What you should know about ADSS Cable

ADSS cables. All-Dielectric Self Supporting cables. The All-Dielectric Self Supporting (ADSS) cable is a completely non-metallic structure in which the tensile load bearing elements are integral within the circular design of the cable - usually in the form of aramid yarns or stranded glass reinfroced plastic rods. The structure of ADSS Cable Typically a loose [...]

Tecnologías FTTH

Al demostrarse que la presencia de medios de transmisión diferentes a la fibra óptica plantea limitaciones relativas a la distancia y al ancho de banda, se pretende conseguir una solución en la que la fibra óptica se acerque el máximo posible al usuario final. Atendiendo a este concepto surgen las soluciones FTTH, sobre las que […]

Tecnologías HFC.

Aún conociendo que la fibra óptica es el medio de transmisión que menos atenuación con la distancia y más ancho de banda permite, también es cierto que tanto el material del que se fabrica, como su despliegue tienen un coste considerable. Debido a que en un primer momento el único despliegue que se planteaba era […]

Tecnologías xDSL

Actualmente es la tecnología más empleada como medio de transmisión en las redes de acceso. Las tecnologías xDSL se basan en la multiplexación de la señal de voz que discurre por el cable de pares telefónico, y la señal de datos aprovechando el espectro superior de este medio de transmisión que antes no se utilizaba. […]

Conservando la polaridad en los sistemas MPO/MTP

Los sistemas troncales montados en fábrica, con conectores multifibra MPO, son utilizados de preferencia y de forma creciente para los despliegues de sistemas ópticos de cableado; sobre todo en áreas de alta concentración, tales como los centros de datos. Para poder mantener unas vías bi-direccionales de transmisión, el sistema debe proporcionar una polaridad correcta que […]

Introduction to VSAT (Very Small Aperture Terminal)

VSAT (Very Small Aperture Terminal) is the best solution when terrestrial connectivity is not available or cannot meet your communication needs. Offering converged communications, always-on connectivity anywhere and anytime across multiple geographies, our VSAT is a two way satellite ground station with a dish antenna smaller than three metres. VSAT gives you the freedom to […]

What splitter structure you should have in FTTH network centralized or cascading

FTTH currently developed very fast in South America and Africa, however, many new comers are curioused about how many splitters should i have in FTTH network. PON is the basic structure for FTTH network, PON is short for Passive Optical Network. It consists of OLT, ODN (Splitter) and ONT. From the structure, splitter placement in […]

Introduction to Microducts for Air Blown Fiber ABF

Based on Telcordir GR-3155. Microducts are typically small-diameter, flexible, or semi-flexible ducts designed to provide clean, continuous, low-friction paths for installing optical cables that have relatively low pulling tension limits. The microducts are compatible with existing construction designs and building configurations for both riser- and plenum-rated applications, including cable blowing apparatus. Allow cables to be […]

How to install air blown fiber

When the Telecom operators, ISPs are designing and installing optical fiber cables, they need to have some spare fiber or spare space for future application, Air Blown Fiber (ABF) systems are well developed, available from multiple vendors and some installers are trained and experienced in their installation. The hardware and installation is somwhat different from […]
