Supply of fibre optic converters to the Servei Català de Trànsit

Equipos de Telecomunicación Optoelectrónicos, S.A. (EQUITEL) has the supplied real time video transmission systems over one single optical fibre, between ACESA, AUCAT and the Servei Català de Trànsit control centres (Catalonian Traffic Service)

October 1, 2007

The system D200 has been chosen for the transmission of 128 video signals between ACESA control centre (in Granollers) and the Servei Català de Trànsit over one single fibre, as well as 32 cameras between AUCAT control centre and the Servei Català de Trànsit.

By using CWDM technology (8 wavelengths), the system D200 allows the optimisation of the number of fibres available. It can transmit up to 128 uncompressed 10-bit digital video signals in real time. Furthermore, it can transmit up to 288 data signals RS-232, RS-422, RS-485, audio HiFi and contacts ON/OFF.

The basic configuration of this system consists of 16 uncompressed real-time video signals, using 2,5 Ghz bandwidth for each transmitted wavelength, and allowing in the future the multiplexing of up to 256 video signals using DWDM techniques (16 wavelengths).
