A 3.2×3.0 inch2 optical type fingerprint scanning flat panel is designed and implemented. The driving system is based on the passive pixel sensor (PPS) array with amorphous silicon (a-Si) TFT technology. The sensing layer of the optical sensor is composed of the Si-nanocrystals (Si-NCs) embedded in the dielectric material. The pixel density is over 500 PPI and the gray levels are up to 256 with excellent...
This paper describes the need for optical interworking between DWDM transport equipment and transponders provided by different vendors and possibly managed by different operators - so-called aliens. It discusses technology, benefits and standards progress.
This paper explains the key operator need for remotely managed, coloured transceivers in client routers and switches, carried directly over DWDM networks as 'alien wavelengths' and describes a demonstration including in-band OTN based management.
