1. An optical fibre cable including at least one optical fibre assembly, the at least one optical fibre assembly comprising:
a hollow core, antiresonant optical waveguide comprising a hollow core surrounded by a ring of longitudinally extending capillaries providing an inner cladding surrounded by an outer cladding, the hollow core antiresonant optical waveguide configured to guide light along the hollow core by an antiresonant effect;
a diagnostic solid core optical waveguide comprising a solid core surrounded by a cladding, and extending substantially parallel to the hollow core optical waveguide; and
a jacket surrounding both the hollow core optical waveguide and the solid core optical waveguide and forming a common mechanical environment for the hollow core optical waveguide and the solid core optical waveguide.
