"A ""creativity-friendly"" kit for technicians, experimenters, scientists and enterprising students who are searching for a quick solution for prototypes or special-purpose interfaces requiring fiber optics capabilities. This very low-cost ""active link"" requires a single +5-volt power supply and interfaces with all TTL/CMOS logic. It includes 10 meters of 1000 µm plastic optical cable; efficient dry, non-polish connectors, bulkhead interfaces, and splices; integrated photodetector(s) and LED(s); and top-quality multi-layer printed wiring boards. Full instructions and technical data sheets complete the package. The operable range of both kits can be extended to 60 meters with additional cable purchased separately. Designer's Kits have been the basis of many fiber optics ""brainstorms"" and solutions. "
