- Delay Spread and Time Dispersion Estimation for Adaptive OFDM Systems
- Time dispersion is one of the most important characteristics of the wireless channel. The knowledge about the time dispersion of a channel can be used for designing better systems which can adapt themselves to the changing nature of the transmission medium. In this paper, algorithms for estimating the time dispersion...

- Demonstration of a Tunable-Bandwidth White Light Interferometer Using Anomalous Dispersion in Atomic Vapor
- Off late, the design of a white-light-cavity has been proposed using negative dispersion in an intra-cavity medium to make the cavity resonate over a large range of frequencies and still maintain a high cavity build-up. This paper presents the first demonstration of this effect in a free-space cavity. The negative...

- Fractional Rate Phase Detectors for Clock and Data Recovery
- The use of optical fiber as a transmission medium in communications networks allows very high bandwidth to be achieved. However, dispersion effects within the fiber require that the data be regenerated periodically. Optical links typically convert from the optical domain to the electronic domain to perform the regeneration and then...

- Count Data Models in SAS
- Poisson regression has been widely used to model count data. However, it is often criticized for its restrictive assumption of equi-dispersion, meaning equality between the variance and the mean. In real-life applications, count data often exhibits over-dispersion and excess zeroes. While Negative binomial regression is able to model count data...

- Calculating Fiber Loss and Distances
- Fiber optic networking can be a daunting undertaking, but it really is not as difficult as it seems. Understanding factors such as fiber modes, fiber launch power, receive sensitivity, fiber cable attenuation, and fiber budgets will make your fiber networking installation projects run much smoother and more efficiently. Even though...

- High Fiber Diet (exe)
- Fiber falls into two general categories: water-soluble (found mostly in oats, fruit, and legumes) and water-insoluble found mostly in grains and vegetables. As each type of fiber has different benefits, most people on high-fiber diets are advised to increase their intake of foods that feature both soluble and insoluble fiber....

- Frequently Asked Questions about Customer Owned Dark Fiber, Condominium Fiber, Community and Municipal Fiber Networks
- Dark fiber is optical fiber, dedicated to a single customer and where the customer is responsible for attaching the telecommunications equipment and lasers to "light" the fiber. Traditionally optical fiber networks have been built by carriers where they take on the responsibility of lighting the fiber and provide a managed...

- Inspection and Cleaning Procedures for Fiber-Optic Connections
- Clean fiber optic components are a requirement for quality connections between fiber optic equipment. One of the most basic and important procedures for the maintenance of fiber optic systems is to clean the fiber optic equipment. It is important that every fiber connector be inspected and cleaned prior to mating....

- Coherent Optical Frequency Transfer Via 110-Km Urban Fiber Network
- Optical frequency at 1542 nm was coherently transferred over a 110-km optical fiber using an urban fiber network (JGN2) between Tsukuba and Kashiwa cities. The phase fluctuation induced by the fiber length fluctuation was actively reduced by stabilizing the fiber length using a fiber stretcher and an acousto-optic frequency shifter....

- Network Monitoring Using Traffic Dispersion Graphs (TDGs)
- Monitoring network traffic and detecting unwanted applications has become a challenging problem, since many applications obfuscate their traffic using unregistered port numbers or payload encryption. Apart from some notable exceptions, most traffic monitoring tools use two types of approaches: keeping traffic statistics such as packet sizes and inter-arrivals, flow counts,...

Conscientious network and security managers either provided tight physical security for cabling or used fiber as an alternative. Many network managers considered fiber relatively safe due to the perceived challenges associated with tapping into an...
