GWT3500 1550nm CATV nnyefe
Nkọwa ngwaahịa
GWT3500 bụ onye na-ebugharị 1550nm DFB ozugbo maka TV analog, TV dijitalụ na CMTS na-egosi nkesa eriri eriri mpaghara yana mgbama QAM TV nnyefe eriri ogologo. Onye na-ebugharị na-eji laser DFB linearity dị elu, RF ike dijitalụ akpaka usoro usoro, yana RF pre-distortion sekit nke Greatway Technology mepụtara. Microprocessor arụnyere n'ime na-enyocha ọnọdụ onye na-ebufe na-arụ ọrụ ma na-eme ka arụmọrụ dị mma na-akpaghị aka. GWT3500 dị mma maka nkesa fiber analog TV n'ime 20Km na QAM TV mgbama ogologo nnyefe n'ime 100km.
E webatara eriri ka ọ na-ebunye CATV RF na 1990s n'ihi nkwụsị ya dị ala yana ihe fọrọ nke nta ka ọ bụrụ bandwidth na-akparaghị ókè. RF ka eriri ntụgharị bụ akụrụngwa kachasị mkpa. Site na ụda mkpọtụ dị ala na microprocessor, enwere ike ịhazi ike RF zuru ezu na laser nke ọma, hụ na index modulation kachasị mma (OMI). Laser DFB jụrụ oyi na onye na-ebufe na-eme ka ogologo ogologo anya anya DWDM kwụsiri ike maka mgbasa ozi ma ọ bụ tinye ọrụ mmekọrịta dị warara. Ka ọ dị ugbu a, laser DFB jụrụ oyi nwere laser RIN ka mma (mkpọtụ ike) yana ike mmepụta laser kwụsiri ike. Ortel-Emcore elu linearity jụrụ DFB laser na Greatway imewe ka egosipụtara na ọ bụ ngwakọta na-aga nke ọma. Ndị ahịa nọ na North America, South America na China ejirila GWT3500 mgbasa ozi anya n'ọtụtụ ebe yana arụmọrụ dị oke mma yana ntụkwasị obi gosipụtara nke ọma.
Ya na Greatway high power optical amplifier, GWT3500 transmitter nwere ike ibuga eriri ihe ngosi TV dị elu na ụlọ ma ọ bụ eriri n'ụlọ.
Atụmatụ ndị ọzọ:
• Obere mkpọtụ elu linearity Ortel-Emcore jụrụ DWDM DFB laser.
• GaAs ma ọ bụ teknụzụ GaN ruru 1218MHz.
• Nkà na ụzụ tupu ihe mgbagwoju anya na-eme ka CTB, CSO na C/N dịkwuo mma.
• Microprocessor arụnyere n'ime ya na-enyocha ike mmepụta laser na okpomọkụ.
• Kwesịrị ekwesị maka mgbasa ozi CATV RF ma ọ bụ Narrowcasting RF na eriri.
• VFD n'ihu panel na-egosiputa paramita ọkwa na ozi ọrụ.
• Nhọrọ njikwa netwọkụ SNMP.
• 1310nm wavelength nhọrọ.
