TM301 Optical Fiber Identifier (Live Fiber Detector) is an essential instrument for the installation and maintenance of optical fiber projects. It can easily detect any spot of SM fiber cables. Through inserting a 1310 or 1550 modulated signal into the fiber, it is used to indicate the direction of the transmitting signals, find and locate the specific fiber without interrupting the normal work during the installation, cabling and maintenance.
