Abstract

The invention relates to a method for operating an optical protection element and/or for protecting an optical network, especially an optical distribution network as part of a telecommunications network, by means of the optical protection element,wherein the optical protection element is configured to protect the optical distribution network on a first side of the optical protection element, at least in part, from inappropriate input signals arriving from a second side, opposite the first side, of the optical protection element, wherein inappropriate input signals comprise optical signals having an optical input power exceeding a threshold value and/or optical signals outside of a predefined optical spectral range,wherein the optical protection element comprises an optical power detector on the second side of the optical protection element as well as a variable optical protector being configured to be switched between at least a first and a second mode of operation, the first mode of operation being a transmission mode of operation allowing the transmission of optical signals for the optical distribution network being operatively used, and the second mode of operation being an optical protection mode of operation,wherein, in order to operate the optical protection element and/or to protect the optical distribution network from inappropriate input signals, the method comprises the following steps:-- in a first step, and while the variable optical protector being in its first mode of operation, the optical power detector detects an inappropriate input signal,-- in a second step, the variable optical protector is switched to its second mode of operation,-- in a third step, the variable optical protector is triggered to be switched to its first mode of operation.
