The Infrared Fiber Tester Pro SM is used to check signal output power from optical network devices. It measures the average power of a continuous light beam which emits from the equipment or other optic sources. The Infrared Fiber Tester Pro SM measures power in 1310nm/1550nm Single-Mode range.

The Infrared Fiber Tester Pro SM consists of a solid state InGas photo diode, signal power measurement circuitry and 2 digit LED display. Simply connect a fiber cable between the transmission port of the equipment and the universal interface on the Infrared Fiber Tester Pro SM. The tester will show the exact amount of the received power value in dBm. The test ranges are 30dBm~ -15dBm in wavelength.
