Volga multiservice platform

Increase your network performance using our high-speed device

High-speed multiservice and multiprotocol DWDM platform Volga consists of the range of chassis with different capacities and optimized for various optical network deployments: from compact solutions for distance increasing of existing city and regional networks or data center interconnect for organization of high capacity and long-haul transport infrastructure. The total capacity of the system is up to 30 Tbit/s. All chassis of DWDM-platform Volga use common software and hardware, control and monitoring systems, ensuring compatibility, manageability and interchangeability of modules in all product lines.

  • 5 chassis types;
  • Support up to 400G;
  • Optical amplifiers: EDFA, RAMAN and gybrid EDFA+RAMAN;
  • ROADM: WSS 1x1, 1x2, 1x4, 1x9;
  • Redundant AC/DC power supplies: 650, 850, 1200 or 1600W.

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
Transmission of up to 96 DWDM channels, up to 100 Gbit/s or 400Gbit/s each. Transponders support various line speeds 400, 200, 100, 40, 10, 2.5G and less. A hot upgrade without traffic interruption is possible. Coherent detection and HD-FEC/SD-FEC/Soft-FEC in 400G/100/40/10G transponders makes a transmission characteristics of these transponders very solid and enables them to work in old lines together with existing 2,5G channels. Volga supports up to 270 channels in expanded C+L band.

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
    • Aggregators 4x100G, 20x10G, 10x10G, 8x1.25G, 4x2.5G, 21x2Mb

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”.
