Sold as a pack of 10, they combine sturdy mechanical construction with predictable optical behavior—useful for testing, leveling receivers, or preventing overload in passive optical networks. Performance specs include ±10% attenuation accuracy, polarization-related loss ≤0.2 dB, and return loss ≥50 dB, making them suitable for lab and field use.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these attenuators fit into an optical link?\u003c\/h3\u003e\n\u003cp\u003eInstall the adapter between SC-UPC connectors: plug the male end into the transmitter or patch panel and mate the female end with the receiving connector. The internal, fixed attenuation element lowers optical power without requiring calibration, so you get repeatable results wherever you deploy them.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e7 dB fixed attenuation for predictable power drop\u003c\/li\u003e\n  \u003cli\u003eSC-UPC male-to-female form factor for standard patch cords and transceivers\u003c\/li\u003e\n  \u003cli\u003eSimple inline connection—no tools or splicing needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance can I expect in testing and production?\u003c\/h3\u003e\n\u003cp\u003eExpect consistent attenuation within the specified tolerance and low additional loss from polarization effects.
