Two methods have been proposed to equally couple the optical power of a single mode fiber (SMF) into the two cores of an embedded-dual-core hollow optical fiber (EDCHOF). The loss of two splicing ...

This paper demonstrates a fiber-optic time transfer over a 6000 km noncalibrated fiber link using proposed single-fiber bidirectional-transmission unidirectional optical amplifiers (SFBT-UOAs). The ...
