As the technology of satellite television developing fast, as the unique advantage of DBS, its developing so quickly and meanwhile, cause the competition and amalgamation of the DVB-S, DVB-T and DVB-C three TV network.
Guangtai HT9500, just in order to apply to this network technology, due to our own technology develop a new broadband type 1550nm External Modulation Optical Transmitter, through multiplexing the frequency, can enlarge the broadcast CATV available band width from 47~862MHz to 47~2700MHz. Not only it can be used into 47~862MHz of analogue digital video transmission, but also transmit in the IF/SAT of 950~2700MHz. It provide a whole set of high quality, low cost of optical trunk transition and FTTB, FTTH solution for mixed of DBS and CATV.
HT9500 adopts low noise, narrow bandwidth, continuous wave laser as light source and American JDS-U LiNbO3 external modulator as signal modulation, due to adopting owned system optimized control technology & using top class parts. All equipment has complete RS232 communication interface, SNMP network management and 1+1 power back up optional, machine temperature control automatically, and it ensures high reliability and cost performance of the whole unit.
HT9520C: dual fiber output, CATV operating wavelength, CNR≥53.5dB, SBS: 13~19dBm adjustable.
HT9520U: dual fiber output, ITU wavelength adjustable, CNR≥53.5dB, SBS, 13~19dBm adjustable.
HT9510C: single fiber output, CATV operating wavelength, CNR≥52dB, SBS: 13dBm.
HT9510U: single fiber output, ITU wavelength adjustable, CNR≥52dB, SBS: 13dBm.
