Kit power meter dan light source yang mudah dipakai untuk mengukur loss serat di jaringan gedung dan kampus. Power meternya membaca enam panjang gelombang dengan rentang 70 dB sampai +10 dBm, bisa menguji dua panjang gelombang sekaligus, dan menyimpan 1.000 hasil. CheckActive memberi tahu jika serat sedang aktif.
