The passive copper cables require no additional power to ensure quality connectivity. The cables are compliant with SFF-8418/SFF-8419 and SFF-8685/SFF-8436 specifications and provide connectivity between devices using QSFP+ port on one end and four SFP+ ports on the other end. Each QSFP+/SFP+ 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 40Gb/s. Optimizing systems to operate with Gigalight's 40Gb/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.
