Splice free to deliver optimum test results.

OTDR Launch Boxes and Portable Launch Cords provide a calibrated span of optical fiber to evaluate near-end connectors and anomalies in network fiber systems. The assembly is placed between the system under test and an OTDR (Optical Time Domain Reflectometer) to improve the OTDR’s ability to identify passive system components and abnormalities during system qualification and troubleshooting.

Full-Featured Design Offers Maximum Protection & Versatility

Our full-featured Launch Box design stores the cable assembly in a lightweight, rugged transit case that protects the sensitive optical components against harsh outside environments. For long haul testing, Fiber Connections’ Launch Boxes are capable of holding single-mode or multimode fiber lengths up to 25km. The Portable Launch Cord is a portable, lightweight unit capable of holding up to 500mtrs. Custom lengths and various connector styles are available.

Get the Whole Picture

An OTDR’s inability to “see” near-end fiber optic connectors at the patch panel, and often the first few meters of fiber, severely reduces the effectiveness of testing efforts. This is due to the relatively slow recovery time of laser pulses reflecting off the OTDR bulkhead connector and subsequently being displayed on the monitor. Using a properly calibrated length of fiber with high quality components can solve the problem.

The Problem with Fusion Splicing

Unlike most OTDR launch boxes, our cords are directly connectorized to provide a continuous, high-quality link for OTDR testing. A fused pigtail within several meters of each connector tip cannot be independently identified on the OTDR and increases the apparent loss of each connector. This reduces the near-end measurement accuracy of the OTDR. Fiber Connections’ Launch Boxes and Portable Launch Cords are splice free to deliver optimum test results.
