Properties and Potential Applications of a Bend Optimised Singlemode Optical Fibre

摘要

A G.652.D compliant single-mode fibre has been developed which has superior macrobending performance compared to legacy fibres in this category. The macrobending performance of this fibre is demonstrated at tighter bending diameters down to 20mm and shown to exceed the performance of legacy G.652.D fibre by several times. It is further demonstrated that the tighter fibre bending diameter enabled by the macrobending properties of this fibre is still sufficiently large as to ensure against premature mechanical failure. The fibre is shown to be compatible with legacy G.652.D fibres in studies of fusion splicing performance. Several applications are suggested for the use of this fibre type to bring economic value, particularly to the access network. Allowing tighter bends in the optical fibre can enable smaller fibre management hardware such as optical distribution frames and wall units. Tight buffered patch cords may be designed for installation in more restricted spaces. Improved portability of OTDR injection fibres is enabled.
