The passive copper cables require no additional power to ensure quality connectivity. The cables are compliant with SFF-8685 specifications and provide connectivity between devices using QSFP+ ports. Each QSFP+ port comprises an EEPROM providing product information, which can be read by the host system.

This integrated cable solution provides reliable transport for aggregate data rates of up to 56Gb/s. Optimizing systems to operate with Gigalight's 56Gb/s passive copper cables significantly reduces power consumption and EMI emission, eliminating the use of Enterprise Data Center (EDC) hosts.

Gigalight's unique quality passive copper cable solutions provide power-efficient connectivity for short distance interconnects. They enable 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.
