Abstract: The present embodiment relates to a light-emitting module comprising: a substrate; a light source which is arranged on the substrate and emits laser light; a holder arranged on the substrate; a diffuser lens arranged in the holder and over the light source; and a diffuser ring for supporting the diffuser lens, wherein the diffuser lens comprises a plurality of microlenses, and the holder comprises an opening formed above the diffuser lens and a stopping protrusion for inhibiting the diffuser lens from being separated through the opening.

Abstract: A CAS data processing apparatus of an STM-1 interface block which is capable of processing CAS signaling data in real time is disclosed. The CAS data processing apparatus of the STM-1 interface block preferably includes a plurality of framers, which separately read signaling data streams from 21 E1 links, a CPU, which outputs a start signal in the CAS signaling data processing, a CAS signaling processing unit, which reformats the signaling data streams inputted from the plurality of the framers into report data in order of the each link, and a Common Memory, which stores the report data outputted from the CAS signaling processing unit.
