3. Technological Characteristics
Traditional digital microwave equipment generally transmits E1 signal only, so there is
always the need to apply for frequency channel because of technological limitations.
In recent years, there is a dramatic change in the structure, composition and application
of digital microwave communicative equipment. The traditional system of transmission
has been changed to the integration of transmitter and receiver as well as from fixed
frequency to the possibility of frequency conversion from low to high frequency band. In
view of the high frequency digital microwave communication system’s new changes and
additional newer characteristics, we had already improved the traditional system to a
great length.
K-Best’s PDH system has the following technological characteristics:
-- high frequency band: 5.8、13、15GHz to 26GHz
-- complete capacity: 2*2Mbps、4*2Mbps、8*2Mbps、16*2 Mbps
-- flexible interface: suitable for multiple network and business connection
-- IDU and ODU unit connected by a single IF cable up to 300m length, thereby,
decreasing the RF transmitting loss and increasing the receiving signal-to-noise ratio
(S/N)
-- channel conversion, flexible spread network and least backup support
-- digitally advanced QPSK or 16QAM de/modulation
-- powerful monitoring function: simple and easy to operate LCD display. With the overall
status display and loopback test function, subscribers can easily maintain the system
without the need of special equipment to ascertain where malfunction has occurred
-- improved SNMP network management system suit a lot of different topological
structure. It can manage up to 255 number of station equipments and also extend the
monitoring support to other microwave equipments
-- quick and easy installation
-- equipment adopt a considerable amount of advanced technology and modularity to
design the structure which is highly reliable, small, artistic, quick to produce and easy
to maintain.
-- frequency bandwidth and spectrum transmitting RF spurious fits the specifications
