Abstract

There is provided an optical assembly (100) comprising an optical fiber arrangement (220, 230) and a lens arrangement (120). The lens arrangement (120) is spatially disposed relative to the fiber arrangement (220, 230) so as to be capable of providing an axial substantially collimated beam of radiation in response to receiving radiation from the optical fiber arrangement (220, 230) and capable of providing a focused beam of radiation to the optical fiber arrangement (220, 330) in response to receiving substantially collimated radiation to the lens arrangement (120). The assembly (100) further comprises a configuration of elements (110, 130, 200, 260) for spatially disposing the optical fiber arrangement (220, 230) relative to the lens arrangement (120). The configuration of elements (110, 130, 200, 260) provides for independent adjustment of relative lateral position between the optical fiber arrangement (220, 230) and the lens arrangement (120) in relation to axial position of the optical fiber arrangement (220, 230) relative to the lens arrangement (120). Such independent adjustment assists in fabrication of the assembly (100).

Dependent claims

A communication optical assembly, comprising:

an optical fiber arrangement operable to detachably receive an optical fiber terminated by a ferrule,
a lens arrangement, said lens arrangement being spatially disposed relative to the optical fiber arrangement so as to provide an axial collimated and expanded beam of radiation in response to receiving radiation from the optical fiber arrangement and further to provide a focused beam of radiation to the optical fiber arrangement in response to receiving a collimated beam of radiation to the lens arrangement, and
a plurality of elements for spatially disposing the optical fiber arrangement relative to the lens arrangement, the plurality of elements includes a lens holder, an alignment sleeve, and a fiber stub holder, the alignment sleeve and the stub holder are arranged in an overlapping configuration and provides for adjustment of the lateral position between the optical fiber arrangement and the lens arrangement, the lens holder and the alignment sleeve are arranged in an overlapping configuration and provides for adjustment of the axial position between the optical fiber arrangement and the lens arrangement without the use of screws.
