An optoelectronic device is used with an optical fiber for data transmission and has a transmitter mounted on a printed circuit board (PCB) to emit light. A collimation lens on a lens block receives the light incident thereto. A microstructure on a reflective surface of the lens block has sections that reflect the light into attenuated portions. A focusing lens on the lens block focuses a first attenuated portion from first sections of the reflective surface to the optical fiber. Meanwhile, second sections of the reflective surface reflect a second attenuated portion to another reflective surface on the lens block. The second attenuated portion passes out of a refractive surface on the lens block to an receiver, which is mounted on the PCB adjacent the transmitter. The second attenuated portion of the light can be used to monitor the optical output of the transmitter.

Optoelectronic device having attenuating lens block and source monitoring

An example method of assembling an optoelectronic assembly may include aligning a receptacle with a sleeve that may have a radial flange and with a ferrule that may have a light propagation axis. The method may include axially displacing one or more of the receptacle, the sleeve, and the ferrule such that the receptacle may be positioned at least partially within the sleeve and may at least partially surround the ferrule. The method may include aligning a fiber stub that may have a fiber stub pigtail and a fiber stub flange with the receptacle. The method may include axially displacing one or both of the fiber stub and the receptacle such that the fiber stub may be positioned in close proximity with the ferrule. The method may include coupling the sleeve via the radial flange and the fiber stub via the fiber stub flange with a retention device.

Retention device for optoelectronic connections

An example optoelectronic module may include an optical subassembly (OSA), an optical port block, a housing, and a holder. The OSA may be configured to convert between optical and electrical signals. The optical port block may be attached to the OSA and may be configured to optically align a fiber optic cable with the OSA. The housing may be configured to substantially enclose the OSA and the optical port block. The holder may be configured to couple the OSA and the optical port block to the housing. The holder may be detachably coupled to the optical port block and fixedly coupled to the housing.

Optical subassembly with detachably-coupling holder

In an embodiment, an optoelectronic module includes a printed circuit board (PCB) and a lens block. The printed circuit board (PCB) includes at least one of an optical transmitting or receiving array. The lens block may be configured for directly coupling light between one of the optical transmitting or receiving array to optical fibers in an optical cable. A method may include directly coupling light between one of an optical transmitting or receiving array and a lens block, and further coupling the light through the lens block directly to an optical fiber of an optical cable externally coupled to the optoelectronic module.
