The professional-grade Wirepath test kit gives integrators the advanced tools they need for optical link testing, plus the software to comb through and store data records. The optical light meter and light source units test both multimode and single mode fibers at four wavelengths with a range of 70db, measuring optical power loss on all installed fiber. Plus, new software for PCs allows for fast testing and easy reporting on data output. Kit includes adapters to test SC, LC, and FC terminated cables; both termination test units and included cables and adapters are contained in a rugged hard-shell case that organizes and protects all your essential equipment.
