Tektronix TFC200 Handheld Optical Power Meter

The Tektronix TFC200 is a handheld optical power meter for measuring optical power levels across fiber optic networks. It performs absolute power measurements, link loss analysis, threshold testing, and real-time power level monitoring in telecommunications, CATV, and LAN environments. The instrument supports both singlemode and multimode fibers up to 200 µm core diameter with 0.3 NA, delivering ±3% accuracy (±0.1 dB) across a dynamic range of +10 dBm to -70 dBm.

A large backlit LCD display ensures readability in direct sunlight and low-light conditions, while intuitive controls enable field operations without extensive training.
