 The Product Summary


AOT1000 all-digital video optical transmitter and receiver seriais are our self-developed products on the base of Chinese application features and ASIA OPTIC has intellectual property rights to these optical fiber communication eauipment,whitch integrate vidio,audio,video,data and Ethernet.

AOT1000 digital video optical trnsmitter and receiver adopts international advanced technique of digital video and bega optical fiber high-speed transmission so that it can ensure the distortionless and high quality transmission of 1-channel vidio and the signals of audio,data,Ethernet,phone,etc on single core or twin-core.

AOT1000 digital video optical transmitter and receiver adopts all-digital non-condensing technique and sustains distortionless transmissin of high definition movement and static images.AOT1000 digital video optical transmitter and receiver conquered the deficiencies of traditional analog frequency modulation, phase modulation and amplitude modulation optical transmitter and receiver,such as mitual interference of the transmission of multiplexing signals on one optical fiber,subject to interference of the workong conditions,low transmitting quality and poor stability.

 The roduct characteristic 
◆ It is compatible voluntarily PAL、NTSC、SECAM vidio standard
◆ The complete digital and non-condensing broadcst quality
◆ Broadcst singals of video and miltichannel unilateralism or bidirectional RS232、RS422、485
◆ perform in self-adaptive synchronous mode and supports numerous signals in different definition formats
◆ Transmission range 5-80KM ,the biggest transmission range attainability 100Km
◆ Can be installed rapidly without customer adjustment, and they are easy to operate and maintain
◆ Support at the same time the vidio and the data and the Ethernet and the telephone concurrent transmission
◆ Ultrahigh speed optical fiber transmission technique
◆ Completely use SMD technique
◆ The reliability is high to the industry level design
◆ Custom-tailor and method of OEM are supported
