Description

QSFP-100G-DACH cables are high-speed, cost-effective alternatives to fiber optics in InfiniBand 100Gb/s EDR applications.

The QSFP28 passive copper cables contain four high-speed copper pairs, each operating at data rates of up to 25Gb/s. Each QSFP28 port comprises an EEPROM providing product information, which can be read by the host system

The unique quality passive copper cable solutions provide power-efficient connectivity for short distance interconnects. It enables higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.

Rigorous cable production testing ensures best out-of-the-box installation experience, performance and durability.
