ITU-T/CCITT G.703 Telecom Balun 75 Ohm to 120 Ohm

(All True 75 ohm connectors)

=> ITU-T/CCITT G703 Telecom Mini Balun: fully shield for EMC and RFI Compliance

=> ITU-T/CCITT G703 Telecom Krone Balun IDC 3 pole series

New balun connector designed for international WAN environments. Specifically created for the ITU-T/CCITT G.703 TELECOM applications, the balun provides conversion between 75 Ohm and 120 Ohm G. 703 interfaces. The unit supports data rate up to 2.048 Mbps (E1) and is packaged in an ultra miniature enclosure.
For those of you who may not be familiar with G. 703, it is similar to T1 or DDS standards in the USA. This interface standard is used throughout the world to specify the physical and electrical characteristics which enable the interconnection of digital network components. For example G703 is the connection standard for EI services in Europe (more tutorial in upcoming issues).
This balun simply converts 75 Ohm G. 703 transmit signals to 120 Ohm signals for transmission over network, or reception by a CPE. It also converts 120 Ohm G. 703 transmit signals to 75 Ohm signals. The signals produced conform to the pulse shape requirements outlined in the standard.
