Integrated environmental control and management system for free-space optical communication systems
First Claim
1. A method of managing a free-space optical network, comprising the steps of:
- directing network data traffic over one or more free-space optical links in the free-space optical network;
monitoring one or more environmental conditions in a vicinity of at least one of the one or more free-space optical links; and
routing the network data traffic through an non-wireless alternate communication path in response to data obtained from the step of monitoring one or more environmental conditions in a vicinity of at least one of the one or more free-space optical links;
wherein the step of monitoring one or more environmental conditions comprises the step of collecting data indicative of at least one of the one or more environmental conditions with an instrument located in the vicinity of the at least one of the one or more free-space optical links;
wherein the step of monitoring one or more environmental conditions further comprises the step of;
sending an alarm over the free-space optical network in response to the data indicative of at least one of the one or more environmental conditions.

Abstract
A method of managing a free-space optical network includes monitoring environmental and weather conditions in the vicinity of one or more free-space optical links in the network. Data is gathered by environmental condition instruments, such as visibility meters, and is used to assess whether atmospheric conditions have deteriorated to the point where operation of one or more free-space links might be in jeopardy. If data from an environmental condition instrument falls below a predetermined level, network data traffic is routed over an alternate communication path, which may include radio frequency (RF) paths, fiber optic cables, wire cables, or other free-space links.
