Communication cables. Specifications for test methods - Electrical test methods. Characteristic impedance, input impedance, return lossWhat is BS EN 50289 1 11 Electrical test methods on communication cables about? BS EN 50289 1 11 is a safety standard on communication cables. BS EN 50289 1 11 details the test methods to determine characteristic impedance, input impedance and return loss of cables used in analogue and digital communication systems. BS EN 50289 1 11 is to be read in conjunction with EN 50289 1 1, which contains essential provisions for its application. Who is BS EN
