Fiber optics - planning & installation

"Fibre in the Loop" Konzept von UPC-TelekabelOur fiber runs twice around the earth

Our complete cable length brought in until today comes to approx. 1200km. Which corresponds to a fiber length of approx. 80.000 km. Mainly in the urban areas of Vienna, but also cross-country (Lower Austria) approx. 100km through the Viennese forests.

Europe most modern glass fiber network of UPC Telekabel consists of two bi-directional rings. If a cable interruption occurs, the two redundant rings will be united and will act as one to keep up further operation. At 5 different places the two backbone rings are connected to outer distribution-rings.

Based on many years of experience with already executed projects Ing. Witke Ltd. offers a perfectly trained team with practical experience for many years for all request in the field of the fiber optics. Our technicians already manufactured over 45.000 checked fusion splices - each with minimum absorption.

In the picture on the left a particularly trained employee of engineer Witke is operating on the installation of a 19 inch patchfield in a UPC Telekabel backbone glass fiber station. 384 glass fibers are attached here.

The equipment:
  1. Two fully air-conditioned, dust free splice trucks with emergency power supply. The vehicles enable work at all climatic conditions and have optimal lighting conditions inside.
  2. Two fully automatic glass fiber splice units
  3. An OTDR status measuring instrument
  4. Three portable OTDR measuring instrument of types  CMA4500,  FTB300 and  Fot-910
  5. Wattmeter: All devices capable for all types of fiber and wavelengths.

In headend stations these module cassettes are used to connect glass fiber strands.

In the box which is shown on the left side 24 veins (diagonal cross section contact) can be stuck on SC/APC clutches.
