VCSEL-based Single-mode and Multimode Fiber Star/Tree Distribution Network for Millimeter-wave Wireless Systems

A cost-effective VCSEL-based star/tree radio over fiber architecture for indoor millimeter-wave systems is presented. The indoor pico-cells can be located many km from a Central Office, with the longer distance distribution performed using single-mode fiber and the in-building distribution using multimode fiber. The feasibility of the system is verified through experimental results demonstrating emulated signal transmission (QPSK, 16-QAM, 64-QAM at 6MSps) over the required single-mode and multimode fiber components with good EVM performance
