GORE Unveils New Copper Cable Assembly for 10 Gbps Transmissions

By Jayashree Adkoli, TMCnet Contributor

W. L. Gore & Associates, a provider of cables and cable assemblies, has added a new product to its high-performance digital interconnects product portfolio, GORE SFP + copper cable assembly. These small form-factor pluggable (SFP) + copper cable assemblies are designed for high-performance computing (HPC), enterprise networking, 10 GbE applications, data centers and network storage markets.
The new SFP + copper cable assemblies are part of Gore’s 10GbE product portfolio. Gore claims that the new cable assemblies are reliable, lower power and more cost-effective alternative to fiber optic modules — for transmitting 10 Gbps data up to 25 meters.
Herb Vandeusen, Gore's product specialist for GORE SFP+ Copper Cable Assemblies, said, "Our SFP+ copper cable assemblies have been proven to be a cost-effective solution to high-performance computing applications, specifically in the 10 Gigabit Ethernet and 8G and 10G fiber channel markets."
GORE said its new SFP+ copper cable assemblies are capable of providing high-performance even with a lower dielectric constant, lower loss, tighter impedance control, and a wider bandwidth.
Key features of GORE SFP + copper cable assemblies include: low cost I/O solution for 10 GbE applications; easier routing and accessibility due to reduction in cable size; cost-effective scalability for high node count; GORE EYE-OPENER+ Conductor technology extends bandwidth, distance and density; reduced jitter; low latency; and no increase in electro magnetic interference ( EMI) emissions through enhanced EMI shielding.
The new assemblies utilize proprietary expanded Polytetrafluoroethylene (PTFE) dielectric. This helps Gore to achieve a smaller cable size for a given conductor or a larger conductor in a specific twinax diameter.
GORE SFP+ copper cable assembly’s connector is made with a high-performance, low-loss RF material, in order to reduce dielectric loss and as well provide a higher degree of impedance control through the link. It also features reduced crosstalk compared to other lossy FR-4 designs, where Flame Retardant (FR) 4 is a type of material used for making a printed circuit board (PCB).
GORE SFP+ copper cable assemblies are SFF-8431 standard compatible. SFF-8431 standard is defined by the Small Form Factor 8431 group and is primarily defined for 8 and 10G optical (limiting and linear), and short reach copper cable. These cables are completely RoHS-compliant as well.
Some of the Gore's high-performance digital interconnects line of products include: DDR and QDR InfiniBand; CX-4, GbX; AIRMAX VS; and ERmet ZD cable interconnects.
Newark, Delaware-based W. L. Gore & Associates also provides wide-range of high-performance solutions in consumer, industrial, electronic, medical, and surgical markets.
