GWT3500 1550nm CATV watsawa
Bayanin Samfura
GWT3500 shine mai watsawa na 1550nm DFB kai tsaye don TV na analog, TV na dijital da siginar CMTS na rarraba fiber na gida da siginar QAM TV watsa fiber mai nisa. Mai watsawa yana amfani da babban layin DFB Laser, fasahar aiwatar da wutar lantarki ta atomatik na RF, tare da da'irar RF ta riga-kafi da Fasaha ta Greatway Technology ta haɓaka. Ginshikan microprocessor yana lura da yanayin aiki mai watsawa kuma yana tabbatar da kyakkyawan aiki ta atomatik. GWT3500 shine manufa don rarraba fiber na analog TV tsakanin 20Km da siginar QAM TV watsa nisa mai nisa tsakanin 100Km.
An gabatar da Fiber don watsa CATV RF a cikin 1990s saboda ƙarancin ƙarancinsa da kusan bandwidth mara iyaka. RF zuwa fiber Converter shine kayan aiki mafi mahimmanci. Tare da ƙaramar ƙarar amo da microprocessor, jimlar ƙarfin RF akan Laser ana iya saita shi daidai, tabbatar da mafi kyawun ƙirar ƙirar gani (OMI). Laser DFB da aka sanyaya a cikin mai watsawa yana tabbatar da tsayayyen tsayin gani na DWDM don watsa shirye-shirye ko shigar da sabis na mu'amala mai ƙunci. A halin yanzu sanyaya Laser DFB yana da mafi kyawun Laser RIN (ƙarar ƙarar ƙararrawa) da ƙarfin fitarwar Laser. Ortel-Emcore high linearity sanyaya DFB Laser da Greatway ƙira an tabbatar da zama mai nasara hade. GWT3500 na gani mai watsawa abokan ciniki sun yi amfani da shi sosai a Arewacin Amurka, Kudancin Amurka da China tare da kyakkyawan aiki da ingantaccen tabbaci.
Tare da babban ƙarfin gani na gani na gani na Greatway, GWT3500 mai watsawa na iya isar da fiber siginar TV mai inganci zuwa ginin ko fiber zuwa gida.
Wasu Fasaloli:
• Ƙananan amo high linearity Ortel-Emcore sanyaya DWDM DFB Laser.
• GaAs ko Fasahar GaN har zuwa 1218MHz.
• Kyakkyawan fasaha na zamani na inganta CTB, CSO da C/N.
• Gina-ginen microprocessor daidai yana kula da ƙarfin fitarwar Laser da zafin jiki.
• Mafi dacewa don watsa shirye-shiryen CATV RF ko Narrowcasting RF zuwa fiber.
VFD na gaba yana nuna sigogin matsayi da saƙon aiki.
• SNMP management cibiyar sadarwa na zaɓi.
• 1310nm tsayin raƙuman zaɓi na zaɓi.
