GWT3500S CATV+SAT 1550nm Optical Transmitter
Nkọwa ngwaahịa
GWT3500S bụ modulation 1550nm DFB laser transmitter maka nkesa oke eriri. GWT3500S nwere otu mmepụta eriri na ntinye RF abụọ: otu maka 45 ~ 806MHz 80ch analog CATV ma ọ bụ DVB-C QAM ma ọ bụ DVB-T na nke ọzọ maka 950 ~ 2150MHz Satellite Input. GWT3500S nwere ike nnyefe analọg TV, DVB-C / T TV na DVB-S / S2 satellite TV n'elu ọ bụla FTTH usoro. Ya na nnukwu ike ngwa anya ampilifaya, GWT3500S na-enyere FTTH MSO na-enye analọg TV, DTT ma ọ bụ DVB-C, na ndụ satịlaịtị video site na otu ngwa anya transmitter.
Ọtụtụ RF TV na-agbasa ozi na isi CATV sitere na modulators vidiyo mpaghara, mgbanwe vidiyo satịlaịtị ahọpụtara yana mmepụta QAM ịntanetị. N'ezie, ọ bụghị akụ na ụba iji tọghata satịlaịtị TV niile na CATV ma ọ bụrụ na isi satịlaịtị nwere ọtụtụ ọdịnaya TV a ma ama. Ọ na-arụ ọrụ nke ọma iji kesaa akara satịlaịtị yana CATV RF. Site na ọtụtụ usoro FTTH na-ebuga GPON maka ọrụ ịntanetị, enwere ike ịgbatị bandwidth CATV na-aga n'ihu RF ruo 45 ~ 2150MHz, gụnyere nnukwu mgbasa ozi CATV na Satellite TV. Site na teknụzụ DWDM, GWT3500S na-emekọ CATV RF na satịlaịtị TV RF iche, na-ahụ na arụmọrụ RF kacha mma na band CATV na satịlaịtị otu.
GWT3500S na-enye analọg TV, DVB-C/T/S ọrụ na a mfe ụzọ. Mgbe nnukwu vidiyo dị elu na-agbasa na windo ngwa anya 1550nm, ọrụ ịntanetị nwere bandwidth dị irè karị. GWT3500S nwere ike ịrụ ọrụ na GPON, XGPON, NGPON2 FTTH usoro.
Atụmatụ ndị ọzọ:
•Obere mkpọtụ elu linearity DFB laser.
•Ntinye CATV RF nọọrọ onwe ya yana ntinye RF Satellite.
•Nkwado ruo 32 transponders na satịlaịtị 950 ~ 2150MHz RF.
•Na-akwado ruo 80ch NTSC analog TV ma ọ bụ QAM na 45 ~ 806MHz RF.
•Ogwe ihu VFD na-egosiputa paramita ọkwa yana ozi ọrụ.
