Build-out Attenuators

Build-out Attenuators

Daro Connectivity provides Senko’s range of build-out attenuators for single mode applications.  Build-out attenuators are a passive optical device used to lower the magnitude of a light signal with no significant change to the waveform.

This is often a key requirement in Dense Wave Division multiplexing (DWDM), Erbium Doped Fibre Amplifier (EDFA) and over-powered fibre optic system applications where the receiver cannot accept the signal generated from a high-power light source.

Attenuators are a simple solution with a plug style interface at the front and a receptacle interface at the rear.

The design enables quick, easy installation into bulkhead adaptors within a patch panel; in-line between two optical patch cords or into the optical receiver.

  • Single (1310nm), dual (1310-1550nm) or broadband (1250-1625nm) wavelength versions available
  • UPC or APC end-face polish versions available (interface dependant)
  • FC, SC and ST attenuators have metal housings
  • LC and MU attenuators have moulded polymer single-piece housings
