What Is the Physics of Fiber Optics Trainer Used For?
Light that enters an optical fibre is held inside it by total internal reflection, so it follows the fibre around a bend instead of travelling in a straight line. The opening experiments make this visible: light travelling around corners, coloured light running down a fibre and a photodetector responding to it. Students then see how much light passes from one fibre to another and across a gap, try the fibre optic transmission and reflection sensors, and measure numerical aperture, which describes the range of angles over which a fibre accepts light.
Further experiments turn the trainer into a communication link. The LED is intensity-modulated, meaning the strength of its light follows the signal, and the receiver turns the light back into an electrical signal. Measuring propagation, connector and bending losses shows why fibre length, joints and tight bends matter when an optical link is planned.
What to Specify When Ordering
- The number of trainers, for example one per bench or per student group.
- Any oscilloscope or other instruments you want quoted on the same enquiry.
- Other fibre optic trainers for the same lab, such as the numerical aperture or voice trainers linked below.
- The delivery address or port and your preferred delivery terms.
Frequently Asked Questions
Why is the transmitter a visible red LED?
At 635 nm the LED gives visible red light, so students can watch light leave the fibre, follow a bend and cross a gap between fibres. That makes the light-guiding experiments easier to follow than they would be with an invisible infrared source.
What bandwidth do the analogue and digital links offer?
35 kHz on the analogue link and 50 kHz on the digital link. The LED driver has analogue and digital configurations, and two silicon photodetectors act as receivers.
Which faults can be switched in?
Four. Fault 1 sits in the function generator section, fault 2 in the audio preamplifier, fault 3 in the signal strength section and fault 4 in the audio amplifier. Switching one in and tracing its effect gives practice in fault-finding on a working link.
What fibre does the trainer use?
1000 micron step-index multimode plastic fibre. Two lengths, 1 m and 5 m, come with connectors fitted, so loss can be compared between a short and a long fibre.
Is an oscilloscope needed?
Yes. A 20 MHz cathode ray oscilloscope is other apparatus required for the experiments and is ordered separately; JLab’s Cathode Ray Oscilloscope can be quoted on the same enquiry.
What should an export enquiry include?
The number of trainers, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling needs and a tender reference if one applies.
Who makes this trainer?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of physics, electronics and communication trainers, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is made in JLab’s own works rather than sourced from a trader, so colleges, institutes, dealers and importers deal directly with the maker; every unit is visually inspected before dispatch, and repeat orders and replacement accessories are handled by the same manufacturer. JLab exports worldwide and ships to buyers in every region — Germany in Western Europe, Brazil in South America, Latvia in Northern Europe, the Czech Republic in Eastern Europe and Vanuatu in Oceania are a few examples. Institutional buyers can find tender details on the JLab lab tenders page.
