The passive copper cables require no additional power to ensure quality connectivity. The cables are compliant with SFF-8402 SFP28 and SFF-8665 QSFP28 standard specifications and provide connectivity between system units with a QSFP28 port on one side and up to four different SFP28 ports on the other. The cable connects data signals from each of the 4 copper pairs on the QSFP28 end to the single pair of each of the SFP28 ends. Each QSFP28/SFP28 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 100Gb/s. Optimizing systems to operate with Gigalight's 100Gb/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.
