Mainzer Breitband is a regional provider in Mainz and the surrounding area and a wholly owned subsidiary of Mainzer Stadtwerke AG. The company’s proprietary fiber-optic network already offers high connection density, particularly in industrial and mixed-use commercial zones. Additionally, the network is being expanded to meet the needs of business customers. The product portfolio includes internet and site networking with bandwidths of up to 100 Gbit/s, as well as Wi-Fi solutions and dark fiber connections. In addition to business customer products, Mainzer Breitband also offers residential customer products in certain areas, such as the Heiligkreuz district and the Hildegardis area.

On this website, you will find the expansion projects of telecommunications companies that are carrying them out under their own names. However, the completed fiber-optic network can often be used later by other companies—that is, third-party providers—to offer you products and service plans (open access). It is therefore possible that you may be contacted by other companies, such as 1&1 Telecom GmbH, regarding fiber-optic expansion, even if your address does not appear in their coverage area according to the list above.

Telecommunications companies do not lay the fiber-optic cables themselves; instead, they contract construction and engineering firms to do so. Construction sites within urban areas may therefore also be identified by the name of the respective construction company. Site visits to coordinate the installation on your property or within your building may also be conducted by construction or engineering firms on behalf of the telecommunications companies.
