At around $3 per each genre-based channel package, VA-based KlowdTV’s streaming programming bundle seems unbelievably affordable. The platform, which went live less than a year ago, recently doubled its package offering with the addition of a 6-channel global news package including Bloomberg TV and Sky News International, and a 7-channel entertainment package including YouToo America […]

Tipos de conexión
Existen diferentes opciones desde la tecnología para acceder al servicio de acceso a Internet, siendo las más frecuentes aquellas en las cuales el acceso hasta el nodo del Proveedor de Internet se efectúa utilizando como medio de transmisión las redes preinstaladas para la provisión de otros servicios (como por ejemplo el servicio de telefonía o […]
Kriterien zur Auswahl eines optischen Reflektometers (OTDR)
Dieses White Paper enthält wichtige Informationen zu optischen ZeitbereichReflektometern (OTDR). Weiterhin erläutert es Neueinsteigern auf dem Glasfasermarkt für Telekommunikationsanwendungen die Kriterien zur Auswahl eines OTDRs, das ihren spezifischen Testanforderungen gerecht wird. Was ist ein OTDR? Ein OTDR ist ein Glasfasertester zur Charakterisierung von optischen Netzwerken, die Telekommunikation sanwendungen unterstützen. Die Aufgabe des OTDRs besteht darin, […]
Fiber-optic cable installation tools for aerial, underground projects
General Machine Products Company recently introduced reel-handling accessories for the aerial and underground placement of fiber-optic cable. “These components—The Pole Mount Spindle, the Reel Buck, and the Reel Caddy—are uniquely engineered to make fiber-optic cable installation safer and more productive,” the company said. “All of the accessories feature durable steel construction for years of rugged […]
Sharks and Sub Marine Cable
Sharks are not the nemesis of the Internet, says the International Cable Protection Committee (ICPC), which has released an analysis of the main causes of submarine cable breaks. Essentially, sharks and other fish were responsible for less than one per cent of all cable faults up to 2006. Since then, no such cable faults have […]
Arc Fusion Splicing of Photonic Crystal Fibres
Arc fusion splicing is an established method for joining optical fibres in communication networks, ensuring splice loss down to 0.05 dB and excellent reliability. Telecom fibres are covered by IEC 60793 and ITU-T G.651.1-G.657 standards, with common material (fused silica) and cladding size (125 μm). Splicing equipment for these fibres is widely available. Fusion splicing […]
NEXT-GEN COMMUNICATIONS FIBER: Multilevel modulation formats push capacities beyond 100 Gbit/s
Since the late 1980s, fiber-optic networks have steadily become the bedrock for the ever-expanding global telecommunications system. Early fiber-optic links, such as the eighth transatlantic telecommunications cable (TAT-8) installed in 1988, were relatively simple systems by today’s standards and used on-off signaling to transmit a few hundred megabits per second (Mbit/s) over a single optical […]
Three Main Factors Affecting FTTx Deployment
When operators weigh up their FTTx architecture options, a number of factors will have to be taken into account. These include what assumptions are made about customers’ bandwidth requirements; the topology of the existing legacy network; the level of competition from cable operators; the cost of laying fibre to the node compared with running it […]
FTTN architectures and performance
Overview A fibre-to-the-node (FTTN) architecture comprises a fibre-optic link between the central office and an intermediate distribution point. From this distribution point, the home and/or building is served with voice and data through either a wireline or wireless connection. If the existing copper plant is used for the ‘final drop’, which is usually the case […]
OSP Outside plant construction
Overview The deployment of a PON architecture requires a number of outside plant components, including the optical distribution frame, splitters, splicing closures, and wall-mounted boxes on the home or the building. It also requires fibre-optic cables with specific performance characteristics, both in the indoor and outdoor environment. The selection of cables and associated components, as well as how […]
