This Interim European Telecommunication Standard (I-ETS) applies to fibre-pigtailed optical fixed attenuators to be used in single-mode optical fibre transmission networks and which are designed to be spliced into the optical path. This includes splices which are fabricated to produce an attenuation and which are fitted with an appropriate protector. It does not cover variable attenuators or attenuators that are based on connectors.
