 Transmission equipment STM-1 on the radio-relay link


           In the last few years network operators are facing rapid growth and fast migration from TDM to packed traffic. The main challenge is how to optimize investments and reduce maintenance costs. The transition from legacy circuit network (TDM) to high-speed packet network is rapid and new equipment must support both technologies. New telecom operators need low entry and operational costs, but also scalable equipment in order to follow future market developments.
          SparkWave is optimized for different propagation conditions in different weather conditions. In many cases, spectrum economy plays a major role in considerably reducing operating costs.

          The equipment SparkWave series has different outdoor and indoor radio relay units. SparkWave SDR indoor unit is modular. Different housings and high integration level allow easy interconnection, stacking with ESSI interface and direct connection to existent F/O networks. Outdoor units (ODU) is connected to the IDU via single coaxial cable up to 400 m. The outdoor units are connected to antennas using waveguide up to 1.8 m.     

          The SparkWave SDR STM-1 is intended for microwave transmission of STM-1 traffic, operating in 5, 6, 7, 8, 11, 13, 15, 18, 23 and 26 GHz frequency range. 

          Split Mount solution with STM-1 IDU and compact ODU. The STM-1 tributary interface can be optical or electrical. An additional 2Mbit/s wayside channel per traffic channel is available. Configurations 2+0 and 1+1 with the possibility of using the stand-by connection for low priority traffic are possible.
          A management system with an SNMP agent and a OSPF router is built into the unit. No additional equipment is needed except a standard PC computer with built-in web browser.
          The unit enables operation in ATPC (Automatic Transmitted Power Control) mode.
