| 摘要 |
The invention relates to an optical terminating set for time-modulated optical transmission signals. The problem of crosstalk attenuation of the terminating set specific for these signals is solved by concentrically coupling a first glass fibre (1) to a second glass fibre (2) with a larger core diameter in the coupling area. The signal emerging in the difference area from the glass fibre with larger core diameter is supplied to a detector (4) either via a mirror (3) or directly. |
