TE CONNECTIVITY Mini-ETH single pair ethernet system for commercial aircraft provides weight savings, more bandwidth and simpler installation and maintenance by using proven technologies from other markets. System provides up to 73% weight savings in cables and up to 41% weight savings in connectors compared to standard eight-wire cables and rectangular connectors. Using ethernet over single pair protocols derived from the automotive market, products deliver weight savings by employing a two-wire cable design, which was recently standardized under the ARINC 854 cabin equipment network bus standard.
