Outage performance analysis of all-optical amplify-and-forward relaying over dual-hop optical inter-satellite link

In this paper, outage performance of dual-hop optical inter-satellite link (OISL) employing all-optical amplify-and-forward (AOAF) relaying is analyzed. Take into account the combined source-to-relay (S-R) and relay-to-destination (R-D) channel attenuation induced by geometric spread and pointing error within outer space environment, a series of closed-form expressions for outage performance are derived. Numerical results indicate that the performance of AOAF relaying dual-hop systems is low-complexity and has better performance than that of the non-relay systems under the same total power consumption.
