Embodiment Construction

[0017] As mentioned above, the continued scaling of optical transceivers and related components presents a number of challenges that cannot be underestimated. For example, the optical component assembly can be press-fitted into an optical subassembly during manufacture, such as a transmitter optical subassembly (TOSA) and a receiver optical subassembly (TOSA) , ROSA). The optical component assembly may include a base designed to be combined with the optical subassembly housing by a press-fit, which may also be considered a friction-fit or interference-fit. fit), and this optical component assembly can further provide a mounting surface for combining with optical components, such as filters, mirrors or photodiodes. Optical components can be mounted directly to the mounting surface, or indirectly through mounts designed to hold the optical component in a specific orientation. In any case, when the optics assembly is press fit into the optics subassembly housing, the optics ass...

Abstract

The present disclosure is directed to a keyed optical component assembly that ensures that the same has a proper orientation when press-fit into or otherwise coupled to a complimentary opening of an optical subassembly housing. In an embodiment, the keyed optical component assembly includes a base portion defined by a first end and a second end disposed opposite the first end along a longitudinalaxis. A first arcuate region extends from the first end towards the second end and transitions into a tapered region. A second arcuate region extends from the second end towards the first end and alsotransitions into the tapered region. Therefore, the tapered region extends between the first arcuate region and the second arcuate region, and generally tapers / narrows from the second arcuate regionto the first arcuate region. The resulting shape of the base portion may generally be described as an asymmetric tear-drop shape.

Description

technical field [0001] The present application relates to an optical transceiver module, and more particularly to an optical element having a keyed bottom that helps ensure proper alignment when the optical element is combined with an optical subassembly housing. Background technique [0002] Optical transceivers are used to transmit and receive optical signals for a variety of applications including, but not limited to, network data centers, cable TV broadband, and fiber to the home (FTTH). For example, optical transceivers provide higher speed and bandwidth over longer distances than transmission over copper cables. For example, in terms of maintaining optical efficiency (power), thermal management, insertion loss, and manufacturing yield, the need to provide higher speeds at lower costs in smaller optical transceiver modules is challenging of. [0003] An optical transceiver may include one or more transmitter optical subassembly (TOSA) and receiver optical subassembly ...
