The EXFO TKS-CAL Optical Calibration Kit enables in-house verification and calibration of fiber-optic test instruments without external service delays. This modular, expandable platform calibrates optical power meters, light sources, attenuators, and OTDRs while maintaining metrological traceability to NIST and METAS primary reference standards. Users perform manual calibrations following ISO-17025 procedures, reducing downtime and associated shipping costs. The kit includes an Excel-based calibration certificate template and detailed step-by-step instruction guides.
## Technical Specifications
