Deutsche Telekom to use Micro-OTDR for FTTH networks project

Deutsche Telekom has launched a fibre optic development pilot project in Dresden aimed at improving Internet. The outcome of this pilot project will be incorporated in the expansion of Deutsche Telekom’s installation of Fibre to the Home (FTTH) networks.

The installers are faced with the challenge of extending or replacing the previous copper technology with optical transfer technology. An important method of inspection for this is the optical time domain reflectometer (OTDR).  Each installation team must be equipped with an OTDR in order to measure and document the parameters of the optical fibres laid.

For the additional development of the FTTH network, Deutsche Telekom decided on the Yokogawa AQ1200 Micro-OTDR  which, for the first time, enables measurements with a wavelength of 1650 nm to be taken with a compact test instrument.

The measuring wavelength of 1650 nm was one of Deutsche Telekom’s requirements in order to take measurements during operation and in doing so not interrupt data transfer via shorter wavelengths. The 1650 nm wavelength is allocated exclusively for measurement purposes and carries no normal user traffic.

The portability of the Micro-OTDR, the luminosity and brilliance of the display, together with the intuitive controls, ensures that technicians not necessarily experienced in optical transfer technology can obtain results quickly.
