Abstract: A multi-channel optical transmitter or transceiver includes an optical multiplexer with input and output ports on a single side. The optical multiplexer receives optical signals at different channel wavelengths on a plurality of mux input ports on one side and combines the optical signals into a multiplexed optical signal, which is output on an optical output port on the same side. The optical multiplexer may be located at a distal end of a transceiver or transmitter housing. In one embodiment, the optical multiplexer is a reversed planar lightwave circuit (PLC) splitter including splitter output ports that are used as the mux input ports and a splitter input port that is used as the mux output port. The mux input ports may be optically coupled to respective transmitter optical subassembly (TOSA) modules with optical fibers.

Abstract: In accordance with an embodiment, a transmitter optical subassembly (TOSA) having one or more recessed mounting regions is disclosed in order to decrease the overall footprint of the TOSA within an optical transceiver housing. The TOSA includes a housing having at least a first sidewall and a second sidewall disposed on opposite sides of the housing relative to each other. The housing further includes a first step portion defined by the first sidewall and a first recessed mounting region extending from about the first step portion along the longitudinal axis towards the second end. The first recessed mounting region is defined by an external surface of the first sidewall that is offset from a surface defining the first step portion by a first offset distance. The first recessed mounting region includes at least one sidewall opening to couple to optical component assemblies.

Abstract translation: 根据实施例，公开了具有一个或多个凹入安装区域的发射机光学子组件（TOSA），以便减少光收发器外壳内的TOSA的总占地面积。 TOSA包括具有至少第一侧壁和设置在壳体的相对侧上的第二侧壁的壳体。 壳体还包括由第一侧壁限定的第一台阶部分和从第一台阶部分沿着纵向轴线朝向第二端部延伸的第一凹入安装区域。 第一凹入安装区域由第一侧壁的外表面限定，第一侧壁的外表面从限定第一台阶部分的表面偏移第一偏移距离。 第一凹入安装区域包括至少一个侧壁开口以耦合到光学部件组件。
