CCITT G.703 balun
  • Product Number : CCITT Patch Panel 2U
  • Product : 2-8-34 Mbit/s
DESCRIPTION :

The CCITT G.703 Balun panel matches multiple sets of dual 75 ohm coax connections to multiple 120 ohm twisted pair connections. Supporting data stream to three speed versions:
- 2-8 Mbit/s for E1/T1 and E2/T2,
- 2-8-34 Mbit/s for E1/T1 to E3,
- 34 to 155 Mbit/s for E3 and higher.

The patch panel bi-directionally match, not only signal impedance, but also the pulse shapes of the signals according to the CCITT G.703 standard.match.

This Patch Panel is a 2U size: all connectors are on the same side.
Our standards panels are with 8, 16, 20 or 24 ports. If special request, please contact us.
