A lens block is configured such that one or more lens pins can mechanically couple to the lens block and such that the lens block can mechanically couple to a fabricated package that includes light transmitting and/or detecting components. At least one lens pin has a fiber stop configured to accept a fiber end prepared for use with a first type of fiber connector. A fiber stop disk alters the configuration of the lens pin such that the lens pin can compatibly accept a fiber end prepared for use with a second different type of fiber connector not withstanding that the fiber stop is configured to accept a fiber end prepared for use with the first type of fiber connector. ## Claims ### Claim 1 A modular optical device, comprising: a lens block configured such that one or more lens pins can mechanically couple to the lens block and such that the lens block can mechanically couple to a fabricated package;
