Tayo wanaagsan Fwxg-890sg Xgs-Pon Ont (Unuga Qoyska Keliya)
Iyadoo halkudheggan maskaxda lagu hayo, waxaan noqonay mid ka mid ah kuwa ugu macquulsan ee ugu casrisan tignoolajiyada, kharash-ku-dhaqmaadka badan, iyo soo-saareyaasha qiimaha-ku-tartama ee tayada Wanaagsan Fwxg-890sg Xgs-Pon Ont (Unuga Qoyska Keliya), Shirkaddeennu waxay ahayd u go'ay "macmiilka marka hore" oo ay ka go'an tahay inay ka caawiyaan dukaameeysatada inay ballaariyaan ganacsigooda yar, si ay u noqdaan Madaxa Weyn!
Anigoo maskaxda ku hayna halku-dhiggan, waxaan noqonay mid ka mid ah kuwa ugu macquulsan ee ugu casrisan tignoolajiyada, kharash-ku-ool ah, iyo soo-saareyaasha ugu tartanta qiimaha badan.Shiinaha ONU iyo Epon ONUWaxaan had iyo jeer u hoggaansanahay in aan raacno daacadnimada, faa'iidada wadaagga ah, horumarka guud, ka dib sannado badan oo horumarineed iyo dadaalka hagar la'aanta ah ee dhammaan shaqaalaha, hadda waxay leedahay nidaamka dhoofinta qumman, xalalka saadka kala duwan, la kulanka macaamiisha macaamiisha, gaadiidka hawada, adeegga caalamiga ah iyo adeegyada saadka. . U sharax madal hal-joojin ah ee macaamiisheena!
Sharaxaada Alaabta
GLB3500M waa modular 45 ~ 2600MHz RF oo ka sarreeya isku xirka fiber-ka, gudbinta kanaalada TV-ga dhulka iyo hal L-Band RF oo ka sarreeya hal fiber.
Satellite-ka tooska ah ee baahinta tooska ah (DBS) iyo Tooska u ah Guriga (DTH) waa habka ugu caansan ee looga raaxaysto TV-ga satalaytka adduunka oo dhan. Si taas loo sameeyo, anteenada dayax-gacmeedka, fiilada coaxial, kala qaybisa ama beddelaha badan iyo qaataha dayax-gacmeedku waa lagama maarmaan. Si kastaba ha ahaatee, rakibidda anteenada dayax-gacmeedka ayaa laga yaabaa inay ku adkaato macaamiisha ku nool guryaha. SMTV (satellite mater antenna TV) waa xal fiican oo dadka ku nool dhismaha ama beesha ay wadaagaan hal saxan oo satelayt ah iyo anteenada TV-ga dhulka. Xadhkaha fiber-ka, SMTV RF signal waxa la geyn karaa 30Km ka fog ama waxa loo qaybin karaa 32 guri oo toos ah, 320 ama 3200 ama 32000 guri oo la sii marinayo GWA3530 fibre optic amplifier.
GLB3500M wuxuu ka kooban yahay GLB3500MT moduleka gudbiyaha iyo GLB3500MR moduleka qaataha. Qalabka gudbiyaha ee GLB3500MT wuxuu leeyahay hal ama laba dekedood RF ah halka GLB3500MR uu leeyahay hal deked wax soo saar RF ah. Iyada oo xariiqda sare ee 1550nm aan qaboojinayn DFB laser, photodiode iyo qaylada hoose ee RF kontoroolka kontoroolka, GLB3500MT waxay keeni kartaa kanaalada TV-ga Terrestrial TV oo tayo sare leh iyo dayax gacmeedka RF ee fiber-ka macaamiisha si toos ah ama kumanaan macaamiisha FTTH ah iyada oo loo sii marayo EDFA. Iyada oo leh 1310nm/1490nm/1550nm WDM doorashada, GLB3500M waxa ay gelin kartaa L-Band+TV RF GPON/GEPON. Nooca modular ka sokow, GLB3500M wuxuu lahaan karaa 19"1RU nooca marka la codsado. Fiber-ka nooca guriyeynta balaastikada ah ee GLB3500MR waa GFH2000 indhaha LNB, halkaasoo macaamiisha FTTH ay kaliya u baahan yihiin hal fiber oo ka soo saara calaamadaha satalaytka qolal badan oo qoyska ah.
Sifooyin kale:
• Guryaha dhinta aluminium ee is haysta.
• Gelida RF kaliya ee la isku daray oo leh bandwidth:45 ~ 2600MHz ama.
Laba qalab oo RF ah oo kala soocan, oo ay ku jiraan:
-Hal ka mid ah TV ga Terrestrial, bandwidth: 174 -806 MHz.
-Hal gelis LNB RF, bandwidth: 950MHz ~ 2150MHz (13V ama 18V DC doorasho LNB haddii la codsado).
Hal deked wax soo saar RF ah.
• Khadka sare 1550nm DFB Laser iyo Photodiode aan qaboojin.
• Sawaxanka hooseeya ee RF Gain Control circuit.Iyadoo halku-dheggan maskaxda lagu hayo, waxaan u nimid inaan noqonno mid ka mid ah kuwa ugu macquulsan ee tignoolajiyada ugu hal-abuursan, kharash-ku-ool ah, iyo soo-saareyaasha ugu tartanta qiimaha Fwxg-890sg Xgs-Pon Ont ( Single Unugga Qoyska), Shirkaddayadu waxay u heellan tahay "macmiilka marka hore" oo ay ka go'an tahay inay ka caawiso dukaameeysatada inay ballaariyaan ganacsigooda yar, si ay u noqdaan Maamulaha Weyn!
