We evaluate the transmission of digital signal modulated on radio-frequency subcarriers through multimode fiber (MMF) by using low-cost 850-nm vertical-cavity surface-emitting lasers and 50-μm/62.5-μm-core matched receptacle photodiodes. Several mobile telecommunication and wireless local area network standards have been transmitted through standard (500 MHz·km) and high bandwidth (1500 and 2000 MHz·km) Corning Infinicor SXi and SX+ MMF under different lengths (100, 300, and 600 m). Characterization has been carried out to measure error vector magnitude (EVM) variation as a function of fiber type and length. EVM minor to IEEE and ETSI requirements are obtained for all standards being tested such as IEEE 802.11 g with 1.8% root-mean-square for 300 m of 50-μm-core standard MMF at 850 nm.
