Overview
The FiberXP FR-STULCUS21000M is a single mode fiber optic launch cable designed specifically for use with Optical Time-Domain Reflectometers (OTDRs). By providing a lead-in length of fiber, it allows the OTDR to overcome the initial dead zone, ensuring that the near-end connector of the cable under test can be accurately characterized.
This unit features 1000 meters of high-quality Corning single mode 9µm fiber configured in a compact, portable ring design. It includes 1-meter pigtails with ST to LC connectors and is housed in a durable pouch, making it well-suited for field testing environments where portability and equipment protection are required.
