Codecom Optical Fixed Attenuators provide precise, stable signal level reduction for singlemode fibre optic networks. Available in both plug-type and in-line configurations across all major connector formats, these attenuators are used wherever received optical power needs to be reduced to within the operating range of sensitive receiver equipment.

Each attenuator is manufactured to premium-grade quality standards with triple visual inspection at 800× magnification (after polishing, before assembly, and before dispatch) and 100% geometrical verification of end-face radius, fibre offset, and fibre height. With optical power handling up to 1000 mW (1W) and a mating durability exceeding 500 cycles, Codecom attenuators deliver reliable, repeatable performance in demanding telecommunications and data centre environments.
