Abstract
An optical subassembly is provided. A mounting structure having a plurality of angled conductive traces is disposed on a first surface of the mounting structure. A holding device, coupled to a second surface of the mounting structure, has a plurality of optical channels. A laser optical device is electrically connected to the conductive traces on the mounting structure. An optical signal is emitted or received by the laser optical device and is converted to an electrical signal. The electrical signal is transmitted by way of the plurality of angled conductive devices to the plurality of optical channels.
