The FiberTEK IV-MM LED & SM Laser Kit is a versatile field test solution that combines both multimode LED and single-mode laser capabilities to cover a wide range of fiber certification tasks. The kit includes two multimode FiberTEK IV LED modules for multimode link verification and two single-mode FiberTEK IV laser modules for single-mode loss testing and loopback referencing. Interchangeable SC, FC, and ST adaptors (two of each) let technicians connect quickly to the most common fiber terminations, while supplied SC–SC patch cords and a concise quick reference guide simplify correct setup and referencing procedures to meet ISO/IEC 14763-3 requirements.

Built for daily use on job sites, the kit is shipped in a lockable, semi-rigid carrying case that protects instruments and accessories while keeping everything organized for fast deployment. Designed to work seamlessly with LanTEK IV certifiers, the combined MM LED and SM laser modules reduce the need for multiple tool sets, speed up turnover time, and help teams deliver documented, standards-compliant results whether they’re certifying new installations or troubleshooting existing networks.
