How Does It Compare with the Advanced Fiber Optics Trainer?
| Model | Link | Optical channels | Transmitters and receivers |
|---|---|---|---|
| This trainer (EL-AET-1477) | Simplex, analog and digital | 660 nm | 1 LED transmitter; 1 photodetector |
| Advanced Fiber Optics Trainer | Full duplex, analog and digital | 660 nm and 950 nm | 2 LED transmitters; 2 photodetectors |
Both trainers carry AM, FM and PWM modulation and demodulation, a 4.096 MHz crystal clock, an on-board function generator, a voice link and switched faults on the transmitter and receiver. Choose the Elementary model for a simplex link on a single 660 nm channel; the Advanced Fiber Optics Trainer works full duplex on two wavelengths and also offers PC-to-PC communication through RS232 ports with software.
What Is the Elementary Fiber Optics Trainer Used For?
An optical fiber link converts an electrical signal into light at an LED, guides it along the fiber by total internal reflection and turns it back into an electrical signal at a photodetector. This trainer lets students build that link for analog and digital signals, compare amplitude, frequency and pulse-width modulation, and measure the losses and the light-gathering ability of the fiber. Red light near 660 nm suits PMMA plastic fiber, which has one of its low-loss windows in that region, and the thick 1000 micron fiber is easy to handle on a student bench. The trainer fits fiber optic communication practicals in BSc and MSc physics and electronics, diploma courses and engineering programmes in electronics and communication. Experiments that can be performed:
- Setting up a fiber optic analog and digital link
- AM system using analog and digital input signals; frequency modulation system; pulse width modulation system
- Propagation loss in optical fiber, bending loss and measurement of numerical aperture
- Characteristics of the E-O converter (LED) and of the fiber optic communication link
- Setting up a fiber optic voice link using amplitude, frequency and pulse width modulation
- Study of switched faults in the AM, FM and PWM systems
- Propagation loss using an optical power meter (optional accessory)
What to Specify When Ordering
- Model — this Elementary trainer or the full-duplex Advanced Fiber Optics Trainer.
- Optional accessories — say whether you want the optical power meter and the 5 m or 10 m fiber cable.
- Mains frequency — mention it if your supply needs the 60 Hz version.
- Quantity — the number of trainers for your communication lab.
Frequently Asked Questions
What comes with the Elementary Fiber Optics Trainer?
The trainer is supplied with a line cord, manuals, the NA measurement jig, a mandrel for bending loss, fiber cables, a microphone, a headphone and a set of patch cords.
Is an optical power meter included?
No. The optical power meter is an optional accessory, used for the propagation-loss experiment that calls for a power meter.
What kind of optical fiber does the trainer use?
Step-index multimode PMMA plastic fiber with standard SMA connectors. Its numerical aperture is better than 0.5 and its acceptance angle better than 60°, which makes alignment forgiving for students.
How are faults introduced for fault-finding practice?
Through switched faults — four in the transmitter and four in the receiver — for studying their effect on the AM, FM and PWM systems.
What power supply does it need?
It runs on 220 V ±10%, 50 Hz mains, with 60 Hz available on request, and draws about 3 VA. The DC supplies for the circuits are built in.
What information is needed for an export quotation?
Please give the number of trainers, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling requirements and, for tenders, the tender reference.
Who manufactures this fiber optics trainer?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India, and handles the quotation itself as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics, communication and science teaching equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The fiber optics trainer is assembled in JLab’s own works rather than bought from a trader, so universities, colleges, dealers and importers order it straight from the maker, each unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — Norway in Northern Europe, Croatia in Southern Europe, Fiji in Oceania, Trinidad and Tobago in Central America and the Caribbean, and South Africa in Southern Africa, among others. Tender information is on the JLab lab tenders page.
