A chassis includes a plurality of continuous wave lasers each operable to emit a continuous wave optical beam at the same power as the other lasers, and a plurality of optical couplers operable to input the continuous wave optical beams of the same power and output a plurality of continuous wave optical beams at different powers. The chassis further includes a plurality of optical assemblies operable to modulate the continuous wave optical beams of different powers into a plurality of modulated optical signals at different powers and couple the modulated optical signals onto different length optical mediums so that lower power ones of the modulated optical signals are coupled to shorter ones of the optical mediums and higher power ones of the modulated optical signals are coupled to longer ones of the optical mediums.

An optical patch unit is adapted for mounting in or on an optical equipment rack and facilitates a migration from one optical shuffle box or topology to another. The optical patch unit simplifies the replacement of an optical shuffle box, in some cases allowing a phased migration that minimizes system down-time. The optical patch units described herein include passive optical patch panels. Chassis card and optical shuffle connections are terminated at the passive optical patch panel, making it possible to simplify the cabling between the chassis cards and the optical shuffle box. Once installed, chassis card cables do not need to be manipulated at all during subsequent optical shuffle maintenance procedures. Other optical patch units described herein include active optical patch units, which make the migration process less dependent on human intervention and can further reduce system down-time.
摘要:
The present invention relates to an improved process for producing highly ordered nanopillar or nanohole structures, in particular on large areas, which can be used as masters in NIL, hot embossing or injection molding processes. The process involves decorating a surface with an ordered array of metal nanoparticles produced by means of a micellar block- copolymer nano-lithography process; etching the primary substrate to a depth of 50 to 500 nm, where the nanoparticles act as a mask and an ordered array of nanopillars or nanocones corresponding to the positions of the nanoparticles is thus produced; using the nanostructured master or stamp in a structuring processes. Also the finished nanostructured substrate surface can be used as a sacrificial master which is coated with a continuous metal layer and the master is then etched away to leave a metal stamp having an ordered array of nanoholes which is a negative of the original array of nanopillars or nanocones.
