| Tempo 558B High Intensity InGaAs Power Optical Meter Description: |
Tempo 558B performs Insertion Loss and Link Loss Testing. The 558B 2mm InGaAs optical power meter is capable of measuring significantly higher power levels than the 555B (1mm InGaAs) and 557B
(3 x 3.5mm Si) instruments. With a measurement range of +25 to -30dBm1, the 558B is particularly suited for performing measurements on CATV systems, optical amplifiers, and other high power devices.
Paired with a 250 Series LED source or 260 Series laser source, the 558B optical power meter is ideal for insertion loss testing of multimode
and single-mode fiber optic cables and onnectors. The 558B optical power meter can also be used for link loss testing of installed cable plants.
The multi-wavelength reference storage capability of the 558B optical power meter permits convenient insertion and link loss testing at
different transmission windows if a 252A/252B dual LED source or 262A dual laser source is used.
Output Power Measurements.
Tempo 558B optical power meter simplifies output power measurements of optical amplifiers, transmitters, and other high output light sources.
The three calibration wavelengths, 2mm InGaAs photodetector, and wide dynamic range also make the 558B suitable for a variety of other
high power measurements.
In addition, a broad range of Snap-On Connector adapters for both industry standard fiber optic connectors, and other less common types, makes the 558B an indispensable tool for technicians and others working with light-based transmission systems.
