PklzNet SC-UPC 7dB Single-Mode Fiber Optical Attenuators

PklzNet 7dB SC-UPC single-mode fixed attenuators are plug-and-play adapters that reduce optical power by 7 decibels while preserving signal integrity.

These compact SC-UPC male-to-female inline attenuators are built for single-mode fiber networks where controlled signal reduction is required. 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.

How do these attenuators fit into an optical link?

Install 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.

• 7 dB fixed attenuation for predictable power drop
• SC-UPC male-to-female form factor for standard patch cords and transceivers
• Simple inline connection—no tools or splicing needed

What performance can I expect in testing and production?

Expect consistent attenuation within the specified tolerance and low additional loss from polarization effects. High return loss helps limit back-reflection into transmitters, preserving link stability during measurements and long-term operation.

• Attenuation accuracy around ±10% of 7 dB for reliable signal reduction
• Polarization-related loss ≤0.2 dB to minimize variation with state of polarization
• Return loss ≥50 dB to reduce reflective noise in sensitive equipment

Are these attenuators durable enough for field use?

They are manufactured with impact-resistant materials and a straightforward mechanical design that tolerates routine handling and repeated mating cycles. Their compact housings protect the internal element, enabling safe storage and transport in toolkits and test cases.

• Robust housing to withstand handling and installation stress
• Stable mating ferrule for consistent connector alignment
• Pack of 10 for spare parts or multiple site deployments

Which applications are these best for?

Use these attenuators whenever controlled reduction of optical power is needed without changing fiber routing. They are commonly used in development labs, production test benches, CATV systems, fiber optic troubleshooting, and to adjust receiver input levels in passive networks.

• Field and bench testing of transceivers and receivers
• Signal leveling in FTTH, CATV, and telecom passive links
• Temporary attenuation during equipment setup or maintenance

Who is this for: These PklzNet 7 dB SC-UPC fixed attenuators are aimed at network technicians, lab engineers, and installers who need a compact, repeatable way to reduce optical power in single-mode systems. If you manage fiber test equipment, deploy passive optical networks, or perform receiver sensitivity checks, the 10-piece set provides spares and scalability for multiple sites or ongoing testing routines.
