FIBERYO innovative design is dome type with one hinge in one side and open in another side. It is the most reliable FOSC with the simplest installation in the world. The FOSC is suitable for protecting fiber cable splices in straight-through and branching applications. Based on an advanced formula, the plastic parts are made of injection-molded, high-strength engineering plastic PC by numerical control equipment; therefore effectively prevent products from aging caused by coldness, heat, oxygen and ultraviolet radiation.
