We Connect and Protect

Organizations which manufacture, install, and provide support services related to fiber optic sensing systems and equipment may apply for membership in the Fiber Optic Sensing Association (FOSA).  Annual dues are $10,000 (U.S.) per calendar year.  On December 1, new members who have paid dues for the following year can participate in the December FOSA meeting and participate in board and officer elections.
