The tariff classification of Optical Loss Test Set

The tariff classification of the CMA 50 Loss Test Set Dear Ms. Stilwell:In your letter dated July 7, 2005, you requested a tariff classification ruling on the CMA 50 Loss Test Set. Descriptive literature on the CMA 50 Loss Test Set was submitted with the ruling request.The CMA 50 Loss Test Set is a fiber optic measurement device that measures quantities of light as carried within fiber optics, and uses that measurement information to ascertain certain optical characteristics of the fiber. Two CMA 50’s are used during the test, one at each end of the optical fiber being tested. The first unit sources a light signal of known wavelength into the fiber. The second unit measures the received light. The CMA 50 has two, three or four fixed wavelength sources, depending upon the configuration of the unit. It is used as a field instrument by telecom, datacom, and cable television installers and technicians and by repairmen during the installation and maintenance of optical communication fi
