AOFPLUS's SC optical keystone jack coupler is built for single-mode OS2 fiber systems and engineered to deliver dependable long-distance optical performance. Low insertion loss and superior return loss help preserve signal fidelity across extended runs for telecom, FTTH aggregation points, and backbone links. The blue housing follows industry color coding to simplify identification and reduce installation errors in mixed-cable environments. A high-quality zirconia ceramic sleeve guarantees precise ferrule alignment and repeatable mating cycles, while the UPC-polished endface minimizes back reflection for improved signal continuity. Designed for snap-in keystone plates and standard patch panels, this adapter provides secure mechanical retention, consistent optical contact, and long-term durability for professional network deployments.
