Systems DWDM, SDH and PDH for the primary communications networks


Comita Group of Companies has a full range of modern equipment for the installations of hypervelocity trunk-road communications networks:

The new generation of multifunctional multi-service optical transport platform enables building flexible and scalable optical networks with the possibility to transmit all kind of traffic (Ethernet, OTN, SDH, Sonet, Fibre chanel), with the capacity to 800 Gbit / s the support of line interface OTN/DWDM and the client interface 100 Gb / s, 10 Gb / s as well the general client and line interfaces. The platform allows also to build the networks of various topology from the simple point to point connection till complex mixed city (metro), regional and truck-road networks. There is also the possibility to connect networks which are based on different technologies.

For the installing of multiservice networks based on line connection SDH / PDH there is the equipment of compact SDH multiplexers for the organization of high-speed access with broad possibilities to combine PDH (E1, E3), SDH (STM-1/4/16) and the IP (FE, GbE) traffic.
