Amphenol Corporation Amphenol SF-QSFPLOOPBK-001 QSFP+ 40G Loopback Adapter Module for QSFP/QSFP+ Port Testing - 0dB Attenuation & 1.5W Power Consumption [Copper+Optical Ready] SF-QSFPLOOPBK-001

Genuine Amphenol QSFP+ loopback adapter modules provide the ideal 40-Gigabit rated port testing solution for both QSFP and QSFP+ enabled ports. This low-profile active QSFP+ loopback cable features typical insertion loss (attenuation) characteristics of a mere 0dB; consuming no more than 1.5 Watts of power in the process. Compatible with both copper and optical QSFP/QSFP+ enabled ports, our loopbacks perfectly replicate the performance range typical of a QSFP+ 40-Gigabit connection between QSFP+ equipped adapter cards, blade servers, routers, and switches. Protocol-independent design ensures compatibility with all present and emerging signal standards, including 40-Gigabit Ethernet, QDR InfiniBand, and beyond.
