Volga DWDM System I DCI

Increase your network performance using our high-speed device

A feature of the data center infrastructure is the presence of cold and hot aisles and the corresponding equipment cooling scheme in the data center. An important requirement for telecom equipment is the support of high-speed clients, their efficient aggregation in a high bandwidth channel.

DCI chassis allow operators to set up high-capacity DWDM links to connect data centers within a city or over longer distances. Through the compact platform it is possible both effectively accommodate up to 2 (V3 DCI) or 6 (V6 DCI) high-speed aggregators, and an optical line system in one chassis.

With the help of line cards of the M1200 line in the DCI version, it is possible to organize information transfer up to 2.4 Tbit/s in one V3 DCI chassis, and up to 7.2 Tbit/s in the V6 DCI chassis.

Responding to the needs of data center clients, within the framework of the DCI line, T8 has developed cards with a wide range of multi-service client interfaces. For example, the M400-2C2-20P2Q-DCI Aggregator supports high-speed FibreChannel storage protocol options along with Ethernet clients up to 400GE.

Compact monoblock solutions

The transceiver units and optical equipment of Volga line can be implemented in a compact 1U package. Such a monoblock design is an independent system with integrated control units. Monoblocks can be implemented both with the classic "left to right" blowing option, and in the data center version, with "front to back" blowing.
A distinctive feature of 1U solutions is the ability to organize networks with personalized data processing algorithms.
Such compact solutions are in demand in the banking sector, where security issues are in the first place.
