Twenty-five beige SC-UPC flange fiber attenuators in a row

Adafruit

Adafruit 25PCS 15dB SC-UPC Flange Fiber Optical Attenuators 2 in 1 Accessories

SKU CH-7J60-RXY2J

Pack of 25 SC-UPC flange attenuators delivering fixed 15 dB single-mode signal reduction for fibre testing and communication systems

  • Precise 15dB attenuation protects sensitive receivers from overload
  • 10% attenuation accuracy ensures consistent signal levels across links
  • Low 0.2dB polarization dependent loss maintains stable transmission
  • High 50dB return loss minimises back-reflection interference
  • 25-piece pack supplies enough attenuators for multi-link deployments

25-Pack SC-UPC Fixed Attenuators

This pack supplies twenty-five single-mode fiber attenuators, each with a 15dB fixed loss and SC-UPC female-to-female connectors. Network engineers and installers use them to bring received optical power into the receiver’s sweet spot during turn-up, testing or permanent deployment.

15dB fixed loss with tight tolerances

Each unit delivers 15dB attenuation with a 10% dB precision window, polarization dependent loss of .2dB and return loss of 50dB. The fixed value means you cannot tune the loss on site; the link budget must already call for exactly 15dB per connector.

Replaces variable attenuators for permanent drops

When a link needs a known, repeatable 15dB drop, these plug-and-play adapters replace bench-top variable attenuators and eliminate drift. They are not suited for links that require adjustable loss or attenuation values other than 15dB.

Questions about this item

Should I buy the 25-piece pack or look for a smaller quantity?

The pack contains 25 SC-UPC female-to-female attenuators, each fixed at 15 dB attenuation.

What does the 15 dB attenuation do to the light level in my single-mode link?

Each attenuator cuts the optical signal by 15 dB with 10 % dB precision, 0.2 dB polarisation-dependent loss and 50 dB return loss.

Will these SC-UPC flange adapters work with standard SC patch cords and panels?

Yes, they are SC-UPC female to SC-UPC female flange connectors designed for direct insertion into standard SC interfaces.
