HT3510C,HT3510U

MMDS will influenced by the meteorological factor, cause the quality of transmit signal is not very steady, and also will due to the areas that bring much trouble on the construction of work station.

Huatai HT3510 External Modulation Optical Transmitter is specially design and produce for MMDS to relay and transmit in a long distance. The equipment 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.

Huatai HT3510 External Modulation Optical Transmitter, fiber amplifier and DBS optical receiver, as for MMDS to relay and transmit in along distance, it provide a whole set of high quality, high reliability and low cost of proposal of fiber transition. HT3510 works in 950~2700MHz bandwidth, all transparent work mode, low XM distortion, and also can use in the DBS and other digital broadcast and commutation.

HT3510C work in 1548~1563nm wavelength, be applicable in the daily application of signal wavelength.
HT3510U ITU standard wavelength, adjustable wavelength, be applicable in the WDM system.
