Measuring the distance to open circuit with an optical power meter
Set the power meter to the transceiver's operating wavelength and attach a short, clean jumper from the transceiver output to the meter. Record the displayed Tx power and compare directly to the transceiver datasheet (don't guess. A fiber-optic power meter is a quantitative measurement instrument, not a diagnostic tool by itself. Its sole function is to measure the optical power level arriving at a specific point in a fiber link, expressed in dBm or mW. Consistent procedures ensure accuracy. Verify light travels from transmitter to receiver. Proper cleaning and. An OLTS provides the most accurate insertion loss measurement on a link by using a light source on one end and a power meter at the other to measure precisely how much light is coming out at the opposite end. In practice you'll use two complementary tools — an optical power.
