GLB3500M-4D Satellite anọ DWDM FTTH nwere GPON
Nkọwa ngwaahịa
GLB3500M-4D bụ modul DWDM brọdband RF njikọ eriri, na-ebufe anọ 950 ~ 2150MHz Satellite RF na otu 174 ~ 806MHz Terrestrial TV RF karịa otu SM fiber na ọtụtụ ndị debanyere aha FTTH. Satịlaịtị RF anọ nwere ike ịbụ VL/VH/HL/HH site na otu Quattro LNB ma ọ bụ anọ static 32UB sitere na dCSS LNB satịlaịtị anọ.
Satellite anọ nwere ọtụtụ transponders na satịlaịtị ọ bụla. N'ezie, naanị 20% ọdịnaya nke satịlaịtị na-ewu ewu na 80% ndị debanyere aha. Ihe niile sitere na satịlaịtị anọ n'elu eriri coaxial gaa na eriri eriri na ụlọ ọ bụla dị oke ọnụ. Sistemu GLB3500M-4D na-ahọrọ ndị ntụgharị kacha ewu ewu na ndị debanyere aha niile. 32 transponders sitere na satịlaịtị ọ bụla kwesịrị ịgụnye ọdịnaya kachasị egosipụta na satịlaịtị. Site na teknụzụ 4ch DWDM na ike dị elu 1550nm optical amplifier, GLB3500-4D nwere ike itinye satịlaịtị 4 na ngụkọta 128 transponders n'ime usoro GPON ma ọ bụ XGPON ọ bụla. N'ọnọdụ dCSS LNB static, ndị na-anata satịlaịtị nwere ike ịbụ ọnọdụ mgbe niile na-ekiri ọdịnaya satịlaịtị anọ ahọpụtara.
GLB3500M-4D eriri njikọ gụnyere GLB3500M-4TD DWDM nnyefe anya na GLB3500M-4RD4 FTTH ngwa anya nnata. Ihe nnata anya nwere ọdụ ụgbọ mmiri 4 RF, ọdụ ụgbọ mmiri ọ bụla na-akwado ikiri 32UB na-abata nke satịlaịtị ọ bụla na-abata. Na DWDM lasers/photodiode na obere mkpọtụ RF nweta akara sekit, otu GLB3500M-4TD nwere ike na-ebuga RF dị elu na kacha 32 GLB3500M-4RD4 optic receivers ozugbo ma ọ bụ puku kwuru GLB3500M-4RD4 optic receivers site na nnukwu ike ngwa anya amplifier.
Atụmatụ ndị ọzọ:
• Kọmpat ụlọ aluminom nwere ezigbo heatsink na ikewapụ RF.
• Otu Quattro LNB (ma ọ bụ dCSS LNB anọ) na Terr TV karịrị otu nnyefe eriri SM.
• bandwidth RF satịlaịtị anọ: 950MHz ruo 2150MHz.
• tụgharịa 13V/18V DC ka Quattro LNB ma ọ bụ dCSS LNB.
• bandwidth TV nke ụwa: 174 ~ 806MHz.
• 1550nm C-band DWDM wavelengths na nso nke EDFA ma ọ bụ EYDFA.
• AGC na transmitter anya na nnata.
• High Linearity Photodiode.
• Mmasị RF dị mma.
• Obere mkpọtụ sekit njikwa RF Gain.
• 19 "1RU Ụlọ Nhọrọ.
