Single source of services and cabling solutions for colocators


Colocation data centers must always provide state-of-the-art technology and outstanding scalability, while also ensuring compliance with standards. And these are just three of the many challenges confronting Multi-Tenant Data Centers (MTDC). This is because, on the one hand, customers expect a colocation space that is perfectly tailored to them and their business models. On the other, they also have very high expectations in terms of data center services. Relocations or extensions to the available space must be completed rapidly and new cable paths must be installed with no loss of time. At Rosenberger OSI, we both know and understand the challenges facing MTDC’s. Alongside our extensive portfolio of products for resilient, future-proof cabling infrastructures, we also offer a comprehensive range of services. Making us an expert, reliable partner for every aspect of co-location operation. From the equipment for the underlying infrastructure, through increases in the number of hosted tenants and on to consulting, installation and managed services. The benefits to you: With us, you can realize your specific individual expectations in practice expertly and immediately. With no loss of information or time and answers to all your warranty questions.

Saving in costs plus reduced space requirements through scalable cabling

For colocation providers in particular, the scalability of the cabling infrastructure is very important - especially in relation to cage and suite customers. These often only require incremental increases in bandwidth and fiber channels, which means your operational costs are only proportional to your current requirements. In the following video of our expert Luis Brücher you will get insides about modular cabling solutions that address some of these challenges.
