Adapter Balun G703 RJ45 Female to BNC Female.Webb’s dual balun adapter is a miniature G.703 balun that allows 75 ohm coax hardware to communicate with 120 ohm twisted pair equipment. It supports E1data rates to 2.048 Mbps and E2 to 8.448 Mbps. The dual balun receives 75 ohm signals and converts them to 120 ohm for transmission over a network. The signals output by dual balun are scaled to match the pulse shape requirements specified by the CCITT G.703 standard.
