OTN Systems Fibre-Optic Communication Networks for the Airport Industry

OTN Systems designs, develops and markets dedicated fibre-optic communications networks for airports worldwide. The open transport network (OTN) is based on the latest fibre-optic technology and offers you the most reliable, open and easy-to-use system available on the market.

Open transport network for airport communications

OTN is a reliable multi-service communication backbone for passenger information services, telephony, public address, building automation, LAN and CCTV that fully supports your operations. OTN transmits all of the information between the gates, terminals and the operations control room. As the OTN provides integrated H.264 video encoding, existing analogue CCTV cameras can be integrated easily and combined with megapixel IP cameras in a single networked video solution.

Open transport network for interconnecting air traffic control applications

OTN’s reliability and capability to support legacy interfaces make it ideally suited to interconnect air traffic control (ATC) applications. The OTN transmits all of the information between the radar sites and the ATC control room in real-time and in a transparent and redundant way.

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.

Modular OTN nodes

OTN nodes are 19in rack-mountable, and have a modular design so they can be easily 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.

High-capacity fibre-optic communication system

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

Reliable bandwidth management

One of OTN’s unique features 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.

Networked video surveillance and recording system

OTN is capable of providing a large, dedicated amount of bandwidth to specific applications, which makes it ideally suited for network-based video surveillance. More than 2,000 camera images can be transported simultaneously over the OTN for viewing or recording on a network video recorder (NVR). In this way the operations control room can have live video feeds covering the whole installation. The recorded images can be stored in redundant sites for disaster recovery.

Cost-effective airport 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 OTN is reliable and easy to use. This is why OTN users benefit from an extremely low total cost of ownership (TCO).

Adaptable airport communication networks

Airports are dynamic environments so communications networks have to adapt to the constantly changing conditions. Downtime for upgrades or updates has to be avoided, so the design of the OTN ensures that it can adapt to new requirements and grow with the need for new applications, with limited or no downtime.

Technical support

To assist customers, OTN Systems provides top-quality technical support for its products during their operational lifecycle of 10 to 15 years.

It is OTN Systems’ mission to provide innovative OTN solutions of the highest quality and reliability coupled with best-in-class customer support. You can experience OTN at airports and in ATC networks around the world. Please contact us if you would like to receive more information.
