VFL 5mW

NF-904 Visual Fault Locator uses the DFB-LD as the emitting component. Driven by constant current source, the indicator can emit stable red laser. The product can be used to inspect fiber failure when they connect with optical interface and be inserted into single mode or multi mode optical fiber. It is indispensable tool in fiber project constructing, fiber net-work maintaining, optical component manufacture and research.
