FIBER IDENTIFIER ST820B

The ST820B is an ideal tool for installing, organizing, or reusing fibers, and for determining whether a fiber is in use or for distinguishing between fibers. When the ST820B's probe is placed on an optical fiber, the device indicates whether there is traffic or modulated light on the fiber and in which direction the light is traveling. The device detects common modulations (270Hz, 1 kHz, and 2 kHz) across the 800 nm to 1700 nm wavelength range. In addition to indicating the direction of traffic, the device also displays the relative optical power level on a digital readout. The ST820B features a durable metal housing and comes standard with probe tips for various fiber sizes: Ø0.25 mm, Ø0.9 mm, Ø2.0 mm, and Ø3.0 mm. The test adapter and the fiber under test can be protected from ambient light using the standard rubber shield, which enhances test reliability. The standard ST820B configuration includes the ST820B traffic detector, adapters for 0.25 mm, 0.9 mm, 2 mm, and 3 mm fibers, a light shield (rubber), two AAA batteries, a user manual, and a protective case.
