Value for Money
Fiber Optika completely understands the cost concerns of our customers for their investment in our educator kit: Light Runner. We recommend our customers to evaluate the cost and real value of Fiber Optika‟s teaching package by comparing the ultimate cost and time required for multiple purchases of the independent teaching packages for separate experiments, with the direct purchase of a robust self-contained Light Runner educator kit. Light Runner is not just any other fiber optics training solution but a comprehensive fiber optics bench-top laboratory solution that supports as many as 40+ experiments for optical labs using multiple technologies such as WDM, EDFA, OTDR and OADM.
Light Runner successfully replaces the existing training kits that offer only a limited number of experiments and costs less than half of various kits put together to provide a broad range of 40+ experiments.
Unlike the plastic fiber typically used in the training kits available in the market, Light Runner not only uses original telecom grade silica fiber and components, but also has been developed using high quality best industry practices.
Several units of Light Runner have already been sold to our international clientèle, who have been using it for long time now. We take pride in the fact that so far we have not received any complaints or repair requests for Light Runner from any of our clients worldwide.
Integrated modular nature of Light Runner further adds to the robustness of the kit as an issue in any particular module will not impact the functioning of other modules and hence will prevent the whole system from becoming obsolete.
The other major aspect is the Light Runner proprietary software to support extensive literature including: student manuals which describe the relevant background theory and associated key fiber optic concepts and experimental procedures; instructor‟s manual with provision to store and review student‟s experimental results at any point in time; detailed lecture or background notes with case studies, design exercises and tutorials with solutions.
Light Runner comes with a warranty period of 12 months. Under warranty period we take complete ownership of repair, replace or exchange of the kit without incurring any additional cost to our clients. Our post-sales services strongly rely upon business commitments, quick turnarounds and client satisfaction.When compared to the real cost and time required in purchasing several kits for different laboratory experiments, we strongly believe that Light Runner offers the tutor excellent
value for money. This is further supported by the fact that we have sold several Light Runner kits internationally and continue to generate regular repeat business from our worldwide customer base.
How is Light Runner different from its competitors
Light Runner is one of the world‟s most comprehensive laboratory teaching packages in the photonics field. Other commercially available photonics “teaching” equipment tends to simply demonstrate some features of the technology (and in most cases these are limited to very basic features), rather than enabling students to investigate the important physical principles and key technical issues relevant to their lecture course.
For example, none of the competition (with so called fiber communications kits) allows user to experimentally investigate the key issues of WDM and EDFA and to determine how these factors limit the overall performance of a fiber communications system. Light Runner enables the students to investigate the key issues (some of them mentioned below) without any additional components requirement.
- Optical amplification in a WDM Link
- Adding and Dropping of Channels in a WDM link
- Characterization of WDM Mux and Demux
- Characterization of Erbium Doped Fiber Amplifier
- Characterization of FBG and Circulator
- Analyzing spatial resolution technique through OTDR
- Bit Error Rate and Eye Pattern Analysis
- Analog and Digital Fiber Optic Link
- Power Budgeting of a Fiber Optic Link
- Rise Time Budgeting of a Fiber Optic LinkKey differentiating features of Light Runner which distinguishes it from other competing products are as follows:
- Advanced proprietary software for real time optical control and monitoring. Provides comprehensive literature, theoretical concepts and experiment details through its user friendly software, providing an interactive learning experience and ready references for both students and tutors.
- In addition to ease of use, serviceability and scalability, Light runner is a complete standalone solution that does not require any external equipment such as pulse generator, CRO, power meter, fiber spools, etc.
- Having already sold several units of Light Runner to our international clientèle, who have been using it for long time now, we take pride that so far we have not4
received any complaints or repair requests for Light Runner from any of our
clients worldwide.

When we ordered our first Light Runner system from FiberOptika in 2009, our plan was to replace some outdated experiments in our student laboratory on optical communication systems by a setup with up-to- date components. However, we found that the Light Runner system was fitting our needs perfectly and with some additional systems we are now running all experiments of the student laboratory with Light Runner systems. We found the included manual very helpful for the preparation of the students as well as for the laboratory tutors.Dr.Ing. ReinhardCaspary(InstitutfürHochfrequenztechnik)
- On the LR kit, I think it has many advantages and interests: it is modular, complete, requires no additional measuring equipment (oscilloscope). The proposed documentation (in the software interface and on the book) is very well done. It is quite detailed and clear drawings make it easy to perform the experiments. I have also appreciated: the possibility of other experiments than those offered. It is possible to imagine their own specific manipulations. In summary, I was pleasantly surprised by the ease of use of this LR Kit and very grateful to AbhayKatrela for the quality of training that he has produced.Dr. Pascal Ney, Company Manager, DIDA Concept, France. 17
