Does every jumper have its own “identity card” and performance data?

In industrial-grade optical fiber communication and fiber optic sensing engineering, qualified Fiber Optic Patch Cords and fiber optic sensors are typically equipped with a dedicated **Factory Test Report** , and each patch cord is associated with its physical product through a unique identification number (Product Serial Number / SN code), establishing a mapping relationship between the physical product and its test data (the so-called “ID card”).

### I. What is a “Factory Test Report” and the Function of its “ID Card”

A **Factory Test Report** is the authoritative quality certificate for fiber optic patch cords or sensors, generated after completion of assembly, polishing, and encapsulation processes. It documents the core optical and physical performance indicators as determined by professional instruments and equipment.
