Disc Type OTDR Launch cable Box for Fiber Optic Dead Zone Elimination

This compact, rugged, and lightweight Fiber Optic OTDR Launch Cable Box is designed to remove OTDR dead zones, allowing precise measurement of insertion loss and reflectance at both near-end and far-end connections. Available in standard lengths of 100m, 300m, 500m, 1km, and 2km, it supports single-mode (9/125μm) and multi-mode (50/125μm, 62.5/125μm) fiber types. The coiled design fits easily into OTDR cases or kits, and the special adapter storage bin keeps connectors organized. Use it as a launch cable, receive cable, or both to generate a complete baseline trace for short, medium, or long-distance fiber networks.
