Research Of Split Backbone Microwave Communication System Technology

With the rapid development of microwave technology in the communication industry in recent years,multi-modal microwave communication devices have emerged one after another.Commonly,there are microwave transmission systems based on split-type,which are deployed in communication networks of major operators around the world.They are widely used in the Middle East and Africa regions,and the transmission capacity is also high.And for the construction of some large-capacity backbone communication links,the current indoor microwave system is the main one.Because the indoor microwave system has some disadvantages,such as the large feeder loss,low system gain and low link availability,How to improve the link performance of backbone microwave system is always a great challenge.Based on the practical application,this article proposes a set of split-type backbone microwave system for the large-capacity link,taking into account the advantages of the split type,and integrating into the backbone microwave communication equipment system.The link wireless simulation software Pathloss simulates the superiority of the split-type backbone microwave system in actual long-haul link communication compared with the actual transmission performance of the traditional all-indoor backbone microwave system.At the same time,through the design of the key device four-in-one combiner,the system gain under multi-channel fusion is effectively improved.For the backbone microwave communication system,the traditional indoor transmitter module is placed outdoors,which reduces the attenuation of the entire transmission system,and correspondingly improves the link performance reliability.For example,if there is insufficient space in the cabinet of the communication equipment room,and large-capacity backbone microwave link scenes such as the large-caliber antenna.If you consider placing the transmitter module outdoors,the split-type backbone microwave system will effectively avoid the risks and difficulties caused by these scenarios,and greatly improve the bandwidth and stability of long-haul links.
