Another option exists for fiber. The bundles could be blown through tubing system on the viscous air drag up to a distance of 2Km per compressor. Compressors in series are supported allowing longer runs. And the system is bidirectional. By supporting long runs with minimized tension and without splices, the db budget is protected and the lifecycle costs associated with deterioration of splices is avoided.
