The Specialized Products SPC958 Test Kit combines the Jonard Tools® FPM-50A optical power meter and FLS-55 SM/MM light source for measuring absolute optical power and relative power loss in fiber optic cables. The light source provides stable 850/1300 nm or 1310/1550 nm wavelengths for multimode or single mode fiber measurements. Adapters directly connect to UPC/PC FC, SC, and LC fiber connectors. The unit features 4 different modulation outputs (CW, 270 Hz, 1 kHz, 2 kHz). The intelligent OPM measures from -50 to +26 dBm at 850, 980, 1300, 1310, 1490, 1550, 1625 and 1650nm wavelengths. It allows manual calibration. The included VFL-150 kit offers a laser-powered 650nm visual fault locator for fiber tracing and routing, testing continuity, locating fiber optic cables breakpoints and poor connections.

The SPC958 test kit comes in a durable blow molded case (12-3/8"x8-7/8"x2-7/8"), filled with foam to protect the equipment.
