to  G.703 Mini Balun series, fully shield for DDF)
Part No : Description :
ITU-T/CCITT G703 Mini Balun: (TRUE 75 OHM connectors)
Temple Star Inc. ITU-T/CCITT G.703 Mini Balun fully shielded design ideal in telecom applications where size and space are restricted to small dimension.  Ideal for panel mounting or cable mounting and feature IDC termination which allow installation without special tools.  Surface mount transformers inside are replacements to traditional coaxial, ceramic and printed circuit board baluns.   In addition, conversion to twisted pair cabling enables the use of high density IDC modules in Digital Distribution Frames (DDF) thus significantly decreasing wiring densities.

* 75 ohm coax to 120 ohm twisted pair
* Data Rate to 2.048 mbps
* Speed range 2 - 8 Mbit/s
* Bi-directional signal conversion
* No AC power or batteries needed
* Ultra miniature exclosure, fully shield for EMI
