CKM-2 Contractor Series Multimode Test Kit with Set Reference

NOYES CKM-2 Contractor Series Test Kit combines the CSM1-2 optical power meter and CSS1-MM Dual LED light source to provide a cost-effective test kit designed for performing insertion loss measurements on multimode as well as single-mode fiber optic links.

CSS1-MM source features Dual output, 850 /1300 nm LED, from a single output port. CSS1-MM models offer 2 modes of operation, continuous wave (CW) and user selectable modulated Tone. The CSS1-MM LED output port is stabilized to ensure accurate test results per current TIA/EIA requirements. An easy to read LCD display with Backlight shows emitted wavelengths [nm], tone frequency [Hz], and Low battery condition. The CSS1-MM model output port is equipped with a fixed SC connector.

CSM1-2 Optical Power Meter operates at 850/ 1300/ 1310/ 1550 nm and features multiple test Tone detection for fiber identification. The CSM1-2 stores optical references for each calibrated wavelength. An easy to read LCD display with Backlight shows measured power [dBm or µW] or insertion loss [dB], calibrated wavelengths, tone frequency [Hz], and Low battery condition. The CSM1 optical input port accepts Noyes thread-on style adapter caps. One adapter cap, 2.5 mm Universal, is included. A variety of Noyes thread-on style adapter caps (FC, SC, LS, etc.) may be ordered separately.

Weighing only 0.4 lb each, units are compact and convenient for field use. The CSS1-MM Dual LED light source and CSM1-2 optical power meter are fully N.I.S.T. traceable.
