Bend limiter

摘要

A bend limiter configured to interface with an elongated optical fiber to limit bending of the optical fiber. The bend limiter includes an elongated spring having a spirally extending coil that at least partially defines an inner bore. The inner bore is adapted to accommodate the optical fiber such that the spirally extending coil extends coaxially around the optical fiber. The elongated spring provides bending resistance that limits the bending of the optical fiber. In one aspect, the outer diameter of the bend limiter (formed from an elongated spring) can be constructed much smaller than current bend limiter outer diameters for optical devices.
