2 $\times$ 80 Gbit/s DWDM Bidirectional Wavelength Reuse Optical Wireless Transmission [PDF]

open access: yesIEEE Photonics Journal, 2013
We demonstrate a practical 2×80 Gbit/s dense wavelength division multiplexing (DWDM) bidirectional short-range optical wireless link. The measured power penalties for the bidirectional transmission are less than 0.8 and 0.2 dB compared to the back-
