This report updates Naval Ocean Systems Center TR 1185, 104-km Unrepeatered Bidirectional Fiber-Optic Demonstration Link, May 1987. Provided are discussions on improvements made to the original demonstration system. These include enhanced receiver sensitivities, increased laser-transmitter optical power outputs, refined operation of the PFM and Manchester encoding subsystems, and reduced splice losses. Also discussed is the emerging technology of fiber amplifiers that promise to significantly extend the repeaterless distance beyond the present range.
