Ingcaciso yeMveliso
I-GLB3500M yimodyuli 45~2600MHz RF phezu kwekhonkco lefayibha, isasaza amajelo eTV eTerestrial kunye ne-L-Band RF enye ngaphezulu kwefayibha enye.
ISathelayithi yoSasazo oluNgqo (i-DBS) kunye neNgqo kwiKhaya (DTH) yeyona ndlela idumileyo yokonwabela iTV yesathelayithi kwihlabathi jikelele. Ukwenza oko, i-antenna yesathelayithi, intambo ye-coaxial, i-splitter okanye i-multi-switcher kunye ne-satellite receiver iyimfuneko. Nangona kunjalo, ukufakela i-eriyali yesathelayithi kunokuba nzima kubabhalisi abahlala ezindlini. I-SMATV (i-satellite mater antenna TV) sisisombululo esihle kubantu abahlala kwisakhiwo okanye kuluntu ukuba babelane ngesitya esinye se-satellite kunye ne-antenna ye-TV yomhlaba. Ngentambo yefiber, i-SMATV RF isignali inokuhanjiswa kwi-30Km kude okanye isasazwe kumagumbi angama-32 ngokuthe ngqo, ukuya kuma-320 okanye angama-3200 okanye amagumbi angama-32000 nge-GWA3530 fiber optic amplifier.
I-GLB3500M inemodyuli yothumelo ye-GLB3500MT kunye nemodyuli yomamkeli we-GLB3500MR. Imodyuli yothumelo ye-GLB3500MT inezibuko elinye okanye ezimbini zeRF ngelixa i-GLB3500MR inezibuko elinye le-RF yokuphuma. Ngomgca ophezulu we-1550nm we-laser ye-DFB engapholiswanga, i-photodiode kunye nengxolo ephantsi ye-RF yolawulo lwesekethe yokulawula, i-GLB3500MT inokunikezela ngezitishi ze-TV ezikumgangatho ophezulu kunye ne-RF yesathelayithi phezu kwefayibha kubabhalisi abambalwa ngokuthe ngqo okanye amawaka ababhalisile be-FTTH nge-EDFA. Nge-1310nm/1490nm/1550nm inketho ye-WDM, i-GLB3500M inokufaka i-L-Band+TV RF phezu kweGPON/GEPON. Ngaphandle kwenguqulelo yeemodyuli, i-GLB3500M inokuba ne-19”1RU inguqulelo xa iceliwe. Ifayibha kwinguqulelo yendlu yeplastiki yendlu ye-GLB3500MR yi-GFH2000 i-LNB yokubona, apho umrhumi we-FTTH efuna nje i-fiber enye kwaye akhuphe iimpawu zesathelayithi kumagumbi aliqela kusapho.
Ezinye iimpawu:
• I-aluminiyamu ediyiweyo yendlu yesamente.
• Igalelo le-RF enye edityanisiweyo kunye ne-bandwidth: 45 ~ 2600MHz okanye.
• Amagalelo eRF ahlukeneyo, kuquka:
-Igalelo leTV enye yeTerestrial, i-bandwidth: 174 -806 MHz.
-Enye igalelo le-LNB RF, i-bandwidth: 950MHz ~ 2150MHz (13V okanye i-18V DC ukhetho lwe-LNB ngesicelo).
• Izibuko le-RF enye.
• ILinearity ephezulu ye-1550nm engapholiswanga ye-DFB Laser kunye ne-Photodiode.
• Ingxolo ephantsi yoLawulo lweRF I-Receiver Node, Ukuba unomdla kuyo nayiphi na imveliso, nceda uzive ukhululekile ukuqhagamshelana nathi ngolwazi olungakumbi okanye nceda usithumelele i-imeyile ngokuthe ngqo, siya kukuphendula kwiiyure ze-24 kwaye i-quotation engcono kakhulu iya kunikwa.
Iminyaka eyi-18 yeFactoryI-China i-Optical Receiver / i-Node kunye ne-FTTH CATV i-Optical Receiver, Siye sahlala sigxininisa ekuveleni kwezisombululo, sichithe iimali ezilungileyo kunye nabasebenzi ekuphuculeni iteknoloji, kwaye siququzelele ukuphuculwa kwemveliso, ukuhlangabezana neemfuno zamathemba avela kuwo onke amazwe kunye nemimandla.
