The TFS-FS1™ Optical Leakage Detector is designed to locate energy leaks in fiber optic systems and to identify fibers over long distances.
The TFS-FS1™ Optical Leakage Detector is designed to locate energy leaks in fiber optic systems due to splice loss, connector loss, breakage, or bending and to identify fibers over long distances.
This optical leakage detector is the most sensitive fiber light finding instruments on the market today. By simply sweeping over a fiber, the leak detector will give an audio and visual indication whenever it encounters a light loss point. Often performing the same function as a visible laser source, this product is used in OTDR dead zone areas or splice enclosures where exact pinpointing of a fault is critical.
The major advantage of the TFS-FS1 over a visible laser however is that it can "see" cable faults in bright room light and in many blue, green, and black coated fibers. Find light reflected from connectors mated in bulkhead adapters and even through some dust caps. Locate fibers at distances up to 186 miles (300 Km), not just a few miles.

The TFS-F1280™ Filter Kit is a is wide band IR filter (1280-1620 nm) designed to work with the TFS-FS1™ Optical Leakage Detector to locate energy leaks in fiberoptic systems due to splice loss, connector loss, breakage, or bending and to identify fibers over long distances.

The TFS-F1310™ Filter Kit is a is narrow band IR filter (1310 nm) designed to work with the TFS-FS1™ Optical Leakage Detector to locate energy leaks in fiberoptic systems due to splice loss, connector loss, breakage, or bending and to identify fibers over long distances.
The TFS-F1490™ Filter Kit is a is narrow band IR filter (1490 nm) designed to work with the TFS-FS1™ Optical Leakage Detector to locate energy leaks in fiberoptic systems due to splice loss, connector loss, breakage, or bending and to identify fibers over long distances.
The TFS-F1550™ Filter Kit is a is narrow band IR filter (1550 nm) designed to work with the TFS-FS1™ Optical Leakage Detector to locate energy leaks in fiberoptic systems due to splice loss, connector loss, breakage, or bending and to identify fibers over long distances.
The TFS-TSA™ Aerial Lens and Scope Kit is designed to work with the TFS-FS1™ Optical Leakage Detector to identify aerial fiber breaks from the ground. The complete kit includes the aerial lens, red-dot scope, and narrow band IR filter (1550 nm).

The TFS-290™ Series Optical Tracer Sources, when used with TFS-FS1™ Optical Leakage Detector, allow technicians to perform leak detection and long distance optical tracing.

The TFS-FS1K500™ Series Optical Leakage Detector Kits are designed to locate energy leaks in fiberoptic systems and to identify fibers over long distances.
