Jlab Export is a leading Fibre Optic Trainer for Numerical Aperture Manufacturer,and suppliers in India
Fibre Optic Trainer for Numerical Aperture (code EL-FOT-1540) is a fibre optic trainer for measuring the numerical aperture of PMMA plastic fibre and the loss in PMMA patch cords, together with basic studies of the transmitter, the receiver and the electrical-to-optical and optical-to-electrical converters. An NA jig and a mandrel are part of the trainer. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with the Advanced Analogue Transceiver Trainer?
| Model | Experiment focus |
|---|---|
| This NA trainer (EL-FOT-1540) | Numerical aperture and patch-cord loss of PMMA fibre; transmitter, receiver and converter characteristics; an intensity modulation system |
| Advanced Fibre Optic Analogue Transceiver Trainer | Numerical aperture and fibre losses, plus a linear intensity modulation system studied for gain, frequency response, waveform distortion and gain-bandwidth product |
Both trainers have the same hardware, weight and dimensions, so the choice depends on how far the course goes into analogue link measurements, which the advanced trainer’s experiment list covers in more detail.
What Is the Numerical Aperture Trainer Used For?
Numerical aperture describes how wide a cone of light a fibre can accept and guide, so it sets how easily light from an LED can be coupled into the fibre, and loss sets how far a signal can travel before it becomes too weak to detect. This trainer puts both measurements for PMMA plastic fibre on one bench. The converter studies then show how the light output follows the LED current and how the phototransistor current follows the received light — the relationship on which the intensity modulation experiment is built.
What to Specify When Ordering
- How many trainers the lab needs.
- Whether you want the advanced analogue trainer or another fibre optic trainer quoted with it.
- The delivery city or port and, for institutions, any tender reference.
Frequently Asked Questions
How is numerical aperture worked out from the jig reading?
Light leaving the fibre end spreads into a cone and forms a spot on the jig’s scale. If the spot has radius r at distance L from the fibre end, the half-angle θ of the cone satisfies tan θ = r / L, and for light in air NA = sin θ.
Why does the trainer have two patch cord lengths?
When the coupling at the ends is similar for both cords, the difference between the one-metre and five-metre readings is the loss of the fibre itself over the extra four metres, which can then be expressed per metre.
What else is needed to run the experiments?
An AF/RF generator (10 Hz to 1 MHz), a digital fibre-optic power meter, a digital multimeter and a 20 MHz cathode ray oscilloscope, all separate items. JLab’s Digital Multimeter, Cathode Ray Oscilloscope and A.F. Oscillator Function Generator Cum Digital can be quoted on the same enquiry.
What details should an export enquiry give?
The number of trainers, the destination country and port or city, the delivery terms you want (for example FOB or CIF), packing or labelling needs and any tender reference.
Who makes the Fibre Optic Trainer for Numerical Aperture?
JLab (Jain Laboratory Instruments Pvt Ltd) manufactures it at its works in Ambala, Haryana, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of optics, electronics and communication trainers in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is made in JLab’s own works rather than bought from a trader; colleges, institutes, dealers and importers order it factory-direct, each one is visually inspected before dispatch, and repeat orders come back to the manufacturer. The company holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — Sierra Leone in West Africa, Cambodia in Southeast Asia, Iraq in the Middle East, Kazakhstan in Central Asia and Tonga in Oceania, for example. Details for tender purchases are on the JLab lab tenders page.
