Fibre Optic Distribution Systems - Description
A customised solution for the distribution of a reference clock can be configured to suit individual
requirements. The system can be built up from a combination of self contained DA-36 units, or the
more flexible, modular DA-35 system.
The distribution is completely analogue over fibre and the signal is reconstructed with the help of a
steep bandpass filter. Interference, such as noise and distortion, can be completely eliminated by
the filter.
The signal to noise ratio in the received signal can be almost equal, and in certain cases, better than
the input signal, even in cases where the signal is distributed hundreds of metres.
By using a fibre optic cable for transmission, a galvanic isolation is created between the transmitter
and receiver. The fibre is immune to external disturbances such as cross-talk and ESD.
The receiver has automatic gain control, which makes installation and adjustments easier. Distances
up to 2000 metres can be achieved.
