The method can further include displaying the wavelength of the light and a detected power level.

Abstract: Optical fiber adapters and connectors are provided. An optical fiber adapter includes an adapter body, the adapter body extending along a longitudinal axis between a first end and a second end and comprising a first adapter portion which includes the first end and a second adapter portion which includes the second end. Each of the first adapter portion and the second adapter portion is one of a male adapter portion or a female adapter portion. The optical fiber adapter further includes a ferrule disposed within the adapter body, the ferrule extending along the longitudinal axis between a first end and a second end, and a thin-film filter provided on one of the first end or the second end of the ferrule, wherein the thin-film filter limits the wavelengths of light transmitted therethrough to within a predetermined wavelength range.

Abstract: A steering column arrangement for a motor vehicle may include a guide part for rotatably mounting a steering shaft about a longitudinal axis, a guide box that is mountable on the motor vehicle and in which the guide part is arranged displaceably along the longitudinal axis, and a clamping system that is for locking the guide part in the guide box and that is switchable between a locked state where the guide part is secured relative to the guide box and a released state where the guide part is displaceable relative to the guide box in a direction of the longitudinal axis, and first and second contact surfaces disposed between the guide box and the guide part. In the released state the first contact surface is in first frictional contact with a surface of the guide part that opposes a displacement of the guide part along the longitudinal axis relative to the guide box.
