Visible light wavelength division multiplexing (VWDM) experiment was performed using polymer opticalfiber (POF). Lights of two different wavelengths (650 and 530 nm) were sent to a single POF. Red light(650 nm) was used for 100-Mb/s full duplex IP data transmission and green light (530 nm) was used forvoice signal transmission. Light sources are light-emitting diodes (LEDs). A POF coupler (splitter) andthe prisms were employed as multiplexer and demultiplexer, respectively. The channel isolation and insertloss were measured, which are 20.5 and 17.65 dB for 650-nm channel respectively, and 19.16 and 20.55 dBfor 530 nm one respectively.
