1742257-2

The 1742257-2 by TE Connectivity AMP Connectors redefines excellence in Terminals - Specialized Connectors for high-speed data center applications. Designed for 400G Ethernet backbones, this interconnect solution delivers unprecedented signal integrity with less than 0.5dB insertion loss at 56GHz.Featuring Keyboard Switch architecture, the contacts utilize selective gold plating over palladium nickel, achieving 85 maximum contact resistance. When deployed in QSFP-DD assemblies, it demonstrates superior return loss characteristics compared to traditional designs.With Solder technology, the termination process creates oxygen-free joints that maintain stable impedance across 10,000 thermal cycles. Automated X-ray inspection ensures each connection meets IEEE 802.3ck specifications for 800G readiness.
