4.2 Construction of type 'B' single core cable The cable shall consist of a single, step-index, multimode, all silica fibre (pure silica core with sufficiently high OH content to meet nuclear radiation hardening requirements) and suitably doped silica cladding which is protected by a primary coating. The cable shall have a tight buffer, all dielectric (non-conducting) construction, with strength members and outer sheath, and have an operating temperature range of − 60 °C to 150 °C. The cable shall comprise an outer sheath, strength member, inner sheath, buffer, and fibre, which is protected by a primary coating.
