The digitalisation of the railway sector is increasing the demands placed on telecommunications infrastructure. Railway stations, technological facilities, video surveillance systems, information services and other distributed systems require reliable broadband connectivity along railway sections.
One technological approach to building such infrastructure is PON — a Passive Optical Network. It enables data transmission between a large number of geographically distributed facilities and provides a foundation for connecting various technological and information services.
Iskratel Lumia solutions from the Slovenian company Kontron support GPON, XGS-PON and P2P technologies, enabling the deployment of scalable optical access networks tailored to the specific requirements of each railway section.
An optical network can be used to transmit data from technological systems, IP services, video surveillance systems and other applications. This makes it possible to consolidate different types of traffic within a shared telecommunications infrastructure and provide centralised network management.
The network architecture, bandwidth and level of redundancy are determined based on the requirements of each service, the number and location of connected facilities, and the criticality of the respective systems.
Solutions based on Iskratel Lumia enable the gradual development of optical infrastructure and a phased transition from GPON to XGS-PON as bandwidth requirements increase and new services are introduced.
This approach makes it possible to modernise the network in line with current needs while providing opportunities for future expansion without having to replace the entire infrastructure at once. Railway telecommunications infrastructure may include both fully equipped technical premises and remote facilities or outdoor telecommunications cabinets.
Depending on its configuration and design, Iskratel access equipment can operate within an extended temperature range. This makes it possible to select an appropriate solution for the specific operating conditions of each facility.
Maintaining service availability in the event of damage to individual network sections is particularly important for critical infrastructure.
PON architectures can incorporate various equipment redundancy and optical line protection schemes. The choice of a specific scheme depends on the network topology, the location of connected facilities, service availability requirements and the acceptable recovery time.
A carefully designed redundancy architecture helps minimise the impact of optical fibre damage or the failure of an individual component on connected systems.
Ukraine’s railway network covers a vast area and includes a large number of geographically distributed facilities. Its modernisation requires telecommunications solutions that combine scalability, centralised management and redundancy capabilities.
Optical infrastructure can provide the foundation for connecting railway stations, technological facilities, video surveillance systems and information services. At the same time, the design of such a network must consider the characteristics of each railway section, bandwidth requirements, operating conditions and the criticality of every connected system.
Kontron has experience in developing telecommunications solutions for the carrier and transport sectors. The Iskratel portfolio includes optical access equipment for building networks of various scales and purposes.
ISTEL 3000 is the sole authorised partner of Kontron (TM Iskratel) in Ukraine. The company provides a comprehensive approach to the construction and modernisation of railway telecommunications infrastructure — from needs assessment, network architecture design and equipment selection to integration, commissioning and ongoing technical support.
This approach makes it possible to develop a solution that considers the topology of the railway section, the existing infrastructure, the range of connected services and the required level of network resilience.
Sincerely,
The ISTEL 3000 Team
