Well, a prism makes sense if you're sending multiple signals in the same fiber, and want to separate and combine the signals at the ends. The fiber connection I'm renting has two wavelengths on the same fiber.
The installation guys actually used a device to bend individual fibers during installation, to see which ones were carrying signals. Here's a similar device: http://www.tuolima.com/optical-tool-series/test-equipment/optical-fiber-identifier.html http://www.tuolima.com/optical-tool-series/test-equipment/op...
- wyck 13y agoI think you can also use a prism to just split 1 fiber into 2 or more, much like a mirror, similar to how some laser systems work. So in essence the original beam goes on it's merry way unaffected and the duplicate(s) goes into a black box. Though I know very little about this subject I would assume the splitter has to be exact and completely lossless. I also think there are tools to measure any interference. For example a device like this is used to reflect fibers: http://www.ozoptics.com/ALLNEW_PDF/DTS0095.pdf http://www.ozoptics.com/ALLNEW_PDF/DTS0095.pdf
