Clear verdict in Schleswig-Holstein: FTTO is ideally suited for the Ministry of Justice

Universal and fast

"Once we had thoroughly analysed the starting situation, it was clear to us that the Fiber-to-the-Office concept was ideal for us", explains Dirk Strehl from the state construction / technical equipment department of the GMSH. The entire existing glass fiber infrastructure continues to be used, but the connections in the individual offices are replaced. This is possible with a Micro Switch, which is installed in the individual offices and takes care of the transition of the fiber-optic infrastructure to the copper cabling. The Microsens Micro Switches won the contract after the very first tender. As a result of the standardised 45 x 45 design, they can be installed without special tools. At the same time, they support Power-over-Ethernet, i.e. terminal devices can be supplied with electrical power directly via the data line, rendering an additional mains connection superfluous. On the output side, per Micro Switch four standardised RJ-45 connections with a 100Base-TX and a 100 Base-FX fiber-optic port are available for the users. Additional media converters are not required and after conversion all new terminal devices only need the copper-based LAN ports installed as standard. The Switches met a further criterion of the tender, as they support quality of service (QoS) and can therefore transmit Voice-over-IP. The central management of the Switches enables an integrated network management agent that supports SNMP.

Experience in handling glass fibers also played a major role in the selection of the service provider. Pigtails break very easily over the years if they are not used properly and a splice tray was not yet available at the time of initial installation. Here an IT service provider from Kiel won the contract in the first year; since 2009 euromicron systems GmbH has managed to secure the contracts.
