CSM1 Contractor Series Optical Power Meter
The Noyes CSM1 from AFL Telecommunications is a palm-sized, cost-effective optical
power meter designed for measuring optical power in Premises, Telco, or Broadband fiber
optic networks and for performing insertion loss measurements on multimode or single-
mode fiber optic links. Weighing only 0.4 lb, this power meter is ideal for field use.
The CSM1 stores optical references for each calibrated wavelength and features multiple
test Tone detection for fiber identification. A large LCD display with backlight shows
measured power [dBm or µW] or insertion loss [dB], calibrated wavelengths [nm], tone
frequency [Hz], and indicates a low battery condition.
The CSM1 optical input port accepts a variety of Noyes thread-on style adapter caps
(ordered separately) to meet a wide range of testing requirements. One adapter cap,
2.5mm Universal, is included.
Being powered by two AA alkaline, the CSM1 offers a five-minute auto-off feature and over
300 hours of operation with backlight off.
The CSM1 is fully N.I.S.T. traceable.
