Smart series(4/8/17/34Mb)
2009/4/30
 

       To fit the growing demand of digital transmission, basing on long-term of digital microwave communication equipment manufacture, we designed the third generation of digital microwave equipments, smart series (4/8/17/34Mb) with high cost-effective. This series equipment is a narrow-band point-to-point digital microwave relay system, using large amount of import components. The equipment is small in size, light in weight, fast in connection, flexible in networking, adaptive in complex terrains and stable in performance. Smart series are already used in telecommunications, electricity, radio, television, military, agriculture and various professional networks. Particularly applicable for the base stations' transmission among China Mobile,China Unicom,China Netcom,China Railway Telecom and network connections of enterprises and colleges. As a quick connect device, it is widely used in temporary and emergency communications. System is mainly composed of high-performance antenna, outdoor unit (ODU), indoor unit (IDU) and the system cable. The transmission capacities are 4E1 (8Mb), 8E1 (17Mb), 16E1 (34Mb), 1+0 / 1+1 working, providing service and channel monitoring additionally. The random provided local monitoring system software can effectively manage the device parameters.

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.
With a proximal loop, remote loop-back testing. Interconnection only with a coaxial cable that can be up to 300 meters.

Typical application:
