The problem of determining the energy budget and the maximum data rate for underwater wireless optical communication channel on deep depth is considered. The aim of this work is the estimation underwater wireless optical channel energy budget and the maximum data rate on deep depth. The article has shown that at a depth of more than 1000 m the water state is preserved, the salinity is kept at 34,5 ... 35 ‰, and the temperature is 3 ... 5 ° C. The result of water properties stability is a small spread of the parameters of underwater wireless optical communication channel at the depth of more than 1000 m. The laser beam divergence by the particles suspension effects is calculated. The calculations results obtained have shown that at the distance of 100 meters the maximum data rate is from 2 Mbit / s to 1,5 Gbit / s and the diameter of suspension particles has the greatest influence on data rate.

Key words: underwater optical communication channel, optical communication, wireless optical channel, mathematical model, underwater communication systems.
