Quadrax/Twinax Passive Equalizer

Passive Equalizer contacts operate up to 12.5 GBPS and fits inside a standard Size 8 twinax/quadrax contact cavity for all connector formats. The passive equalizer requires no external power and acts like a high pass filter operating over an extreme temperature range. This compensates for the frequency dependent cable loss and helps to re-open the eye pattern on long cable runs allowing to pass higher data rates, for a given cable length, or extend the length of your cable at existing data rates. Equalization is an important tool in any digital engineers toolkit.

Quadsplitter & In-Line Quadsplitter

Smiths Interconnect offers a complete series of connectors available to utilize the Quadsplitter technology with MIL-DTL-38999 Series, combining the signal integrity of Twinax cables and the connection density of Quadrax.

Rugged D-Sub with Twinax/Quadrax contacts

High impedance D-Sub connectors are designed to ground the outer shield of a twinax or quadrax contact directly to the shell of the connector. A multi-finger ground spring fixed around the shell provides a multi-point contact engagement that affords superior EMI shielding. The end result is an extremely low contact resistance when measured from the contact outer body to the connector flange, ensuring minimal RF noise and high durability of over 500 mating cycles.

ARINC 801

With its standard 1.25 mm ferrule and sleeve, the ARINC 801 terminus is designed for both multimode and single-mode applications. For the pull-proof design, the cable jacket is crimped on an external body and a floating mechanism avoids any loss of performance when pulling on the cable. This feature allows for the use of the connector without a backshell. Standard connector formats include MIL-DTL-38999 type, MIL-DTL-83527 type, ARINC 600 and ARINC 781.
