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 very different propagation conditions in different weather conditions.

System description

All SparkWave product lines have standard split mount design. According to project needs there are different indoor and outdoor units adjusted to specifics of the market. Special applications such as all indoor are also available.

SparkWave SDR indoor unit product line has a modular concept. Different housings and high integration level allow easy interconnection, stacking with ESSI interface and direct connection to existent F/O networks.

SparkWave Outdoor Units

The outdoor units are part of the system and are designed in order to support the following requirements:

  • QAM modulation 4,16, 32, 64, 128 and 256 QAM
  • FEC using various coding schemes
  • Standard and Extended Temperature range
  • Standard and High Output Power
  • Direct integration to antenna (up to 1.8m)
  • Integration with waveguide (antennas > 1.8m) *
  • Power Divider (in case of redundancy with single polarized antennas)
  • Compact ODU connected to the IDU via single coaxial cable up to 400 m
  • ATPC reducing interference in dense networks
  • ACM – Adaptive Coding and Modulation
  • QoS – Quality of Service for packet transmission

In case of redundancy with single polarized antennas a compact Power Divider is available.
As alternative, in the frequency ranges from 5 to 13 GHz, all-indoor construction is also available. In this case the radio unit and antenna are connected via elliptical wave-guide.

SparkWave Indoor units

Thanks to the modular concept the SparkWave SDR can be easily and quickly adapted to different requirements of both fixed and mobile telecommunication networks, enterprise networks, government administration and campus networks. The short implementation time to market, from network design to network deployment, allows cost effective merging of LANs, PBXs, intranets and telephone systems for administration.

SparkWave SDR HSP

SparkWave SDR HSP (High Speed PDH) is designed for low, mid and high capacity PDH and Ethernet transmission. Any combination of PDH signals (E1/E3) and Ethernet is possible from 2x2 up to 72x2 Mbps capacity, full duplex. SparkWave SDR HSP devices operating in 5-8 GHz frequency bands are used for long haul connections, up to 80 km.

SparkWave SDR ADM

SparkWave SDR ADM is a powerful device designed for more demanding clients such as telecom operators, utilities, gas and oil companies, highways and railways. Complete NG SDH add/drop multiplexer with a powerful 2.5GB/s cross-connect matrix and EoS with GFP, LCAS, VCAT is integrated into IDU. It supports all PDH/SDH/FE/GE interfaces.

SparkWave SDR STM

SparkWave SDR STM is designed for transmission of NxSTM-1 signals. The device operates as an SDH regenerator. The tributary interface can be optical or electrical. SparkWave SDR STM is most efficient where pure STM-1 transmission without cross-connect is required.

SparkWave SDR GE

SparkWave SDR GE is a high performance Ethernet radio designed for 3G, Wimax, LTE and data operators with maximum capacity up to 400Mbps. ACM (Adaptive Coding & Modulation) in combination with QoS (Quality of Service) guarantees maximal spectral efficiency, while preserving transmission of real-time critical services without latency variation, even in case of bad weather or other propagation conditions.

Active repeater SparkWave AR-7/8/13/18/23G

Active repeater SparkWave AR-7/8/13/18/23G is applicable in cases of long transmission paths, where no line of sight is available and where inconvenient angles prevent the use of a passive repeater. The angle between two antennas can vary from few degrees to up to 180 degrees. Low power consumption allows use of a solar panel. The built-in storage battery assures autonomy in the case of long-term bad weather.

Management

Complete Element Management system (EMS) software is stored on equipment: only a standard computer with built-in web browser is needed for complete local or remote management.
Central management can be performed by any open SNMP based central management system or by very powerful and effective SparkView NEMS, which allows you to manage all the devices produced by Iskra Sistemi, as well as other SNMP compatible devices.
