Description
Benchmark Hand-held Fibre Optic source FOPS for fibre optic test and measurement can be used to measure attenuation in optical fibre cables, connector and splicing losses and to characterize optical attenuators, directional couplers, photodetectors, etc. The FOPS -101 uses a stabilized high speed GaAs infrared LED emitting at 880nm.The typical power coupled into 50/125μ Graded Index (GI) fibre with numerical aperture (NA) of 0.2 by FOPS is –20dBm. This optical power can be varied down to approximately 5dB range. The bit rate can be set to one of 64, 128, 256, 1024 and 2048 Kbps. The equipment operates in three modes, viz. Internal (INT), External (EXT) and Continuous wave.
Benchmark Hand-held Fibre Optic power meter FOPM - 101 for the wavelength range 600nm & 850nm uses a large area Silicon Photodetector as sensor. FOPM - 102 for the wavelength range 850nm to 1550nm uses a large area Germanium photodetector as sensor. The FOPM - 101 power meter has been calibrated at 850nm and FOPM - 102 power meter has been calibrated for 850nm, 1300nm and 1550nm and the calibration wavelength is switch selectable. It can measure optical power from –60dBm (1nW) to +3 dBm (2mW). A three and half digit LCD display provides a direct readout in dBm, with a resolution of 0.1 dB. The power meter is provided with universal adaptor with ST interface. It allows the measurement of optical power even at high bit rates as it reads the average power.
