How Does It Compare with the Numerical Aperture Trainer?
| Model | Experiments |
|---|---|
| This advanced analogue trainer (EL-FOT-1538) | NA; fibre and cable losses at both wavelengths; E/O and O/E characteristics; linear intensity modulation system with gain, frequency response, waveform distortion and gain-bandwidth product |
| Fibre Optic Trainer for Numerical Aperture | Fibre optic transmitter and receiver; NA of PMMA fibre; loss in the one-metre and five-metre PMMA patch cords; E/O and O/E converter characteristics; intensity modulation system |
Both trainers have the same hardware, from the two switch-selected transmitters to the NA jig and mandrel, so the choice rests on the experiments. Pick this advanced trainer when the practical goes on to measure how the analogue link itself performs.
What Is the Analogue Transceiver Trainer Used For?
In analogue intensity modulation, the signal voltage varies the LED drive current and with it the optical power sent into the fibre; at the far end the phototransistor turns the light back into a current that follows the signal. A linear system keeps that relationship proportional, and the trainer is used to find how far it stays linear, how its output falls away at higher frequencies and how much the waveform distorts. Because PMMA plastic fibre absorbs 850 nm light much more strongly than visible red light at 660 nm, the loss measurements at both wavelengths show why the operating wavelength matters. It suits optical communication practicals in college and polytechnic electronics labs.
What to Specify When Ordering
- Number of trainers — one per bench or per group of students.
- Other fibre optic trainers — the numerical aperture, digital and voice trainers can be quoted together with this one.
- Destination and delivery terms — the country, port or city and terms such as FOB or CIF.
Frequently Asked Questions
Which other apparatus is needed with this trainer?
An AF/RF generator covering 10 Hz to 1 MHz, a digital multimeter, a 20 MHz cathode ray oscilloscope and a digital fibre-optic power meter. They are separate items. JLab lists an A.F. Oscillator Function Generator Cum Digital, a Digital Multimeter and a Cathode Ray Oscilloscope, which can be quoted on the same enquiry.
What is numerical aperture?
For light entering from air, it is the sine of the maximum angle, measured from the fibre axis, at which light entering the fibre end is still guided along the core. A higher numerical aperture means the fibre accepts a wider cone of light. On this trainer it is found with the NA jig.
What does the gain-bandwidth product show?
It is the gain of the link multiplied by its bandwidth, a single figure that combines how strongly the system amplifies a signal with how wide a range of signal frequencies it passes.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling requirements, and the tender reference if the order is for a tender.
Who makes this trainer?
JLab — Jain Laboratory Instruments Pvt Ltd — manufactures it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics and communication trainers and other laboratory equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is assembled at JLab’s own works rather than sourced from a trader, so engineering colleges, institutes, dealers and importers order it factory-direct, every unit is visually inspected before it leaves, and repeat orders go to the manufacturer itself. JLab exports worldwide and ships to buyers in every region — for example Cyprus in Southern Europe, Eswatini in Southern Africa, the Maldives in South Asia, Papua New Guinea in Oceania and Congo in Central Africa. Tender buyers can find details on the JLab lab tenders page.
Other Optical Communication Trainers
- Laser Diode Intensity Modulation and Demodulation Trainer — analogue and digital transmission with a laser diode instead of an LED.
- Advanced Fibre Optic Digital Transceiver Trainer — the digital counterpart, with encoding methods such as Manchester coding.
- Fibre-Optic Simplex Digital Transceiver Trainer — a digital link with rise-time, fall-time and propagation delay studies.
- Fibre Optic Voice Transmitter and Receiver Trainer — audio and voice sent over the fibre.
