ACT SC Fiber Optic Attenuator 5 dB Single-mode SC/UPC Metal Housing EA4005

In fiber optic networks, excessive optical power can saturate receivers and degrade signal quality. The ACT SC Fiber Optic Attenuator 5 dB solves this by precisely reducing signal strength by 5 dB, ensuring optimal performance in single-mode systems.

Who is it for

Network engineers and technicians working with SC/UPC single-mode fiber links who need to balance optical power levels in telecom, CATV, or data center environments.

Main features

• Fixed 5 dB attenuation with ±0.5 dB tolerance for consistent signal reduction.
• SC/UPC connector compatible with standard single-mode fiber interfaces.
• Durable nickel-plated brass housing for reliable mating over 1000 cycles.
• Wide operating temperature range from -40°C to +75°C.
• Low polarization dependent loss (≤0.2 dB) and high return loss (≥50 dB).
