  • Custom color options

Armadillo Loopbacks are available in single mode (9um), multimode (50um or 62.5um), and laser optimized (50um) versions, with definable attenuation from 0-24db. In addition to industry standard colors, we offer custom shell colors options to suit your particular application.


  • Improved shell rigidity, durability, and longevity by fusing top, bottom, and connectors to form composite unit
  • Connector design improves product lifespan by eliminating potential connector part separation
  • User-defined attenuation levels enables precise performance for application specific testing and troubleshooting
  • Availability in any color provides a quick and easy way to distinguish between devices, attenuation levels, test set-ups, or associated products; or simply color coordinate with the end product(s) for a cohesive, polished appearance
