Abstract
A dual-core optical fiber include a first waveguide comprising a first core longitudinal centreline and a second waveguide comprising a second core longitudinal centreline. The first and second waveguides extend through a common cladding through comprising a longitudinal centerline and an outer radius Rthat is less than or equal to 45 μm. The first core longitudinal centerline and the second core longitudinal centerline are separated from one another by a waveguide-to-waveguide separation distance that is greater than or equal to 30 μm. A cross-talk between the first and second waveguides is less than or equal to −40 dB at 1310 nm, as measured over a length of 100 km of the dual-core optical fiber.
