The cable industry under economic and financial crisis conditions


The authors analyze the effect of the financial crisis on the decline of investment activity, demand and industrial production, specifically the recession influence on the cable and wire production in Russia and other CIS countries. In the second quarter of 2009 some growth of cable production output is noted according to the reports of the cable plants.

Optical fiber fabrication technologies. Review of recent developments


In this paper the key fabrication technologies for Telecom and Specialty Optical Fiber are described. A number of novel processes which allow improvement of the process performance, reduction of the fabrication cost and increase of the flexibility are introduced. Such recent innovations include a novel VAD process, a high productivity OVD cladding process, a novel Sand cladding technology (SCT) for telecom, PCF and multi-core fibers, and finally a disruptive doped sand fiber core technology.

Key words

Optical fibre, fabrication technologies, preform, sand cladding technology, fiber drawing, test, VAD, PCVD, MCVD, FCVD, OVD Clad, APVD, RIC/RIT, SAND.
