ST820B optical fiber identifier is an essential instrument for the installation and maintenance of optical fibers. With 1310nm or 1550nm wave length ST820B indicates the direction of the transmitted signals. It can easily recognize SM fibers and find and locate a specific fiber without interference to the transmission. ST820B has a rugged construction and several interchangeable adapter clamps for different fiber sizes are available: Ø0.25mm, Ø0.9mm, Ø2.0mm and Ø3.0mm.
