LaneLink DDR InfiniBand cable assemblies

Molex Inc. has developed DDR cable assemblies that increase system speeds while improving signal quality and lowering overall costs.

Based on the DDR specifications by the InfiniBand Technology Group, Molex's LaneLink DDR InfiniBand cable assemblies are suitable for server storage applications including SAN switches, routers and server storage racks as well as RAID devices. The new assemblies provide system speeds up to 40Gbit/s over eight differential cable pairs (four channels) and improved cable signal integrity vs. standard four channel InfiniBand cables.

"Molex created the LaneLink DDR InfiniBand assemblies to meet the increased industry requirements for greater system performance and scalability," said Brad Schoester, associate product manager at Molex. "We are committed to driving the development of new industry standards such as InfiniBand and groundbreaking interconnect products. Molex's new DDR InfiniBand cable assemblies provide superior quality through improved manufacturing methods and by reducing EMI emissions."

The LaneLink DDR InfiniBand cable assemblies include a new paddlecard offering improved signal integrity over the previous edge card, a PCB straddle-mount connector. The PCB receptacle, with its die-cast frame featuring unitary latch posts and screw attachment to the PCB, provides isolation of cable loads from the SMT solder tails. Multiple latching versions including squeeze, lanyard and jackscrew are available for greater flexibility in system design and cable routing. Moreover, decreased assembly time results in reduced costs.

The InfiniBand architecture is an approach to I/O technology created by computer manufacturers to address the need for greater scalability, reliability, availability and performance in and around servers.
