Measured loss for the LP11 mode in a dual-mode fiber subjected to a uniform bend shows a strong dependence on the orientation of the mode-field pattern relative to the plane of the fiber bend. Wavelength and bend-radius dependence of the loss indicates that operation within ~40 nm of cutoff is feasible in dispersion compensators based on dual-mode fibers operated in the LP11 spatial mode near cutoff.

Although the LP mode designations in this reference apply to circular fibers only, we make use of them here for our elliptical fiber since the mode patterns are nearly identical to those in the circular case, in spite of the fact that LP11 modes are no longer degenerate.
