GLB3500M-4D Lisathelaete tse 'ne tsa DWDM FTTH tse nang le GPON
Tlhaloso ea Sehlahisoa
GLB3500M-4D ke sehokelo sa modular sa DWDM Broadband RF fiber, se fetisetsang 950 ~ 2150MHz Satellite RF e le 'ngoe le 174~806MHz Terrestrial TV RF holim'a fiber e le' ngoe ea SM ho ba ngolisitseng ba bangata ba FTTH. Li-RF tsa sathelaete tse 'ne e ka ba VL/VH/HL/HH ho tsoa ho Quattro LNB e le' ngoe kapa 32UB tse 'ne tse tsitsitseng ho tsoa ho li-satellite dCSS LNB tse nne.
Li-satellite tse 'nè li na le li-transponder tse ngata sathelaete e' ngoe le e 'ngoe. Ha e le hantle, ke 20% feela ea litaba tsa satellite e tsebahalang ho 80% ea ba ngolisitseng. Likahare tsohle ho tloha ho lisathelaete tse 'ne holim'a lithapo tsa coaxial ho isa ho lithapo tsa faeba ho ea lehaeng ka leng li bitsa chelete e ngata. Sistimi ea GLB3500M-4D e khetha li-transponder tse tsebahalang haholo ho bohle ba ngolisitseng. Li-transponder tse 32 tse tsoang satellite e 'ngoe le e 'ngoe li lokela ho kenyelletsa litaba tse hlahang ka ho fetisisa tsa sathelaete. Ka thekenoloji ea 4ch DWDM le matla a phahameng a 1550nm optical amplifier, GLB3500-4D e ka kenya li-satellite tsa 4 ka kakaretso ea 128 transponders ho GPON kapa tsamaiso ea XGPON leha e le efe. Ho dCSS LNB static mode, ba amohelang sathelaete e ka ba mokhoa o tloaelehileng oa ho shebella litaba tsohle tse 4 tse khethiloeng ka satellite.
Sehokelo sa fiber sa GLB3500M-4D se kenyelletsa GLB3500M-4TD DWDM transmitter optical le GLB3500M-4RD4 FTTH optical receiver. Moamoheli oa mahlo o na le likou tse 4 tsa RF, kou ka 'ngoe e ts'ehetsa ho shebella 32UB e kenang ea sathelaete efe kapa efe e kenang. Ka li-lasers/photodiode tsa DWDM le lerata le tlaase la taolo ea RF, e le 'ngoe ea GLB3500M-4TD e ka fana ka RF ea boleng bo phahameng ho ea ho 32 GLB3500M-4RD4 optic receivers ka ho toba kapa likete tse amohelang GLB3500M-4RD4 optic ka matla a phahameng a optical amplifier.
Likarolo tse ling:
• Compact aluminium housing e nang le heatsink e babatsehang le ho itšehla thajana ea RF.
• Quattro LNB e le 'ngoe (kapa li-dCSS LNB tse 'nè) le Terr TV holim'a phetiso e le 'ngoe ea SM fiber.
• Li-bandwidth tse 'nè tsa RF tsa sathelaete: 950MHz ho isa ho 2150MHz.
• Fetola 13V/18V DC ho Quattro LNB kapa dCSS LNB.
