    Abstract: A method for utilizing a delay lock loop to cover a wide delay range. In one method embodiment, the present invention receives a reference clock pulse. Next, in a first loop, a phase variation is adjusted between the feedback clock pulse and the reference clock pulse utilizing a coarse delay in conjunction with a first fine delay. The resulting pulse is then output to a chip delay and then sent back to the delay lock loop as a feedback clock pulse. Additionally, in a second loop, the phase variation is adjusted between said second loop and said first loop utilizing the coarse delay in conjunction with a second fine delay, wherein the second fine delay has a delay range for adjusting the phase variation which overlaps the delay range of the first fine delay of the first loop.

    Abstract: A terminus for a fiber optic cable includes a ferrule. In one embodiment, an optical fiber of the cable passes through a central bore of the ferrule and is attached to a lens seated in a conical or cylindrical seat formed in an end surface of the ferrule by an epoxy. In a second embodiment, an optical fiber of the cable passes through the central bore of the ferrule. Next, a cap sleeve with a lens therein is slid over and attached to the ferrule such that the lens abuts or is attached to the optical fiber. In either embodiment, an inspection slot may optionally be formed in the ferrule and/or the cap sleeve to allow a technician to inspect the state of the attachment and/or abutment and/or spacing of the optical fiber and lens.
