i ka ʻike antenna master ma o ka multiswitch i nā mea hoʻokipa ukali ma luna o ke kaula coaxial. Ma muli o ka pohō kiʻekiʻe ma ke alapine satellite kiʻekiʻe, ʻoi aku ka liʻiliʻi o ka mamao o ke kelepona SMATV ma mua o 150 mika me ka mea hoʻonui pūnaewele IF. ʻAʻole like me ka ʻōnaehana Quattro LNB SMATV maʻamau, ʻo ka ʻōnaehana LNB SMATV ākea ka hapalua o nā mea hoʻohui RF a me nā helu kelepona hapalua, e mālama ai i ke kumukūʻai o ka lawe ʻana. Ma hope o ka fiber i ka hale, pono e hana ka wideband SMATV optical receiver me dCSS multiswitch e loaʻa i hoʻokahi hua RF me 32 mau mea hoʻohana ikaika, kahi o kēlā me kēia mea hoʻohana no hoʻokahi mea kākau inoa STB satellite uncable. ʻO kēia fiber hoʻokahi i ka hale a me hoʻokahi kaula coaxial i nā mea hoʻohana lehulehu i loko o ka hale e maʻalahi ka hoʻonohonoho ʻana a me ka mālama ʻana.
ʻO ka loulou fiber GLB3500M-3 me GLB3500M-3T ka mea hoʻolele uila a me ka mea hoʻokipa optical GLB3500M-3R. Me ka CWDM lasers/photodiode a me ka leo haʻahaʻa RF loaʻa ka mana kaapuni, hoʻokahi GLB3500M-3T hiki ke hāʻawi i ka RF kiʻekiʻe i ka 32pcs GLB3500M-3R optic loaʻa pololei.
Nā hiʻohiʻona ʻē aʻe:
• Hale alumini paʻa.
• 3 kūʻokoʻa broadband RF ma luna o hoʻokahi SM fiber transmission.
• ʻO kēlā me kēia RF bandwidth: wideband LNB 290 ~ 2350MHz a i ʻole 45 ~ 806MHz.
• Kiekie Linearity Photodiode.
• ka leo haʻahaʻa RF Gain Control circuit.
