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.
