Description / Abstract:

This specification provides a test methodology for characterizing the performance of aviation-grade connectors that support Ethernet data bus applications. Specific electrical parameters must be measured to determine a connector’s suitability to support sustained, error-free Ethernet communications.

Unlike connectors designed for the telecommunications market, where connector form factor (RJ-45, etc.), cable type (Category 5, Category 6, etc.), and wire termination techniques are defined in the ISO and TIA standards, aviation-grade connectors that may be considered for use in high-speed data applications are available in a wide variety of form factors. Subtle differences in physical attributes such as connector pin patterns, contact length, signal assignments versus contact positions, wire terminations (wire strip length), and shielding can have a significant effect on connector performance.

With the vast combinations of connector and aviation-grade data cable types available in the marketplace, an industry-approved qualitative test method is required to assist the designers responsible for making part selection decisions.

This specification is not intended to replace component level test methods, such as ANSI/TIA-568-C.2, that may be used by the connector or cable manufacturer. The method herein focuses on Ethernet link-level performance rather than componentlevel performance. The outcome of the test will determine if a specific aviation-grade connector and aviation-grade cable, when connected in a concatenated link, will meet its intended function.

The test procedure and performance criteria in this document are limited to 1000BASE-T Gigabit Ethernet (as defined in IEEE 802.3) data applications.
