Railway Signalling Outdoor Indoor Cables External Data Transmission Cables 1. For axle counter data between the ACE and the EAKs the transmission is over a voice frequency carrier, and hence twisted pair cable is required. Because the transmission distances are restricted to maximum 2 km, it is not necessary to individually shield each pair, and […]
