The Infrared Fiber Tester Pro is primarily used for checking the signal output power of the optical communication equipment in fiber optical networks. It measures the average power of a continuous light beam which emits from the equipment or other optic sources. It measures power in both 850nm/1300nm (multi–mode) and 1310nm/1550nm (single–mode) respectively.

The Infrared Fiber Tester Pro consists of a solid state InGas photo diode, signal power measurement circuitry, and a 2 digit LED display. Users just connect a fiber cable between the transmission port of the equipment and the universal interface on the Infrared Fiber Tester Pro, or they can connect to other light source. The product will show the exact amount of the received power value (in–dBm). The test ranges are 30dBm to –15dBm in wavelength 850nm/1300nm and –30dBm to –6Bm in wavelength 1310nm/1550nm.

The universal connector can be used for all the most common fiber interfaces such as ST/SC/FC/FDDA and it also suitable to test both single–mode and multi–mode cables. With an optional 2.5mm to 1.25mm adapter, users can even test for 1.25 fiber cables.

The Infrared Fiber Tester Pro can operate in coordination with Hobbes’s optisource or most other fiber LD light source to  be a complete fiber measurement kit.
