Precision Optical Power Control for Female Port Applications
Our FC/UPC Female Fixed Optical Attenuator is a high-performance passive device engineered to precisely reduce optical signal power at the receiving end of a fiber link. Designed with an FC/UPC female-to-female configuration, this attenuator enables direct integration between two FC/UPC male patch cords or equipment ports, providing reliable power management without the need for additional conversion adapters.
This bulkhead-style attenuator serves as the ideal solution for balancing channel power in DWDM systems, protecting sensitive optical receivers from saturation, and ensuring optimal signal quality across your fiber optic network.
Key Features & Benefits
Female-to-Female Configuration: Features FC/UPC female connectors on both ends, designed to connect directly to standard FC/UPC male patch cords. The connector interface is suitable for a 2.5mm ferrule, ensuring compatibility with standard FC hardware.
High Return Loss Performance: The Ultra Physical Contact (UPC) polish delivers return loss of ≥50dB, minimizing back reflections that can cause signal degradation, noise, and instability in high-speed transmission systems.
Precision Attenuation Values: Available in fixed attenuation values from 1dB to 30dB, with industry-leading accuracy-±0.5dB for 1-9dB values and ±10% for 10-30dB values-ensuring precise power level control.
Broadband Compatibility: Optimized for single-mode operation across the 1260–1620nm wavelength range, supporting both 1310nm and 1550nm transmission windows.
Low Polarization Dependent Loss: PDL ≤0.2dB ensures consistent attenuation performance regardless of signal polarization state, critical for maintaining signal integrity in complex optical networks.
High Power Handling Capacity: Supports maximum optical input power up to 300mW, making it suitable for EDFA amplifiers, DWDM systems, and high-power transmission applications.
Rugged & Reliable Construction: Durable metal housing with precision zirconia ceramic ferrules and sleeves provides excellent mechanical stability, ensuring long-term reliability in both indoor and outdoor environments.
