Description

Genuine Amphenol 100G QSFP loopback adapter modules provide the ideal 100-Gigabit Ethernet rated port testing solution for QSFP28 enabled ports (28.0 Gbps x 4 channels). This low-profile passive QSFP 100G loopback cable features typical insertion loss (attenuation) characteristics of a mere 0dB; consuming no more than 0.0 Watts of power in the process. Compatible with both copper and optical QSFP28 enabled ports, our loopbacks perfectly replicate the performance range typical of a short-length QSFP 100-Gigabit connection between the latest QSFP28 equipped adapter cards, blade servers, routers, and switches. Protocol-independent design ensures compatibility with all present and emerging signal standards, including 100-Gigabit Ethernet, 4x EDR InfiniBand, SONET and beyond.
