Abstract

We demonstrate a transmission of 4×10 Gb/s WDM channels over 1.2 km of free space in 1.55-µm band. The transmitted beam is coupled into a single-mode fiber through a fiber-pigtailed collimator, which enables the use of standard 100-GHz channel spacing and an optical preamplifier at the receiver. All the received channels have Q values higher than 6.
