Volga multiservice platform


Increase your network performance using our high-speed device

The Volga multi-service platform family for high-speed DWDM networks. Supports channel speeds of up to 600 Gbit / s, up to 28 Tbit / s in one fiber pair. The chassis of the Volga platform is mounted in standard 19/21 ”telecommunication racks. Volga is optimized for working with high-speed transponders: 100, 200, 400 and 600 Gbit / s.


  • Range of chassis height from 1 to 10U.
  • Transponders and muxponders up to 600 Gbit / s per channel.
  • Optical amplifiers: EDFA, RAMAN and hybrid EDFA + RAMAN.
  • ROADM: WSS 1x1, 1x2, 1x4, 1x9.
  • Power supplies: 1200 and 1600 watts.


The Volga platform has EC declaration of conformity in accordance with the requirements of the European Union. The objects of the declaration correspond to the relevant legislative acts of the legislation on the Union 2014/30 / EU; 2014/35 / EC; 2011/65 / EC.

High channel capacity
The system provides up to 28 Tbit / s in the C-band on the pair of fibers. Data transmission in each spectral channel is performed at speeds of 600, 400, 200, 100, 40, 10 Gbit / s and less. Reconfiguration of the network and its expansion can be carried out without interruption of traffic. The high quality of the signal on the transponders allows you to include channels on existing lines, built earlier for the organization of low-speed channels. Support for proactive FEC error correction, including Super-FEC, Soft-FEC and HD-FEC, provides significant operational margin and significantly increases the length of the regeneration section.

OTN technology support
Transponders and muxponders-aggregators transfer traffic in the OTN OTU1/2/3/4 format. OTN capacity matrix up to 200 Gbit/s. The possibility of using an alien wavelength allows customers to organize cost-effective solutions using already using equipment. Next generation will support OTN-matrix up to 1Tbit/s.

Implementation of complex topologies
Due to using of WSS ROADM 1x2, 1x4, 1x9 and different types of aggregators and path-protection cards the Volga platform perfectly fits for constructing different topologies DWDM networks: with 1+1 protection, both ring and mesh. High speed optical end electronic switches, powerful digital signal processor in 100G transponders make possible to build redundant links with very fast reconfiguration (<50 ms) in case of failure.

    • ROADM is a flexible input/output of optical channels for network protection and upgrade
    • BS blocks - optical redundancy of 1 + 1 line traffic
    • A wide range of aggregators for any requirements and tasks

Wide range of optical amplifiers
Low-noise erbium-doped fiber amplifiers (EDFA), Raman amplifiers (Raman) with a power of up to 30 dBm, remote optically pumped amplifiers (ROPA), hybrid amplifiers EDFA + Raman. Due to high fault-tolerance of 100G DWDM transponder, the transmission on distances of up to 4250 km without dispersion compensators in the line with cascade of amplifiers is possible, as well as the 500 km point-to-point transmission with the use of Remote Optically Pumped Amplifiers (ROPA).

Fractal network management system
Enables control and management of all nodes at the network map. The system provides information about the status of network elements with minimal delay. Management of distributed administrative domains. The graphical framework Fractal and the built-in Web-server significantly simplify operations on remote configuring of the Volga platform.

Dimensions and power consumption
Chassis options allow you to easily and efficiently increase the capacity of your network by adding only the required blocks and replacing the chassis with a larger chassis if necessary. Doubled power units: DC 36–72 V or AC 220 V 50Hz. Chassis options height 1, 3, 6U and 10U. Chassis depth 300 mm for standard telecommunications rack 19/21”.
