FL-3327 Insertion Loss & Return Loss Tester for SM/MM Fiber

The FL-3327 Insertion Loss & Return Loss Tester for SM/MM Fiber is a high-performance fiber optic tester designed for precise Insertion Loss (IL) and Return Loss (RL) measurements on singlemode fiber or multimode fibers. Featuring a built-in high-stability light source and a large color LCD, it allows intuitive operation and real-time test feedback. Dual-wavelength IL & RL measurements are performed simultaneously, with user-defined threshold settings and automatic red warning indicators for failed results. The device supports multiple fiber interface types and includes a built-in VFL (Visual Fault Locator) for rapid jumper identification. An optional 850nm wavelength module enables multimode patch cord loss testing, making it ideal for lab, manufacturing, and field applications.
