Fiber Launch Box

Basics of an OTDR Launch Box

An Optical Time Domain Reflectometer (OTDR) is a mandatory fiber optic testing tool that uses light backscattering technologies to analyze optical fiber performance. An OTDR can test the light loss and locate the breaks, splices, and connectors in a fiber-optic network. However, an OTDR has a “Dead Zone” which can affect the test results. To overcome the limitation of this OTDR dead zone, an OTDR Launch Box is used.

Launch boxes aid in the testing of a fiber optic cable when using an OTDR. Launch boxes are used with OTDRs to help minimize the effects of the OTDR’s launch pulse on measurement uncertainty. They are used for Installation/Testing, Training, and Calibration. They can also be called a Pulse Suppressor or Delay Line.

All of iFiber Optix’s Launch Boxes are terminated with low-loss connectors for exceptional accuracy and performance. Launch boxes are available within 100, 80, 60, and 20 kilometers of fiber and different connector configurations.
