PRODUCTS – FIBRE OPTICS – OPTICAL FIBRE TRAINING KIT (OFT)
The Benchmark Optical Fibre Training Kit – OFT – is a powerful,
versatile and cost-effective experimenter kit ideal for training purposes at
all levels and was developed in a joint effort by IIT-Madras and Benchmark
Electronic Systems. The first trainer kit was built in 1988. Over the years,
as per feedback from faculty all over the country, new versions were developed
and built. Currently, the OFT is in its fourth version.
The OFT training kit comprehensively covers all aspects of fibre optic communication
and works at 650nm and 850nm wavelengths. Recognized
by IEEMA as a "best product" in 1997, this self-contained kit
has all the accessories required to conduct experiments and, consequently,
ensures that the laboratory is
fully operational from day one.
Powerful, versatile, cost-effective...
The Benchmark OFT experimenter kit comprehensively covers all aspects of fiber
optic communication and facilitates demonstration, training
and experimentation in basic and advanced concepts that include:
- Principles of Fiber Optics
- Basics of Digital Base Band communications
- Experimentation and development in fibre optic digital communication
Moreover, all accessories required to conduct basic experiments and to interface
to external circuitry are provided with the kit including a 650nm and
an 850nm power source.
The entire circuit
is enclosed in a high strength molded plastic box, protecting the components
from students’ mishandling.
The kit has a comprehensive manual covering theory concepts, experiment
details, circuit/block diagrams and commercial applications of the
concepts ensuring minimal intervention from laboratory personnel.
In short, this comprehensive trainer not only enables students to start learning
but achieves this with minimal training
What do students learn?
The trainer kit enables the student to work on fully operational, integrated
voice/data fibre-optic communication links (digital and analog). Students
work with and become comfortable in using optical fibres through a series
of carefully designed experiments and exercises detailing the characteristics
of optical fibres. The set of experiments takes the students through
digital communication technologies and principles used in setting up
commercial communication systems. And comprehensively covers one semester
course on Fibre Optic Communication as per most university syllabi.
The training modules are divided into experiments and applications:
The basic experiments cover Fibre Optic Links, characteristics of fibre optic
links, losses in fibre links, setting up digital communication links
and the limitations of fibre links like pulse broadening in multimode
- In the advanced set of experiments & applications the student is guided
to design solutions using the concepts demonstrated in the basic experiments.
These modules guide them to design and interface their own communication circuits & systems
through the trainer kit.
- The availability of expansion slots and the modular circuit design enables
advanced project work by students.
