Modeof Operation
When a generator connected to a non-terminated cable emits a square-wave signal, the cable ends will always cause reflections.Depending ondistanceandfrequency, the signal can be distorted to a degree where the informa- tion becomes unreliable. However, these reflections can easily be removed by mounting the correct termina-
tion at the cable end. In the case ofDupline®thecritical distance between the genera- tor and the far cable end is 2 km and above. Consequently, if as a rule of thumb a DT 01 termination unit is mounted at the cable end when the dis- tance to the channel genera- tor exceeds 1.2 km, reflec- tions are avoided.
Note 1:
In case ofbranches onthe cableit is only necessary to mount a second DT 01 if the distanceto the nearest DT 01 exceeds 1.2 km. In all other cases a second DT 01 should notbe mountedsince itin- creases thecapacityofthe cableandtherebyreduces the transmission distance.
Note 2:
The DT 01istheonlyunit which can remove reflections and consequently cannot be replaced by other Dupline® modules.
