Abstract 

The UOWC system employing 450 nm blue laser with 1.25 Gbps in the 6-meter distance was measured under the various environmental parameters. The transmission channel was improved using the slight reflected angle. This condition can compensate for the attenuation caused by the scattering and absorption in the transmission channel. The UOWC transmission system experiment was carried out under several environmental parameters, including depth of surface turbulence, temperature, and turbidity. The deeper laser beam from the water surface provides lower BER of 4.116 x 10-8 with the received optical power at -15.52 dBm. The UOWC system offers a wider eye diagram at room temperature of 25°C and 10°C.The 450 nm exhibits better signal quality and optical power loss in tap water, while the 520 nm holds better optical signal loss in turbid water.

Instructions: 

First of all, this data set is includes the measurement in underwater optical wireless communication (UOWC).

The measurement is consist of environmental factors such as water turbulence, temperature gradient, and water turbidity.

Then, We measured the experimental works as shown in the UOWC main scheme, then analyze the data using origin software.

The data includes the bit error rate (BER), optical power meter measurement in different environmental factors.

After all, the graph was created to analyze the impact of environmental factor in terms of BER and optical power.
