Optical Sub-Assemblies


MACOM’s optical sub-assemblies (OSA) are focused on enabling our customers high performance/high bit rate optical transceivers operating at 100G and beyond. Our current 100G TOSA integrates 4 channels of 25/28G DFB lasers or EML’s with driver IC and a low loss optical MUX.  Our current 100G ROSA integrates four PIN photo-detectors, a quad TIA, and a low loss optical DEMUX. MACOM’s optical sub-assemblies are key components servicing the next generation metro/longhaul networks, datacenter interconnect (DCI) applications, mobile backhaul networks, and high end router/switch applications.
