[1] [«Back ||Next »]   Click to Enlarge Optical Fiber Product Range Fibre Optics have revolutionised the way the world communicates today. Optical fibre based communications systems are working today in Telecom, Railways, Defence, Industrial Automation and Medical industries or sectors. Fibre optic training has, therefore, assumed great importance in this scenario of widespread usage of the fibre optic technology. Potential entrants into this technological field have to be well versed and equipped to work with large-scale, real world, fibre optic systems. The problems of setting up an Optical Fibre Lab In order to train these potential entrants effectively, it becomes critical to set up "state-of-the-art" equipped labs at reasonable costs. A task that gets further compounded when one weighs in the the various permutations and combinations that setting up such up such a fibre optic laboratory entails. For, apart from having to identify the required equipment and components, one has to ensure perfect compatibility between components, availability of spares and replenishments, expandability and the sourcing of all this, most often, from multiple vendors - all to be achieved within a limited budget. Finally, at the end of this this difficult exercise there is still no guarantee of full compatibility, support or even cost effectiveness. The complete single-source solution This is where we steps in. Interlabs provides a complete single-source solution to all the above parameters or aggravations. It offers a complete range of products and spares, starting from individual Optical Fibre Trainers to versatile and comprehensive Optical Fibre Laboratory Systems. A product range that encompasses a comprehensive list of accessories from cables to links and connectors, power sources to power meters... all guaranteed to be not just compatible but completely upgradeable. And backed by a range of options for training personnel/students in optical fibre concepts and practices. Benchmark, in fact, guarantees that students can start working in the laboratory right from the day one. See Enlarge Click to Enlarge The Optical Fibre Trainer Kit The Interlabs 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 Interlabs 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 power source. (The optional 850nm power source can be ordered separately). 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 demonstrated 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 of lab personnel. What do the 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 fibres. 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. See Enlarge Click to Enlarge Optical Fiber Lab.

See Enlarge Click to Enlarge Network & Data Security Training System The Interlabs i-SECURIT is a network and data security training system, that has been jointly developed by Interlabs Electronic Systems and AU-KBC Research Centre, Anna University to educate and train users on different real world network security threats and data encryption methods. Innovative Design Allows Real Life Training The Interlabs i-SECURIT is a complete system with two interconnected real life networks – the “Trusted Network” and the “Black Network”. These networks are isolated from the real world i.e. any corporate or campus LAN and the Internet. The i-SECURIT Central Control Unit (CCU) runs the network services, administration and control methods. The Black Network users attempt to compromise the services by different attacks, such as Intrusions, Password Cracking, and Denial of Service. The trusted network users simultaneously work on, and are trained to deploy, suitable counter measures to keep network services running properly. The Interlabs i-SECURIT covers a large gamut of network security threats and its users can obtain hands-on experience with a wide variety of network security issues and cryptography methods. The course design allows the learner to read about a concept, witness a demonstration and then actually practice its execution. This meets the study flow of beginners as well as industry professionals. Through a single Interlabs i-SECURIT, you can connect up to 15 PCs, with one slot reserved for the network administrator, and can start working with as little as two to three PCs. Courseware Interlabs has worked with experts in the field of network security and cryptography to create comprehensive learning material for conducting complete network security courses. The course material has been presented by pedagogy experts for ease of learning and long term retention. Users can follow the theory and go through the exercises for a complete understanding of the concepts through self study. This also makes it ideal for user paced learning.
