The DLS 355 provides a 2 kHz tone output which is recognized by the RP 4XX series power meters; the incoming 2 kHz signal is identified and an audible alert is provided by the power meter. This 2kHz signal will also allow fiber identification when used with non-invasive fiber identifier devices, such as the LFI 110.
