The NF-904-10MW Visual Fault Locator (VFL) uses a DFB-LD as its light-emitting component. The indicator is driven by a constant current source to emit a stable red laser. This tool can be used to inspect for fiber faults when connected to an optical interface and inserted into single-mode or multi-mode optical fibers.
It is an indispensable tool for fiber project construction, network maintenance, and the manufacturing and research of optical components. The detector can easily and accurately detect and locate fiber breaks, poor connections, bends, or cracks. It emits a bright 650nm red light for tracing, and any breaks or faults in the fiber will refract this light, creating a bright glow around the faulty area.
It can test both single-mode and multi-mode cables with its standard 2.5 mm fiber optic connectors. The device features an impact and dust-proof design for the laser head and a durable casing to efficiently prevent damage. The body is made from a durable aluminum alloy for long-term use. It also has a low-loss, replaceable internal ceramic insert and a lightweight, pen-type design that makes it easy to carry.
