A method may include bending a first optical fiber of a plurality of optical fibers; measuring light leaked from the first optical fiber with a photo detector; robotically moving the photo detector to a second optical fiber of the plurality of optical fibers; bending the second optical fiber; and measuring light leaked from the second other optical fiber with the photo detector. The first clamp is coupled to the body. In the co-compilation approach, a first schema description references a second schema description, and the subset includes a set of entities from the second schema description that are used by the first schema description. In the second channel, a room air is taken through the second inlet duct and discharged to outdoors through the second outlet duct.
