Solutions

Unique operator solutions for optical networks offered by engineers of our Company are based on benefits and features of CWDM and DWDM wavelength division multiplexing systems.

 

Wavelength division multiplexing technologies allow to arrange a duplex transmission of multiple data streams via a single optical fiber at different carrier frequencies. Due to the fact that multiplexing systems support all data transmission protocols, various telecommunications services, such as data transmission, voice communication, and multimedia, can be implemented in one transport medium.

 

Wavelength division multiplexing systems provide operators with flexible opportunities of traffic delivery both through the construction of new network architectures and on the basis of existing networks.

 

Using fibers of a previously constructed optic transport network provides significant cost savings for construction and modification of fiber lines, nodes, fiber lease.

 

Our Company offers to implement any of the projects to build or upgrade the optical network based on our proven special solutions. We take basic solutions developed by our engineers as the basis for the construction of a customized network scheme.

DWDM Passive Systems

The main application of DWDM passive systems is metro networks, as well as high-speed communication lines with a high channel capacity. Unlike active backbone networks with amplifiers and dispersion compensators, the passive DWDM allows to arrange a high-speed system having high channel capacity with substantial cost savings.
