They are plug-and-play, suitable for FTTH, telecom nodes, or temporary setups. Our connectors use precise ceramic ferrules to keep signal loss low and return loss high. You can customize connector type, fiber type, housing, and. CS connectors are the next evolution in delivering more performance and a 40% size reduction at the same time. As official distributors of patent owners Senko, Pro Optix are excited. A fiber optic connector is a mechanical device used to align and join optical fibers, enabling light to pass through with minimal loss. Push-pull tabs can easily be inserted and removed from high density cabling without special tooling.
