PklzNet SC APC 7dB Fiber Attenuator 10-Pack

PklzNet 10-pack of 7dB SC APC single-mode fixed fiber optic attenuators provides reliable, plug-and-play signal attenuation for testing, installation, and commissioning of fiber links.

These SC male-to-female fixed attenuators are designed for single-mode APC connectors and supply a precise 7dB loss point for balancing signal levels during setup or diagnostics. Built from high-performance attenuated fiber with durable housings, the adapters deliver low polarization-related loss and high return loss, making them suitable for lab equipment, CATV, and fiber communications where repeatable attenuation is needed.

How accurate and stable is the 7dB attenuation?

Each attenuator is manufactured for high-precision attenuation with a tolerance of ±10% of the rated dB value, ensuring consistent signal reduction across the pack. The units also maintain low polarization dependent loss and strong return loss figures to preserve signal integrity while reducing power.

• Rated attenuation: 7dB fixed per unit
• Tolerance: ±10% of the stated attenuation
• Polarization related loss: ≤ 0.2dB for stable signal behavior
• Return loss: ≥ 60dB to minimize reflections

What connector types and orientations does this kit support?

The set is configured as SC male to SC female for APC (angled physical contact) connections, so it plugs directly into APC ports without additional adapters. This orientation is common in single-mode links and test instruments that use SC-APC interfaces.

• Connector interface: SC male to SC female
• Polish type: APC (angled) for improved return loss
• Compatibility: single-mode fiber systems and APC-equipped test gear
• Form factor: fixed, inline adapter for direct insertion

How easy are these attenuators to use on the job?

They are plug-and-play devices requiring no special tools—simply insert the male end into an APC port and connect your patch or instrument to the female end. The simple, robust design supports quick swapping during field tests or lab measurements, and the compact housings make storage and transport straightforward.

• Installation: direct insertion, tool-free
• Design: compact, impact-resistant housing
• Use cases: commissioning, troubleshooting, and signal leveling
• Package: 10 identical attenuators for repeatable setups

What environments and equipment are these best suited for?

These attenuators are appropriate for fiber communication systems, test benches, cable TV headends, and field commissioning where controlled signal reduction is required. Their electrical-free construction means they can be used in standard telecom racks, lab benches, or portable test kits without affecting system electronics.

• Applications: fiber testing, CATV, telecom installation
• Equipment: optical power meters, OTDRs, transceivers with SC-APC ports
• Environment: lab, rack, or fieldwork with standard single-mode cabling
• Reliability: designed for repeated connect/disconnect cycles

Who is this for: technicians, network installers, and lab engineers who need a compact, consistent way to lower optical power during testing or alignment. The 10-piece pack gives spare capacity for multiple test points or team members, and the fixed 7dB value helps standardize procedures when balancing transmitter and receiver power in single-mode APC systems.
