Methods and Components for Optical Contention Resolution in High Speed Networks

Pagination or Media Count:
The effort in construction of the CRO module included this month work in further development of the particular submodules, their characterization and fine tuning of design parameters. Moreover, design of the complete physical box with its inputs, controls and thermal considerations has been in progress. The optical amplifiers cooling and the mechanical stability of the various parts were taken into account. Detailed measurements of the back reflections were performed and improvements in assembly or integration techniques derived. We keep in mind that the CRO box will be transported to Stanford and must be built not as a laboratory demo, but rather as a transportable item. This requires securing components and fibers, and affects the overall design of the box. Emphasis in the assembly effort is on compatibility of the completed device with system performance requirements. This includes minimization of losses and reduction of back reflections. In the single polarization preprototype this also includes methods to minimize polarization cross-talk.
