With high-speed through Passau: Telepark offers secure fiber optic network for all

Multiplied Capacity

Telepark Passau decided to couple both locations for wavelength multiplexing, or specifically: for Coarse Wave Division Multiplexing (CWDM). The optical multiplexing procedure enables the city carrier from lower Bavaria to multiply the capacity of its existing fiber optic trunks in a cost-effective way. The parallel transfer of several wavelengths over a fiber pair makes it possible to reach transmission capacities of several hundred Gigabits per second without the necessity to install additional optical fibers. With regard to the components, Matthias Weindler, network specialist of Telepark, particularly focusses on the reliability of the systems: "Ideal devices are those which you pass by after years and see that they continue running without any problems after all this time," explains the IT expert, grinning. He has had positive experiences like this with media converters of MICROSENS for several years now. This was ample reason for him to take a closer look at the xWDM solutions of the German vendor.

Simplified Operation

The systems of the MICROSENS Optical Transport Platform won over Telepark Passau immediately: They can be configured easily and quickly by means of a homogeneous management software. Both the administration and the long-term maintenance of the components are simplified by means of optimised configuration options. In addition, the modular setup of the systems is ideally suited for the application by the city carrier. The chassis can be equipped individually with different modules according to demand. The modules, in turn, can be complemented or replaced any time. Matthias Weindler explains: "We could even use an existing MICROSENS chassis, since the media converters originally contained in it were superfluous to a large extent. This enabled us to save much space in the rack and to reduce reassembly times, as we only had to put the new CWDM cards into operation."

Reliable Technology

Today, both sites are interconnected by means of two data connections set up in a ring-shaped structure. For security reasons, the redundant trunk uses another route and is somewhat longer because of that. Multiple services are running on the two optical fibers, which can draw on a total bandwidth of 90 to 100 Gbps. Most systems can easily be coupled over CWDM by means of integrated modules, so-called SFPs. Alternatively, there is always the option to use a media converter. Telepark selected this option for the storage systems of EMC, which also exchange data over CWDM. "The consultants of MICROSENS always answered our questions on this subject matter quickly and competently. The service of the German vendor is really excellent," states Matthias Weindler. The satisfaction of the customer is reflected in the fact that he recommended the services of MICROSENS to his colleague Sebastian Krückl, who is responsible for the networking of a new Telepark building as a project manager. In cooperation with SKM Skyline, Telepark Passau has also installed MICROSENS products on the LAN sector in the meantime: all floor boxes of the new building were equipped with the practical FTTO installation switches.
