A multi-hop free space optical link based on all-optical relays is presented.All-optical relays are either composed of simple optical amplifiers or optical regenerators.It has been CE Health shown that after a certain number of hops, the amplifier based relay cannot extend the range of the free space optical link.

Therefore, we have investigated the use of a self phase modulation based regenerator as a substitute for simple amplifier based relay.By employing the regenerative relay, a 10 Gbps optical signal having pulse width of 7 ps is transmitted over a distance of 8 km of free space optical link.The free space optical link is modeled on the basis of Gamma-Gamma channel model in the strong turbulence regime.

The performance of the link is observed on the basis of bit error rate analysis.It has been shown LEAVE-IN MOUSSE that under strong turbulence and accumulation of amplifier noise, the range of the link can only be extended by employing an optical regenerator.
