Average power monitor accuracy
 
Single-mode
± 5% ± 200 nW ± connector uncertainty
Multimode (characteristic)
± 10% ± 200 nW ± connector uncertainty
Due to variations in mode-filling conditions, the measured power in multimode fiber will vary more than the
measured power in single-mode fiber. For users needing the most accurate power measurements, use an
optical power meter for multimode power measurements
