2.4-km free-space optical communication 1550-nm transmission link operating at 2.5 Gb/s: experimental results

We describe a terrestrial free-space optical data link operating at 2.5 Gb/s using currently available 1.5 micrometers telecommunications electro-optic transmission components. The 2.4 km free-space optical data-link is characterized by bit-error-rate system performance. The optical link utilizes a 1.5 micrometers DFB laser device which is directly modulated and operating within the erbium amplification band.
