The experimental results of a hybrid, fiber-remoted millimeter-wave/free-space optical communications link are presented. Multi-Gb/s data rates are independently demonstrated using millimeter-wave and optical carriers.
A 40-Gbps free-space optical communications (FSOC) link architecture incorporating high-sensitivity modems and a high-dynamic range optical automatic gain controller (OAGC) is presented. The architecture leverages 10-Gbps modems, each supporting 10-Gigabit Ethernet, to ease interfaces to commercial network systems. The 10-Gbps modems employ return-to-zero differential phase shift keying waveforms...
A 150 km free-space optical (FSO) communication link between Maui (Haleakala) and Hawaii (Mauna Loa) was demonstrated by JHU/APL and AOptix Technologies, Inc. in September 2006. Over a 5 day period, multiple configurations including single channel 2.5 Gbps transmission, single channel 10 Gbps, and four wavelength division multiplexed (WDM) 10 Gbps channels for an aggregate data rate of40 Gbps were...
Introduction Retinoblastoma (RB) is the most frequent malignant eye tumor in childhood. In developing countries advanced stages are common. The purpose of this paper is to present our 21-year clinical experience with metastatic extra ocular RB patients treated with 5 different chemotherapy schemas at a single Mexican Pediatric referral center. Materials and methods A retrospective analysis was carried...
