20140248057 | WDM Mux/DeMux on cable and methods of making the same - Techniques for WDM Mux/DeMux on cable and methods of making the same are described According to one aspect of the present invention, a unit designed to provide multiplexing or demultiplexing (Mux/Demux) functions is implemented on cable. In other words, the Mux/Demux unit is coupled by a multi-fiber cable to a system (e.g., a system rack for router or switch that has multiple pluggable transceiver slots). | 09-04-2014 |
20120237222 | Micro Free-Space WDM Device - Techniques for designing optical devices that can be manufactured in volume are disclosed. In an exemplary an optical assembly, to ensure that all collimators are on one side to facilitate efficient packaging, all collimators are positioned on both sides of a substrate. Thus one or more beam folding components are used to fold a light beam up and down through the collimators on top of the substrate and bottom of the substrate. | 09-20-2012 |

20090242772 | Motor Driven Variable Optical Attenuator with IR Sensor Closed-loop Control - Attenuators used to regulate optical signals are disclosed. According to one aspect of the present invention, an assembly including an IR source and an IR sensor is provided to sense blockage of optical signals transmitted between two collimators via a fixed common light blocker that is driven by a stepper motor. The movement of the light blocker is sensed by a sensing assembly including an IR source and IR sensor. By detecting the photocurrent from the IR sensor and a feedback circuit, the attenuation of the optical signals can be well controlled. | 10-01-2009 |
