Overview
The EXFO LFD-202 is an essential field tool designed for identifying optical signals within fiber optic cables without disrupting network traffic. This live fiber detector allows technicians to detect traffic presence, traffic direction, and specific optical tones, while also measuring fiber power levels.
Engineered for high-performance field testing, the LFD-202 is compatible with a wide range of fiber types including coated, jacketed, and ribbon fibers. Its robust design is well-suited for demanding installation and maintenance environments where accuracy and signal integrity are critical for network uptime.
