GLB3500M-4D Afar Satellites DWDM FTTH oo wata GPON
Sharaxaada Alaabta
GLB3500M-4D waa isku xirka xargaha fibreerka ee DWDM ee RF, oo gudbiya afar 950 ~ 2150MHz Satellite RF iyo hal 174 ~ 806MHz Terrestrial TV RF oo ka sarreeya hal fiber SM macaamiisha FTTH badan.Afarta dayax-gacmeedka RF waxay noqon karaan VL/VH/HL/HH mid ka mid ah Quattro LNB ama afar 32UB oo taagan afar dayax-gacmeed dCSS LNBs.
Afar dayax-gacmeed ayaa ku leh dayax-gacmeedyo badan.Dhab ahaantii, kaliya 20% waxyaabaha ku jira dayax-gacmeedka ayaa caan ku ah 80% macaamiisha.Dhammaan waxa ku jira afar dayax-gacmeed oo kor u dhaafaya fiilada coaxial ilaa fiilada fiber ee guri kasta waa qaali.Nidaamka GLB3500M-4D ayaa dooranaya gudbiyeyaasha ugu caansan dhammaan macaamiisha.32 transponders ee dayax-gacmeed kasta waa in ay ku jiraan waxa ugu muuqda ee dayax-gacmeedka.Iyada oo la adeegsanayo tignoolajiyada 4ch DWDM iyo awood sare oo ah 1550nm optic amplifier, GLB3500-4D waxay gelin kartaa 4 satalayt oo wadarta 128 transponders ah nidaamka GPON ama XGPON.Qaabka taagan dCSS LNB, satalayt-ku-qaadayaasha waxay noqon karaan qaabka caadiga ah ee daawashada dhammaan 4-ta satelayt ee la doortay.
GLB3500M-4D isku xirka fiber waxaa ka mid ah GLB3500M-4TD DWDM gudbiyaha indhaha iyo GLB3500M-4RD4 FTTH soo dhaweynta indhaha.Soo dhaweynta indhaha waxay leedahay 4 dekedood oo RF ah, deked kastaa waxay taageertaa daawashada 32UB ee soo galaya dayax-gacmeed kasta.Iyada oo leysarka DWDM/photodiode iyo sanqadha hoose ee RF kontoroolka kontoroolka, hal GLB3500M-4TD waxay keeni kartaa RF tayo sare leh ilaa ugu badnaan 32 GLB3500M-4RD4 aqbaleyaasha indhaha si toos ah ama kumanyaal GLB3500M-4RD4 ah oo qaata qalabka indhaha iyadoo la adeegsanayo cod-weyneeye sare oo awood sare leh.
