Product Detail
1,F-GX1000 2,Optical mode 3.Analog signal 4.Optical fiber numerical aperture

F-GX-1000 Characteristic of fiber optics and semiconductor laser Experiment contents and related subjects: 1.Cutting and end treatment of fiber. 2.Coupling of fiber with laser and the measurement of coupling efficiency. 3.Electro-optical characteristics of semiconductor laser (threshold current and gain slope). 4.Observe the pattern and polarization of the fiber, the effect on modes caused by fiber bending (interference

modes). 5. Determination of the speed of light in fiber and calculation of the average refractive index of the fiber materials. 6.Modulation, emission, fiber transmission, receiver amplification and demodulation (communication theory) of the analog signal (audio) . 7. Pick-up of the vibration signals. 8. Measurement of the fiber numerical aperture (specific measurement  annexes are needed). Features of the instruments: 1. Using the visible light semiconductor laser which can be modulated as light source, the phenomenon is clear and intuitive; the wavelength is 650nm, the output power is ≥ 10mW and the power stability is ≤ ± 1%; the

frequency modulation range is 10K-200KHz; the laser power meter is three and a half digital meter, the measuring ranges are 200μW, 2mW, 20mW, 200mW and the tunable range; the length of the fiber is 200m. 2.Precise adjustment mechanism of multi-degrees of freedom is employed to couple fibers, so, hands-on abilities of students are cultured. Complete set of equipment: optical experiment guide, optical fiber test device, semiconductor laser, fiber coupler, fiber seats, fiber, polarizer,

laser power indicator, fiber knife, skinning pliers, one-dimensional displacement of the probe light aircraft + 12 steps light detector(optional) , audio signal source, oscilloscope (dual trace 20MHz, self-contain) and etc..
