7 AEROSPACE / WHITE PAPER CONNECTING THE FUTURE OF FLIGHT FIG 3: Mini-ETH Cable Weight Comparison (pounds/100 feet) TE TECHNOLOGIES FOR SINGLE PAIR ETHERNET (CONT.) Looking forward, the TE Mini-ETH roadmap anticipates support for 1 Gbs and 10 Gbps data speeds, links up to 40 m (131 ft) long, and frequencies over 750MHz. The roadmap also includes new connector designs to accom- modate higher frequencies and speeds—and already envisions 1000BASE-T1 for aerospace over longer run lengths. Given likely develop- ments in ARINC standards, Mini-ETH cables are also provisioned for future operation up to 1,000 Mbps. Connectors Complementing the weight savings of two-wire cabling, Mini-ETH connectors reduce weight as much as 41 percent weight savings compared to typical D-sub connectors. The Mini-ETH connector design is based on the success of TE's 369 series connectors, a family of EWIS-compliant rectangular connectors that provide a robust solution in a small envelope. This design was based on TE's DEUTSCH DMC-M series connectors, the classic modular cabin and avionics design used in aerospace applications for nearly three decades. In addition to compactness, the 369 series connector design features internal latching and an ergonomic push-button feature that reduces installation time. Mini-ETH connectors employ standard Mil-Spec AS39029 contacts and utilize a miniaturized, robust design intended for harsh environments and high vibration. These miniaturized contacts are particularly robust against vibration. The connector shell is constructed from rugged materials with strength similar to steel but 40 percent lighter. The combination of composite materials and machined contacts accommo- dates temperatures between -55 °C (131 °F) and up to 175 °C (347 °F) for use inside and outside a cabin at altitudes up to 16,764 m (55,000 ft).
