Key Features
Integrated Loopback + Attenuation – Combines signal looping and power reduction in a single duplexed module, eliminating the need for additional components and equipment
Multimode Compatibility – Optimized for OM1 (62.5/125µm), OM2, OM3, and OM4 (50/125µm) multimode fibers
Male-to-Male LC/UPC Configuration – LC/UPC connectors on both ends for direct connection to LC ports on equipment or patch panels
Fixed Attenuation Values – Available in 1–25dB range to suit diverse testing and power management requirements
High-Precision Alignment – Zirconia ceramic ferrule sleeves ensure accurate fiber core alignment and consistent performance
Low Insertion Loss – ≤0.3dB ensures minimal impact on the test signal itself
Durable Construction – Rugged protective housing with dust caps to prevent contamination when not in use
