Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

  • Description

    G.703 75–120 Adapter, Female with 1.6/5.6 Coax Connectors and Transformer Isolation, 2.048-Mbps


    Quick Facts

  • Solve mismatches between coax and twisted-pair equipment.
  • Make 75-ohm (dual-coax) and 120-ohm (twisted-pair) network connections.
  • Convert bidirectionally between G.703 balanced and unbalanced interfaces.

  • Further Details

  • All feature transformer isolation for protection against ground loops.
  • Choose from models that support 2.048-Mbps or 8-Mbps speeds.
  • 2.048-Mbps models can be ordered with 1.6/5.6 dual-coax connectors.

    Make bidirectional G.703 balanced and unbalanced conversions and protect against ground loops.

    Use G.703 75–120 Adapters to connect your G.703 network to your shielded twisted-pair equipment.

    These adapters address the open network provision (ONP) requirement that European post, telephone, and telegraph (PTT) authorities offer 120-ohm twisted-pair terminations to their customers.

    Use the adapters to convert the balanced G.703 signals from your bridges and routers to unbalanced G.703 signals. So you can use your 75-ohm coax hardware and communicate with 100-ohm or 120-ohm twisted-pair equipment. The adapters convert signals bidirectionally, too.

    Setup is super easy. Just plug in the adapters. If needed, you can configure the shield connection between the 75-ohm and twisted-pair interfaces.

    The G.703 75–120 Adapters support E1 data rates to 2.048 Mbps. For sending TX and RX signals over STP cable, order the MT256A-F, which has 1.6/5.6 dual-coax connectors.

    The G.703 75–120 High-Speed Adapters support data rates to 8 Mbps.
