SC APC Simplex Fiber Optic Adapter with Internal Side Shutter
Elevate your network safety and performance with the SC APC Simplex Side Shutter Adapter from Chengdu Focus Infra Materials. Specifically engineered for high-density FTTH deployments and enterprise environments, this adapter features an innovative internal shutter mechanism designed to protect both technicians and sensitive optical components.
The "Side Shutter" Advantage: Safety Without Compromise Unlike traditional dust caps that are easily lost, our Internal Side Shutter provides automatic protection.
Eye Protection: The shutter automatically blocks laser light when the connector is unplugged, preventing accidental eye injury from live fiber signals.
Dust Contamination Shield: The spring-loaded mechanism remains closed until a connector is inserted, effectively sealing the ceramic sleeve from airborne contaminants and ensuring optimal signal integrity (IL < 0.2dB).
Capless Efficiency: Eliminates the need for manual dust caps, accelerating installation speed and reducing site waste.
Key Features:
1. Superior Alignment: Equipped with a high-precision Zirconia Ceramic Sleeve to ensure exact ferrule mating and ultra-low insertion loss for Singlemode (SM) applications.
2. APC Precision: The green housing signifies the Angled Physical Contact (APC) polish compatibility, essential for minimizing back-reflection (Return Loss ≥ 65dB) in high-speed video and data transmission.
3. Flange Design: Includes a standard flange for secure mounting in patch panels, wall outlets, or ODF boxes.
4. Premium Materials: Manufactured from flame-retardant, high-impact polymer (UL94V-0) to withstand rigorous industrial environments.
