High Availability at the Air Traffic Control

SE “Oro navigacija” (Lithuanian Navigation Systems) is the sole provider of the air traffic services, the communications, navigation and surveillance services and the aeronautical information services in the airspace of the Republic of Lithuania for the needs of civil aviation.

The first step was to implement the project of extension its transmission network in conformity with the European Union requirements.

The starting signal for the cooperation was the signature of the Director General of SE “Oro navigacija” Algimantas Raščius and Director of JCSC “Dicto Citius“, representing MICROSENS, Edmundas Domeikis of a contract on procurement of the fibre optic data transmission equipment.

The procurement is a new phase of the investment project L-SWIM-01-I/V- C “Development of Data Exchange Network of the Enterprise” aimed at extending the DWDM data transmission network by connecting new objects and installing additional units as required.

MICROSENS equipment in all airports

In accordance with the contract the equipment under procurement has been installed in air traffic control centres of Vilnius, Kaunas, Palanga and Šiauliai, in all airports of Lithuania.

“Equipment must work over long distances without regenerating and it was the main demand from us” – said Andrius Kiaunė, Chief of Division of Information Communication Technologies in “Oro navigacija”. “The key aspect of aviation is safety. All data transfer infrastructure, like cables, may leave underground only in the buildings of Air Traffic Control Centers. This is why we can’t accept any inline regeneration. Only one company was able to offer such kind of solution. It was MICROSENS” – concludes Mr. Kiaunė.

MSP 3000 Optical Platform

MICROSENS delivered its Optical Transport Platform MSP 3000, the advanced system for long distance DWDM transmission. The system has been configured with 10G lambdas, with both native 10G Ethernet protocol and aggregation modules (enabling lower speed protocols support up from 100 Mbps). The system was designed to enable repeaterless transmission between all locations throughout the country. It means there are no inline amplifiers on any link, to assure the highest level of security for the network. Due to long distance links (the longest span is 290 km) Raman amplifiers have been included. Additionally, the system operates on a single fiber (instead of standard pair fiber operation), which is unique solution in such a long distance applications.

MICROSENS DWDM system is operating in ring topology thus full protection is assured for all the nodes in the network. This is especially important as the security of air traffic over Lithuania depends on proper operation of the transport network.

With the optical multiplexing solutions of MICROSENS, airport operators can safeguard their productivity by delivering the data volumes needed for modern converged networks with ease and at reasonable cost.
