Hobbes, 257836DK3, SMARTFiber and OPTISource LD Light Source for Wavelength (850/1300/1310/1550) Kit Interchangeable FC, SC, ST Connector (with Carrying Case)SMARTFiber and OPTISource 850/1300/1310/1550 Kit is an essential and efficient fiber testing equipment kit that includes a Power Meter and Optical Light Source. The SMARTFiber is a four wavelength (850nm, 1300nm, 1310nm, 1550nm) Fiber Optic Power Meter used for measuring the optical power from fiber optic cabling systems. It includes interchangeable connectors for testing FC, ST, and SC type interface. It utilizes InGaAs photodiode for greater sensitivity and temperature stability. It is suitable for testing single-mode and multimode fiber cables. SMARTFiber is capable of simultaneously receiving modulated signals at 270Hz, 1KHz, 2KHz for identifying and continuity testing of fiber cables. When using with the OPTISource 850/1300/1310/1550 high-stability LD light source, this kit ensures signal attenuation, certification, fault detection, breaks, and bends of multimode fiber cables. It is an ideal kit designed for network professionals during installation and maintenance to minimizing interruptions and downtime of optical network cabling systems.
