SDR ADM SDH radio-relay add/drop multiplexer

 SDH radio-relay add/drop multiplexer


           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 is intended for microwave transmission of operating in 5, 6, 7, 8, 11, 13, 15, 18, 23 and 26 GHz frequency range. Powerful multi service SDH ADM-1/4 multiplexer is integral part of the radio IDU.

          Any ADM combination (optical/electrical-radio, radio-radio or optical/electricaloptical/ electrical) is possible. The capacity of radio links and electrical interfaces is STM-1. Optical interfaces can be STM-1 or STM-4 Many different radio and SDH protection mechanisms are available. Split Mount solution with ADM IDU and compact ODU. Various tributary interfaces (E1, E3, Ethernet 10/100/1000), a powerful cross-connect matrix (16XSTM-1 equivalent) and stacking connectivity gives opportunity for powerful, flexible and effective SDH optical and/or radio solutions.
           A management system with an SNMP agent and a OSPF router is built into the unit. No additional equipment except a standard PC computer with built-in web browser is needed.
          The unit enables operation in ATPC (Automatic Transmitted Power Control)mode..
