| Term (EN) | cut-off wavelength (of a singlemode optical fibre) | 
|---|
| Definition (EN) | In a singlemode fibre, it is that wavelength in vacuum greater than which the second order LP11 mode ceases to propagate.
Note. — The measured value in general depends upon the measurement conditions and in particular the sample length. |
