Smart digital microwave equipment(45Mb)
2009/4/30
    Smart series (45Mb)digital microwave equipments developed by our company is to fit the growing demand of broadcast digital transmission. System is mainly composed of high-performance antenna, outdoor unit (ODU), indoor unit (IDU) and the system cable. The transmission capacities are 45Mb (21E1), 1+0 / 1+1 working, providing service and channel monitoring additionally. The random provided local monitoring system software can effectively manage the device parameters.

     application

    for SDH microwave radio and television (optical) transmission networkisextension, or building independent transmission stations and are applicable to the building and connection of the public network or other private networks.

technical characteristics

Using Forward Error Correction technology, a superior error correction function.
Frequency, power adjustable.
Plus service and control channel, having a local monitoring function.
Interconnection only with a coaxial cable that can be up to 300 meters.
