Rosenberger OSI

Rosenberger OSI was founded in 1991 with the intention of production cables for the data communications sector.

Based in Ichenhausen in Bavaria, the company claims to be the first to supply high fibre PreCONNECT trunk systems for data centre cabling, which appeared in 1992. Due to the success of this product Rosenberger OSI expanded its sales operation in 1995 through branch offices in Germany and the rest of Europe. The same year saw the firm gain EN ISO 9001 quality management certification and two years later it extended its manufacturing facilities and established an operation in Hungary.

In 1998 there was a merger with Rosenberger HD-Technik, which led to more international growth. Rosenberger OSI introduced a PreCONNECT trunk system with 144 fibres in 2000 and a year later expanded its production operation in Hungary with the construction of a new. The MU and SC connectors series appeared in 2004 and four years later moved further into connection technology with production of the SC, LC and MU fibre optic devices. Rosenberger OSI also produces fibre optic components and cabling systems, copper cables and offers cabling and customised services.
