The TOP130, 140 and 150 optical test products test multimode cables in local-area or wide-area networks or singlemode cable used by telephone companies and cable-TV operators. The TOP200 power meter makes basic optical power measurements in either decibels or decibels relative to milliwatts, calibrated at 850 nanometers, 1300 nm and l550 nm.
