OTN Systems - Fibre-Optic Rail Communication Networks

OTN Systems designs, develops and markets dedicated fibre-optic communication networks for metros, light rail systems, people movers and railways worldwide.

The Open Transport Network (OTN) we provide is based on the latest fibre-optic technology and offers you the most reliable, open and easy-to-use system available on the market.

Digital rail-communications backbone

The OTN is a reliable and deterministic digital communication backbone for telephony, public address, passenger information systems, GSM-R, ERTMS, data, SCADA, LAN and CCTV that fully supports your operations. The OTN transmits all information between stations, trackside locations and the operations control room.

All applications can be connected directly to the broad range of interface cards, which are configured in the modular OTN nodes. In addition to Ethernet and IP-based applications, legacy applications (analogue and digital) can also connect easily to the OTN.

Long-distance fibre-optic communication system

The OTN nodes communicate with each other over a redundant optical fibre. This enables the transmission of a high bandwidth (e.g. 10Gb/s) over distances in excess of 100km. Furthermore, the optical fibre is immune to electromagnetic noise (EMC) caused by trains or trackside equipment.

Bandwidth management software

One of the unique features of the OTN is its capability to guarantee the availability of bandwidth to each application under all circumstances. To achieve this, bandwidth is provisioned for each network connection by OTN management software (OMS) during set-up. In this way bandwidth is allocated to each individual application so that it is always available, even in worst-case scenarios.

Modular OTN nodes

OTN nodes are 19in and rack-mountable, and have a modular design so they can easily be adapted to the type and amount of interfaces to be connected. All vital components can be equipped redundantly for maximum availability. The modularity of the system also facilitates maintenance and system modifications or expansions.

Network-based video surveillance and recording system

Because OTN is capable of providing a large, dedicated amount of bandwidth to specific applications, it is ideally suited for network-based video surveillance. Up to 1,000 camera images or more can be transported simultaneously over the OTN for viewing or recording on a network video recorder (NVR).

Reliable, cost-effective and easy-to-use rail communication network

The graphical user interface (GUI) of the OMS, the plug-and-play concept of the modular nodes and the advanced redundancy features ensure that the OTN is reliable and easy to use. This is why OTN users benefit from an extremely low total cost of ownership (TCO).

High-security rail communications system

The OTN provides unique features that limit the impact hackers can have on the communication and automation network. As the OTN transports each application in a separate channel, interference from one application on another is avoided.

Adaptable, future-proof rail communications network

Telecommunication backbones for transit systems have a life span of 10 to 15 years or more. Furthermore downtime for upgrades or updates has to be avoided or must be limited to a strict minimum. Therefore the design of the OTN ensures that it can grow with the increasing need for new applications, with limited or no downtime. To assist customers, OTN Systems also provides top-quality technical support for its products during their operational lifecycle.

It is OTN Systems' mission to provide innovative OTN solutions of the highest quality and reliability, coupled with best-in-class customer support.
