FOD 5516 Series

The FOD5516 Clip-on Coupler is designed to inject and detect light signals in Single mode optical fiber. The FOD5516 is used when there is no access to one or both fiber ends such as in splice enclosures. The most common applications are with Optical Talks Sets and injecting a test tone to trace fibers with an Optical Fiber Identifier along the network. The FOD5516 does not affect the mechanical integrity of the fiber.
