In-house networks using multimode polymer optical fiber for broadband wireless services

A novel system concept is presented to transport microwave signals over an in-house multimode graded-index polymer optical fiber network in order to feed the radio access points in high-capacity wireless LANs. By employing optical frequency multiplying the network's intrinsically limited bandwidth is overcome. The feasibility of this concept to carry data at several hundreds of Mbit/s speed for various microwave signal formats at carrier frequencies in the tens of GHz range is shown. The concept enables cost-effective system implementation and easy upgrading by offering data signal transparency. It can be readily integrated with other system technologies such as wired Gigabit Ethernet in a single multi-service in-house polymer optical fiber network.
