The SC APC/PC Fiber Optic Attenuator is a high-precision passive device designed to reduce optical signal power in fiber optic networks. Available in fixed (5dB, 10dB) and adjustable versions, it ensures optimal signal strength for sensitive equipment, preventing overload and distortion.
Key Features & Benefits
Precision Attenuation - Accurately controls signal power for stable performance.
SC Connector Options - APC (Angled Physical Contact, green) or PC (Physical Contact, blue) for low back reflection.
Low Insertion Loss - ≤0.5dB for minimal impact on signal integrity.
High Return Loss - APC: ≥65dB | PC: ≥50dB for superior signal clarity.
Durable Construction - Ceramic ferrule & metal housing for long-term reliability.
Wide Compatibility - Works with single-mode (SM, 9/125µm) fiber systems.
