The GORE SFP+ copper cable assemblies offer a more reliable, efficient, and economical alternative to fiber optic modules for transmitting 10 Gbps data at distances up to 25 meters. The assemblies comply with the SFF-8431 standard while providing reduced jitter, a very low latency, and a maximum signal eye opening. Additionally, they provide the highest performance with a lower dielectric constant, lower loss, tighter impedance control, and a wider bandwidth. Through the use of a proprietary expanded PTFE dielectric, the company achieves a smaller cable size for a given conductor or a larger conductor in a specific twinax diameter. These cables are completely RoHS-compliant, even with some exemptions that have been recently eliminated.
